TM 5-3895-369-14(10) Determine main bearing clearance asfollows:(a)(b)(c)(d)(e)Install 14 bearings (1) in seven bearingcaps (2) and in cylinder block.Install seven bearing caps (2) and 14screws (3). Tighten screws 130 lb-ft(176 N-m).Measure and record main borediameters at position C. Maximumdiameter is 3.2720 in. (83.109 mm). Ifmeasurement exceeds limit, replacebearings. If measurement is still abovelimit, replace top bearing caps.Subtract position A (recorded in step [8]) from position C (C - A). Maximum clearance is 0.00475 in.(0.119 mm). If measurement exceeds limit, replace crankshaft.Remove 14 screws (3), seven bearing caps (2), and 14 bearings (1).C.Installation.(1)If removed, install seven piston coolingnozzles (16) in cylinder block (10).Do not apply grease on outer diameter ofbearing halves or damage may result tobearing halves, related bearing caps, andcrankshaft.(2)Lubricate six bottom rod bearinghalves (15), thrust bearing half (14),and six bottom bearing halves (13) on convexside only with general purpose grease.If top and bottom bearing halves areexchanged, damage could result tocrankshaft journals.(3)Install six bottom rod bearing halves (15) on connecting rods (8).(4)Install thrust bearing half (14) and six bottom bearing halves (13) on cylinder block (10).(5)Install key (12) in crankshaft (1).5-141
