Engine case Ball bearing swap - November 22, 2012, 02:18 PM

I am swapping the engine case of a ktm 625 sxc and the ball bearing is press fit .. I have a blind bearing puller but I do not want to damage the bearing since I want to reuse it .. I came across this video using heat technique


I also have a little piece that fits in for the oil circulation right next to the oil check window that needs to be swapped .. anything I should be looking out for?

You are tearing the engine that far apart and going to reuse a bearing?

Replace the bearing and the seal next to it. That seal is responsible for sealing off the end of the crank and pressure feeding oil through the crank to the big end bearing. Haven't you had enough issues with that poor bike to take such chances over $50 worth of parts? If you choose to remove it and reuse it I would try the heat gun but a regular puller would work better than a slide hammer style puller. Good luck man.

You realize you just told deep (the guy who almost blinded himself using brake clean in MY garage) to heat his case up to 300 degrees and then PICK IT UP to smack it against a block of wood lol....? Am I the only one who sees that ending in disaster (burnt hands, bearing scar burned into his cheek, ect) ....

It's ok lol Deep is indestructible. Just to prove my point I'd heat it to 500 Celcius. Do it!!
