Bearing Punch Tool
Submitted by Jackfrost80 on Fri, 2015-08-14 07:37
Does anyone know where I can buy a tool to punch the races out of my hubs and then knock new ones back in again? So far I’ve tried Repco, BCF, Supercheap and Martin’s Trailer Parts with no luck.

Punch
Any punch, cold chisel or drift will do to get the old ones out and then use the old bearing cones as a drift to put the new ones in

Wise man of the west, thats Carnarvonite.
Yep , and best way to use old bearing cup is too cut a slot in it with a thin grinder cutting disc
all the way thru , and it will contract just slightly , making it a perfect fit/drift to bang new one in, without itself getting
caught up.
Put it away for next time too!, just as ranmar says below.

Hammer and
Hammer and punch/socket/extension/anything that isn't made of wood really.....
Hit it in 3 places around the cup to keep it straight.

What carnarvonite said.
I've never seen a tool specifically for that job, just use a large punch or cold chisel. Round end is better as it won't score the mating surface . Grind down the old races to make them an easy slip fit in the hub. It doesn't take much to do,and you only need to do it once. Then use these modified races to drive the new ones in, makes it easy to keep them square as they are driven in. You then keep these in your toolbox for ever.

Just my 2 cents worth
Be mindful if your going to belt two hardened surfaces together bits can fly off.
I prefer a bronze type of drift.
Either way all of the above will work.
Just something to think about, PPE doesn't go a stray.

Martins trailer parts if you buy your bearing there have a press to do the job. If you take your hubs in im sure they would press them in for you.

As mentioned a chisel, drift
As mentioned a chisel, drift etc if you need to belt them out. No need to use anything at all to belt them into place. Just chuck your races in the freezer for 30 mins before you put them in the hubs. The cold will contract the race & it will just drop into place. If it doesn't, return the race to the freezer & when the missus isn't looking chuck your hubs (cleaned) into the oven for 10 mins (oxy or blowtorch with do instead as long as your carefull). Take the hubs out of the oven & drop the races in straight from the freezer. Leave the race side of the hub facing upward until the temperatures have returned to normal.
Alternatvely make your own press from a something like a 250mm M12 bolt, a couple of large washers or steel plates & a suitable nut. Google DIY bearing press to see what I mean & how to use it.
