Careful with Jackshft Bearings

[S pump]

I have mine apart right now and have a couple questions. How do you get the jackshaft brg lock ring tight?? prt# 18 & 19. I have held the nut with a spanner wrench and tried turning the secodary to tighten but the locking threads just spin on shaft. It only goes so far finger tight and I cant get anymore on it. If I hold the lock ring the shaft just tuns inside.

Second is on the chaincase side. There is a washer under the top gear nut and it is cupped. prt#53 Which direction does the cup ( face. cup to motor ( or to brake )?

As for the side to side play in secondary clutch I had play before I started and hope it is there after.

Be sure that the threaded sleeve is in the correct depth and direstion on the shaft (See the link in the first post) it goes in a taper in the bearing. Once it is seated correctly, you use the secondadary to tighten it up.

You need something like a spanner wrench to hold the locking ring in place as you turn the secondary. The nut does not have to be extremely tight. Just tight enough so that it will not move around and work loose.

I have seen posts where guys use vise grips to pipe wrenches to hold that nut. But a spanner wrench that is a close fit works best. I have several spanner wrenches from the dirt bikes and other shock wrenches, etc. I even have a couple I made up for special applications (e.g. long handled ones).

It is a good idea to check the nut for tightness after a few miles down the road, too. if it worked loose, you did not tighten it enough.

I made a little tool out of 1/8" thick x 1/2" wide steel. I ground the end down just wide enough to fit in the little slot in the collar (around 1/4" wide), then carefully clamped it to the jackshaft on the secondary end. That stopped the collar from turning when I tightened the nut. Just set the parking brake to stop the jackshaft from turning.
