Crankshaft Bearing Installation Procedure

Note:If the crankshaft bearings have been used in a running engine, you must replace themwith NEW crankshaft bearings for reassembly.

Clean the crankcase crank bore with a lint-free cloth.Clean all the oil from the backside of new bearing halves.

Crankshaft and Bearing Installation Engine Block Cylinder Block Crankshaft

Install the NEW upper crankshaft bearings into position. The thrust bearing belongsin the number-3 journal. Ensure that the upper bearing insert contains the oil transferhole and groove. Roll the bearing into position so that the lock tang engages thecrank slot. The bearing must fit flush with the upper crankcase.

Place a length of fresh, room temperature plastic gaging material all the way acrossall the crankshaft bearing journals.Identify the proper order of the main bearing caps. The main bearing caps are numbered-1-(1)through-4, with the front main bearing cap marked with the number-1. The arrow-(2)is to be oriented to the front of the engine.

Tighten the main caps bolts using the EN 45059 meterin the following sequence:

Caution:Refer toFastener Caution.

Tighten the inboard bolts-(1–8) first, in two passes.Tighten the inboard bolts to 20-Y (15-lb-ft) on the first pass.Tighten the inboard bolts-(1–8) an additional 80-degrees on the 2nd pass.

Note:Do not rotate the crankshaft.

After reaching final torque, allow the assembly to sit for 2-minutes.

Determine the crankshaft bearing clearance by comparing the width of the flattenedplastic gaging material at its widest point with the graduation on the gaging materialcontainer.

Note:The crankshaft bearings CAN be reused after checking the clearance if the bearingshave never been used in a running engine.

Compare your measurements with theEngine Mechanical Specifications. If the new bearings do not provide the proper crankshaft to bearing clearance, inspectthe following:Re-measure the crankshaft journals for the correct specified size and ensure the propernew bearings are being installed. If the crankshaft journals are incorrectly sized,replace or regrind the crankshaft. Crankshaft machining is permitted and undersizedbearings are available.Re-measure the engine block crankshaft bearing bore diameter to ensure proper size.The engine block crankshaft bearing bore is not machinable and the block must be replacedif out of specification.Clean the plastic gaging material from the crankshaft bearing journals with a soft,lint-free cloth.
