2011 Patrol sidecar wheel bearing question

Postby antisoshal » Sun Mar 13, 2016 7:27 pm

I did some searching before asking and found nothing. All the how-to images and explanations I can find show the sidecar wheels having standard automotive style roller bearings. I just pulled my wheel to address some bad break surging that seems to be caused by loose bearings. Instead of roller bearings, out pops some japanese NBR+Fe 13-1 ball bearing units. Huh? Any guidance on this since at least the front one seems to have a lot of play. I cant see exactly how to remove the back one and dont want to damage anything. Also, any source on these since I can find a lot of mention of them online but no one selling them except random ebay people

What would Ivan do? Get plastered, fall off the bike and sleep it off in the sidecar.

Correction: They are NBR out of Germany and made by the subsidiary FAG

6204-C-2HRS Ordered from UK (6) for 31$ including shipping. Not terribly available here in the states. Good to have a few on hand I guess.

If your problem is loose bearings, you might want to look somewhere other than the wheel bearings. The wheel bearings on the sidecar wheel don't turn on the axle, the axle turns in the 6206 and 6207 bearings where it passes through the frame. See Diagram 05-0011 in the Ural parts catalog.

When the problem you describe showed up on my 2011 Patrol, the distance ring (#18 in diagram 05-0011) was worn out. You might want to check that out. Keep the axle nut tight and you'll minimize the wear and keep a spare when traveling.

From some notes I have on KLR650s it shows the same bearing, 6204 is used. Someone posted this part number from Fastenal: 6204 SKU: 0474391 $2.50. Someone else said they got this bearing from a bearing house in Houston. Right Rear: ......6204 47x20.........brand=SFK.. 6204 2RS JEM rubber seals.

Best,

This was not meant to be an instructional video, but you might glean something from it. This was on a 2010 Patrol.
IMHO it would be worth your time to remove the drive shaft and inspect everything. I originally thought it was my wheel bearings, but it was the bearings in the sidecar drive unit and they went bad because the driveshaft u-joint was bad.

Thanks everyone. My problem isnt loose bearings per se, its a hard throb on the sidecar wheel when the breaks are applied. I only have about 5000 miles on the bike. I was assuming it was the drum deforming from heat, but someone suggested that I check the bearings as they can cause the same basic problem. When i jacked up the wheel I found what I considered a lot of play in the wheel bearings them-self, not the axle. I can stuck a finger in the bearings and move them more than I would expect. Im gonna replace them as I already have the parts on order, and see if it fixes my problem. The inside of the drum (hub doesnt look unevenly worn and seems pretty smooth, so Im hoping for now thats not the issue.

When truing my wheels I got a little torque happy and created brake pulse. The drums deform before the rims do.

That looks brilliant. Will probably end up trying that if the bearings dont solve it. The pulse have been developing over a fair while and Ive just been living with it, but near the end of fall it got so bad it was hard to keep the bike straight at stops and the sidecar was bouncing.

Play at the wheel rim can come from wheel bearings or axle bearings.
I have seen both hubs and sidecar swingarm bearing carriers where the bearing was a loose fit right from the factory.
You have two problems, a wobbling wheel and a pulsing brake.
Fix the wobbling wheel first because a wobbling wheel means a wobbling brake drum.
Then address the pulsing brake.
