8.2.4 4-cylinder camshaft housing check
The camshaft housings only contain the timing system
side bushing Q.
Use an internal dial gauge to measure the diameters of
housings X - W - K - Y - Z.
With a micrometer, measure the diameters of gudgeon
pins X1 - W1 - K1 - Y1 - Z1 (Fig. 8.4). According to the
values measured, calculate the clearance between the
housing and gudgeon, which is to observe the values in
Tab. 8.2a.
The MAX value of wear allowed is 0.120 mm
