Seized Transmission Bearing

Recommended Posts

Ive got a seized transmission bearing that im trying to replace. Problem is that you cant get at the back of it bc of the casing. And all the bearing pullers ive tried are to deep as there is only 2-3mm clearance between the back of the bearing and the motor case. Any ideas?

You should be able to get it with one of these.

Another option is to heat the case in an oven and simply tap the case against a block of wood until the bearing falls out.

I have seen that bearing fail once before. I determined the customer was forcing dirt and water into the bearing through the clutch lifter arm seal (from pressure washing).

I havnt seen that specific motion pro bearing puller before. Have an details on it? And also will heating the case hurt the integrity of any of the other bearings seats as they are good still and i dont plan on replacing them.

I have that bearing puller set and have used it many times. It's about $200 so you may not want to buy the set unless you do alot of mechanical work. Maybe call around to your local shops and see if someone will pull it for you. The heat method will work too. No worries with heat as long as you heat the entire case and don't try to do it with a torch. Just don't melt your seals..

Yeah seals are all already pulled. So heat method wont do any harm there. My question is if i heat the whole case and tap the whole case whats to keep the other bearings from coming out as well? As those do not need replacement.

Nothing will keep them in, but you can always just put them back. Its not like if the fall out, they aren't any good anymore... :ride:

Id love to have one of those puller sets though.. :thumbsup:

Here's the MotionPro set from TT.

I didnt check the discount, but its usually about 10%

If you are already this far, we don't even want to hear that you are cutting corners and not replacing everything in those cases while its apart !

Man if you felt these bearings you wouldn't replace um either lol. Got the bike on a steal from an unloving/needing money owner. Its getting all new Seals and gaskets, crank Carrillo rod and piston. Besides compared to my R6 splitting these cases is a breeze

      I just bought a Magura hydraulic clutch for my 2014 CRF450R.  Bought it thinking install would be easy, and I'm not sure that's the case now that I have the product in my hands.  I have searched the forums, YouTube, etc for install help specifically for my model year (2013 and 2014 are same really), and haven't found anything specific for the 2013-2014 model install at all.  Instructions from Magura are TERRIBLE, and are not specific at all to the Honda - generic instructions - so I'm debating if I want to return the product, cuz I don't want trouble or a big install job.  Question: for the 2013-2014 CRF450R install ONLY of a Magura Hymec hydraulic clutch - other model years are different and thus it won't be helpful for other model years - do you have any tips or feedback?  My concerns are below...
      1.  The 2014 model has a sleeve behind the clutch actuation arm that the Magura clutch slave cylinder fits into.  Stock, the sleeve holds one end of the cable, with a nut on the other end to keep the cable end tight in the sleeve.  The Magura slave cylinder, however, slides into the mounting sleeve  - but does NOT have a nut: the tension from the clutch actuation arm pulling on the metal Magura slave cyl tip end is apparently supposed to keep the Magura slave cylinder tight in the mounting sleeve.  Q: Will the Magura slave fit in to the mounting sleeve easily, stay tight, and is there any adjustment needed in order to keep the 4-6mm of freeplay that Magura recommends?  How easy is it to get the Magura slave fitted into the sleeve and the metal tip in place?  Is there enough freeplay between slave and tip end to mount in actuating arm AND the holding sleeve, so that the holding sleeve doesn't need to be unbolted?  
      2. The stock clutch cable and OEM setup runs out of the mounting sleeve (see pics marked "metal starts", and then runs through a metal sleeve that routes the cable through the engine compartment - keeping the cable away from the hot parts of the engine case, so as not to melt the cable insulation (I believe).  That metal sleeve is about 6-8 inches in length.  The Magura clutch cable, on the other hand, exits the Magura slave cylinder at an angle - yet has no such metal routing.  I don't think the OEM metal routing sleeve will accept the Magura cable either, so a) the OEM metal routing sleeve would have to be removed first before installing the Magura - and then b) you have to hope that the Magura cable can be routed in such a way with zip ties holding the hydraulic line that line will not touch or be close to the hot metal engine casing as you route it through the engine.  Q: how easy was it to get the OEM clutch cable and metal routing sleeve out?  Easy as unscrewing the nut on the other end of the OEM cable, on the other side of the black rubber cable flange in my pics?   
      3.  My stock clutch pull isn't bad.  I just like the feel of a hydro clutch.  Any feedback on how much better feeling and easier pull will be with the Magura?  What's your feedback on the difference?  FYI, I'm leaving my clutch plates and springs stock.

      We have a 2016 CRF450R with about 11 hours out. never ridden hard always check the oil and change when needed along with the air filter. Took care of the recall that was required as well. Well when riding the bike was stalled out. Went to try and kick start the bike again. the kick start lever just back up jamming my knee into the handle bars and some how ended up cracking the case right by where the kick start goes through the case. Has any one had this happen or heard of this happening? What is the cause?

      Any advice on what should be replaced while I have the top end off for a valve replacement. Will do headgasket and springs of course, anything other parts you would recommend while I'm going at it?
       
      Thanks!

      The dirtbike is on it's forth year right now on the same motor job. I have to jump start it. Is it worth me trading for a 2009 650 brute force with7000 miles? Need some expert advice. Thanks

      Just wondering what you guys do to remove black marks on your seat. My 08 crf450r has the red/black seat, and after each ride there are some black marks on the red from my riding pants. Not scuff marks, more like patches of black residue from my pants rubbing on the seat. I’ve tried the magic eraser which seemed to do the trick, but lately they seem like they aren’t coming off. Also tried scrubbing bubbles with a brush and no luck. Not too worried cuz I have an spare OEM seat, but I’d like to keep this one nice. Any ideas? Maybe I shouldn’t wear black pants?
