Milling of the Prechamber Sealing Surface
Notice
The prechamber sealing surface may only be remachined
once with the cylinder head fitted. It is essential to adhere
to the specified projection ‘C’ of the prechamber of 7.6 -
8.1mm.
This ensures that the required clearance exists between
prechamber and piston crown with the piston in TDC. For
this reason, spacer rings should be inserted on remachined
sealing surfaces.
If a spacer ring is already fitted, or a marking is made on the
cylinder head, the cylinder head must be removed and size
‘C’ measured if further remachining is necessary on a
prechamber sealing surface.
