    Clutch Job.....Pilot Bearing Got Stuck on Transmission shaft !

    This was one of those things that happens during a project that eats up time.

    I read that the pilot bearing typically sticks on the flywheel retainer but in my case it was stuck in the tranny input shaft. Not sure if this is common, but may explain why it took a little bit of prying to separate the bell-housing from the engine.

    Anyways, we tried an extraction tool and a few other tricks, but we ended up welding a hammer puller on the inside of the gutted pilot bearing and that did the trick.

    That's the centering sleeve. It always is stuck in the tranny output shaft, and is a PITA to remove (I normally just leave it in). I removed it using a a hooked tool.

    Is there a reason it can't be left in?

    Its been said many times before, Never ever change the bearing unless you absolutely need to. You can cause problems internal to the tranny beating it out of the input shaft. Best practice is to clean it, inspect, and re-grease it as necessary. I know this doesn't help you at the moment but hopefully it helps others in the future.

    Should have done some reading first. After my run in with that bearing I started posting in nearly every clutch thread telling everyone to leave the bearing alone and not to replace it unless it is causing issues. Most seem to have heeded my advice, but it seems those that primarily live on e90post are doomed to repeat the past. I suggest you spend more time over here in the future. Your sanity and car will thank you.

    I was discussing this with someone the other day, and to me it didn't seem apparent that you really needed to change it unless it was clearly damaged/scored. It's stuck to the hardened steel shaft, and in the case of the person I was talking to, they just cut it off using a grinder, which failed to marr the shaft underneath, luckily for them. I wouldn't recommend that. Lol.

    Skip it for sure. Don't waste the energy.

    If you have the right hydraulic BMW tool, changing it out is not that bad. If you're like me (and most people) who don't have the tool, it can suck. Let me put it this way, I called the local BMW/Mini dealership and they said they don't even replace that part when they're doing a clutch job.

    Try the small grease gun method first and if you have no luck with it, skip it. Don't smash it with a chisel though.

    I wish I started a thread here and I wish you screamed in my face not to touch it.

    I really regret not researching it enough. Please, keep telling people not to change it. I know I would have appreciated it.

    How did they get a grinder to fit in that small diameter? I thought about it for a second but decided against that method or using heat.

    I think this is sound advice after quickly trying the grease gun method. It should only take a few minutes to find out whether it works or not. The gun with grease is $10 at Harbor Freight. But yeah in general, skip it.


    Good news guys. My friend got it out while I was at work. He used a drill to make the hole bigger and then stuck a screw in there to pull it out. Not the best way but I wasn't there to suggest the grease gun method. Welding on second thought might be too hot for a tranny. It could damage seals and what not so I'm glad we didn't go that route.
