TM 5-3805-261-34 ENGINE MAINTENANCE. (cont) 13-5. Crankshaft Main Bearings. (Sheet 10 of 12) INSPECTION (Intermediate Main Bearings) (cont) CAUTION When installing intermediate bearings in cylinder block, crankshaft must be rotated in OPPOSITE DIRECTION from normal engine rotation. Failure to follow this procedure could result in damage to block, crankshaft, or both. 4. Position two new upper inter- mediate main bearings (11, Figure 13-27) in cylinder block above crankshaft journal with bearing tab toward tab locator in block. 5. Rotate crankshaft and tool against two new upper inter- mediate bearings (11) to push bearings (11, Figure 13-29) into position. For this step, rotate crankshaft clockwise when engine is viewed from rear. 6. Cut two pieces of plastigage approximately 1-1/2 inches long and position one piece on inside surface of bearing (10) in each of two crankshaft bearing caps (9, Figure 13-30). CAUTION Arrow on bottom of bearing caps must face front of engine; number on cap must match bearing number on outside of cylinder block. Failure to follow this proce- dure could result in damage to equipment. 7. Position two items 10 and 9 as an assembly and plastigage under crankshaft journal, alining holes. 8. Coat four bolts (7) with clean engine oil and install finger tight. Figure 13-30. Figure 13- Figure 13- Go to Sheet 11 13-30
