Crankshaft Bushing Replacement
Bushing Removal
Remove the bushing from the housing (cylinder
block) using a bushing driving tool to prevent
damage.
Press-fitting the bushing
1. Prior to installing the bushing, inspect the
bushing housing for marks, scratches, etc.
2. The bushing should be smoothly pressed in to
the correct depth by using a bushing driving tool,
adjusting the oil hole and direction of bushing.
– Press in the bushing to the cylinder block
from the engine front side.
NOTE: Do not press in the bushing to the cylinder
block from the opposite side.
The correct pressing side is chamfered, etc.,
to allow smooth operation.
