  27. 27. 27F- Engine 1. Rotate the crankshaft to align the engine No. 1 cylinder at the TDC (Top Dead Center) position. - Rotate the engine to align the marking line on "1, 4" side stamped on the periphery of the crankshaft pulley - Remove the rocker cover and make sure that the mark on the camshaft position sensor gear plate is align with the upper surface of the cylinder head. 2. Install the pump to the engine after fixed the plate to the pump gear. - Fix the plate to the pump, then install the gear to the pump shaft. - At installation, ensure that the convex part of the plate is aligned with the 2 marks on the side of the pump. Fit the flange bolt hole to the engine correctly then it is automatically adjusted the angle to the idler gear. Make sure the mark is aligned. Fuel supply pump remove and reinstall
  28. 28. 28F- Engine Install the fuel supply pump as above picture. Fix the 2 stud (e) to the cylinder block lower part. Put the pump (b) to the flange (d), and tighten them with bolts (a). After the gear (g) and the pump shaft has been assembled temporarily , put the gear and pump assembly in to the stud (e) and tighten them with bolt (f) and nut (c). Before put it in make sure that the gear and plunger rotational direction is correctly matched. Insert the O-ring (33161-52000) between the pump (b) and flange (d), then tighten the bolt (a) (11703-08303) and nut (h). c dO-RING 33161-52000 O-RING 33171-52000 b a ef g h Reassemble for fuel supply pump, plate and pump gear
