Chrysler MD060517 Assembly Oil

You can Select Your Vehicle to check if MD060517 fits your vehicle.

Insert the rotor with the big chamfered surface to the side of the some pump body locating then the oil pressure relief valve spring. Subsequently, screw the pump cover and fasten the bolts up to the required torque. Pour a thin layer of RTV sealant on the pump you are going to join, then pull it down into place and turn it a little to make a sounding contact with the covering block. Before installing the pump in place, apply sealant to the threads of the retaining bolts, then tighten them in order to the prescribed torque and, when viewed through the distributor opening, the slot in the shaft of the oil pump should be aligned with the crankshaft. Lubricate a new O-ring which is then slipped into the oil pump pickup opening, the pickup must then be inserted into the pump followed by the bolts being tightened to the correct torque. For the 2.2 liter engines, fit and torque the brace bolt and in the same process torque the pickup brace bolt as well.

First, however, remove the timing belt and the oil sump of the engine. Subsequently, remove and strip off the sump gasket that is visible out of the cooperation. Remove the securing bolts of the timing cover by unscrewing and pull out the cover and such components as the oil pump, pick-up pipe, and filter. Last but not the least; refitting is done just in the opposite manner as we have seen in the removal process above.

To gain access to the 2.2L even better and the 2.5L oil pan, one has to un bolt and remove the oil pickup then un bolt and remove the oil pump. Then, undo the retaining bolts and then you can take off the oil pump cover. There are details as how to check the end play of the rotors with the help of the feeler gauge and the straightedge, whereby the measurement ought to be matched with the standard ones. Take off the outer rotor and check the thickness, installation of the rotor should be done with the large chamfered surface to face the pump body. After the rotors have cooled down, measure the run-out of the rotor in relation to the shaft using a dial indicator and compare your results with the manufacture's specifications. Examine the outer rotor and take measurements at the outer edge to obtain the outer rotor-to-body clearance and then compare that with standard measurements. Checking on the warpage of the oil pump cover through feeler gauge and straight edge in order to meet the predetermined criteria. It will be important to measure the oil pressure relief valve spring to ensure that it has the correct length as per manufacturer's specifications. Whenever any of the components is worn out over the mentioned limits, then the oil pump will be required to be swapped with a new one.

Use a feeler gauge and a straightedge to compare the measurement to the specifications.

To refit, reverse the removal steps, using a new front casing gasket and tightening the bolts to the specified torque, while being mindful of the different bolt lengths.

Unscrew the pressure relief valve plug to extract the spring and valve, ensuring the free length of the spring is 1.85 in (47 mm); if it is shorter, replace it, and confirm that the valve plunger slides smoothly.

Scrape off old gasket material and sealant from the oil pump and engine block mating surfaces, and clean them with lacquer thinner or acetone.

Coat the threads of the retaining bolts with sealant, then install and tighten them to the specified torque.

Secure the pump cover by tightening the bolts to the specified torque, align the flats in the rotor with those on the crankshaft when installing the pump, and then attach the timing chain cover, tightening the bolts to the required torque.

Remove the cotter pin and cup to extract the spring and oil pump relief valve from the pump housing, measuring the free length of the relief valve spring.
