Are you prepared?
Loosen the belts, put a 1/4" extension to the slot on the pulley.
Use 24mm socket on the pulley, I used 3/4" set for leverage.
This is what you get.
Use 90 degree bend pliers, I needed to hammer it as the bottom of the ring was stuck.
Start taking it apart. (note: the bearing should not break like that...)
It should come apart easily.
Mine did not.
Used some socket from the 3/4", a 10mm steel plate and M16 treadbar to initially pull it a little.
Then used a 76mm (I think, it was from scrap pile) pipe to fully extract it.
Sanded the housing and ring groove a little with fine paper.
The wheelbearing is little different. I dont think it really matters which way you put it, but I put the rounded edge towards pulley.
Greased it and started pulling the new bearing in with the same steel plate, hammered it to get it start straight.
Bottomed it with 10mm thick washer that was 1mm smaller in diameter than the bearing itself (spares from a harrow).
Hammer the ring back into place.
Put it all back together.
Needed to remove the suction pipe so topped the fluid.
The source I referred earlier said his bearings came out with almost no force (coupe/HGT).
