303-01A-92 Engine – 2.5L Duratec-HE (122kW/165PS) - MI4 303-01A-92 ASSEMBLY 27.Rotate the crankshaft to confirm that there are no meshing problems between the balancer unit gear and the crankshaft gear. 28. ‡ Install the crankshaft TDC timing peg and rotate the crankshaft slowly clockwise until the crankshaft balance weight is up against the crankshaft TDC timing peg. Special Tool(s): 303-507 303-507 E131755 29.Remove the Special Tool(s): 303-507 303-507 E131755 30.NOTE: Measure the backlash and verify that it is within specified range at all of the following 6 positions: 10 degrees, 30 degrees, 100 degrees, 190 degrees, 210 degrees and 280 degrees. It will be necessary to reset the measuring equipment between measurements. NOTE: The measurement must be taken with the dial indicator gauge with holding fixture, a 5 mm allen wrench and worm clamp set up as shown. Mark the allen wrench with a file 80 mm (3.149 in) above the driven gear shaft center. Make sure the worm clamp and allen wrench are not touching the balance shaft housing. NOTE: For an accurate measurement while measuring the gear backlash, insert a screwdriver as shown into the crankshaft No. 1 crankweight area and set both the rotation and the thrust direction with the screwdriver, using a prying action as shown. ‡ Position the dial indicator gauge with holding fixture as shown. Measure the gear backlash. Special Tool(s): 100-002 ‡ Position the dial indicator gauge with holding fixture (1) on the allen wrench 80 mm (3.149 in) above the driven gear shaft center (2) on the balancer unit. ‡ Rotate the crankshaft clockwise and measure the backlash at all of the following 6 positions: 10 degrees, 30 degrees, 100 degrees, 190 degrees, 210 degrees and 280 degrees. ‡ Backlash specifications are 0.005 to 0.101 mm (0.00019 to 0.0039 in). ‡ If the backlash exceeds the specified range, carry out the balance shaft backlash procedure. Refer to: Balance Shaft Backlash (303-01 Engine - 2.5L Duratec-HE (122kW/165PS) - MI4, General Procedures). 1 E134654 31. CAUTION: Failure to position the No. 1 piston at TDC can result in damage to the engine. Turn the engine in the normal direction of rotation only.
