TM 5-3805-261-34 ENGINE MAINTENANCE. (cont) 13-5. Crankshaft Main Bearings. (Sheet 2 of 12) REMOVAL (Front, Center and Rear Main Bearings and Thrust Bearings) NOTE This task is divided into two sections: removal of front, center and rear main bearings and thrust bearings and removal of two intermediate main bearings. Each crankshaft bearing cap has a number and an arrow. The number indicates the cap’s location in the engine. It matches a number on the outside of the block, next to which the cap is to be installed. The caps are numbered in order, from front of cylinder block to rear. The arrow on each cap must point toward engine front. 1. Remove six bolts (1), washers (2) and three items 3 and 4 as an assembly (Figure 13-14). 2. Remove and discard lower half of three main bearings (4) from crankshaft bearing caps (3, Figure 13-15). 3. Install dial test indicator on clean, machined surface at bottom of cylinder block, fourth main bearing journal from front (Figure 13-16). 4. Adjust contact pin until it just touches the side edge of crankshaft journal. 5. Adjust dial face so indicator reads "zero." Figure 13-14. Figure 13-15. Figure 13-16. Go to Sheet 3 13-22
