CHARGING SYSTEM

A. Circuit Diagram

Above circuit diagram shows charging circuit in wiring diagram.

B. A.C. Generator

1. Checking method.

a.  Connect D.C. voltmeter to the battery terminals.

SHAFT DRIVE

Refer to "CHAPTER 3". for the middle gear.

The following special tools are not available but can be constructed for the final gear disassembly and assembly:

ENGINE ASSEMBLY AND ADJUSTMENT

A. Important Information

1.    Gasket and seal

All gaskets and seals should be replaced when an engine is overhauled. All gasket surfaces and oil seal lips must be cleaned.

2.    Properly oil all mating engine and transmission parts and bearings during reassembly.

3.    Circlip

CABLE ROUTING

LIGHTING SYSTEM

A. Circuit Diagram

Above circuit diagram shows only lighting circuit in wiring diagram.

B. Lighting Tests and Checks

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.

D. Remounting Engine

Refer to page 30 for engine removal. Reverse the applicable removal steps.

CAUTION:
Always use new bolts in the drive shaft coupling.

2. Install and tighten the engine mounting bolts.

F. Cylinder

1.    Inspect the cylinder walls for scratches. If vertical scratches are evident, the cylinder wall should be rebored or the cylinder should be replaced.

2.   Measure cylinder wall wear as shown. If wear is excessive, compression pressure will decrease. Rebore the cylinder wall and replace the piston and piston rings. Cylinder wear should be measured at three depths with a cylinder bore gauge. (See illustration.)
