How do you change a agricultural wagon wheel bearing?

Answer 1

They may not all be the same, but in general -

tap off the hub cap

remove the split pin that goes throught the first nut you see

undo the nut

pull off the wheel complete with bearings

pick out the inner race of the outer bearing

with a suitable punch through the centre hole punch out the outer race of the inner bearing

turn the wheel over and punch out the outer race of the outer bearing

tap a new outer bearing outer race into place

turn the wheel over and tap a new inner bearing outer race into place

insert the inner bearing inner race into place

put wheel onto axle

put inner race of outer bearing into place

screw the nut on

tighten nut securely to push all bearings into place, then back off so that it's just slightly loose.

Put split ping back

Replace hub cap.

But you may not need to replace all the bearings because they may not all have gone. Check what you need to buy first.
