I still have the original 03 jackshaft locking collar on my RX1. I've done quite a bit of searching but I'm still confused on how to get that out of there. I have the special tool that holds the secondary but what I am looking at is basically round with a slot in it. Do I drive on that to loosen it? Any suggestions would be appreciated. Thanks

I think that there may be a way to do it without removing the jackshaft but I think almost everyone here that has done it removed the jackshaft to do so.
If you decide to remove the JS check the Tech pages here for track removal. Vague overview:
-Remove secondary
-Remove brake assembly and chaincase cover
-Remove JS nut/gear/chain
-Nudge JS toward secondary side to remove bearing

Thanks bdm. I looked at lakercr's post in the tech section but that deals with removing the newer style locking nut. Looks like this 03 can be removed with the jackshaft and then pulled off?

jackshaft bearing
The easiest way I found (although more time consuming) Is to remove secondary clutch, spacers, and snapring holding jackshaft bearing. Next I pull out complete chaincase, then, just hit on jackshaft with rubber mallet and shaft along with bearing will all come out on other side. Usually I'll perform this job when I change track, dueto the fact that you're right there and all the work has to be done anyway. Hope this helps.

I have the secondary off and the circlip. Tonight I plan on taking off the chaincase cover, chain and top gear. I will then drive out the shaft with the 03 locking nut attached from the chaincase side. I guess this is right bassed on what I have read? Once the shaft is out any more suggestions as to how to get the old bearing and locking collar off? Thanks guys!!!

Thanks bdm. I was going to remove the jackshaft anyway as I'm also gearing down on the top sprocket. I also don't have access to a welder. Good idea though... Can i take the shaft out and support the bearing surface on a vise and drive the shaft out? Seems like that should work?
Thanks, Bob

I am betting that a vise would work fine but I would be VERY concerned about too much pounding on the shaft and would try to minimize it. Not all bearings will necessarily be affixed so permanently to the shaft though (they are slathered with locktite or something like it) from the factory. I used my pipe trick to minimize the pounding on the shaft. I few bucks worth of parts and takes less than a minute.

Sorry for all the questions, I really appreciate the help. So if I have the JS out of the sled and take a pipe the diameter of which is the size of the inner race on the bearing and use it to tap the bearing out towards what would have been the chaincase side of the JS it seems like that should work? I'm not too concerned about the old bearing as I have a new one ready to go in.
Thanks,
Bob

I have the jackshaft out of my sled but would also like to get the bearing out on the clutch side. What are my options now? Is a bearing puller the only answer? I tried to pull it out using the jackshaft but was afraid that I'd damage the circlip. Any help would be greatly appreciated. Thanks

I can't remember how I did my pipe trick. I went back and reread my pipe trick post and, without everything in front of me, I can't picture it. Did you read my post that I referenced earlier in this thread? Maybe with the shaft and all of the parts in front of you - my description might be sufficient? I remember it being simple but cannot picture where I put the vise grips.
Sorry, that was so long ago...

getting ready to do this job on an 03. its never been done. whwt actually goes wrong with this bearing? is it bearing failure or does the jackshaft slip through the bearing and out of chaincase? there is end play on my secondary about .05 inches. is my shaft slipping or is it suppused to be like this? when i change out bearing how do i reposition the shaft?

The 03 locking collar is the problem. I have around 2300 miles on mine but the bearing seems fine. I want to update to the new threaded collar and a new bearing as a precaution. With yearly greasings the bearing should last a long time. When the jackshaft goes back in it will rest against the backside of the bearing in the chaincase. A circlip, spacer and washer prevents it from sliding any further. Hope this helps. Has anyone tried a length of pipe to push the old bearing out from the chaincase side or should I just get a sliding puller on it? Thanks
