VN 900Custom Triple Tree Question

Stepson has one and we are removing the raked triple trees he had on and
putting the stock ones back on. The raked ones were crappy they leaked fork
oil all the time.

Anyways the question I have is the lower tree goes on and at the top you
have the bearing an oil seal then a dust cover and then the notched nuts
that tighten the lower tree up. My question is the dust cover seems to have
an 1/8th to a 1/4 inch play up and down , is this normal.

Yep. Not sure if you'll definitely get an answer in here but there are much more 900 drivers in here than the other forum. Good luck to you.

That's what I'm hoping, shouldn't be too hard for someone to check on their 900.

Shoot a picture of what you are talking about and post it back up here.

I wandered out to take a look at the stem bearing on my VN900.

The "dust cover" does not flop around on my bike...see arrow in the image.

When re-assembling the triple tree, the shop manual says to leave the lower fork clamp bolts loose until the correct torque is obtained on the stem bearing - so the fork clamps do not interfere with the sliding of the upper tree as it slides downward as you torque the stem bearing nut.

If you look at the manual for the 900 custom on page 14-9 they show a diagram and it looks like there is a gap there. I belive they refer to it as a stem cap.

I don't know what to say to ya - on my Custom the Stem Cap (C) is tight under the stem nut (D). I'm looking at page 14-9 of the manual. If you are following the reassembly procedure (including settling the bearings at 40 ft-lb torque), then loosing off the stem nut, and re-torquing to 43 INCH-POUNDS - then I don't know what to say.

Without me disassembling my triple-tree (nope), I'd put it all together according to the manual, and then check for play in the head bearings (see manual page 2-36 to 2-37).

The black plastic cap is not load bearing. The steering stem nut has an inner shoulder that the plastic cap fits around.

-IF- the nut is factory and has the correct depth shoulder the cap should not move up and down. -IF- the nut is factory and the plastic cap is moving up and down you should be able to jack your front end off the ground and also get 1/4" play up/down in your entire front end. This means you have assembled it wrong.

-IF- the steering stem nut is NOT factory and is leftover from the other triple tree then all bets are off and you are on your own.

Attachment 229792

If you look mat page 14.8 in the manual the second diagram shows what appears to be a gap between E and the dust cover. I will check for up and down on the forks and take it apart again. Did you check the cover on your bike? The two nuts are factory items C and E in the diagram on page 14-8.

Thanks appreciate the help.
