two spacer sleeves will drop free. Slip the axle assembly through one side of the caster yoke, through a spacer sleeve, a spare wheel, the other spacer sleeve and finally through the other side of the caster yoke. Then tighten the locknut on the end of the axle assembly.

Lower the mower off the jack and continue mowing. The wheel with the leaking tire should be taken to the maintenance area, the tire inflated to 20 psi and the wheel placed in a large bucket of water. Carefully inspect the tire, rim and valve for escaping air bubbles which indicate a leak. Mark each leak with a yellow marking crayon and then deflate the tire to 8 psi and repeat the inspection. If the leaks you find are pin hole size to 1/16" diameter, the tire can be repaired using an aerosol can of tire inflater and latex sealer available from any auto supply store. Follow the directions on the can. If the leaks are larger than 1/16" diameter, the tire can be repaired with rubber plugs also available in a kit from any auto supply store. If the tire bead is damaged, a tube will have to be installed in the tire or the tire will have to be replaced.
