Hello all,
I've been following along with this coupler discussion because I'm in
a similar boat. I would have loved to have electro auto make the
coupler but they don't have my pattern and they don't seem interested
in my business. So, I thought I would have it made myself. I'm
capable of doing the adapter plate myself but the coupler is a little
technical.
Anyway, my problem is that the bolt circle for the flywheel on my car
has a diameter of 63 mm. There are 8 bolts. Looking at a quick cad
drawing of the bolt circle along with various QD bolt circles it is
impossible to fit the two unless you go up to the SF size QD bushing
(which is nice with it's 900 ft/lb rating) but, the SF size bushing is
getting really large and seems to want 2.06" of shaft to grip.
I think my FB4001 motor only has about 1.5" to grip (please correct my
if I'm wrong). I haven't removed the old transmission from my motor
yet so I'm not sure, I'm just going by the advanced DC drawing that I
have.
So, my questions are:
1. Is it that critical that there is motor shaft in all of the bushing
(ie can there be 1/2 at the outside edge that is empty)
2. Is there another manufacturer of similar bushings that has
different bolt circles.
The other solution I guess is to make the bushing from scratch. I
like Jeff's solution but it would be simpler to just buy a bushing and
I'm not sure I can fit that much inside the flywheel bolt pattern.
Anyway, any input would be appreciated.
Thanks!
-Jeremy

Hi EVerybody;
I You Tubed the Volt, what a Joke! The one where the woman got in and
drove it out of the driveway. Ha Ha. Sounded like a Chicago, North Shore and
Milwaukee Intterurban Railroad car, or a Chicago, South Shore and South Bend
Train, circa 1928!! As a trolley fan, sounded nice Ha Ha!!You Chicagoland
guys USED to hear the sounds of Heavy electric rail. Or the Illinois
Central's 1500 volt "Green Cars"All fond memories. IF that gal had my Jetta,
she coulda unplugged it, flipped the flap shut, on the gas filler, camera
lingering on my " Boycott OPEC Use electric fuel"sticker, climbed in, put
'er in second and glid out the driveway silently! And gone down the road at
35-40 mph, out of the pix!Hell! The Jetta is a better LOOKING car than the
ReVOLT, anyhow. She coulda picked up 3 of her friends in the Jetta, to go
shopping or to refinance her SUV( Mc Mansion) house. I think the Volt is
UGLY as sin, anyhow. Now IF they had taken the EV-1 and fitted it with a
small gas jenny for AFTER you have gone OVER 100 miles and needed a boost?
IF you could leave it at home UNTIL you needed the range and you could stuff
it aboard? A EV-2 MIGHT be a 4 door, and redesigned to have less tunnel down
the middle, but still have a good C of D. EV-1 LOOKED nice, after all, form
follows function. A EV-3 Wagon? But none dare call a Station Wagon a Station
Wagon, nowadaze!
But ya all know General Murders is gunna stonewall the electric car as
long as they can. Gas is only going higher, as you read this it MUST be 100
bux a barrel for oil, today?Looking at Lutz and his ilk I think" Would YOU
buy a used car from this guy? Ha Ha, or NEW car from them, ether?
The only way any significent change will be another 911, or Pearl Harbor,
WAR, of our starting ,when the Oil Folks over where it is HOT all the time
say;" Screw You" and turn off the taps. Very few planes flying. Amtrak
struggling to keep a 1940's system going. Oh! we're all set in the Least
Coast where the lines are electric now. BNSF and the Union Pathetic
stringing up catenery, GM's Electro Motive div. building electric
locomotives. Well, GM spun off EMD a few years ago, and the engines will
come from Canada as they closed La Grange , Ill. plant "Home of the Diesel
Locomotive".They should turn that place into a museum! Been there. Awesome
seeing Diseasels born! Of course Generous Electric could build electrics
again, too.
Back on topic a little. Maybe Lee Hart will have Sunrise reserected9Keep
those checks going!) before GM gets it's shit together?Or Jerry Dycus has
Freedom going? Freedom is a nitch market, but to him a thousand car order
would be a HUGH one. To GM they wouldn't bother?We HAD 1000 EV-1's
already.Tesla?We'll see.He's having issues, too. But they have money to
throw at them, big time!
The Electric's time is hear, IF we can overcome politics, get all the
Good Stuff together, and get it to market before the apoloplipse?
Somebody commented that changing to electric COULD wreck the "industry"
Well, teamsters wrecked some of the first steam locomotives, reasoning that
they would put them out of work?The buggy whip guyz had to change, too. when
Auyto-mobiles came on the scene, too. The folks that make my beloved 78 rpm
records HAD to change 50 years ago. Of course THEY have learned well; The
Format of the Week" concept. CD's, DVD's, stuff changes every few minutes.
But how much of this crap will WORK in 100 years from now, like my Victor
1907 records will STILL play? I get the styluses(needles) to play them on
line, ironicly enough.You can still BUY a 78 rpm turntable for your
listining pleasure!O.T. a tad, here, go to
http:/loudcity.com/station/440.aspx , click on "Radio Dismuke". Enjoy the
snappy upbeat tunes, good for building/driving electrics by, Jettas to
Acelas!I am happy with something I like to pass it on.Gotta love Internet
Radio!Scratch free 78's 24/7 what's not to love?He throws in ads, vintage,
too. good for a grin, Fords and Shell gas<g>!While we were talking about
life changes. What about the typewriter folks? With the net? I never learned
HOW to type, I have scene guyz use BOTH hands<g>!Hafta, nowadaze!
I hope to see a new magazine on the newsstands at, the airport or Penn
Station. "Racing EV's". You buy it and see the two page centerfold type ad
for Hy Torque Racing motors,Jim has hired 37 MORE guyz to meet demand!! same
for Cafe Electric Million amp Zillas. Now used by the US Navy in their
newest, fastest cruise ships! All the names that are household words have
gone national.We will have enough magazine filling stuff EVentually.NEDRA
goes in the 'zine biz?I mean look at all the car GO mags now? Car Craft,
sitting here.A listing, two pages of new strips opening in residental areas.
ELECTRIC only. Drawing crowds out for a fun day.Alota new created work, for
leftover Midas guyz?There will be plenty of work out there in my Perfect
World. You will ALWAYS need body shop guyz to streighten out bent electrics,
too?Tires, front alinment work, Custom shops, all that that is in place,
now.
You Tube is our best friend! With the Volt garbage you can watch the
Good EV stuff; guyz, like Forken Swift, common folks doing electrics.Of
course Killa Cycle gets alot of play-time, too.You can waste ALL day on You
Tube. 3 years ago there was NO You Tube at all. So send yur stuff in, put it
in front of the World! Beats the shit out of the printing press! YT just
links along. Interesting to read the "comments" stuff, too.YT goes all over

Depends on whether the motor has a built in fan. The ones I've seen
have had external blowers -- no fan built into the motor. But I
haven't seen an ADC up close either.

The point is, this is an opportunity to make EVs a commodity. Buying
parts at retail and doing conversions won't do it. GM is looking at
60,000 for the first year's production. Think about what that could do
for the price of battery packs.

This is a rather harsh comment. They certainly care about their
customers. They rely on them for future sales. The old Chinese curse
"may your wishes come true" comes to mind.
I wouldn't buy GM stock, but I'd like to be first in line for a Volt.
My first new car since 1964.

It does not depend on rotation as the fan blades are perpendicular to the
armature shaft.

That self discharge rate varies a lot by temp, doesn't it?

Hi Mark,
You only get a best of 300wh per mile? Seems pretty high consumption for a
914. Do you know how much your car weighs? Have you checked things like
alignment?
My 7000lb brick of a van gets 500wh/mile when lead-footing around the city,
and a little better @ 55mph.
Keep in mind, you can't really measure how much they were down by how much
"extra" you had to put back, because of overcharge. You ARE overcharging,
right? They definitely do self-discharge though. I'm planning on building
a small charge maintainer I can use to combat this.
35mile range, even at 400wh seems low, how many STM-5-180's are in there?
35 would be on par with about 15 STM's basing it on what I know about my
experience with Safts.
Seems like you could put on your hazard lights and just drive in the right
lane at 50mph and save enough to make it home, the surface streets,
especially without regen, are probably going to cost more than 50mph on the
highway.
This one case (flooded Ni-cd) where an EV could benefit from a solar panel!

Hi,
I have to leave my EV at the airport for a week Dec 1-8 for EVS-23 and
noticed that STM5-180's are listed as a 1% self discharge per day. Actually
I measured over 6 days when I went to NASA (have lunar rover schematics) for
Thanksgiving and it took 3 kWh to perk up again after being fully charged
for 16 batteries in my E-Porsche 3/.4kwh per mile = 7.5 mile loss. Since
the airport is 16 miles away with a 35 mile range at 60 mph I may not make
it home unless I take the backroads and maintain steady 40mph. (Can't get
all that EV stuff on my motorcycle).
Have a EVS-23 day,

Come on Bob. The 40 miles is on battery power. But when you are out of
battery you don't have to go home at 10 MPH with batteries merrily
boiling away. :-) Since it is a hybrid, what range would you design
the battery pack for? (Remember these LiON batteries are expensive.)

Can't you make it the same as the back end of the ICE crankshaft? Or
just cut off the end of a crankshaft and machine it to fit in your
adapter sleeve?

You are putting the hype before the horse.
General Motors did, in fact, design a significant EV from scratch,
intended to be an EV, with a number of revolutionary (for production
cars) features. Which no one else did, they all threw battery packs in
their existing made-for-gas models.
People are not stupid. They spotted that in a heartbeat. That's how GM
could earn the hype among urban carbuyers who generally abhor American
makes and love Toyota. If GM's entry had been a Pontiac Grand Am "EV",
the RAV4-EV would have looked good. It was precisely because they made
the EV1 insanely great, that it became an icon.

Anyone on this list could make a "money is no object" one-off EV that is
better than the EV1 when it isn't in the shop.
The real craft of automaking is in doing all that AND ALSO having it be
producible in mass quantity at reasonable cost and with the impeccable
reliability that's mandatory for the consumer automobile marketplace today.
The automobile market is possibly the toughest and most unforgiving
consumer market there is. Smart isn't enough.

Gifted with hindsight, the folks at GM certainly don't think they were
clever. Bob Stempel called it a serious mistake, says it set them back
10 years on the Volt program, and that it was never about money, the EV1
program wasn't a significant drain on GM's finances.
That's the power of being GM, they're huge, they can absorb the cost of
experimentation.

Or keep the cars going, so you gain priceless data about life-cycle
costs and reliability in production vehicles, that could improve
reliability of your next product. Like Stempel says, it set them back
10 years on the Chevy Volt.

I have a crankshaft and originally I was going to cut the end off to
make an adapter. This would work for a set screw adapter but not for
a taper lock adapter. There just isn't enough material there. The
end of the crank is only about 80mm in diameter.
I'm kind of wondering if I should just machine a whole new flywheel
with a taper lock bushing in the back instead of using the flywheel
that I have.

Hi,
I was curious and forgot to ask in the last email if the self discharge rate
varies with specific gravity. Presently my STM5-180's are up to the MIN line
at the end of charge and I was curious if the self discharge rate would
decrease if distilled water was added to the MAX line when the vehicle sits for
awhile. I assume the difference would be the precentage of water added and the
reduction of the same percentage of the electrolyte (potassium hydroxide) as a
linear relationship (about 10% of the 3% daily decay. So for the chemists out
there would adding 10% water decrease my self discharge to 2.7 % daily? (I
think the average specific gravity should be 1.20 and a min of 1.17).
P.S. for those recommending the TDI biodiesel beetle, it's an interference
engine, mine just lunched at 114k miles and cost me $4k to fix, with a good
timing belt. It would make a good conversion to an EV though. Consumer
Reports recommends the Prius instead (non-interference), reliability:
"Outstanding" (but I don't own one yet, maybe used one later.)
Have a renewable energy day,
Mark

But this is a series hybrid.
Battery sizing is totally different on series hybrids than battery EVs.
The idea is that the gas engine is there to power the car when you
outrange the battery pack, so dragging 120 miles of battery around 24x7
would be wasteful. Honestly, 40 is bigger than I expected, but I assume
they'll find a happy medium as this technology evolves. I'd peg it
around 20 miles, actually.

Content-Type: text/plain; charset="iso-8859-1"
I have not had a chance to get my Datsun truck out to where I can take it over
30 mph yet, but I've got a bit of a vibration issue I am curious about. I
spent a fair amount of time balancing the motor/flywheel/clutch assembly and
felt like I had that running very smooth before I installed it with the one
caveat being I had no way of knowing how many RPMs I was spinning it up to. I
used my 48 volt electric motorcycle pack and controller to spin it up and got
it going quite a bit faster then it would do on just 12 volts.
Now with everything mounted in the truck when I take off in 1st or 2nd gear
there is a bit of vibration I don't like. 3d takes off nice and smooth. I'm
wondering what the possible causes are.
One thing I am not sure about is the critcality of getting the
motor/transmission assembly lined up perfectly with the drive shaft. I really
only thought about the vertical alignment when I was putting it in, and did not
do any measuring, just eyeballed it. After I started looking into possible
sources of the vibration I measured to see how horizontilly centered I was
between the frame rails and noticed that the shaft at the brush end of my motor
is about 3/4 of an inch off of center. That does not seem severe to me since
it reflects the deflection along the entire length of the motor/tranny combo,
but I have no idea what kind of tolerences I'm dealing with.
It is also quite possible that the truck shook like crazy when it was an ICE
and I just did not notice because you kind of expect that from an ICE, but with
an electric I definitely notice. The other factor is that I did not include
any kind of rubber damping in any of my motor mounting, so perhaps that is all
I need.
My first concern is that I don't put it together in a way that ruins something,
and my second concern is that I want a nice quite smooth ride.
Any thoughts are appreciated.
thanks damon

Hello Jeremy,
My GE-11 has a 1.5 long by 1.375 diameter motor shaft that a SF size QD
bushing that 1.31 inches long. I install it in the conventional mounting
which the taper lock bushing flange is next to the motor bearing with a
clearance of about 1/32 inch, so it does not rub on the bearing surfaces
that do not rotated.
You do not have to have the taper lock bushing install in the reverse
mounting where the taper lock flange is against the fly wheel. I had a auto
machine shop cut a flange off a engine crank that fit my flywheel and they
install a taper bore from the back side. They then drill 3 large or 6 bolt
holes through the flange which are counter sink for installing the grade 8
allen head cap screws that pull the taper lock bushing from the front side.
My Warp 9 motor shaft which is suppose to be the same size as a ADC 9 is
longer then the 1.5 inch motor shaft on my GE, so even it a .5 inch short it
may still work.
Remember that the transmission pilot shaft may have to go through this
coupler and insert into the motor shaft. The Electro Auto design there
coupler a lot longer, so the transmission bushing is on the end of this
coupler instead in the motor shaft. This requires a thicker adapter plate
to push back the transmission further or pushes the motor ahead.

Hi Damon,
I am not an expert when it comes to clutches and
alignment, but when mounting motors to pumps or
gearboxes, alignment tolerances are on the order of
.001 inch per inch for eccentricity and
perpendicularity.

I would try to isolate where the vibration is coming from. Do you get
it with the clutch in? Trans in neutral? With a wheel jacked up?
Less vibration in 3rd would indicate perhaps that the vibration
increases with increasing RPM. That would seem to exclude the
driveline. The output of the trans should be parallel to, but not in
line with, the input of the differential.

Hello Damon,
If you are using a taper lock bushing, the taper lock has a split so it is a
bit larger than the motor shaft and the set screws tighten this bushing down
over the shaft. The difference on side of this bushing opposite the split,
I have found there may be a difference of 0.002 to 0.0001 out of center
line.
So when I had a machinist with one of those computerize milling machines,
center the bushing for me. He install this bushing on a short piece of
shaft that was the same size of my motor shaft and he check it by spin
balancing. He the rotated the bushing one turn of the bolt hole and check
again. He repeat this until the position of the taper lock had the best
center line which was something between 0.001 and 0.0001 inch.
Also if the motor shaft had a coupler on it that made it rough, this could
throw the balance off some. I had to remove the rotor and had it resize,
balance and than install the coupler on it and check the balance again.
Install the flywheel and check, then the pressure plate and clutch and check
again. They then mark the flywheel in relation ship to the pressure plate
to the relation ship to coupler, so I can install it in the same
relationship.
Also there is another thing that may through off the whole thing. If the
flywheel is a external balance one, which means it is use to balance a
engine. It is prefer to use a internal balance flywheel that is use for
balance engines.
If you think your flywheel is a external balance type, then you may have to
have it re balance. If you have that done, it is best to pull off the
starter ring gear and have the flange edge that held on the ring gear thin
down to the same thickness of the center section of the flywheel.
