Re: [ST] Re: Sprint 2002 Rear Bearing Failure - the story continues

[Dan Wallander <newsgroup@xxxxxxxxxxxx>]

The recall was for VIN# 132693 THROUGH 161257 and is for the right hand 
rear wheel bearing only (the one closest to the wheel).  This applies to 
all single sided swing arm Triumph within the VIN# series.  The part 
number for the new bearing is T3800220 according to the original 
service/recall bulletin. 

I don't think there was any change in the design of the rear hub.  Most 
likely what happened was a change in manufacture of the bearing from 
their supplier or in the supplier for the bearing itself.  Quality 
control at the bearing factory may have taken a dump and a bunch of bad 
bearings went out the door.

the second bearing failure may not have been manufacturer related, but 
installer related.  Did they install the bearing correctly, did they use 
the correct and  enough grease in the bearing, did they grease the 
bearing at all?  The seals on the bearing are reused and if damaged 
during removal but still used in reassembly could allow dirt into the 
bearing.  Damage to the hub can result from not being careful during 
bearing removal and replacement also.

I know this doesn't answer all your questions, but If the replacement 
was done correctly, it should be safe.
