Swingarm pivot bolt torque values ???

[PedroTQ]

G'day to All,

Just going over my 88 GL-1500 that I recently bought and changing all the lubricants etc.

Washed the swingarm bearings, applied new Lithium grease (low on Moly 60) but I am not sure how far to torque the pivot bolts up to ??

Can anyone help me please

Regards, Peter.

72 ft. lbs on the right side first, then 14 ft. lbs on the left. Lock nut for the left side is 65 ft. lbs.

Make sure the pivot portion of stud engages inside of bearing while installing, I sometimes put a chamfer on outer edge of stud to aid installation. The bearing has to ride on the stud.

Thank you very much "ct1500" for that, I just nipped them up until now, I can do it right.

Best regards, Peter.

why such a great difference in right side and left side torque?

[ct1500]

To set bearing preload only requires one side to set the value. Right side is taken up tight which is why there is no locknut. Left side is then torqued and value setting maintained with locknut.

O. Ok thanks. I did not know that. I can understand that on rear wheel axel but swing arm is not conn ected to other side

[ct1500]

It is connected to the other side via the swingarm tube which holds the bearings. If you tighten left side to 14 lbs the same 14 will be transferred to the right against the pivot stop.

Same principle as head bearings where torque on the top nut is for both upper and lower bearings.

If one side of swingarm did not have a positive centering location within the frame which the right side does, when reassembling it is possible for the swingarm to be out left-right causing a dog tracking situation. Dog tracking on a vehicle is when rear wheels are not in line with fronts.

PLEASE HELP... I changed my u=joint. Torqued to specs. All is good. No vibrations. Running true. But... sometimes when I back of the throttle. I get a (slight) u=joint clang. I put it on the center stand. Gained access on the left side. Tightened less than a 1/2 turn on the 14 ftlb side. torqued retainer ring (pinch nut) to 74. Still have the clang. The bearings were centered when I put the both sides on. ANY THOUGHTS???
