'Sweating In' bearings into cases-the safe way to install b

Here I have my spare engine cases and some old bearings to demonstrate 'sweating in' of bearings into the cases. Also I show how to easily install the crank without the use of crank pullers etc. few things to remember:
Gradually heat cases at 160 degrees celsius for 20 mins.
Make sure everything is clean.
Be calm!!
You have aprox. 1-1 1/2 mins to install bearings.
Only slightly heat the bearing inner to install the crank.
Sorry I'm not the best at making videos...a few small mistakes...heat the cases in a cold oven(???) oops!!!

Nearly 7 years after this video was made and it is the best one so far explaining this process. Straight forward and to the point. Thanks Steve!!! New subscriber.

Just replaced all 10 bearings and crankshaft in both crank cases in under an hour, no tools required, many thanks.

This is the best tutorial on bearing and crank installation I have seen so far. Great job.

[@averyblanton301]

Best explained yet! Thanks for the lesson on how to DIY video and the talk through step by step.

Thank you

Awesome idea with the socket and extension to head the inner race. I've used a small torch directly on the inner race in a circular motion, but like the even heating transfer method a lot more. Glad i watched this, I just removed the old bearings and crank from a DRZ400 last night, and its going back together tonight.

Very well demonstrated and explained! Haven't seen a better one yet

Thank you for sharing. This is great information. I was uncertain above temperatures and times.

Awesome video. I just cancelled my order for a new crank puller. Will be implementing this method in my next video for my kx250f build.

Good video. I rewind electric motors and we have a bearing heater for placing bearings on a shaft. You can use a propane torch and place the old bearing flat on a surface and place the new one so it's vertical on the old one so you can rotate it while heating the inner race. Doesn't take much heat and works well. Easy to do but hard to explain it with words.
