62. Select one new:
195-352D WRENCH OPEN END 2 1/2
Place the open end of the wrench over the nut of the
keyless hub
(not visible in figure).
63. Slide entire keyless hub assembly toward shal-
low axle weldment, until assembly contacts wrench
(and
3 ⁄
16
in or 5mm spacing gauge on newer drills).
64. Use a dowel to drive the sprocket teeth, tightening
the nut so that the outer collet expands and cap-
tures the sprocket
. Check sprocket-hub align-
ment, and seating of wheel hub, during this process.
Secure until gentle taps no longer tighten.
65. Rotate either wheel hub to further tighten keyless
hub on spindle. Secure to hand-tight. Leave
wrench
on hub nut.
Fully Tighten Keyless Hub
Refer to Figure 25
66. Select one new:
195-355D WRENCH SPANNER 6 BOLT HUB
and six new or saved:
802-104C BOLT WHEEL 1/2-20X1 90-DEG
Loosely insert the bolts in the temporary
hub , leaving enough space for the
spanner to fit under the bolt heads.
67. Carefully check that spindle will be turning in the
correct direction to tighten inside collet to hub nut.
68. Place a length of 1 3 ⁄
8
I.D. pipe over the spanner
and tighten the spindle-hub assembly to at least:
300 ft-lbs (407 N-m).
Do not exceed:
409 ft-lbs (555 N-m).
The suggested 300ft-lb/407N-m can be achieved by
applying a known force at a specific distance from
the spindle center. If applying dead weight, the pipe
must be at horizontal.
