ENGINE OVERHAUL Inspection and Repair

SHAFT IDLE GEAR "C" AND IDLE GEAR "C" 

Make the necessary adjustments, repair and part replacements if excessive wear or damage is discovered during inspection. BRIDGE 

Inspect any cracking, damage on bridge and inspect any separation wear out and damage on the surface of bridge

1. Measure the outside outside diameter diameter of sha shaft ft idle idle gear “C”. Standard: 48.93 - 48.96 mm (1.9264 - 1.9286 in) in ) Limit: 48.85 mm (1.9232 in) 2. Measure the clearance clearance between the shaft shaft and idle idle gear "C". Standard: 0.04 - 0.105 mm (0.0016 - 0.0041 0.004 1 in) Limit: 0.2 mm (0.0079 in.)

SM7784

CLEARANCE BETWEEN CAMSHAFT

AND 

BRACKET 

Measure the clearance between the camshaft and camshaft bracket. Standard: 0.065 - 0.125 mm (0.0026 - 0.0049 in) in )

SM7786

VALVE SPRING 

1. Use a vernier vernier ca calmer lmer to m measure easure the the valve valve spring free height. If the measured value is less than the specified limit, the valve spring must be replaced. Valve spring free height Inlet spring:

Limit: 0.15 mm (0.0059 in)

Standard: 79.3 mm (3.122 in) Limit: 75.3 mm (2.965 in) Exhaust spring: outer Standard: 102.7 mm (4.0433 in) Limit: 97.6 mm (3.0843 in) Exhaust spring: inner Standard: 96.4 mm (3.0795 in) Limit: 91.7 mm (3.0610 in)
