Working on a 72 T100R and decided to replace the original bearings with sealed bearings. Question is, on the rear in particular, do I need to put all the shims and grease retainers that held the grease in the old bearings back in with the new sealed bearings? Not sure if they play any part in keeping the central distance piece spaced correctly or if they're simply to retain grease.

Thanks
Ric

Fair enough question Ric,

The answer is no. The grease retainers become redundant when sealed bearing are installed. As you seem to understand, some external spacers may still be required to centre the hub. HTH, RR

Mr.Pete

Leave everything in on the drive-side.This locates you spacer tube central.Leaving the inner grease cover on the timing side will help this location,but you might get by without it (could be harder to fit the axle through).
Leave out the outer grease cover on the timing side.

I did my bearings and kept it all in there. Leave it alone or should I pull the timimg side out?

Thanks,

Thanks for the replies guys. I was leaning toward putting in all back in due to the spacing issues and you guys confirmed it. Looks like it's going to be fun getting the center distance piece back in place...

PLEASE mke sure you ease off one side of the sealed plastic to check there's enough grease inside! Depends on the bearing but I've seen only a gram or two sometimes inside(& it was clear grease)?You don't want it packed tight but enough to last a year or so...
When I was doing motocross,those 'sealed' wheel bearings would sometime only last a month... And if your.ve ever had one fail 'on the road' it could be serious(ask how I found that out)!! Cheers...

I have no personal experience, but have heard this from many sources. I note also that many bearings have a pressed metal seal that would not lend itself to peeping inside.

If the manufacturer does not supply sufficient grease, that's incompetence, and they ought to be all sacked!! RR
