Dirt
Clean the engine thoroughly before servicing it. See following CAUTION.
Tightening Sequence
Where there is a tightening sequence indicated in this Service Manual, the bolts, nuts, or screws must be
tightened in the order and by the method indicated. When installing a part that is secured with several bolts,
nuts, or screws, hand tighten all, then tighten to specified torque in the proper sequence. This is to avoid dis-
tortion of the part and/or causing gas or oil leakage. Conversely, when loosening the bolts, nuts or screws,
loosen all about a quarter of a turn first and then remove them.
Torque
The torque values given in this Service Manual should always be adhered to. Applying too little or too much
torque may lead to serious damage.
Lubricant
Some oils and greases should only be used in certain applications and may be harmful if used in an applica-
tion for which they are not intended.
Lubrication
Engine wear is generally at its maximum while the engine is warming up and before all the rubbing surfaces
have adequate lubrication. During assembly, oil or grease (whichever is more suitable) should be applied to
any rubbing surface.
Press
A part installed using a press or driver, such as a seal, should first be coated with oil on its outer or inner cir-
cumference (contact surface) so that it will go into place smoothly.
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.
• BEFORE REMOVAL AND DISASSEMBLY, CLEAN THE ENGINE. ANY DIRT ENTERING THE
ENGINE, CARBURETOR, OR OTHER PARTS WILL WORK AS AN ABRASIVE AND SHORTEN
THE LIFE OF THE ENGINE. FOR THE SAME REASON, BEFORE INSTALLING A NEW PART,
CLEAN OFF ANY DUST OR METAL FILINGS.
