Modification Of 5P1768 Pointer Assembly Necessary For Use On Some Fuel Injection Pump Housings{1253,0653}

Usage:

Fuel Injection Pump Housings For 3408 And 3412 Engines

The hole in the fuel injection pump housings for 3408 and 3412 Engines, which is used to hold the off-engine timing dimension pointer, has been moved.

The 7.14 mm (.281") diameter hole in the 5P1768 Pointer Assembly has been increased in diameter and moved to permit use on the earlier and current fuel injection pump housings.

For 5P1768 Pointer Assemblies currently in the field, drill the 7.14 mm (.281") diameter hole (see the illustration) with either an 8.5 mm drill or a 21/64 (.328") drill. This modification will permit use of the 5P1768 Pointer Assembly for off-engine timing dimension checks on both early and current fuel injection pump housings for 3408 and 3412 Engines.

Location of hole which must be made larger.
