MILLING OF PRECHAMBER SEALING SURFACE
1 Drift
2 Sleeve
3 Milling Cutter
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.
Thickness of spacers
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.
