hello,
I was Reading somewhere about putting bearing in freezer before you put them in housing. my concern is that they may crack
when putting in. i dont have a press just a BFhammer and a piece of wood. anybody have any thoughts on this.

Yes this is fine......It will not crack.... The point is to freeze it to make it a tiny bit smaller and heat up the part its going to be installed in. WaAALLLAAA!!! the bearing goes in nice and easy.
If you dont have a press or a large vice ,Use a socket that's just as big as the bearing. tap it in lightly as not to ruin it. You only want the socket touching the outer edges of the bearing when striking it with your BFhammer. lol
If you send out items to be chrome plated, such as a-arms and are installing new bearings .......freeze up your bearings over night and toss your a-arms in the oven on 200% for about 20-30 minutes.
Flip halfway through cooking time and check for tenderness .[img]i/expressions/face-icon-small-tongue.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img] JK
When done smother with grease and enjoy.....lol

 

when the factory put them in the bearings were room temperature.i'm pretty sure that freezing them in a generic freezer will not cause them to crack if you give em a smack with a piece of wood.just don't dip the bearings in liquid nitrogen then hit them.i think that would cause some problems.just follow the service manual.all will be good.

 

Thanks for the input..
i think iam going to try it. i hope this weekend. still waiting on bearings from RockyMountain atv.

 

Hey Rickskingquad, Welcome to the forum. 4 posts and you already have recieved valuable info. Thanks to the other guys too. I never thought about the freezing thing. Good stuff!!! [img]i/expressions/face-icon-small-smile.gif[/img]

 

I'll only help slightly but since you don't have a press it's better than nothng I guess. A sub-zero freezer would be tons better, most home fridges are only about 32 degrees. I've always found you can get more bang for the buck by heading something rather than cooling. In either case you'ce only got seconds to do the work before it expands again.

Best thing is to put a solid support under the case, best to even have it on the floor (IE case, wood support, concrete/solid floor). This way when you smack it in the case will bounce less and it'll take less wacks.

Good Luck,
Rob

 

RicksKingQuad, what bearings are you replacing anyway????

 

Thats how I put in a cylinder liner. I machine the liner to a .002-.003 thou interferance (Liner 2-3 thou bigger than the bored cylinder) and then freeze the liner for a couple hours and warm the cylinder in a 300 degree oven. The liner falls in there line a rock down a mine shaft and when the temperatures equalize there is the .002 pinch fit just like it was welded in there. They will never be different temperatures again so the fit doesn't change.
No doubt at all. Thats how it works. lay the bearing on wax paper so nothing sticks to it in the freezer.

 

a lot of guys have some good info. i am glad i stumbled in here. Ill have to tell my son about this place he is always tweeking with his Blaster. I am replacing left rear axle bearings.
