    Rear Crankshaft Oil Seal Leak On
    1992-1994 4BD2TC GM Diesel Engines

    The AERA Technical Committee offers the following information for rear crankshaft oil seal leaks on 1992-94 4BD2TC GM diesel engines*. This four cylinder turbocharged diesel engine is used in GMC and Chevrolet W4 model trucks. If this leaking condition can be verified as coming from the rear main seal, installing a revised oil seal may resolve the leak.

    The installed position of this seal, Part #97072823, is critical to assure an effective seal. When correctly installed, the seal depth should be .445-.468 (11.3-11.98 mm) below the rear face or the crankshaft. The use of tool number J41269 (Figure 2) is also advised to minimize seal distortion during installation.

    Trucks that are equiped with an automatic transmission require the removal of the pilot bushing before installing a new seal. After installing the new seal, install the flywheel/flexplate and torque the mounting bolts to 115 ft. lbs.

    * This engine is built for GM by Isuzu Motors.
