Troy-Bilt 665B - Manual (Page 22)

22 Section 5: Maintenance
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to
a complete stop, remove ignition key on electric start models, disconnect spark plug wire and move wire
away from spark plug.
Failure to follow these instructions can result in serious personal injury or property damage.
WARNING
3. Pull the reverse clutch belt downward
and slip it off the transmission pulley (L,
Figure 5-22).
4. Use two 1/2" wrenches to loosen the
belt guide (R, Figure 5-22) on the reverse
idler arm pulley. Try not to remove screw
(M) or pulley.
5. Remove the reverse belt and pull it out
through front of transmission housing.
INSTALLING REVERSE CLUTCH BELT
1. Stop engine, allow it to cool and dis-
connect spark plug wire before working
near belts. Also remove ignition key on
electric start models.
2. Install the forward clutch belt (see
Installing Forward Clutch Belt in this
section) before installing reverse belt.
IMPORTANT: 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 (N,
Figure 5-22) and transmission pulley (L).
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.
3. Insert the belt down into the front of
the transmission housing. Work the top
half of the belt under the belt guide (R,
Figure 5-22) and onto the reverse idler
arm pulley (N).
4. Insert the belt down into the front of
the transmission housing. Slip the top
half of the belt onto the reverse idler arm
pulley (N).
5. Pull the belt downward and loop the
bottom half of belt around the front groove
of transmission pulley (L, Figure 5-22).
6. Mount the belt guide between the two
flat washers on the idler pulley assembly
and tighten snugly. The guide needs
adjusting before fully tightening.
7. (You will need an assistant to help with
this step.) Pull the reverse idler pulley (N)
up to its highest point and position the
belt guide (R) horizontally level as shown
in Figure 5-23. Securely tighten the screw
and locknut (M, Figure 5-22).
8. Pull back on the Reverse Clutch
Control knob and make sure that the
reverse clutch belt fully contacts the
groove in the engine pulley (I, Figure
5-20). Release the knob and make sure
that the belt is not tensioned against the
reverse engine pulley (I). The belt may
slightly contact the pulley, but not enough
to turn the pulley. Adjust the cable for
less belt tension if the belt presses to
firmly against the reverse engine pulley.
See Checking and Adjusting Reverse Belt
Tension.
9. Reinstall the belt cover and secure it
with two flange locknuts.
10. Test the unit in an open location.
TILLER ATTACHMENTS
The attachments listed below are available for your tiller. The information is the most current at the time this manual was printed.
Contact your authorized dealer or the Factory for current information.
HILLER/FURROWER — MODEL OEM-290-250
The furrower blade attaches to the back of the depth regulator assembly and is used to create rows, trenches and ditches up to 8"
deep, depending on soil conditions. The two hiller wings attach to the sides of the furrower blade and are used to make hilled rows
and raised bed gardens.
ROW MARKER — MODEL OEM-290-257
The row marker attaches to the hiller/furrower attachment and is used to scratch lines in the seedbed for laying out furrows,
trenches, raised beds, etc. (eliminates the need for stakes, string and measuring tape). The row marker is adjustable in length from
28" to 49-3/4", allowing you to vary the width of the marked rows, as required.
