Axle spindle bushing for 312-8

[Jesse 4]

I just bought a 312-8, not sure of year, but the wheel spindles are sloppy.  I don't think there are bushings in the axle.  Just wanted to know best way to fix it.  New spindles and have a machine shop put bushings in the axle?

The 312 has flanged roller bearings. You can get them at NAPA, EBAY and most on line parts places

I think you have the right idea, just be sure you can accurately locate the bushings by using the less worn surfaces on opposite sides top and bottom.

Drill out the axle with a 7/8 construction reamer, insert 7/8 OD x 3/4 ID bronze bushings. Might as well do the axle pin as well since you bought a reamer.

Get the 1/2" shank reamer and you can drill them with just a battery powered drill. Drill half way from each side of the hole and the hole doesn't get wollowed out.

Have a machine shop bore the holes, using a reamer will locate the hole somewhere between where it should be and the worn area.

I've done a bunch with just a construction reamer and a hand drill, have yet to have any problem at all. The tapered construction reamer self centers and goes straight through. It's my belief there is no exact precision needed for a 7 mph tractor but having or paying a machine shop to do it is probably the correct way.
