To get rid of the Nasty, floating low speed bearings in the Vans tail wheel I created an aluminum spindle from a 2.25 cylinder ~0.8 dia. with a 3/8 hole down the length. I lathed each end of the cylinder down to 0.620. The bearings (499502H) fit over each end and are clamped on the inner race by a 3/8 bolt and cotter key nut which also holds the tail wheel on the Aircraft. The outer bearing race is an interference fit into the tail wheel. Outer Race – 1.375 Inner Race - 0.623 Width – 0.433 Used for 15 years now, no problem but need a new tail wheel so replacing the bearings as well. Sealed bearings so grease fitting unused.

You need these upgraded bearings to replace the poor quality ones that come with the home builders special tail wheel , (Aviation Products tail wheel) . Sky King

Bearing seems fine but the ID was off. Need to turn my bushing down or get a different bearing.

Same problem as Steve below. These bearings are listed as accessories for the Homebuilders tailwheel assembly but they do not fit the axle bolt. I thought maybe make a bushing from some EMT or 4130 I have on hand but none of what I have fits correctly. Making a bushing is the best bet but I am seriously considering converting it to a proper cone bearing.

Bearing described as replacement for API tailwheel bearing. Bearing was 5/8 in T/W is 1/2 in.
