To have access to the timing belt and crankshaft sprocket, it is necessary to first, strip the oil pan. Subsequently, take out the adjusting bar of the alternator and the bolt that fixes the bar to the oil pump. Take out the bolts of the power steering pump and unbolt it along with the hoses but without disconnecting them and set it aside, then removed the power steering pump bracket. Remove the oil pump to engine block bolts using the caution that you can leave the pickup tube and oil filter adapter connected to the pump if needed. Remove the oil pump gasket seal by striking it with a hammer having the tip of a block of wood on the top of the oil pump gasket seal, then, extract the oil pump from the engine block. Next, scrape and solvent the mating surfaces due to mating. For check, unscrew the bolt that is used to secure the rear cover of the oil pump to the pump, wash the components and check for wear and tear. The oil pressure regulator cap and washer, the spring and the valve should be removed and the condition of the sliding surface and of the spring should be carefully checked; as both the cap and washer, spring and valve are sold only as a complete set, since they are written off together. Using a feeler gauge check the calibration of the respective parts of the oil pump and if the clearance is high change the entire oil pump. Coat the pump in petroleum jelly to prepare the pump for moving the oil; fit the oil pump; and properly fasten the screws. Screw in the oil pressure regulator valve spring followed by the washer and the cap after it had been tightened. It is also recommended to change the O-ring on the flange of the pick-up tube oil and re-attach and tighten the bolts of the pick-up tube. To install, use ATV sealant on the surface that attaches to the oil pump, and replace any components that have been unbolted with new gaskets, and re-establish the reverse of the process of removal. Place the flats on the crankshaft to fit the flats on the oil pump gear, then tighten all bolts.
