Oil Pump: Installation

  1. On turbo models, follow installation procedures under TIMING BELT & PULLEYS (TURBO MODELS)  . On all other models, align mark on camshaft with mark on No. 1 rocker arm shaft bracket. Align notch on crankshaft pulley with "O" mark on front cover. When 2 sets of marks are aligned, No. 4 piston is at TDC of compression stroke.
  2. Ensure that marks on oil pump inner and outer rotors are aligned. Engage oil pump drive gear with pinion gear on crankshaft, so that alignment mark is facing rearward, and away from crankshaft by approximately 20° in a clockwise direction. See Fig 1 .
