The ol' bearing in the freezer trick ????

[Smokinjoe-VRCCDS#0005]

Does it work ?
I've got my bike down for new tire ,brakes,maintence on final drive and heard alittle something in the left rear bearing ( kinda of a click when rollin' it ) . I ordered a new one and was wonderin' about the freezer trick  ???

I've heard it works, same for the wheel dampers too.

If your talking about it "shrinking" so it slides in easier.....   it might work.  BUT....  I would rather tap the bearing in with a socket the size of the outter race at room temp.  Something about tappin on ice cold things with a hammer is like breaking ice cubes....   not really, but you get my drift.

It works. But you want need to do it for the left bearing. Got to the hardware store and buy you some all thread rod that will fit thru the bearing and some washers about the same size as the bearinf and nuts tio fit the all thread and use this to pull the bearing in. I really don't like to hit on a bearing and this is a poormans redneck press with thw allthrad rod. Works great and have been using this for some time now.

if you have a chest freezer they work better than the ones in your house. another trick is take an old cooler and a co2 fire extinguisher put the bearing in a ziplock bag put it in the cooler and discharge the co2 into the cooler and in about 3 to 5 minutes you have a shrumked bearing that will fall right into the hub

Like Warlock said, use all thread rod,nuts and washers ( or sockets ) Why take a chance of putting moisture in the bearings?

Why take a chance of putting moisture in the bearings?

Ditto that.  Once it comes out of the freezer and hits humid air you are gonna have condensation on/in the bearing.

Much appreciated men...I'll pass on  " The ol'bearing in the freezer trick " Again thanks for the suggestions

Any method that you can use to help decrease the OD of the bearing will help.  If you have a local source for dry ice this works real well.  You can make your own if you have a bottle of CO2 around and then release it into a box to make the ice.  We did this with a set of center bearings on a Cat wheel loader and it worked good.  One of the guys made up a box and lined it with styrofoam insulation and the dry ice lasted several days.

one would be suprized just how much this method is used............. (dry ice/freezing) anyone ever heard of boiling the bearing in oil to inlarge the inner race to make it slide onto the shaft ?

Have heated up bearings to put it on a 8 inch Frick Ammonia compressor. It's a one shot thing! Ammonia used for commerical refrigeration, 200 hp compressor.

Hands down best is an induction heater, the ones that I have used come with several different size bars that are used to sit the bearing on, just put it on and flick the switch and they heat right up, use thermal crayon to determine the temperature or a laser temperature gun so you don't over heat them. 

One small shop that I worked in we had an old electric deep fryer and used that for heating bearings, it worked well and if you keep an eye open you can pick up them deep fryers real cheap at yard sales etc.  They are especially nice for home use because you can control the temperature with the control knob and if you keep the lid on it when not in use the oil will stay clean.  Only down side is that the oil stinks a bit when it heats up so the boss may want you to use it outside.

Any way that you can use temperature differential to assist with assembly is a good thing, if you believe the failure analysis guys they will list damage caused during installation high on the list of reasons why bearings fail prematurely.

98 Valk, MN.winters at -25, many times. Bearings still good. Try not to over think things.
