In the factory valve setup, the valve clearance is set by cam followers of individual lengths.
Cat Cams offers two options to adjust the valve clearance:
1/ camshafts with factory cam base diameter of 38.2mm: use O.E.M. tappets with appropriate inner stud length to adjust the clearance. It may be required to replace the cam followers to obtain the correct valve clearance.
2/ camshafts with reduced cam base diameter to 35.0mm: use lash caps (dia. 6mm) with appropriate thickness to adjust the clearance
-
-> Please indicate the cam base diameter when ordering.
