615 Service Manual
Contact may vary, but generally is approximately in the tooth centre, equi-spaced between root and tip. The
marking may be towards toe on some gears on both flanks, or marking crossed slightly i.e. towards toe on
convex flank and heel on concave flank or vice versa.
If, compared to the factory tooth contact, the contact appears as shown below, then corrective action should
be taken as follows:
6.1 ERROR 1: Pinion too far out of mesh
Convex flank
Contact further to
toe and tip than factory marking.
Concave flank
Contact further to heel and tip than factory marking.
ACTION: Recheck and decrease shims below pinion cartridge flange.
