Camchain Tensioner and Cam Chain Question

[Guest]

2 questions for you guys. I have a 77/78 GS550 and need to replace the gasket on the camchain tensioner.

1. I can take off-adjust-install the tensioner without messing up the camchain position correct?

2. With my 77/78 engine, does anyone know if my engine has a chain slipper block for the camchain? My Clymer manual only says “on models equipped with a chain slipper block”, but doesn’t list which models have one.

If someone knows the answer, you’d be saving me wrenching time and money on buying new cylinder cover gasket.

1. No problem.

2. No clue.

While you have your tensiner out, why not change the seals inside it, too?

Then, when you re-install it, be sure to do it correctly.
1. Loosen the locknut and set screw.
2. While turning large knob, push plunger in completely.
3. Turn set screw to hold plunger in place.
4. Install tensioner in cylinder block (using new gasket).
5. Turn set screw to release plunger.
6. Turn set screw back IN until it touches plunger.
7. Turn set screw OUT 1/4 to 1/2 turn, use lock nut to hold it in this position.

Quite often, the first part of #7 is ignored. Guys will read "turn the screw in ... lock it in place" without noticing that it needs to be out just a bit, so the tensioner is free to take up slack as necessary.

Do yourself a favor and go crazy by removing camcover and check...and why not check valve clearances - most likely they need some attention.
