5.
Slide wheel off axle. Wheel may have a tight fitting on the brake disc pins and need to
be bumped off with a rubber mallet or block of wood. A three pin adapter is attached
to the back side of the wheel as shown below. These three stopping pins engage the
brake disc, which passes through the brake caliper when turning. When the brake
pedal is depressed, the caliper stops the brake disc which, through these pins, stops the
wheel.
6.
With wheel removed from axle, remove valve stem and deflate tire, then remove the
six 5/16” bolts holding the split rim together. The plate holding the brake stopping pins
will also be removed when these bolts are removed.
7.
Using a smooth flat bar, pry the rim halves off the tire. Note, there is an inner circular
disk with 2 O-rings sandwiched between the rim halves. These O-rings seal the two
halves from air leakage. If the O-rings are not being replaced, be careful not to damage
them.
8.
Put the plate holding the brake stopping pins in position on the inboard rim half and put
bolts in holes through both the plate and the inboard half of rim.
9.
Mount new tire on inboard rim.
10.
Put seal disk with O-rings onto inboard rim.
11.
Align inboard half rim bolt holes with outboard rim and re-assemble rim. Torque rim
bolts to specified values in torque table.
12.
Re-inflate tire to 15 psi and check for leaks using soapy water or a water bath deep
enough to submerge tire to center of rim.
Stopping pins slide into brake disc holes as shown above
