Engine Reassembly

1. Attach the piston to the connecting rod, if removed, by

inserting the piston pin.

NOTE: The side of the connecting rod with the lettering on

the bearing faces the side of the piston the cap is

on. See Figure 8.10.

NOTE: The piston pin will only slide in from one side. After

sliding the piston pin in, insert the piston pin cap.

2. Install the piston rings on the piston.

NOTE: There is an anti-rotation pin in each piston ring

groove to prevent the end of a ring from getting

caught on a port. See Figure 8.11.

NOTE: When installing the piston rings, the ring gaps must

line up with the pins.

NOTE: The piston rings are symmetrical.

3. Lubricate the piston and cylinder wall with 10w30

motor oil.

4. Compress the piston rings and slide the cylinder over

the piston just enough to cover the piston rings.

See Figure 8.12.

NOTE: The side of the piston with the longer skirt face the

exhaust side of the cylinder.
