Connecting Rod Alignment

NOTE

• Make sure that the oil clearance of the small end bushing is

less than the allowable limit.

1. Install the piston pin into the connecting rod.

2. Install  the  connecting  rod  on  the  alignment  tool  of  the

connecting rod.

3. Put  a  gauge  on  the  piston  pin,  and  move  it  against  the  face

plate.

4. If the gauge does not touch fully against the face plate, measure

the space between the gauge pin and face plate.

5. If the measurement is more than the allowable limit, replace the

connecting rod.

Piston Ring Gap

1. Put the piston ring into the lower part of the liner (the least worn

out part) with the piston.

2. Measure the ring gap with a feeler gauge.

3. If the ring gap is more than the allowable limit, replace the ring.
