Number 87-6 (Gasoline)-29 Date 4/87Subject: SERVICE REPLACEMENT CRANKSHAFTS
1984-87 6000, FIREBIRD, PHOENIX, AND FIERO MODELS EQUIPPED WITH 2.5L ENGINES (VIN CODES R AND 2)
All service replacement crankshafts for 2.5L engines, codes R and 2, in 1984-87 vehicles are produced on current production tooling. All dimensions and specifications are identical.
The new crankshaft, part number 10044299, does, however, have the current production reluctor ring cast on the shaft. This ring has no effect on the installation or performance of the crankshaft when used on earlier 1984 thru 1986 engines.
