TM 9-2350-247-34 REPLACE ENGINE (M548A3) — Continued 0008 00 CAUTION Damage to engine will result if crankshaft endplay is not complied with. Engines require a crankshaft endplay of not less than 0.004 inch nor more than 0.016 inch with new parts of 0.018 inch with used parts. NOTE The crankshaft endplay inspection must be completed without the transmission or front crankshaft pulley installed. 2. Hit the front of the crankshaft (1) two to three times with a large plastic mallet, driving the crankshaft (1) towards the rear of the engine or flywheel-housing end. Striking the crankshaft (1) will reduce the oil film on the thrust washers (4) and provide a more accurate reading. 3. Apply constant pressure on the crankshaft (1) towards the rear mount and position a magnetic base dial indicator or equivalent to the front bracket (3) – 8928723 on model 5063–539L engines. Then zero the dial indicator with dial indicator plunger on the crankshaft screw (2). 4. Position a small pry bar (less than 12 inches) between the front crankshaft washer (4) and the bracket (3). With the pry bar pull the crankshaft (1) towards the front of the engines. Keeping a constant pressure, record the crankshaft endplay. Engines require a crankshaft endplay of not less than 0.004 inch nor more than 0.0016 inches with new parts or 0.018 inch with used parts. 5. After the transmission has been mounted to the engine, repeat Steps 2 - 4 and record the crankshaft endplay reading. 6. Compare the crankshaft endplay readings, before and after transmission has been mounted to the engine. The recorded crankshaft endplay readings should not be different. 7. If the reading has changed, or reduced, then a binding or misalignment had occurred. The transmission mounting bolts should then be removed and the transmission (7) pulled away from the engine. The transmission (7) should then be remounted in alignment with the crankshaft and flywheel housing (8). After the second mounting, recheck the crankshaft endplay. 0008 00-12
