Determining axial backlash of the cam-

shaft

z Push back the camshaft as far as it goes.

z Measure the camshaft stand back from the lay-on

surface on the camshaft gear wheel to the crankcase

with the depth measuring appliance (arrows).

z Note measured value, dimension (a).

z Mount new gasket (1).

z Measure the flange height from the running surfaces

to the lay-on surface with the depth measuring appli-

ance (arrows).

z Note measured value, dimension (b).

z Determine axial backlash.

Calculation example

Desired: Axial backlash

Given: -

Measured: (a) = 45.80 mm

(b) = 45.50 mm

Calculation: Axial backlash = dimension (a) - dimension (b)

45.80 mm - 45.50 mm

Result: =0.30mm

z Mount cover (2).

z Fit new sealing rings.

z Tighten all screws (1).
