IMPORTANT:
In the first generation mechanical 5cylinder 2 valve engines, two different distributor types have been used. Even if the distributor drive is not used, the cams are not interchangable. Please carefully read notes below to recognise which type of camshafts you have.
- 10020xx: the oldest type has a 13 teeth distributor drive gear. It is fitted at the end of the camshaft with a press fitting at 21mm distance from the thrustwasher (also last bearing).
- 10021xx: the most recent type has a 17 teeth distributor drive gear, which is also press fitted at the end of the camshafts, but directly against the thrustwasher (also last bearing).
Please indicate the type of intake camshaft you need when ordering and use the correct partnumber digits, corresponding with the correct type of camshaft. All camshafts are steel billet.
