Oil Seal, Grease Seal
During assembly use new oil or grease seals to replace any that were removed, as removal generally dam-
ages seals. To avoid damaging the seal lips, a seal guide is required for installation. Before a shaft passes
through a seal, apply a small amount of lubricant (preferably high temperature grease) to the lip to reduce
rubber-to-metal friction.
Gasket, O-Ring
When in doubt as to the condition of a gasket or O-ring, replace it with a new one. To avoid leaks, the mating
surface around the gasket or O-rings should be free of foreign matter and perfectly smooth.
Liquid Gasket and Non-permanent Locking Agent
Follow manufacturer’s directions for cleaning and preparing surfaces where these compounds will be used.
Apply sparingly. Excessive amounts may block engine oil passages and cause serious damage.
Certain compounds can lead to premature gasket failure. Use the non-permanent locking agent Loctite
®
,
Lock’n Seal (Blue) or approved equivalent.
Ball Bearing Installation
When installing a ball bearing, the bearing race which has a press fit should be pushed by a suitable driver.
This prevents severe stress on the balls and races, and prevents damage. Press on the inner race if the ball
bearing is being pressed onto a shaft, or on the outer race if the ball bearing is being pressed into a housing.
Press the ball bearing until it is seated against the housing or on the shaft.
Circlip, Retaining Ring
Replace circlips and retaining rings that were removed with new circlips and retaining rings, as removal
weakens and deforms them. During installation, take care to compress or expand them only enough for
installation.
High Flash-point Solvent
To reduce fire danger a high flash-point solvent is recommended. A commercial solvent commonly available
in North America is Stoddard solvent (generic name). Always follow manufacturer and container directions
regarding the use of any solvent.
Molybdenum Disulfide (MoS
2
) Grease
NOTE: This manual makes reference to molybdenum disulfide grease in the assembly of certain engine and
chassis parts. Check manufacturer recommendations before using such special lubricants.
Engine Rotation
When turning the crankshaft by hand, always turn it clockwise as viewed from the clutch side of the engine.
This will ensure proper adjustments.
ELECTRICAL SYSTEM
See also Section 11 – Troubleshooting and Electrical System and Section 12 – Electrical Components.
1. Always minimize shock hazards when working on electrical equipment. Work in a clean, dry environ-
ment with dry hands.
