Title: rear axle torque
Post by: fastgpz900 on October 01, 2016, 07:39:36 PM
Ok, need some help here. I just got an FJ1200, remove the rear wheel to clean it up, put it back try to torque the axle to 100lf-lb as specified. The wheel can barely turn  :dash2:and make noise :scratch_one-s_head:, loosen the nut a bit and everything turns fine. :nea: What am I missing. I am prbably at 80lf-lb, I am worried that the axle is not torqued enough.

I would verify that the following spacers are in place. #33, #2, #15 and #32 in the drawing that is the attached link.

When changing wheel bearings, I have heard that the spacer #15 is critical and can not be left out. Bad things can happen.

I torque my rear axle to 110Ftlbs and then back it off a bit to line up the hole for the cotter pin.

all spacers are there, but the #2 is a bit loose or better said has play. The previous owner changed the bearing so I wonder if he did not seat the bearing far enough to really sit the bearing on the spacer. I have the feeling I am putting side load on the bearings, like the cage and spacers are not making a really tight compression.

all good now,  :good2: I took everything apart and one bearing was not fully seated so there was a gap on spacer #2  :negative: drove the bearing to seat and now torqued at 100 ft-lb and it is turning freely. :yahoo:

good to go for tomorrow's fall ride, yes the leaves are turning red in my neck of the wood.
