DRIVE
SP MODELS ONLY
Chains and Belts are normal replaceable wear items. A new
chain should not be used on worn sprockets. Sprockets
should be replaced when replacing chains.
BELT ADJUSTMENT
As V-belt wears, adjustments may be required. Adjust belt by
tightening or by loosening clutch cable nut as required. See
figure 3 & 4. When replacing belt, see impeller removal on
page 10. See parts list for impeller bolt torque specifications.
DO NOT OVER ADJUST.
With machine not running, oil chain using general S.A.E. 30
weight oil every 25 hours or as needed. Note: Be sure that
entire length of chain is properly oiled. Oiling only a few
positions in the chain rotation will not properly oil the chain.
CHAIN LUBRICATION
CHAIN ADJUSTMENTS
1. Remove chain guard
2. Inspect chains and sprockets for wear, lubrication and
tension. Replace if badly worn or damaged.
CHAIN TENSION AND ALIGNMENT
3. Install new chain, locating keeper clip of chain connecting
link on inboard side of chain.
4. Reinstall bearing onto axle and assemble bearing
mounting screws. Leave screws only partially tightened.
5. Push bearings outward against each rear wheel, fully
spreading wheels to both ends of axle.
6. With bearings pressed fully outward against wheels,
keeping axle square with engine base, align and tension
chain, and slightly tighten front bearing screws first. Then
slightly tighten rear bearings. (Note: Tightening front of
bearings first, helps keep chain tight.)
7. Recheck chain alignment, tension and axle squareness. If
ok, fully tighten front and then rear bearing screws. Repeat
adjustment steps if necessary.
8. Check chain tension and roll wheels to be sure there are no
excessively tight areas in the chain. Readjust if necessary.
A slightly loose chain is better than an over tightened one.
9. Reinstall chain guard.
10. Reinstall spark plug wire.
Inspect machine for loose bolts before starting engine.
