Assembly ProcedureNotice In case the prechambers are reused, inspect the
prechambers thoroughly, if the ball pin by heat and fire is broken, it can not be used.
1. Clean the sealing surface of the prechamber.
2. Insert the prechamber into the cylinder head at the same time aligning the cam on the collar of the prechambers with the slots in the cylinder head. Notice If the spacer rings are fitted to the prechambers, the spacer rings should be replaced with rings of the same thickness.
Thickness of Spacer Ring 0.3, 0.6, 1.0 mm
3. Coat the threaded ring with oil and assemble the ring by using the serration wrench.
