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

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.

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

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

Thank you *so* much! You just saved me $300 for an arbor press and untold number of ruined bearings.

thanks for posting this video im currently installing a new Bearing in my Yamaha PW 80 2 stroke and I wasn’t sure how to go about this keep up the good work!

this helped out tons! best sweat bearing video out there. all i used was my oven. thanks.

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.

Thanks. Will put your technique to good use. You are very skilled.

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

Thanks great vid and well explained. Will be using this method on my next engine rebuild. Thanks Again - Darren

Great job on the video and explaining what you're doing, top notch.

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.

My mind is blown!!!! So so awsome!!!

Excellent video, thanks for sharing these skills!

Thanks for video, I used the process with a Yamaha 660 case out of a Rhino / Grizzly I had mixed results, One of the bearings dropped right in as seen on this video But the other 10 took tapping, or using the press and or using a hammer to set them in. Just keep moderate expectations with multible options open.. I put the crankcase assembly in the freezer, put on vise, and put the case over top and used a 4lb plastic mallet to tap case down onto bearing..

awesome explanation, thank you very much for the video and sharing your knowledge

Thank you for your time n sharing your knowledge. I appreciate it, Big time.

Thank you for sharing your knowledge.

Excellent explanation

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.

Thanks for sharing that trick I'll be using that method from know on

chears buddy, just about to change bearings on a BSA b40, this will be a great help 👍

awesome vid man thank you for the upload

Really helpful - thanks for posting

Thank you for the video!

Very well explained

I run a small engine/ATV shop and I think you did great. You've got me beat with the heat. I tried it out on a Yamaha rt100 and never tried it again.. I think I was just too chicken to heat up my case halves hot enough.. Maybe I'll try it on the Quadrunner I have to wrench on today. Good vid

Thank you, lovin your method and enthusiasm 👍🌈

Great video

helped me a lot👍🙏thank you

Great video!!! Thanks

Great video. Thanks.

Thanx! Helped alot!

Great tutorial cheers

Very good video

Not 720p =/ Great video and a very good job explaining everything Stevo!

Hey very good video bud

So 50k views 🙈 wow that's amazing! I haven't posted much ( lol ) bit would you guys be interested in more content?? If so what would you like?

Brass works very well for heating inner bearing race. Just put the round brass rod slightly larger than the inner bearing race and heat the brass..

Used electric ovens are plentiful and cheap if they've cosmetic damage, and easy enough to place on a wheeled dolly for easy movement about the shop. They're also nice for heating heads for valve guide installs etc.

It works!

Thank you getting ready to tear into a yz85 for the first time

Yea I know ... It's not the greatest quality at all...eventually I'll get a decent video camera :)

20mim total time in the oven? Or 20min after it is preheated?

Sir why the other mechanic the make it heated was tge bearing itself.it doesn't effect on those way?

Top man

This seems so easy. Why are there videos of people needing to use stand-alone crank puller tools?

a question , why you have to heat up the hole case in the oven while you can just heat up the area that you need with burner ?

Yep not the greatest quality ... Eventually I'll get a decent video camera:)

When I use this method I better get the bearing dropped in straight the first time, cause if it wedges the bearing gets hot and I have to start all over. Though they’re usually magnesium cases I’m working with, and they’re painted so can’t get them too hot

Any tips on removing a crankshaft bearing from the crankshaft

This is crazy. Are those bearings old? I use this method but the second I drop the bearing or crank in the heat evens out and the bearing or crank is in there solid, I can't take it out multiple times like you. I freeze the bearings, do you think that is the reason?

Ugh how is it so easy for you? I’ve done it the same way except using a torch to heat the case and it didn’t work

Will this work for a pit bike crankcase such as the heat ?

Mate props to you. This was the most impressively clear, concise and invaluably informative video I've seen. No bullshit, just really priceless information. However I'm having issues, and you might not reply to this let alone reply before I have a go and fuck my transmission casing up for the 2nd time. But basically, I'm pressing a brass sleeve bush into my a brand new aluminium transmission casing. The casing is roughly the same thickness as your casing in the video but has paint on the other side. Food paint which is why I bought thw casing. So I wouldn't want to melt it. On top of this the hole for the brass bush to fit isn't just too small, it's smaller than the exposed hole in my original casing. Almost as if the bush installation permanent increases the hole size or the manufacturer drilled the hole larger before hand. I would say where the bush is roughly 8-10mm diameter, the hole is nearly a whole mm smaller. I've seen tight fits before but because the piece is comparatively a lot smaller than your bearings, I'm concerned that even a blow torch, freezer and press wouldn't get it in without breaking the brass bushing. Any ideas what to suggest. Machining the bush down is my best idea so far. I'm also concerned that too much heat on the inside of the case might melt paint on the outside.

Hi I love your video .. i have this problem i was changing the water pump shaft when i put the cases back together and tide the bolts the piston won't spin if i untied them the piston spin normal do you have an idea what can that be

Hi mate can u sweat it in when u joining both of crank cases bk together?

Wow…

Keep calm & install your crank😂😂 ffsk

Is that 106 or 160 degrees?

ir gun ~ maybe some temps instead of guessing

Turn your phone 90 degrees

*Tries to fit crank with hot cold method, doesn’t go in, sees this video and feels mocked* “see how I can instal and uninstall many times, see?” ..... -.-
