Tools Required
• | J 8037 Piston
Ring Compressor |
- Install the J 41742
onto the connecting rod hole which will
allow the guide pin to clear the crankshaft bearing bridge.
Only one J 41742
is required to properly align the connecting rod with crankshaft.
- Install the upper rod bearing to the rod.
- Coat the following components with Engine Oil Supplement (EOS),
GM P/N 1052367:
• | Coat the cylinder bore. |
• | Coat the bearing surfaces. |
- Perform the following
steps to install the piston:
4.1. | Position the piston with the arrow on the piston head facing toward
the front of the engine. |
4.2. | Use the J 8037
to compress the piston rings. |
4.3. | Place the piston in the cylinder (2). |
4.4. | Lightly tap the piston into the cylinder bore while an assistant
guides the connecting rod onto the crankshaft. |
- Remove the J 41742
.
- Perform the following steps to install the connecting rod caps
with bearings to the connecting rod:
6.1. | Install with the bumps on the connecting rod and the cap facing
toward the rear of the engine. |
6.2. | Coat the bearing surface with Engine Oil Supplement (EOS), GM P/N 1052367. |
- Use new connecting rod cap bolts.
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.
- Install the connecting
rod cap bolts.
Tighten
Tighten the connecting rod bearing cap bolts to 35 N·m
(26 lb ft).
- Use the J 36660-A
to rotate the main bearing cap bolts in the following sequence:
Tighten
- The first pass rotate the connecting rod bearing cap bolts 45
degrees.
- The second pass rotate the connecting rod bearing cap bolts 45
degrees.
- The third and final pass rotate the connecting rod bearing cap
bolts an additional 15 degrees.
- Repeat steps for the remaining pistons.
