Use a spanner wrench to tighten the jam nut (J&J #
1-60-0193) on the drive side axle bearing.
Align the axle so that there is a 2” space between
the frame and the inside edge of the floater hub
brake disk; this will set the axle in the correct
position.
TIP:
Cut a block of wood with a 2” width; using a
“C” clamp, lightly snug the floater hub disc brake
rotor with the block sandwiched to frame. This will
maintain this critical 2” distance while the drive
side axle bearing is set.
NOTE: If the axle has shifted, the calipers will be out
of alignment. This will cause the brake pads to drag
and the axle will not turn freely.
Lock the axle in place using a 1-1/4” open-ended
wrench.
Place the wrench on a portion of the axle that has a
enough 1/4” key stock showing to allow the wrench
to bite.
