DIESEL BASIC SERVICE ENGINE DOWEL PIN DELETION

WHEN ORDERING 1980-81 DIESEL BASIC SERVICE ENGINES FROM GENERAL MOTORS WARE- HOUSING AND DISTRIBUTION DIVISION (GMWDD), IT WILL NO LONGER CONTAIN DWEL PINS ON THE CYLINDER HEADS AND GASKETS.

THEY SHOULD BE IN- STALLED IN THE NEW BLOCK IN THE SAME LOCATION AS IN THE ENGINE BEING REPLACED HOLES WILL BE PROVIDED IN THE SERVICE BLOCKS AT THE NECESSARY DOWEL PIN LOCATION POINTS. A NOTE WILL BE FORTHCOMING IN THE GMWDD PARTS BOOKS TO THIS EFFECT.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
