Pressing or beating AMC 20 axle bearing on

GPER · 02-12-2009, 03:40 PM

I was watching the Scout build link and at the end it showed what looked to be them beating the axle bearing on the 44 axle shaft with a piece of pipe.

Does the 44 bearing go on with less force then the AMC 20 bearing?????? I have been told beating a bearing on is a no no, but I have the bearing beater ready to go when I do mine.

Should I have it and the keeper ring pressed on or would you beat them on??????????

<--- in favor of using a press for anything that needs pressed....
but I will resort to whatever gets the job done.

Press make the job much easier with less chance of bearing damage.

If you plan on beating the bearing on use some heat to help out. ;)

if you do have to beat a bearing on... do it with a piece of tube that contacts the inner race, it's the strongest part of the bearing. YOu dont want to push on the balls/needles or the outer race. I don't agree with heat to install a bearing at all either, not direct extreme torch heat anyway. Acceptable to heat one up in an oven to expand it.

but, don't be a retard, use a press. If you don't have, get a friend with one, come down and use mine, whatever... the word "beating" should never be used with bearings unless you need to beat one off of something.

Heat a pan of oil and put the bearing in it by hanging it with coat hanger so not to sit on bottom to install. This will heat the whole bearing and not just one side .Depending on style of bearing and weither or not its got seals or not. (rubber seal or metal seal )

depending on size of bearing but from 100 deg to 350 deg will work . Any more
you can destroy bearing by possibly removing heatreat from steel.

We actually used a turkey fryer set up to do ours and be carefull not to burn the oil so whatever oil you are using make sure it can handle the heat you will be applying to it.
