WARNING: This page is about a different car, the 2002 GMC Savana and 2002 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
- Apply clean engine oil to the following components:
- The piston
- The piston rings
- The cylinder bore
- The bearing surfaces
- Install the J 5239 onto the connecting rod bolts.
- Install the J 8037
onto the piston and compress the piston rings.
Important: The mark on the top of the piston must face the front of the engine block.
When assembled, the flanges on the connecting rod and connecting rod cap should face to the front of the engine block on the left bank, and to the rear of the engine block on the right bank.
- Install the piston and connecting rod assembly, and the J 8037 into the proper cylinder bore.
- Use the J 8037
and the J 5239
and lightly tap the top of the piston with a wooden hammer handle.
- 5.1. Hold the J 8037 firmly against the engine block until all of the piston rings have entered the cylinder bore.
- 5.2. Use the J 5239 in order to guide the connecting rod onto the crankshaft journal.
- Remove the J 5239
.
NOTE: Refer to FASTENER NOTICE .
- Install the connecting rod caps, bearings, and nuts.
Tighten
- 7.1. Tighten the nuts evenly on the first pass to 27 N.m(20 lb ft).
- 7.2. Use the J 36660-A in order to tighten the nuts on the final pass an additional 70 degrees.
- After the piston and connecting rod assemblies have been installed, lightly tap each connecting rod assembly, parallel to the crankpin, in order to ensure that the connecting rods have side clearance.
- Use a feeler gage or a dial indicator to measure the connecting rod side clearance between the connecting rod caps. The connecting rod side clearance should be 0.15-0.44 mm (0.006-0.017 in).
