  Q: What Precautions Should Be Taken When Fitting Rod Bearings on One Bank on Chrysler Prowler?

  A:

  Put all the rods on one side and mark the caps as you remove them, since once you take them off you can't put them back in the wrong place. Take a bearing shell and fit the tangs into the machined grooves of the rods and caps, then put on the cap so that the tangs on both parts match. Don't allow more than 0.015 mm (0.0006 in.) of taper or out-of-round on the journal bores; use bearings with 0.025 mm (0.001 in.) and 0.254 mm (0.010 in.) undersized bore. Never install a new half bearing with an old half and never file the bearing caps or the rods. Wrap Plastigage around the connecting rod as you rotate the crankshaft with the rod at the lowest point and without its cap, then wipe off the journal with clean rag. Apply a length of Plastigage the length of the bearing shell inside the bearing cap, placing it 1/4 inch from the center away from the oil hole and reassemble the connecting rod cap without crankshaft rotation. Limply tighten the nuts on the connecting rod cap to 54 Nm (40 ft. lbs.) excluding the last 1/4 turn until the end of the build. Next, remove the bearing cap and compare the plastic ring you used with the markings on the plastigage for its width to determine oil clearance. Because necking can occur in connecting rod bolts, check for it before reusing and discard the bolts if necked. Check the threads by touching them with a scale; if you don't touch all of the threads, replace the bolt. Apply engine oil to the threads before installing the nuts by hand; afterwards, evenly tighten all the nuts in an ordering sequence. For connecting rod side clearance, place a dial indicator on a fixed point of the engine and align the probe with and touching, the connecting rod cap. Adjust the connecting rod to the back of its stroke, set the indication to zero and move it to the front and read the dial. Do the same for all connecting rods as you turn the crankshaft around for access.
