Injection pump

102. Fit the crankcase breather and the hand starter where applicable. NOTE! After fitting the hand starter, check that there is backlash between its gearwheel and the drive on the camshaft (in the case of MD17, the check is made through the cover on the hand starter.) If there is no clearance, the number of gaskets under the hand starter is increased until a noticeable clearance is obtained. 104A. Clean the mating surfaces on the pump and the timing gear cover. Remove the plastic foil from the new gasket and place the gasket on the cover. B. Measure the distance from the timing gear cover to the base circle of the pump cam (the cam should be turned towards the crankshaft). It is important that the distance should be 82.8±0.2 mm (3.26"±0.008") inclusive of gasket to ensure correct injection angle setting. If the distance is too small increase the number of gaskets. Each gasket is 0.20 mm (0.0079" thick). If the distance is too great, larger rollers must be fitted to the pump element lifters. These rollers are available in sizes differing by 0.12 mm (0.0047") in diameter. NOTE! If a pump has rollers of different sizes, the diameter of each roller should be increased by the same amount.

105. Remove the inspection cover on the timing gear cover and fit the injection pump. Make sure that the pin on the control rod is correctly fitted in the governor lever.

103. MD11: Fit the inspection covers on the crankcase. MD17: Fit the oil strainer. NOTE! Oil the sealing rings and place them on the ends of the pipe as shown in the illustration. Press the oil pipe into the strainer housing first and then into the crankcase. Fit the oil sump. Tighten the plug “1” (on certain engines).
