Lubrication Supply engine oil as specified even for a short test running to avoid any score which may destroy the engine in the field use. Use clean engine oil in the case specified as just “coat oil” in this manual. Don’ t use just any greases applications and may be harmful if used in an application for which they are not intended. Engine wear engine surfaces have an adequate lubricative film. During assembly, oil or grease (whichever should be applied to any rubbing surface which has

lost its lubricative film. Old grease and dirty oil

GENERAL

Force Common sense should dictate how much force

sary in assembly and disassembly. especially difficult to remove check what may be causing the problem. Whenever tapping

is

necessary, tap lightly using a wooden or plastic-faced mallet. Use an impact driver for screws (particularly for the removal of screws held by a locking agent) in order to avoid damaging the heads.

Press

A

part, such as a seal, installed using a press or

driver should first be coated with oil on

.or inner surface

smoothly.

Ball Bearing Installation When installing a ball bearing, the bearing race which

is

affected by friction should be pushed by a

suitable driver. This prevents severe stress on the

balls and races, and prevents races and balls from

being dented. Press a ball bearing until it stops
