C. Piston
1. Mark each piston to aid in reassembly.
2. Place a clean towel or rag into the crank-case to keep circlips and material from falling into the engine.
3. Remove piston pin clips, piston pins, and pistons.
D. Pick-up Coil Assembly
12. Cylinder head and Cam shafts
a. Install the new cylinder head gasket. Install the dowel pins and "O-rings". Locate the cam chain cavity cylinder seal with the tabs down.

2. Properly oil all mating engine and transmission parts and bearings during reassembly.
3. Circlip
D. Valve Spring and Lifters
1. Checking the valve springs
a. This engine uses two springs of different sizes to prevent valve float or surging. The valve spring specifications show the basic value characteristics.
b. Even though the spring is constructed of durable spring steel, it gradually loses
REMOUNTING ENGINE
1. Reverse the applicable removal steps to reinstall.
CAUTION: Always use new bolts in the drive shaft coupling.
2. Install and tighten the engine mounting bolts.
Engine mounting bolt torque:
8 mm bolt: 2.0 m-kg (14.5 ft-lb)
10 mm bolt: 4.2 m-kg (30.4 ft-lb)
12 mm bolt: 7.0 m-kg (50.6 ft-lb)
