#
- steel billet camshafts
#
The XU9J4 (longtitudinal) and XU10J4 (tranversal) engines have different inlet camshafts due to servo pump drive setup. Therefore, the XU9J4 and XU10J4 engines are listed separately with a separate partnumber range
a) no drives on inlet camshaft (only in XU9J4 engine)
b) the camshaft has a central drive hole on both sides as the servo pump is belt driven (only in XU9J4 engine)
c) the servo pump is fitted on the inlet camshaft and driven by a sleeve. The lubrication of the pump is provided through the last bearing. This execution is only used in transversal engines (only in XU10J4 engine)
#
If the camshaft has a position encoder for the engine management system, it must be fitted on the new camshaft in the same position
#
machining of cylinder head can be required at camlobes
#
ONLY for dirt track applications and pro street use with adjustable engine management or carburettors
