84 200x wheel bearing replacement

[desertlee]

Can anyone provide the process for replacing the rear bearings on a 84 200x? I have the bearings, just not sure how to do the job:( Also, how about the swingarm needle bearings? I have them also just not sure what else I need to get the job done...Thanks!!

The rear bearing are fairly easy. Just set your trike on a milk crate or what ever you have so you can lift the rear tires off the ground. Then remove the axle nuts so you can pull the tires,rims,and hubs all off in one piece. Then loosen your chain and take it off the rear sprocket. They undo your rear brake and set it aside. Then just take the two axle nuts off the axle shaft. And slide the shaft out to the left(the sprocket side). Then you can take a long punch and tap the axle bearing and seals out of the houseing. Clean it all up and grease it and put your new bearings and seals in.

the swing arm bearing are easy to get at but usally tuff to get out. Just remove the nut on your long swingarm bolt and see if you can get the bolt out. If so you shouldnt have to hard of a time removing the swingarm bearings. If not then they are rusted to the bolt and going to be a bugger to get out.

Fuzzys right....Little tip tho..loosen the axle nuts before you disconnect the brakes..and im not sure if the '84's have reverse threads or not?

Nope. All right-handers.
Just did my axle bearings last week, but I still have the original needle bearings in it. They are still like new, but I'm on my fourth set of rears. I found that you don't have a lot of bite room to punch the bearing out from the other side, so I ended up tearing out the ball retainers and pulling the balls out of one bearing to get the center journal out. This allows the sleeve to come out and gives you access behind the bearing. Then I took a narrow chisel (a screwdriver would probably work) and drove it just behind the outer journal and between the little lip that stops the bearing. I tapped around the edge of the journal until I had enough space to punch it out from behind.
Don't make the mistake of using the old journal to press/hammer in the new bearing. It's a pi ss er to get out if it goes in too far. I use an old wheel bearing that's about a sixteenth of an inch smaller than the new bearing.
If you clean out the bearing seat it helps, too.
I just put some grease on the metal parts inside to slow the rust and maybe hold off a little water. But you're not doing the sealed bearing any favors by putting it in grease. I grease up the seal and the needle bearings good, though.
A nice project may be to adapt to roller bearings (which are meant to float in grease) and use a Zerk fitting to grease it up to keep the bearing area under pressure, and water out of the seals. But then there's the slinging grease, so I've just tried to get used to regular bearing/seal changes every four or five years.
Oh, and don't forget the o-ring behind the nuts!
