Remove Arm Relay Bearings

13 posts in this topic

Should of done it sooner, but I have a bearings and collar that is rusted and will need to be replaced.  Can the bearings be tapped out with a socket or a punch?

 

Also, I'm assuming that when putting in the new bearing... you would want to press them on so the needles don't fall out?

2007 WR 450

The parts call it a Arm Relay. Parts 20, 21, and 23. The bearings are rusted. So I need those replaced.

Ahhhh, linkage 

The bearings are not caged, they are held in with grease

Yes, you can press out the races

The races are usually fine after a cleaning and polishing.

Ok good to know. The collar and bearings were pretty bad. I ordered new parts. I re-greased everything else including the swingarm. Nothing else had seized. Man I kept wondering why my rear shock wasn't raising right after getting off the bike.

Please use water proof grease

You probably got an answer for this....lithium soap based grease and the warning not to mix greases yet the heavy duty water proof high temp greases I have say nothing about lithium. I got tons of water proof bearing grease for boat trailer hubs but am afraid of the mixing greases warning. When shopping I didn't find much lithium except in small tubes. Obviously when regressing my new wr I didn't clean the grease already on just added to it. But I did get lithium grease. Ever heard of any horror stories of mixing greases?

To press them out I used some 3/8-24 all-thread with some large washers, a large socket to recieve the race and a smaller deep well socket to use as the ram.  Worked great.  Used same set up to press new ones in only didn't need large socket to receive it.

What do you mean 3/8-24 all thread?

Well I mixed the grease with water proof grease, there wasn't a ton left anyways. I'll check them again in a year.

What do you mean 3/8-24 all thread?

 

I went to the hardware store bought the metal rod that was threaded the whole length.  it was 3/8 inch diameter, 24 threads per inch pitch (fine thread).  Comes in 3 foot length.  Cut different sizes to use on different parts.  I had to replace all of the swingarm, linkage, and shock bearings.  I opened them to grease it all up as the bike was new to me and the roller bearings came out as rusted dust and the seals were all hard and torn.  Nothing was salvagable had to press out all the races and start over with new kits.

 

I made the press because there is something that just feels wrong with hitting bearing races with a hammer

Well lessoned learn, went to my neighbors and tried to press these rusted bearings out. Tried heat etc. there not moving. I could try the other suggestions. Looked on eBay and found a full linkage for 38.00. That's cheaper then just the parts with two bearings and a collar. So I'm going to go that way. Thanks for the help.
