TheProCore Processor uses several pulley assemblies
to drive the jack shaft, chopper axle, brush shaft and ro-
tating corner shaft. Service of these pulley assemblies
requires similar procedures.
3. Slide pulley and taper lock bushing onto shaft. The
pulleyshouldbepositionedtotheinsideofthetaperlock
bushing. Make sure that tapered surfaces of pulley and
bushing align.
Duetopulley design, thelocation ofthepulley assembly
on a shaft is adjustable. Before loosening the pulley as-
sembly, measure the distance from the end of the shaft
tothebushinglocation.Duringtheassembly procedure,
use this measurement to provide the initial location of
the pulley assembly on the shaft. Final pulley location
should be determined after the drive belt is installed on
the pulleys by carefully aligning the drive and driven pul-
leys. Position of drive and driven pulleys is also depen-
dant on idler pulley location.
4. Align threaded holes of pulley with non--threaded
holes of bushing. Loosely install three (3) cap screws
with lock washers to bushing and pulley assembly.
IMPORTANT: DO NOT fully tighten taper lock bush-
ing cap screws until after the drive belt is installed
and the pulleys are properly aligned.

6.
Install drive belt to drive and driven pulleys.
Using a straight edge across the face of the drive
pulley, verify drive belt alignment across drive and driv-
en pulleys. Move pulley being installed so that drive belt
and straight edge are aligned indicating correct position
of pulley on shaft.
