how to change rear tires

1 comments:

May 14, 2025

To change rear tires on a 1948–1952 Hudson:

1. Remove the cotter pin and turn the wheel nut to the right to seat the parts, then back it off slightly until there is a slight drag when turning the wheel by hand.
2. Stand the wheel upright with the inner bead in the rim well.
3. Apply liquid soap around both sides of the rim.
4. Insert two tire tools between the bead and rim, pry the tire out of the rim carefully to avoid pinching or damaging the tube.
5. Remove the tube.
6. When mounting a new tire, coat both beads with liquid soap.
7. Inflate the tire slowly while checking that both beads seat properly on the rim.
8. Bounce the tire to help center it.

Also, rotate tires every 2,500–3,000 miles to equalize wear.

The oil is drawn through a pipe connecting with a floating screen in the oil pump by the oscillating plunger type oil pump which is driven from the camshaft.
