Mag Wheel: No spacer between bearings

🇮🇹💦 Of the Loin /

Is this bad?

I forgot to put a spacer in before I put the bearing retaining compound in (the bearing seats are a little out of spec, but there is a mag lip they rest on).

Do I need that spacer in there? They are sealed bearings

Re: Mag Wheel: No spacer between bearings

They will blow out sooner than later. I don’t recommend it.

Re: Mag Wheel: No spacer between bearings

yeah, not good maitland.

Re: Mag Wheel: No spacer between bearings

Use bearing retainer with a shim, not alone.

Yeah dude, no beuno. The spacer translates the sideload and keeps from your outer spacer bowing the inner race inward.

Yeah I just didn't want to remove one of these :/

Also FYI it's too small a clearance for any shim. It's within the spec of the bearing retainer tho

Ok fuck that green compound is serious about holding on

Re: Mag Wheel: No spacer between bearings

It might come loose at about 350° F .

That's a bit less than half the melting point of magnesium alloy .

The spec sheet says 250, but I dialed my reflow hot air gun up to 400 and used a deadblow hammer and a punch.

Bearing came out but it's toast, that retaining compound had only been on about 25 hrs and it wasn't letting go.

Would reccomend for gaps of 0.05-0.25mm

Re: Mag Wheel: No spacer between bearings

I’ve see it done and it was on a ripper bike

The trick is to use a standard moped threaded axle and put the double nuts locked up against the inner races. Then it won’t pinch and it will be fine.

So you would need to put one bearing in, then the axle, then the other bearing? That would work, unless you had closed end drop outs, because you wouldn't be able to remove the axle to install the wheel.

Re: Mag Wheel: No spacer between bearings

No not at all.

Threaded axle yo

Use the double nuts on the outsides of the bearings id, can even use one of the old threaded inner race guyee as a nut

Wouldn't the axle slide through both bearings and the spacer , like on just about any other bike ?

Re: Mag Wheel: No spacer between bearings

It’s like how the old style kart guys do axles.

The inner races aren’t locked to the axle

Re: Mag Wheel: No spacer between bearings

I don’t get what’s so hard to understand here.

1. Take a threaded axle for open moped bearings

2. Push thru inner sealed bearing races

3. Thread on 2 nuts per side wedging them together so they just snug up the sealed bearings inner races but so they do not pinch

4. Add spacers to the outer axle to take up space between the swing arm mounts.

5. Enjoy

I know what you're describing .

It seems maybe some do not .

Re: Mag Wheel: No spacer between bearings

I discovered this on a Paz build, that orange maxi N ass destroying monstrosity.

He did the rear mag like that. It worked just fine btw

Re: Mag Wheel: No spacer between bearings

With Maitys heft, those inner races would just settle on the axle and the bearing would do it’s work. Floating inners dawg try it if you have to.

I run spacers but if you fuck up spacer length it’s even worse than this floating way. If you make the spacers too short you’ll pinch that shit still as you tighten the axle to the swing arm or forks

Re: Mag Wheel: No spacer between bearings

I got it, but you said "inner races" in your first post, which I took as the inside races, which would be inside the hub.

Still wouldn't work if you had to remove your axle to take your wheel off.

Re: Mag Wheel: No spacer between bearings

Sure it will. Just have to do a lil cuttin to make holes into slots lolz But generally mopeds have axle slots and we’re on a moped forum.

Re: Mag Wheel: No spacer between bearings

Why wouldn't it work ?

Just loosen nuts and turn the axle . Might want an extra hand for a minute , but ... ;)

Re: Mag Wheel: No spacer between bearings

Would work but would be super tedious

Re: Mag Wheel: No spacer between bearings

Lazer mopeds have closed drops in the swingarms, and a lot of the EBR forks are closed.

I mean, I guess, if you want to stick the axle thru the hole, add a spacer, twist on a couple of nuts, keep twisting the axle till it get all the way thru, then twist on some more nuts...

Then, if you have a drum brake plate, you go, uh...

Then untwist the axle back off, take your wheel back out, balance the spacer in-between the brake plate, hold it all together while putting the spacer, two nuts, spin it thru the wheel, thru the spacer, thru the brake plate, twist on two more nuts with your fourth hand, keep twisting till your axle is centered, then grab your two skinny cone wrenches that you had to buy just to do this, tighten one side while in the frame, then tighten the other, then finally put the nuts on to hold the wheel on, and hope you don't have to keep redoing it so you don't have any side to side play...

Then yeah, much easier than popping out a bearing and using a spacer.

Re: Mag Wheel: No spacer between bearings

LOL , I never said it would be easy . Just that it could be done . ;)

Re: Mag Wheel: No spacer between bearings

@baird

Lmao @ 4th hand!

But I do like the jbot work around if you do have drop outs on your forks. I have totally done this on my front wheel when converting them over. I then made sure to remember to get the spacers in on the rear wheel. Oddly enough the rear wheel was the one that threw the bearings and had to get rebuilt. I then decided to rebuild the front one at the same time to include the spacers.

Re: Mag Wheel: No spacer between bearings

Things would be a lot easier if the swing arm was slotted to the rear and incorporate chain adjusters .

Something like :
