Swingarm lateral movement.

Post by bubbaad » Tue Apr 28, 2020 5:19 pm

Fitting a yzf750 swingarm that was on another TRX and there is lateral movement, about 10mm when it's bolted onto the subframe which it fits into perfectly. Am I missing something obvious here ? Just doesn't seem right. Any help appreciated thanks.

The needle bearings were never taken out. The movement is side to side along the length of the pivot.

Sounds like you are missing end caps on the swing arm. Still, 10 mm is a lot... :shock:

Seem to remember spacers inside the end caps maybe. Think I looked at exploded diagrams at local bike shop n ordered them. Cheers, Andy.

End caps are on, swingarm fits into the subframe as it should. I must be missing something obvious......

Just a note in case you are looking at the parts manual or online parts finder...
The part number for the swing arm pivot shaft is 3GM-22141-01.
Both the manual and the online parts finder show the rear axle part number 3BN-25381-00 instead.
Although they share the same pivot shaft, the parts list for the YZF swingarm shows two shims (3XV-22127-00, #4 on the diagram) that are not part of the TRX setup, so maybe these are the parts you are looking for.

A bit late but I do remember the YZF swingarm had spacers fitted were the original TRX one hadn't. They were located under the end caps if I recall correctly.
