1 Use feeler gauge to check the throttle clearance.
Attention· Make sure to measure the clearance between
basic circle of cam and valve adjusting gasket.
Standard of valve clearance :
IN 0.18±0.05
valve
spacing
EX
0.25±0.05
2 When it is beyond the benchmark value, the
adjustment washer has to be replaced and the clearance
should be adjusted.
Attention The valve number that goes beyond the
benchmark value has to be recorded, and the result of
measurements should be recorded as well
(1) Use a caliper to measure and adjust the thickness of
the separation cushion.
2.18 2.40 2.62
2.20 2.42 2.64
2.22 2.44 2.66
2.24 2.46 2.68

2.34 2.56 2.78
2.32 2.54 2.76
2.38 2.60
(2)Select proper separation cushion on the basis of the
throttle thrusting rod benchmark values.
① IN
Selected cushion thickness = removed cushion
thickness + (measured throttle spacing – 0.18mm)
EX②
Selected cushion thickness = removed cushion
thickness + (measured throttle spacing –
0.25mm）
