DRIVE BELT
To access the #004520 Drive Belt, begin your
procedure by parking your Crawler on an open,
firm, level surface.
If you have a Hydraulic
Front Hitch, lower it to the ground. If you
have a Hydraulic Loader, lift it as high as
possible, and insert your cylinder lock.
Shut
off Engine, engage your Parking Brake Lever
and dismount. Rock attachment valve handles
back and forth, to make sure attachments, will
not move.
WARNING:
Do not attempt any servic-
ing or adjustments with the engine run-
ning. Use extreme caution while
inspecting drive belt assembly and all
linkage, pulleys, etc.
Loosen and remove the two black hood handles
(not shown). Raise and remove hood. Remove
the #1688 Seat Pin. Then remove the #4562 Seat
& #1674 Mounting Bracket, #1625 Arm Rests, and
#1608 Rear Cover.
NOTE:
Be sure to disconnect
the “mating” #1829 and #1825 Seat Wires at their
common Plug.
Picture below is showing wires
for clarity. However, wire connections are on
the driver’s left hand side.
DRIVE BELT - TENSIONING,
REMOVAL & REPLACEMENT
Your RT1150 is equipped with a
#004520 Oil &
Heat Resistant, Hi-Power II Double V Drive
Belt
. This drive belt powers your left & right hy-
drostatic transaxles, as well as your hydraulic at-
tachment pump.
A simple idler pulley keeps tension on the drive
belt and minimizes belt vibration. If the drive belt is
loose, or squealing, and the idler pulley is not put-
ting enough tension on the belt, or you’re replac-
ing the belt, follow the procedure shown below.
Step 1:
Loosen, (but do NOT remove) the Pulley
Bolt and Nut shown in the
top picture
above.
Note: The area is tight, remove cross braces,
by loosening their corner bolts, if needed.
Step 2:
Push idler pulley all the way to driver’s
right, as far as possible.
