Need help adjusting spur gear
 

I got my son a Savage SS for xmas and were having a problem. We already melted 2 spur gears durning the engine break-in.

Its next to impossible to look and make sure the gears are the right amount apart. What's the trick to getting this right?!?!


Also, whats the trick to keep the stock shocks from leaking oil?? All but 2 of the shocks are leaking oil all over the place when they are compressed.

shocks need to be bled I think..check the instructions for that

as far as gear mesh,
1. loosen the motor mount (dont' take it out, loosen the screws),

2. place a piece of paper btw the clutch bell and spur,

3. squeeze the spur and clutchbell together (which would mean move the engine to the spur),

4. tighten the screws down.

5.rotate the spur to take the paper out, and it should have a "steps" look to them (from being btw the gears). and you gear mesh should be set.

To check, hold the cluthcbell with your thumb and try to move the spur gear, there should be jsut a "tick" of movement (you shold only be able to move it really slightly).

one last thing: THREAD LOCK the motor mount screws!! to do this, take one out, dab it with blue threadlock, screw it back in, repeat with the other screws one at a time, and do in in a criss-cross pattern (upper left, then lower right, then lower left, then upper right). This keeps the mesh and evens out the pressure of you screwing the screws in, keeps things "square".

Hope this helps

Thanks for all the info. I can't wait to get this thing going!!!

Your slipper clutch is too loose.

Tighten the slipper nut until the spring is fully compressed
then leave it there like that.

Some ppl might *overtighten* the nut until the spring is deformed
and cannot do its job. You need a new spring & nut if so.

Loosen the engine then push the 2 gears together.
The gears must engage but not jam up too close together.
You can try a piece of paper between them, but by
eye & feel is usually better.


Shocks shouldn't leak enough to make a mess... although after
a lot of running yes the oil level does drop a little.

Have you built them correctly?

Did you manage to damage the o-ring seals during assembly?
(eg putting the shaft thread thru can rip the seal/s)

Might need to rebuild them using new o-rings.

I didn't check it, becuase it came built from the factory. Now that I took a look at it, the nut was very loose. My fault for not checking!

I built them according to the instructions that came with the Savage. I screwed the caps down until they just made contact with the O-rings. I checked out the shocks again and it looks like the problem came from the manufacturing of the shock itself. There is a lthin ine of plastic that runs perpendicular to the threads (where the cap screws on), which I think may be preventing a good seal.
