1. Drain fuel from fuel tank into a UL, CSA or UN marked, European ADR
regulation approved fuel container and oil from engine crankcase. If re-
use is not possible, disposal must be carried out according to
international and local environmental standards.
2. Using 7/16 inch (12 mm) wrench, remove four K-lock type nuts that retain
engine to transmission. Remove engine from transmission and operator
handle from engine leaving throttle cable connected to engine. Store
operator handle in a position that does not damage throttle cable.
3. Position engine with rotor and shoe assembly facing up. Properly secure
to prevent movement.
4. Using impact wrench and 17 mm socket, remove two capscrews retaining
rotor and shoe assembly. NOTE: capscrew threads are righthanded.
Remove rotor and shoe assembly from engine flywheel. FIGURE 21
FIGURE 21
5. Clean engine flywheel and clutch drum areas with safety type solvent.
6. Inspect engine flywheel, crankcase castings, mounting studs and clutch
drum for cracks and other signs of visible damage. Any damaged
component will require immediate replacement.
7. If clutch drum shows signs of severe wear and/or damage and requires
replacement, refer to CENTRIFUGAL CLUTCH DRUM/PINION SHAFT
REMOVAL AND INSTALLATION in SERVICE/REPAIR INSTRUCTIONS
section of this manual. Severe wear is defined as:
a) Deep grooves cut into walls of drum measuring greater than
3.140 (79.76 mm) diameter.
b) Deep, dark blue color that might indicate sustained
operation at high temperatures while slipping. Extended and
sustained operation can potentially weaken structural
integrity of the brazed connection between drum and pinion
shaft.
8. Clean and inspect hardware that retains rotor and show assembly to the
engine flywheel. Replace any component showing cracks and other signs
of visible damage that are present.
9. Apply Locktite 609 or equivalent to the shoulder bolt threads.
10. Locate replacement clutch rotor and shoe assembly plus, thrust washers
on engine flywheel with direction arrow pointing in counterclockwise
direction. This orientation properly maximizes the torque transmitting
capabilities of the clutch. Refer to FIGURE 21
11. Reinstall retaining shoulder bolts to 5.4-7.2 foot pounds (7.5-10 N.m.).
When properly installed and torqued, shoulder bolts should not thrust
directly against washers, but apply a direct force against the clutch shoes.
If force is applied against the washers, it will restrict proper movement of
the clutch shoes.
12. Reinstall operator handle to engine and engine to transmission with
correct orientation to the operator handle. Throttle control of operator
handle goes on same side of engine with ON/OFF ignition switch and
same side of transmission cover that pressure relief valve is located.
13. Using 7/16 inch (12 mm) wrench, reinstall and tighten the four K-lock
nuts. Tighten nuts to an approximate 90 inch pound (10 N.m.) value. This
will place the nut flush with end of engine mounting stud.
NOTE: There is not adequate space to allow use of a conventional torque
wrench.
14. Rotate driveshaft and check for excessive noise and/or binding. If
excessive noise and/or binding is evident, disassemble engine from
transmission and investigate for probable causes. Reassemble and
retorque to the specified values. Recheck again for excessive noise
and/or binding.
15. Refill engine fuel tank and crankcase with appropriate fluids as required.

DANGER
• DO NOT smoke near fuel tank.
• DO NOT fill fuel tank with engine running or if it is hot.
• Allow ample time between each refueling for engine to
cool.
• An ignition source in close proximity to fuel tank can be
the source of an explosion, resulting in property damage
and/or personal injury.
• Consult material supplied by engine manufacturer for
information relative to proper fueling procedures.
DANGER
• Use safety type solvent.
• DO NOT use thinner, benzene, or other volatile solvents
that will attack rubber/plastic components when cleaning
Auger.
• Provide adequate ventilation.
• DO NOT smoke while using cleaning solvents.
• DO NOT use solvents with engine running or if it is hot.
• Allow ample time for engine to cool BEFORE using
solvents.
• An ignition source in close proximity to hot engine can be
the source of an explosion, resulting in property damage
and/or personal injury.
CAUTION
• Improper clutch and rotor shoe assembly orientation will result
in increased slippage and reduced digging capacity with
increased clutch wear.
CAUTION
• Improper shoulder bolt clearance will limit proper movement of
clutch shoes and overall operation.
• Such an occurrence can result in property damage and/or
personal injury.
WARNING
• Improper engine mounting orientation to transmission
can reduce machine control during hole digging process.
• Such an occurrence can result in property damage and/or
personal injury.
