Troy-Bilt Pro Line - Manual (Page 23)

Slip the belt off the front of the transmission pulley. See
Fig. 7-4.
Work the belt out from between the pulley and the frame,
around the transmission cover spring, then up and out of
the machine.
From the front of the tiller, insert the forward clutch belt in
between the bottom of the engine drive pulley and the top
of transmission pulley. See Fig. 7-5.
Insert the bottom half of the belt into the smaller, rear-
most groove of the transmission pulley. See Fig. 7-4. Now
slip the top half of belt under the belt guide (See Fig. 7-3)
and onto the large groove of engine drive pulley. See Fig.
7-4.
Reconnect the forward clutch cable to the correct hole in
the idler arm bracket, as shown in Fig. 7-2.

guide.
Reinstall the reverse clutch belt. Insert the bottom of the
belt into the frame, then pull down on the belt and roll it
onto the large, forward-most groove of the transmission
pulley. See Fig. 7-5.
Reinstall the belt cover.
Test for the correct tension on the forward clutch belt. See
the Maintenance & Adjustments Section.
Reverse Clutch Belt
Stop the engine, allow it to cool and disconnect the spark
plug wire before working near the belts. Also remove the
ignition key on electric start models.
Remove the belt cover by removing the two flange
locknuts. See Fig. 6-8 in the Maintenance & Adjustments
Section.
Pull the reverse clutch belt downward and slip it off the
transmission pulley. See Fig. 7-6.
Use two 1⁄2” wrenches to loosen and remove the wire belt
guide from the reverse idler arm pulley. Do not remove the
locknut and screw.
NOTE: The forward clutch belt must be installed before the
reverse clutch belt.
Install the forward clutch belt (see Installing Forward
Clutch Belt in this section) before installing reverse belt.
NOTE: The reverse belt has a ‘V” shape. When installing the belt,
make sure that the widest (flat) side of the belt rides against the
reverse idler pulley and transmission pulley. If needed, the belt
can be twisted “inside out” so that the “V” shaped side is on the
outside and the widest side is on the inside.
