It's a complete top end including everything clear up to cam cover and cam
cover bolts.....minus the chain...SIGH! It's all assembled too. Well, a girls
gotta go what a girls gotta do. It all looks real good though and all of the
cam cover bolts are in good shape too. They said it came off of a good running
bike just one week prior. For $36.00 off of e-bay, not bad. HotrodMamma.

How much of the head is assembled ? Did you get with cams and all ?

I was afraid of that. We'll, I'll just have to disassemble the top
end to get that chain on. Thanks Dennis.

NO. There is no master link on an endless chain (loop or
whatever you want to call it) To remove a cam chain from a Honda the crankshaft
must be removed. I have written a detailed set of instructions for this job.

No choice...The guy sold the one that was on that top
end...is there a master link? That was one thing I was going to ask you.

You are going to use the chain on your bike ? It's
a loop chain and held in with the crankshaft.

Thanks for the info Dennis. I'll be putting
my "new" top end on next week. I bought it minus the chain so I needed to know
this. I agree on using a torque wrench too. I've made that mistake, I.E.
breaking a bolt and it SUCKS. I love my bike but these Japanese bolts just
aren't as strong as good ol' American steel. Paul...don't fret too much, just
pay close attention, do what Dennis says and get 'er done! If you have any
doubts take photos as you go. If you want to see what I've done on my
Nighthawks or Harley go to the Photobucket site and type in "HotrodMamma". I'm
going to cut some gaskets for my Nighthawk soon and will post a how-to. The cam
cover gaskets are hard to get and expensive. I can make one for $4.00 plus my
time. I'm going to keep a pattern for later too. HotrodMamma.

Get a grip. Not all parts are updated at the
same time. Without my asking a counter person to check, I recall that there is
only one update spring and a couple of updates to the tensioner assy. You do or
do not have the OEM manual ? Not Clymers book of the dead or some such. Please
take the time to read the common service manual. All specific manuals are based
on the viewer having done this. Cam sprockets are marked with lines that are to
be in line with the head surface. Study the manual before disassembly and take
pix if needed. Do not play switch with any parts. Replace each part (tappet
adjusters, cam followers, cam journal caps, etc) in the EXACT place it came
from. Lay parts out in an orderly fashion in a place that will not be disturbed
by kids or pets. Do not introduce any new variables by a careless assembly. A
light dab of grease on the cam lobes willl do,a drop or two of oil on each
journal. Fill anti-foam chambers with oil. Before replacing the head cover,
remove the plugs (should be out already) and spin the engine over with the
starter. Repeat in short bursts untill oil is seen flowing.
You want tips ? Here's one. Some tech's have
called me over because the cam chain isn't long enough... duh. It did fit. What
happens is that it "drops" a link under the crankshaft. You will need to rotate
the crank a bit while holding the chain up and it will straighten out.
The possibility exists that you are a he-man.
Use a torque wrench on ALL fasteners. It's way too easy to strip the 6mm bolts
that used throughout. Start each one with fingers to make sure you don't strip
any. Specs are in the front section on the manual.
Service bulletins from that time are all on
paper. Where ours got to after all these years may be a chore to locate. Rob
may have taken them when he left. Just stop fretting about all this and be glad
you can get parts. The original (questionable) parts have disappeared. ONLY
updated parts are available. Honda bought back those many years ago.
I lied. I've only got 37 years with Honda. 42
total. First with Suzuki and Yamaha.
Wanna' "degree in" the cams ? Makes 'em fly.
Advanced procedure, but big performance boost.

Thanks Dennis.
Do you suspect the -010 tensioner bracket had
the modifications that
"improved" the tensioner from the original?
Do you now of a technical service bulletin
addressing the repair of
the failure. I think this may be valuable to
those of us with less
historical experience with the NH tensioner (42
years at Honda - wow
that's more knowledge than i can imagine). I
tried to find a TSB on
the web but no luck.
Well i found a NOS spring (14514-ME5-010) at a
Honda shop in Ohio - it
should be here in a few days - at that time
i'll remove the tensioner
and measure spring force between the two
springs (maybe that will
prove hopefull if there is a large difference).
It doesn't sound too difficult when reading the
OEM manual but a bet
they leave a lot of the little tricks out. I
guess just think
everything well through before you do it. I
think I'll take a picture
of the cam sprocket allignment marks (with #1
at TDC compression)
before the removal to ensure it is reset the
same after intall (that
part makes me a bit nervous!). The OEM manual
was a bit unclear of
what cam mark alligns with what part of the
head surface. And I won't
swap positions on any components.
Thanks,
Paul
