PEUGEOT Fuel Injection Pump Timing

  1. With pump mounting bolts loose, dial indicator attached to No. 4 cylinder exhaust valve, and engine at 0.28" (7 mm) BTDC, rotate injection pump body away from engine. See Peugeot Fuel Injection Pump Installation. 
  2. Using adapters (8.0117T, P, and S), install dial indicator to pump. Turn engine and locate BDC and TDC points on the dial indicator. At BDC, the pump dial indicator should have some preload.
  3. Zero the pump dial indicator at BDC. Bring piston No. 4 to TDC of compression stroke. Check zero point of engine dial indicator. Turn engine 90° in reverse. Recheck pump dial indicator.
  4. Turn engine in normal direction of rotation and bring No. 4 piston to 0.038" (.97 mm) BTDC for Non-Turbo models or 0.016" (.40 mm) BTDC for Turbo models.
  5. Rotate pump towards the engine until pump dial indicator indicates a pump lift of 0.020" (.50 mm). Tighten pump mounting bolts, front and rear.
  6. Check timing by rotating engine 2 turns in normal direction. Turn engine back approximately 90°. Rotate engine slowly in normal direction while watching pump dial indicator.
  7. Stop turning engine when indicator shows a lift of 0.020" (.50 mm). No. 4 piston should then be at 0.038" (.97 mm) BTDC for Non-Turbo models, and 0.016" (.40 mm) BTDC for Turbo models. If readjustment is necessary, rotate pump.
  8. Remove dial indicators and supports. Reinstall inspection plug with a new gasket. Install springs, washer and half cones of No. 4 exhaust valve and adjust clearance. Reinstall pipes, hoses and controls. Adjust cables and bleed fuel circuit.
