DIESEL ENGINE
Connecting Rod Cap
1. Remove the connecting rod screws (1) from connecting rod cap.
2. Remove the connecting rod caps.
(When reassembling)
•Align the marks (a) with each other. (Face the marks toward the
injection pump.)
• Apply engine oil to the connecting rod screws and lightly screw it
in by hand, then tighten it to the specified torque.
If the connecting rod screw won’t be screwed in smoothly, clean
the threads.
If the connecting rod screw is still hard to screw in, replace it.
• When using the existing crank pin metal again, put tally marks on
the crank pin metal and the connecting rod in order to keep their
positioning.
• Fit the crank pin metal in place : its centrally groove side toward
the connecting rod, and the non-grooved side toward the cap.

Piston
1. Turn the flywheel and set a piston to the top dead center.
2. Pull out the piston upward by lightly tapping it from the bottom of
the crankcase with the grip of a hammer.
(When reassembling)
• Before inserting the piston into the cylinder, apply enough engine
oil to the cylinder.
• When inserting the piston into the cylinder, face the mark on the
connecting rod to the injection pump.
• Do not change the combination of cylinder and piston.
Make sure of the position of each piston by marking. For
example, mark “1” on the No. 1 position.
• When inserting the piston into the cylinder, place the gap of
the top ring on the opposite side of the combustion chamber
and stagger the gaps of the second ring and oil ring marking
a right angle from the gap of the top ring.
• Carefully insert the pistons using a piston ring compressor
(1). Otherwise, their chrome-plated section may be
scratched, causing trouble inside the liner.
