That is a real shame, someone should call DFCS on general principal.


Please tell me you dont really ride a motorcycle by redlining it and 
then slowling releasing the clutch?


Steering bolt is correct. Also the shifter can be rebuild along with 
bushings to make it nicer.


Why in gods name would anyone put those tires on?

What is it with people who don't fix cars with that kind of leak,
anyway?  The smell of hot coolant makes me sick to my stomach in
seconds.

This is an actual exchange between me and the seller of a car I
test-drove not too long ago:

ME: Wow, that coolant smell sure is strong.
OWNER: Oh, is that what that is?  Smells like maple syrup to me.
ME: Did you recently change out the heater core and some of it
spilled, or something like that?
OWNER: Nah, it's always smelled like that.  My kids love it.  They
say, Daddy, can we ride in the car that smells like pancakes?

Re: [MBZ] Stick 240D adventures

2011-08-24 Thread Dieselhead

Probably a moot point if you ran away:
The steering slop at 20-30 years can be in the coupling between the 
steering gear and the steering shaft.  It has rubber reinforced with 
cord to take up the shock.  The rubber disintegrates.




Went to see a '78 240D 4-speed (W123) advertised on CL.  Pretty good
cosmetic shape but some weird things compared to other 123s I've
driven.  Steering was extremely loose, is this the infamous
left-hand-threaded steering box bolt that needs to be tightened?  The
seats were an odd vinyl-cloth mix, sides Tex as usual, but the fabric
in the center was not the usual Euro scratchy tweed but a smooth
satiny material with a sort of herringbone pattern.

The clutch and master cylinder were new, according to the seller, and
the clutch seemed to have about half an inch of engagement range,
right at the top of the pedal travel.  The shifter had none of that
notchy feel that I associate with German cars, but was really loose
and sloppy---the proverbial broomstick in a barrel of rocks.  Combined
with the feeling of barely adequate torque and no power, it was more
than a little like driving a VW microbus.

Seller had some weird ideas he'd picked up from the 240D nuts
online.  For example, the car was riding on 205/70R14s on the stock
wheels (for better ground clearance---it's two inches higher this
way!), and he said that although he was afraid to try it everyone
says you should burn the clutch when starting out on a 240D... by
which he meant that on every takeoff you should floor the accelerator,
then at redline gradually let out the clutch to accelerate, slipping
it all the way like a motorcycle.

Climate control was wonky, too, despite being the famously reliable
manual 240D system!  The blower fan barely worked, A/C didn't (later
found out the belt was gone), there was a strong smell of coolant at
all times, and the temperature sliders didn't do anything---there was
full heat all the time.  Seller thought that was normal.  You control
the heat with these! (indicating the twist open/shut feature of the
side dash vents).  (Never mind that there was hot air coming out the
foot vents regardless.)

All in all rather disappointing.

Of course not---I was referring to the general idea that it's OK to
slip a wet clutch when needed whereas, as Philip said,  one ought to
slip a dry one as little as possible.  I was taught to pull away from
a stop on a bike by revving up about 1/3 to 1/2 into the rev range,
then gradually releasing the clutch and modulating the throttle as you
gain speed, in order to avoid the sudden throttle application at low
speeds that often will make a cold carbureted engine stumble or even
die.

Just the opposite of what I do.  I give it fuel, and then drop the

Exactly how I was taught, on modestly powered small Japanese cars in
the mid-'80s.  Kids these days (if they even learn how to drive stick)
don't learn that skill; nor, I've noticed, do they learn when to
downshift: they're used to cars with so much available power across
the rev range that you can just lug the engine as you decelerate and
then take off again (say, when approaching a stop light which turns
green just before you get there) in the same gear.

Dunno, might be right for a 116.  Jaime ought to know what was stock,
although it'll be one of the old-style size codes with a fixed aspect

IIRC, the 'right' tires on my '79 SD were either 185R14 or 195R14. Tires were 
much taller back then.I believe the original aspect ratio was 83. 185/83R14 
would be about 26.1 diameter. 205/70R14 would be 25.3, you're still looking at 
3% odometer error.

 figured defective heat control valve at best, leaky heater
 core at worst. (Wherever either of those are on a W123 240D).

The control valves are on the firewall, right next to the heater
core pipes.  A solid wire in a sheath cable connects from the
valve to the knob.  So utterly simple I would be very worried
about the rest of the car if that was left un-fixed.

The heater cores are _way_ down in under the dash.
The center console and the whole dash have to come out.
However, it's _much_ more likely that there is a hose-to-pipe
leak at the firewall and the coolant is running into the car
that way.

The shifter is needing bushings, when I first got my '85 190D I couldn't get it 
into reverse reliably because of them. A couple times I had to push the car out 
of parking spaces...

The clutch issue is EXACTLY like my '78 240D. The later clutch rod is the only 
one available and is the wrong length. I didn't know that and threw the old one 
away accidentally. I'm going to try to modify a newer one to work as I haven't

Went to see a '78 240D 4-speed (W123) advertised on CL.  Pretty good
cosmetic shape but some weird things compared to other 123s I've
driven.  Steering was extremely loose, is this the infamous
left-hand-threaded steering box bolt that needs to be tightened?  The
seats were an odd vinyl-cloth mix, sides Tex as usual, but the fabric
in the center was not the usual Euro scratchy tweed but a smooth
satiny material with a sort of herringbone pattern.

The clutch and master cylinder were new, according to the seller, and
the clutch seemed to have about half an inch of engagement range,
right at the top of the pedal travel.  The shifter had none of that
notchy feel that I associate with German cars, but was really loose
and sloppy---the proverbial broomstick in a barrel of rocks.  Combined
with the feeling of barely adequate torque and no power, it was more
than a little like driving a VW microbus.

Seller had some weird ideas he'd picked up from the 240D nuts
online.  For example, the car was riding on 205/70R14s on the stock
wheels (for better ground clearance---it's two inches higher this
way!), and he said that although he was afraid to try it everyone
says you should burn the clutch when starting out on a 240D... by
which he meant that on every takeoff you should floor the accelerator,
then at redline gradually let out the clutch to accelerate, slipping
it all the way like a motorcycle.

Climate control was wonky, too, despite being the famously reliable
manual 240D system!  The blower fan barely worked, A/C didn't (later
found out the belt was gone), there was a strong smell of coolant at
all times, and the temperature sliders didn't do anything---there was
full heat all the time.  Seller thought that was normal.  You control
the heat with these! (indicating the twist open/shut feature of the
side dash vents).  (Never mind that there was hot air coming out the
foot vents regardless.)

All in all rather disappointing.

My '78 pump was not right.  I put the pump from an 81 in and it
made a very big improvement.

 For example, the car was riding on 205/70R14s on the
 stock wheels

That will make it accelerate slower!

Eeek!!  Slip is bad.  Use as little as possible, and only as
much as absolutely necessary.

 The blower fan barely worked, A/C didn't.

Heh.  The '78 has the old, big York compressor.  That's my only
one that still hold pressure.  

I would add it as a parts car - but only it it was $400.

 This is the size that's on my recently acquired 300SD I
 take it these are not the right tires... Too bad because they
 look almost brand new... :-(

They fit fine, but it's noticeably taller than original.  On a
low power 240 it will make it even slower.

What's the rolling diameter of the original on a 240d?

I just did a search. Looks like 175SR14, which would have about the same 
diameter as a 207/70R14.


What's wrong with 205/70R14 again?

 Dunno, might be right for a 116.  Jaime ought to know what was stock,
 although it'll be one of the old-style size codes with a fixed aspect
 ratio (P185R14 or some such).

*walks out to the '78 to check*

175SR14 is the recommended size.

That is has aspect ratio of 82, according to this site:
http://www.barrystiretech.com/tiresizing.html

Therefore it's unloaded circumference is 2018.79 mm.

Compared to a 205/70R14 which has an unloaded circumference of
2018.79 mm.

Hah!  So much for what I though I knew!!  Exactly the same!

Now, that's not a rolling circumference, but that can vary from
tire to tire.

You might check with the Classic Center for part number and purchase
from the dealer?
I did that after the dealer got me the wrong one, plus mine is a euro '84.

 Yeah, but combined with the strong hot-coolant smell?  I figured
 defective heat control valve at best, leaky heater core at worst.
 (Wherever either of those are on a W123 240D).

 The heater valve should be on the engine side of the firewall.
 Leaks somewhat unlikely to propagate into the cabin.


What is it with people who don't fix cars with that kind of leak,
anyway?  The smell of hot coolant makes me sick to my stomach in
seconds.

This is an actual exchange between me and the seller of a car I
test-drove not too long ago:

ME: Wow, that coolant smell sure is strong.
OWNER: Oh, is that what that is?  Smells like maple syrup to me.
ME: Did you recently change out the heater core and some of it
spilled, or something like that?
OWNER: Nah, it's always smelled like that.  My kids love it.  They
say, Daddy, can we ride in the car that smells like pancakes?

Here's a nice tire calculator.  It even includes some xxxSR14
tires.  But not a 175...
