ASSEMBLY WITH BUSHING
Clean all mating surfaces between hub, bushing and shaft. All
grease and lubricant should be removed, leaving the mating sur-
faces dry.
If there is no shoulder on shaft to prevent bushing from sliding
down shaft, slide spacer/sleeve (not provided) on shaft before bush-
ing or use a thrust retainer (optional equipment) on top of hub.
Slide bushing and key onto shaft until flush with end of shaft. The
shaft size determines the bushing type (R2, S2, or U1). Lock bush-
ing on shaft by tightening the set screw in flange with an Allen
Wrench. Line up key and set hub on bushing. Engage the three (3)
cap screws in flange of bushing into hub spool, using a torque
wrench with a socket, and tighten evenly. Use the following table
to determine the proper tools and torque values.

ASSEMBLY WITH STRAIGHT SHAFT
(NO BUSHING)
Clean all mating surfaces between the hub and the shaft. If there is
no shoulder on shaft to prevent hub from sliding down shaft, slide
spacer/sleeve (not provided) on shaft before hub or use a thrust
retainer (optional equipment) on top of hub. Install key in shaft.
Line up key and keyway and set hub on shaft. Tighten set screw(s)

ASSEMBLY WITH TAPERED SHAFT
(NO BUSHING REQUIRED)

screw(s) with lock washer(s). Shaft size determines what size cap
screw is necessary. Using a torque wrench with a socket, evenly
tighten cap screw to recommended standard per table below.
