  Q: How to replace the rear crankshaft seal on Chevrolet Venture?

  A: Before installing the Crankshaft rear oil seal the engine Flywheel must be detached with caution to protect the Crankshaft sealing surface. You must extract the Crankshaft rear oil seal by driving a flatbladed tool or comparable tool through its dust lip at a diagonal angle to push the seal out while moving the handle towards the Crankshaft end. The process should be repeated as needed. Before installation remove the safety sleeve from the new Crankshaft rear oil seal while avoiding contact with both the sealing lip and any oil lubrication on the seal or installer. Use a lint-free towel to clean the Crankshaft sealing surface before inspecting the lead-in edge for burrs or sharp edges that deserve removal using crocus cloth. Make note of the rear oil seal direction since the new style operates backward with "this side out" text marked on it. Put the Crankshaft rear oil seal inside the j 34686 rear main seal installer (J 34686) by moving it against the tool's collar through rotating the mandrel until complete seal insertion. Before tightening the screws on the j 34686 install it onto the Crankshaft's rear end to guarantee proper seal location. First tighten the j 34686 wing nut to completion then eliminate the tool before placing the engine Flywheel back in position.
