Title: Rear hub
Post by Cavie on 03/25/12 at 18:58:41

I seemd to have some play in the rear hub. What's the expected milage on the rubber shock absorbers in the hub. I have 18,000. Play is front to back and side to side. Is this normal?

Some play to be expected.

How much?

If you are talking side to side,......same as if you were to loosen the nut on the wheel bearing of a trailer, or the front wheel of a car,.......I would suggest you have bad rear wheel bearings,......even tho thats not likely.

The only play I would consider normal would be forwards and backwards.

Thats the way I see it. I suspect the front to rear is normal. It's the side to side that has me concerned. >:(

Belt pulley is supported by a single large radial clearance large ball bearing that is firmly trapped "Radially Only" between steel bushings internal to the wheel and axle.

The rear pulley is separate by design, so it can roll and rock separate from the wheel controlled only by the rubber shock bushings. The more wear on those rubber bushings, the more it can move.

In other words, side to side tilt is OK. Don't sweat it -- it is normal.

Some people replace their rubber bits along the way, others don't.

:D

Some people try to "track" their belts according to the way the rear pulley is when the bike is jacked up, others realise it tracks from one side to the other when decelerating and accelerating (tilt changes according to the load).

Other people just use a 4 1/2" grinder to bevel the sides of the teeth on the belt so it doesn't squeak no matter what it is doing.

That's the why I see I but wanted confermation from someone in the know. Hearing a little whine from the left rear. Assuming it to be normal belt noise. My VOL has a driveshaft. The movement seemednormal to me based on what is saw how it was designed it had to have movement in all directions.

Last time I had the rear tire replaced I sliced up the old tube & used bits to shim up the rubbers in the hub.

My rear wheel with rubber inserts has 85,000 miles on it and never been replaced.
