# NEW TIMING BELT PARTS-PROPER INSTALLATION & SPECIFICATIONS

EFFECTIVE WITH 1985 PRODUCTION, THE "T" SERIES 1.6L L4 ENGINE WILL USE A NEW "ONE-PIECE" TIMING BELT SPROCKET AND SPACER. THE NEW "ONE-PIECE" SPROCKET AND SPACER WILL BE AVAILABLE IN A SERVICE KIT, P/N 14090950, FROM WDDGM. THIS KIT SHOULD ALSO BE USED TO SERVICE 1977 THRU 1984 MODELS. THE KIT WILL CONTAIN A SPROCKET AND SPACER, P/N 14076378, BOLT, P/N 14076332, AND A LABEL, P/N 14076356. THE REPLACEMENT PROCEDURES ARE COVERED IN THE 1985 "T" SERIES SHOP MANUAL, SECTION 6A1. CAUTION: WHEN THE FRONT COVER IS INSTALLED, ALIGNING TOOL J-26434 MUST BE USED TO PROPERLY CENTER THE COVER SEAL ON THE CRANKSHAFT. FAILURE TO USE THIS TOOL MAY RESULT IN A SUBSEQUENT OIL LEAK. TO ENSURE THAT THE THREADS OF THE CRANKSHAFT PULLEY BOLT HOLE ARE NOT DAMAGED WHILE DRILLING A BROKEN BOLT, THE USE OF A DRILL GUIDE, J-34984-2 IS RECOMMENDED. A DOWEL PIN WASHER, J-34984-3 IS REQUIRED TO ENSURE THAT THE DOWEL PINS ARE NOT DAMAGED DURING INSTALLATION OF THE SPROCKET AND SPACER. FAILURE TO APPLY 90 TO 100 FOOT POUNDS OF TORQUE TO THE CRANKSHAFT PULLEY BOLT MAY CAUSE A FAILURE OF BOLT AND/OR PULLEY. THIS WILL REQUIRE HOLDING THE CRANKSHAFT TO PREVENT ITS ROTATION WHILE TIGHTENING THE BOLT.

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.
