Disassembly Note
Connecting rod cap
1. Before removing the connecting rod caps, measure the con-
necting rod side clearance. (Refer to page Bl-73.)
Connecting rod
1. Before removing the connecting rods, measure the connect-
ing rod oil clearance. (Refer to page Bl-73.)
2. Remove the Plastigage from the crankpin journals.
Caution
l Do not scratch the crankshaft journal or the cylin-
der wall.
3. Use the handle of a hammer to remove the piston and con-
necting rod assembly through the top of the cylinder block.
Piston ring
Caution
l Do not apply excessive tension, which may cause
the rings to snap out.
1. Remove the piston rings with a piston ring expander (com-
mercially available).
Piston pin
Caution
l Mark the connecting rod direction for proper reas-
sembly.
1. Before disassembling the piston and connecting rod, check
the oscillation torque as shown.
If the large end does not drop by its own weight, replace
the piston or the piston pin.
