  Q: How Can Rod Bearing Caps Be Marked and Assembled for Accurate Installation on Chrysler Crossfire?

  A:

  Because the bearing caps on a Harley are not all the same, they should be marked on removal so you assemble them correctly. With the bearing shell, the tang should be placed in the machined groove of the rod and cap and the cap should have the tang on the same side as the rod. Add every crankshaft rod to one side of the engine before moving on and follow the required standards for taper and out-round on any crankshaft journal at 0.0006 in. (0.015 mm). Bearings are available in normal, smaller and smaller than that size and two bearings are needed for each rod; do not attempt to mix new and old bearings and do not try to file either the rods or the bearing caps. To tell how much clearance is needed between the main and connecting rod bearings, use plastigage measurement. Before you reuse connecting rod bolts, check them for stretching. If the threads are reduced, change them. If the threads just aren't evenly touching the edge of a scale, you must get a different bolt. Later, tighten the rod bolts in accordance with the specifications given.

  Q: How to measure Rod Bearing Clearances with Plastigage on Chrysler Crossfire?

  A:

  To measure the clearance on engine crankshaft bearings, use the Plastigage method after removing any oil from the surface of the bearing, since Plastigage will be dissolved by oil. Apply a piece of Plastigage across the bearing shell in the cap close to the middle but away from the oil holes and move it to the areas you think need checking. Fit the bearing cap bolts as required, then lift off the cap and check the width of the used Plastigage against the connected metric scale in the package to find the clearance in thousandths of a millimeter. Note every reading and compare it to the engine specifications listed in the manual. Plastigage should have both inch and metric scales. Just choose the type that matches your clearance requirements for a given part. After that, add the suitable crankshaft bearings to reach the given bearing clearances.
