The pitch angle of the honing lines in the cross hatch pattern
should be about 30°, which is achieved by combining for
example 40 strokes/min with a rotational speed of 100 RPM.

As coolant a honing oil is preferred, but a light fuel oil 2-15
cSt could also be used.

After honing, the liner bore must be carefully cleaned by
using a suitable brush, water (preferably hot) and soap or
cleaning fluid, alternatively, light fuel oil. Then dry with a
cloth and lubricate with engine oil for corrosion protection.
The honing equipment 800008 is delivered with the engine.
b) Check the inner diameter
of the cylinder liner.
c) Cleaning of the cylinder liner cooling bores
The cooling bores in the collar can be cleaned by boring with a
suitable drill (ø 9.5 - 10 mm).
