Inspections and Measurements
With the liners out of the engine block, perform four
measurements, two on the upper part and two on the
lower part, turning the bore gauge 90° between them.
Check liners out-of-roundness, taper and waste.
Clean liner housing and install Tombak ring (A).
Measure liner protrusion in relation to the upper surface
of the engine block with a dial indicator gauge.
As a bracket to the dial indicator gauge, it can be
used the special tool MWM nr. 9.407.0.690.031.6.
If necessary, use a stainless steel ring underneath
Tombak ring to obtain the specified height.
The protrusion measurement must be performed on
the first step of the liner, at four positions at 90° each.
