INFORMATION ABOUT OVERHAULING
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
Important
•
Tab. 8.2a details the dimensional values of new
components only.

8.2.5 Camshaft control for 4 cylinder engine
With a micrometer, measure the maximum dimensions of intake
camshaft R and exhaust camshaft S (Tab. 8.2b).
The MAX value of wear allowed is 0.1 mm.
