Compression Ratio Limiting Shimming System:
(11-12:1)
1. Measure
«A»
(with piston at T.D.C.).
Note:
Measure «A» must be taken without any gasket installed between the crankcase and the
cylinder and after resetting the comparator, complete with support, on a rectified surface.
2. Install according to the measure
«A»
taken.
Note:
The «A» value to be measured is referred to the piston recess. It indicates the amount
by which the surface formed by the piston crown lowers, compared to the surface formed by
the cylinder upper part. The more the piston descends into the cylinder, the less the base
gasket to be applied (to recover the compression ratio) will be and vice versa.
