REMARKS :
#
intake camshaft with for use with fixed pulley (like original exhaust)
--> The intake camshaft for use without vanos is slightly different from the exhaust camshaft. It is possible to use the original intake camshaft seal without further modifications.
--> for ordering, please use 23010xx instead of 22910xx from the VVT range (example: 2301013 = 2291013 but without VVT).
--> The cam trigger will need to be transferred from oem camshaft
#
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.
#
FOR COMPETITION APPLICATIONS ONLY. Following details must be verified:
-
the camshafs must turn smooth in the cylinderhead, provide free travel by machining where needed
-
distance between valve seal and retainer at full lift must be 0.6mm at least
-
minimum valve spring travel of 1.0mm at full lift must be provided
-
distance between valve and piston 1.0mm (pref. 1.5mm). check 5-15° before TDC on exhaust, and after TDC on intake

ONLY for use in competition engines with independent engine management (throttle position sensor) or carburettors
