Ford 7T4Z-6600-AA Pump Assembly - Oil

You can Select Your Vehicle to check if 7T4Z-6600-AA fits your vehicle.

The oil pump cannot be sub-assembled or internally examined; thus, the entire unit is worked on. On 2019 models, the oil pump is part of the balance shaft assembly and hence cannot be replaced independently of the other component. Start by removing the engine oil and also pulling out the oil filter out of the engine. The engine must be supported from above with the help of a support fixture. Subsequently, the timing chain cover needs to be taken off and all the bolts of the air compressor should be loosened while the compressor should be tied out of the way without the removal of the lines. Unbolt and take off the oil pan and the oil pick up tube which is installed through two mounting bolts. Using only a screwdriver, pull the tip of the oil pump drive chain tensioner spring out from beneath the shouldered bolt and then take out the two bolts and the tensioner. Remove the chain from the oil pump sprocket, using the appropriate tool, hold the oil pump drive sprocket to remove the sprocket bolt and finally, remove the sprocket. There are pump mounting bolts which must be unscrewed and then the pump. Installation is just the reverse of the removal and great care has to be taken to replace all the gaskets with new ones and tighten the mounting bolts of the oil pump to the recommended torque. Finally, after installing the oil pan it is recommended that a new oil filter be fitted and fresh oil be put into the crankcase. Lastly, look for any oil warning light in the instrument cluster, while the vehicle is running and idle.

On 3. SL engines, this operation can only be done when the engine is out of the car although one hopes that the new 3. All the steps that do not apply since SL engine has been removed should be completely disregarded. To start with, you should disconnect the oil pan, as well as the oil screen pick-up tube assembly. Then, take off the timing chain cover, timing chains, crankshaft sprockets and so on. Each of the four oil pump mounting bolts can be loosened one full turn before gradually and evenly turning each of the bolts many times. After all the bolts have been loosened, take out the bolts and the oil pump also, when doing this should rotate the oil housing in a clockwise direction in 3.5 L engines in order to detach the oil housing from the oil pickup tube. Continue to pull out the following parts; the oil pump cover should be detached from the pump body, the identification marks on the rotors noted as they are pulled out. Rinse and dry all related parts, which is to check the surface of the rotors for wear and or damage; if there is score mark or other sort of damage on rotors, pump body or cover, then it requires changing the entire oil pump assembly. If the components are acceptable, dip the rotors in clean engine oil and reassemble them to the pump body; make sure the identification mark fits as mentioned above. Screw the cover for added stability and proper fixing. For installation, turn the inner rotor of oil pump to the crankshaft where the flats are provided and place the pump over the crankshaft appropriately unto the cylinder block where it will engage with the block tightly. For 3.5 L engines, the pump assembly has to be rotated in anti-clockwise direction to locate the pump assembly near the O-ring of the oil pick up tube. Screw the oil pump bolts till they get tighten by hand and then using parallel pattern tighten up to the torque then tighten four by four sequence until the torque is met. The rest of the installation is a complete mirror image of the removal process outlined above. Last but not the least, replace the engine oil and add a fresh filter and start the engine, scanning for any signs of leaks.

Remove the oil pick-up tube, which is held by two mounting bolts.

Install the oil pump to the engine and tighten the bolts to the specified torque. Note: Prime the oil pump prior to installation by pouring clean oil into the pick-up port and turning the pump by hand.

Remove all traces of gasket material from the oil pump cover.

Note any identification marks on the rotors and withdraw the rotors from the pump body.

Remove the three oil pump mounting bolts and remove the oil pump.

Remove the oil pan.

Remove the oil pan.

Slide the crankshaft sprocket from the crankshaft.

The next action is to slide the crankshaft sprocket from the crankshaft.

Install the oil pump to the engine and tighten the bolts to the specified torque. Note: Prime the oil pump prior to installation by pouring clean oil into the pick-up port and turning the pump by hand.
