J 34853 Crankshaft Oil Seal Guide

1. Apply engine oil to a J 34853
2. Fit the J 34853 to the oil pump seal.

Important: Ensure that the oil seal lip is not turned out during oil pump installation.

3. Install the oil pump to the cylinder block.

Use the J 34853

4. Remove the J 34853



5. Apply Loctite® pipe sealant GM P/N 12346004 or the equivalent to the thread portion of the short oil pump mounting bolt (1) indicated.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

6. Install the oil pump mounting bolts (2) to the oil pump assembly.

Tighten
Tighten the oil pump mounting bolts to 11 N·m (97 lb in).




7. Install the rubber seal (2) between the oil pump (1) and the coolant pump (3).



8. Use a sharp knife in order to cut off the edge of the oil pump gasket if the edge of the gasket bulges out.

Verify that the edge is smooth and flush with the end faces of the pump case and the cylinder block.

9. Install the timing belt guide and the crankshaft timing gear.

Ensure that the concave side of the timing belt guide faces the oil pump.

10. Lock the crankshaft with a slotted screwdriver.
11. Secure the timing assembly with a crankshaft timing gear bolt.

Tighten
Tighten the crankshaft timing gear bolt to 110 N·m (81 lb ft).
