7. Remove fasteners (four (4) cap screws, washers
and lock nuts) that secure scraper assembly (item 7) to
conveyor frame. Remove scraper assembly.
8. On left side of machine, loosen bearing locking collar
on both idler and drive roller shafts (see Drive Roller
Bearings and Idler Roller Bearings in this section).
CAUTION
To prevent personal injury, make sure that hop-
per assembly is properly supported as it is raised
from the machine. Hopper assembly (without hy-
draulic components) weighs approximately 200
pounds (91 kg).
IMPORTANT: When raising the hopper assembly
from the frame, lift at corners of hopper to prevent
bending the hopper walls. Also, take care to not
damage hydraulic lines, electrical harness or other
components while raising the hopper.
9. Remove fasteners that secure hopper assembly with
gate assembly to machine frame (Fig. 11). Once all
fasteners have been removed, raise the hopper as-
sembly enough so that left side of conveyor frame can
be removed. Support hopper above the machine.
10.Remove fasteners (five (5) cap screws and flange
nuts) that secure conveyor bed assembly (item 2) to left
side of conveyor frame.
11. Remove fasteners that secure left side of conveyor
frame to tow vehicle or tow chassis.
12.Support idler roller, drive roller and conveyor bed as-
sembly to prevent them from moving.
13.Carefully slide left side of conveyor frame from idler
and drive rollers and remove left side of frame.
14.Rotate conveyor belt so that section of belt without
the v--guide on the bottom of the belt is around idler
roller. Slide conveyor belt from idler and drive rollers and
remove belt from machine.
Installation (Fig. 10)
IMPORTANT: Before conveyor belt installation, re-
move all trapped spreading material from conveyor
bed, belt and rollers.
1. Install conveyor belt to ProPass in the reverse order
of removal noting the following items:
A. Make sure that v--guide on bottom of conveyor
belt is in the guides of both idler and drive rollers.

B. Inspect rubber skirts that seal the hopper and
conveyor belt. If skirts are worn or damaged, replace
them before installing hopper assembly.
C. As hopper assembly is lowered to machine
frame, take care so that hydraulic lines, electrical
harness or other components are not damaged.
D. Make sure to lock bearing collars by striking blind
hole in locking collar with a punch in the direction of
shaft rotation. Also, apply Loctite #242 (or equival-
ent) to threads of locking collar set screws before in-
stalling set screws in collars.
E. Before installing drive guards, idler guards, bot-
tom guard and front rinse guard to machine, adjust
conveyor belt tension and tracking (refer to Operat-
or's Manual).
F. Make sure that rake tines on gate assembly are
not scratching the floor belt after assembly is com-
plete.
G. Grease all four (4) bearings after installation is
complete.
