Front Crankshaft Seal: Service and Repair

Crankshaft Front Seal

















Removal

1. NOTICE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in the crankshaft pulley procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special tools, otherwise severe engine damage can occur.

Remove the crankshaft pulley. For additional information, refer to Crankshaft Pulley Service and Repair.

2. NOTICE: Use care not to damage the engine front cover or the crankshaft when removing the seal, or oil leakage may occur.

Using the Seal Remover, remove the crankshaft front seal.

1. NOTE: Lubricate the new crankshaft front seal with clean engine oil prior to installation.

Using the Crankshaft Front Oil Seal Installer, install the crankshaft front seal.





2. Install the crankshaft pulley. For additional information, refer to Crankshaft Pulley Service and Repair.
