Fitting a new wheel
02/10/22 at 14:50:14

I've got a wheel from a EN500 that I'm trying to fit to my beast.
I've previously adapted marauder forks to the Beast and it has a larger axle.
I've gotten new bearings that fit the wheel and the axle.
Also a larger spacer that fits the axle and cut it to match the original spacer length.
But it's still longer than the space between the bearing lands by 2mm.

Should I cut it to match the bearing lands or leave it as it is?

I believe the spacer should closely match the distance between the seated bearings. If you don't - then the bearings will be 1mm from being fully seated on both sides.....or some portion of 2mm on either side.

Not being fully seated may not be a problem though - as a motorcycle wheel receives little or no load from the side, and most bearings are in pretty tight and aren't likely to move around once things are bolted together.

I never have ever measured the spacer length vs. the bearing land separation.....they may all have an intentional clearance to allow the bearings to move as needed to match the spacer length.

I believe the worst thing you could do is make the spacer too short - then when you tighten the axle the bearings would be squeezed and a big sideways load would be imposed on the bearings.

The only thing I say is And you know it already is If you crush bearings That is worser than leaving them a little loose.

Surprisingly, EN500 spoked wheel is not the same as an EN500 alloy wheel. For the spoked wheel I had to use spacers to align the disc and caliper. I had to remove these spacers to center the alloy wheel.

When I was in high school I worked in a mower shop after school.

When we put new ball bearings in a mower spindle they were very much like the wheel bearings in a motorcycle - with an axle and center spacer exactly like the motorcycle hub. When we put the new bearings in we would get them started in the housing, then put it all together and tighten the axle bolt to pull the bearings into the hub - and the spindle would be a bit stiff to turn. Then we would wack the spindle with a hammer, and everything turned smoothly - I now realize what was happening is that by tightening the center bolt we were pulling the bearing into the housing....but the bearings were not fully seated and they were in a bit of a bind - wacking the center spindle would shock the bearings and allow them to slide into the proper spacing.

Not in when I was 17.....I was fixing the mower the way I was instructed to. It wasn't a two handed sledge hammer affair - just hold the spindle in your left hand and hit the bottom of the spindle with the hammer in your right hand. I worked at that place for about 3 years.....we never had one fail....just worn out bearings as folks would not grease them often enough.

The shaft was about about 1" diameter, and we would hit the bottom of the spindle where the big flat area was that the mower blade would mount. The wack we gave it was very likely no worse than the wack it would get when you mow over something like a baseball or stone.

So, Dave admits he Brinelled bearings,just not Wittingly.
I did too. Pedalling a ten speed through a high speed corner when the pedal hits the asphalt and the bike gets airborne, yeah, that fits..
The internet cruising your post led to was very informative. Thanks!
