| | FASTENER REPLACEMENT WARNING |
Replacement Warning On Connecting Rod & Flywheel Or Driveplate Fasteners
Certain Chrysler (American Motors Corporation) products use fasteners that must be replaced when reassembling the engine. In particular use caution when working on Eagle, Jeep and Renault engines.
The following chart outlines the replacement of connecting rod and flywheel or driveplate fasteners for Chrysler Eagle, Jeep and Renault engines if the engine was disassembled.
COMPONENT: Flywheel/Driveplate bolts
ENGINE TYPE: C2J, C3J, F3N, 843, A7L J8S, J7T, 2.46L, 2.8L, 4.2L, 5.9L
COMPONENT: Connecting rod bolts/nuts

Chrysler (AMC Renault) 1.7 & 2.0L (105 & 122 CID) Engines
The Chrysler (AMC Renault) 1.7 & 2.0L (105 & 122 CID) engines use
a puck with a replaceable pad to adjust the valve lash. With the
engine cold, the recommended valve lash for the intake valves is
.008 (.20mm) and .015 (.40mm) for the exhaust valves (Figure
1).
Setting the valve lash requires mounting the camshaft and
camshaft caps to the cylinder head. Using the sequence outlined
in the illustration (Figure 2), torque bolts #11 & 12 (6mm
diameter) to 7 lbs.ft. and the remaining bolts (8mm diameter) to
15 lbs.ft. Apply a small amount of RTV sealer on the parting
face of each end camshaft bearing cap before installation. This
will guard against external oil leaks.

395 & SB 36

Engine overheating and other causes that lead to warpage and
leaks may prompt more late model aluminum cylinder heads to start
appearing in machine shops. Care should be used in obtaining
correct machining specifications.
An unmachined cylinder head on the above subject engine is
allowed to have .020 removed according to Chrysler (AMC) before
it is considered to be scrap. In one particular case the dealer
organization told the machinist only .005 could be removed.
Many aluminum cylinder heads may be saved by following sound
straightening methods before machining, such as those suggested
in Straightening Aluminum Cylinder Heads, published by AERA and
sent to all members last year or those outlined in the 1982
Proceedings.

##END## | | CYLINDER HEAD SPECS. ON AMC/RENAULT 1.7L ENGINES | Cylinder Head Specifications on
Chrysler (AMC/Renault) 1.7 & 2.0L Engines
The following machining and installation specifications should be observed when remanufacturing cylinder heads used on Chrysler (AMC/Renault) 1.7 & 2.0L engines. These engines are used in AMC Alliance, Encore and GTA automobiles.
According to Renault the cylinder head thickness is 6.673 +/- .007 (169.5 +/- .2mm). The maximum acceptable warp of the cylinder head deck face is .002 (.05mm). The cylinder head should not be resurfaced. Both intake and exhaust valves should be recessed .031 - .043 (.8 - 1.1mm) below the deck face of the
cylinder head.
Use the following procedure when installing a remanufactured cylinder head.
1. Clean head bolt threads. Apply oil to the threads and underneath the
head of the bolt.
2. Position the cylinder head gasket and mount the cylinder head.
3. Install the cylinder head bolts and tighten all bolts in sequence to
22 lbs.ft. (see illustration below)
4. Tighten all bolts in sequence to 52 lbs.ft.
5. Wait at least 3 minutes, then loosen all bolts completely.
6. Tighten all bolts in sequence to 15 lbs.ft.
7. Turn all bolts in sequence by 123o +/- 2o.
