| Isuzu Engine >> CRANKSHAFT CAUTION FOR 3.2L ISUZU ENGINES
Crankshaft Caution For
1996-2002 Isuzu 3.2L Engines
The AERA Technical Committee offers the following crankshaft caution for 1996-2002 Isuzu 3.2L engines. This caution is expressed to engine rebuilders when crankshaft replacement is required. This engine series has used two different crankshaft assemblies during the above mentioned time period. Intermixing those crankshafts may produce a no-start situation.
The difference in the crankshafts is in the diameter of the ignition reluctor wheel attached to between the 3rd and 4th rod journal. The measurement difference is only slight and may not be noticed if only visual comparison of the two crankshafts is made.
To determine which crankshaft you?re working on it is suggested to measure outside diameter of the reluctor wheel on the crankshaft and refer to the chart below.
Application Engine Model Reluctor Diameter OE Crank Part #
1996-97 ? 6VD1 6.937 (176.200 MM) 8971094432
1997 ? -2002 6VD1W 7.250 (184.150 MM) 8791318572
The difference, however, is enough to interrupt the ignition signal from the crankshaft to allow a no start condition. Changing the crankshaft out to is one method of correction and removing the old reluctor wheel and placing it on the replacement crankshaft is another.
