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
