Apc chopper rear wheel spacers
 
My sons mini chopper with dual rear wheels lost some bearings and chewed up the inner spacer between the wheel bearings on the sprocket rim. I also would like to get new axle spacers. Does anyone know where to purchase this? Also what is the difference between 6000z and 6000zz wheel bearings? Thanks again any advice is greatly appreciated!

These are the spacers off the axle that we have.

Difference between 6000z and 6000zz are the quality in the bearings...ZZ are better quality..

I'd get the 6000-2RS bearings which are rubber shielded instead of metal which seal a lot better..

There are 2 spacer tubes that go between the rim hub bearings that are like 4" long and [1] 3/16" wide spacer between both wheel bearings for both rims that spreads the tires apart 1 aluminum spacer that locks both rims together and two spacers that center the assembly in the rear swingarm along with 2 chain adjusters,2 washers and 2 nuts ...So youll have a total of 6 spacers, two washers ,two chain adjusters and two nuts.

You can go to Home depot and pickup some 1/2"od round tube and make a new rim hub spacer..

Looks like you have the two outer spacers and 1 rim hub spacer.You need a 3/8" wide x 10mm inside diameter spacer and a rim hub spacer the same size as the one you already have.

For the rim locker it can be made out of steel or aluminum fence pipe / electrical conduit..

Heres a picture of the aluminum collar that locks both rear wheels together so they both spin like posi-traction...Theres 2 pictured but only 1 is needed..

The best thing to use is a 1 1/4" EMT conduit pipe tubing......Its thin-walled, much stronger steel with a perfect sized inside diameter for the job...Ö.

In this picture the spacer tube is between the bearing and the band brake housing to properly space the band brake assembly to the brake hub

Thanks I will keep you updated. So then I believe It goes, starting from brake side,18mm, 60mm inner wheel, 18mm between the wheels, 60mm inner wheel, and then 25mm on the sprocket side.

3/16 - 3/8" spacer between the wheels

The locking sleeve slides onto one whole side of rim hub then the other side just locks into the triple splined end on the other rim hub side....

If you don't put the locking sleeve to lock both rims together when you lean to the left the rightside rear wheel is going to lift , spin then re-gain traction harshly when it pivots back causing a lot of unneeded stress on those three thin little M5 screws holding the rear sprocket on.

Good Luck

Just got a great deal on bearings on Amazon no less, and fast shipping. 6202-2RS-C3 ( 2 rubber seals ), 23,000 RPM bearing, chrome steel, 15mm-35mm -11mm. For 49cc reed port and piston port, crankshaft bearings, $14 for 10 bearing pack $20 total w/ shipping, free if you have Prime. PGN Bearings/Amazon. You need 6000ZZ-2RS bearings.
For the crank I remove one or two seals to make on open bearing or a modified seal one side open.

Cam2 can you tell me how deep you cut the slots on the locking spacer? I cut some on the threaded conduit coupling that you have linked in this post and itís kinda wobbly and when put together the spacer has play and isnít locking the wheels

The slots are pretty minimal... 1/4" on each side of the spacer..When the wheels are set and tightened the spacer should be equally as tight as the bearing pre-load against the rims...


Do you have a spacer between the dual wheels?....

If you do it should only be like the thickness of maybe 3/16 - 3/8" depending on how far recessed the bearing is cut into the rim hub...

Just enough space so both rim hubs barely touch together and will still add clamping pressure on the wheel hub bearings...

If your rimhub halves are a lil anemic due to being manufactured by a different company etc you can buy a small 6"piece of conduit pipe and cut it the same size as the spacer and recut the slots ..

On most rims a simple piece of conduit pipe itself works better than the coupler except for the 36v electric models..........

Good Luck

What is the length of the locking spacer? The inner hubs are over an inch apart with my homemade locking spacer installed.

If it were me it would definitely be worth the trouble to retrofit a pit bike back tire on to the APC mini chopper I would make the disc brakes and caliper work off the pit bike as well and never look back I personally absolutely hate the APC mini chopper double back wheel and the drum brake as well

A pitbike rear rim?????...Even if it wouldn't look to gawdy with a super huge ferris style rearwheel and a jacked-up rearend hotrod stance I guess you fail to realize that the chain and rear sprocket needs to be aligned straight to the transmission and the distance between the brakes and the sprocket is like 11.5" wide....Pitbike rims range from 6.5-8.0"...

Once the rear sprocket is lined up whats gonna take-up the huge space on the left side...?

Where you gonna find a #410 sprocket that will simply bolt on or a #420 sprocket for the transmission?


What he needs to do to do it the right way without spending a ton of money is use a Cag rear wheel setup......Ö

Ecoop3r you should of measured your rimhub diameter and spacing but youll get better results using this...Ö.

I have both rear wheels, the axle, all the tube spacers except the center one and the locking spacer.. I just need to know lengths so I can get it done right..

your right i went out and looked at the pit bike Wheels I have and it would look really funny if he where to change just the back he would have to do both back and front and it would be more money than it would be worth even with me giving him the wheels and brake calipers that I have

The CAG setup is the way to go definitely.

I personally dislike the look of the double back wheel and personally feel that a motorcycle should have two wheels and a trike should have three I have no idea what the Chinese were thinking when they came up with it but that's just my personal opinion.

With that said I have repaired a bike with the double back wheel getting all the spacers in the right order seems to be the major issue with the thing in that little spacer that goes in between the drum brake is a big deal if you don't have that it will over tighten and cook the bearings.

How about an X7 wide rear wheel??
