Replacing the axle bearings in the EH have removed the old bearings and retainer rings, pressed the new bearings on. Best to just press the retainer rings on or heat them up and srink them on? Theres a rubber lip seal in the bearing so cant put to much heat in that area.

I usually sit a bit of pipe over the axle, and beat fuck out of it with a sledgehammer to drive lock rings on. I got caught out recently when using heavy wall pipe. And the ID of the pipe was less than the diameter of the axle. The pipe bottomed, and I couldnt get the bearing home. Figured it out eventually, and used a drift to space the pipe up.enough to drive it all the way home.

I use the retaining ring to press the bearing on. Doing it like this means all the force of the ring is concentrated on the part of the bearing you want to be pushing on. The bearing and the ring seat together. There is not  hammer or torch in sight when fitting bearings and the operation seems smooth as fuck. A decent press and appropriate jig helps though.

Read the fine print in the blurb TIMKEN enclose with each of their bearing sets .... don't use heat it says the last time I read it.  Re using heat - I'm guessing the same school that taught you to use heat on the shrink ring also taught you to use heat on the end of an axle before you went at it with a piece of HSS. Its all oldschool thinking I reckon. You can tell when a ring has been put on using heat ... on a Hilux axle the rubber seal is all blistered/fucked looking and the BW's and 9 Inches sometimes have a blue hue going on.

All that said though, I have never heard of any axle mishap occurring due specifically to what method was used to fit the retainer ring, but fuck hammering bearings.

Yeah hammering bad. Mild controlled heat maybe ok but rubber/plastic seals kinda limits that to maybe 80c . If no seals you can go a little bit hotter but you don't want to start smoking the grease/oil

You can buy job specific bearing heaters. 

I dont beat the bearing on. Even C3 bearings run a fraction of the interference that a lock ring does. Couple of taps is usually enough to seat the bearing.

Righto so no bashy bashy or heat needed. Thou I did learn a very good lesson dont over press the lock rings with a 63t press and two straight bits of steel supporting the bearing. I just thought I'll give it a wee bit more. Must have stretched the rings out shape the farking things fell off! So today armed with new lock rings I used the baby 10t bottle jack press and some better support plates, all went ace. Now to put it all back together.
