850-029   ISX, QSX Static Timing Wedge

NOTE: For nominal timing values not available, use wedges to measure timing.

NOTE: For CM871 engines experiencing performance symptoms such as premature oil filter plugging, white smoke, and shellac, suggested tolerance from nominal measured timing is ± 0.003". For all others, it is ± 0.006".

NOTE: CPL's for single camshaft ISX15 CM2250 engines are not contained in this document because injection timing is not set with wedges; however, please note that all ISX valve camshafts are timed with a 6 degree wedge including single camshaft CPL's not listed.
