gunnin4elvis Posted November 19, 2017 Report Share Posted November 19, 2017 Hey all, I'm getting ready to swap my crank with a max load and tz. I have the crank in the freezer and wondering what techniques have worked best for you. How do you heat the bearings to get them off the crank and how do you heat the new bearings to get them on. Was thinking torch for bearings on crank, and oven?? for the tz and max. All suggestions will be appreciated. Quote Link to comment Share on other sites More sharing options...
IceracerX Posted November 19, 2017 Report Share Posted November 19, 2017 Use a proper bearing seperater and a press! Quote Link to comment Share on other sites More sharing options...
Toybreaker Posted November 19, 2017 Report Share Posted November 19, 2017 Heat the new bearings to 275-300 use welding gloves to put them on. Make sure to put it on straight. If you cock the bearing you will fuck up the crank. there is only a .0004”-.0007” press fit heated properly you wont need a press to put them on.

sleeper06 Posted November 19, 2017 Report Share Posted November 19, 2017 Use heat on old bearings,use a tapered punch or seperater until you get it in press or puller on it. Installing new ones , welding gloves and 10 thou on each side just the inner race, I use map gas . If you get that uncertain Pm me your cell number and I can send you a video of me doing it later. Keep in mind I have made tools to do crank work over the years Quote Link to comment Share on other sites More sharing options...
