Cylinder Block Assembly: Notes

The light aluminum alloy cylinders are very sensitive to damage and scratches, as well as contamination. The cylinders should therefore be handled very carefully. When honing, the cylinder bores must be adapted to the dimensions of available repair stage pistons with group No. 1 or 2. The specified piston clearance must be observed.

In the event of excessive scoring and heavy cylinder wear, the cylinders can be machine bored (if the proper procedures are used). Upon re-boring or honing, be sure to apply "silicone-lapping" according to the "Sunnen" method, to expose the silicone crystals.
