Flywheel Assembly Revisions On
1988-92 Toyota 4.0L Landcruiser Engines
Toyota has changed the flywheel assembly and crankshaft on 4.0L engines installed in the Landcruiser starting with the model produced in October of 1989. The revised engines carry an engine number of 3F-250226 or later.
The obvious difference between the former and the revised design is the flywheel bolts. Formerly these were 10x1.25mm bolts that were 32mm long. The revised bolts are 11x1.25mm and only 26mm long.
All of the components, including the crankshaft, are only interchangeable as a set. Be sure to verify the type of flywheel assembly and crankshaft that is being used when remanufacturing and installing Toyota 4.0L Landcruiser engines.
