Cam seal replacement
Written by tom43004 on 10/16/2010 at 12:12 am

I did the cam seals a couple of years ago with nothing more than a toolbox and
an exploded diagram from the service manual. It wasn't too bad. I've had ZERO
oil leakage in two years since.

Go ahead and do it. I can share (hundreds of) pictures if you want to see the
steps involved. I did it while doing some other stuff too like replacing
brakes, a wiring harness, water pump, reconditioning the muffler, etc.
Basically I took mine down to the frame.

I pulled the heads to do mine, and wouldn't do it any other way. You'll have a
real appreciation for how well these machines are designed after you see what's
under the covers.

But... it got done and it doesn't leak. Probably took me more time to do that
then a pro would take removing the heads.

(IMO) if the plugs were shallow enough, it would be a hell of a lot easier to
install them than cam plugs. (Just my thoughts).

budget a day for each you may be pleasantly surprised. A torque wrench should
be available, particularly for working on the cylinder heads. That's the most
exotic tool you should need.

doesn't want to go there. Some Tupperware, the air box, carburetors, engine
shroud and some oil and coolant plumbing need to be removed. Fairly
straightforward wrenching with the odd bit of fun. (How did they pour the
engine into the shroud?) As long as you don't drop parts inside the head you
shouldn't need to, um, express yourself verbally. Do make sure that you have
all of the O-rings, seals, gasket and fiddly bits before starting.

brief look at the PC Service Manual doesn't seem to show any challenges. Just
another gasket to scrape. (The Wing requires a Special Service Tool to remove
the clutch pack. It can be made in an hour or so from a 12-point socket using a
Dremel and files.) May as well do it while you have the oil drained.
