  Q: How to remove and install an oil pump in SOHC engine?

  A: Take out the Timing Belt, tensioner, crankshaft sprocket and belt guide. Pull the Oil Pan off and remove the oil pickup tube. Remove the alternator bracket. Undo dipstick tube bolts and take it out of engine front case. Take off front cover to block bolts and separate front cover from engine carefully. Disconnect cover from rear of case and remove inner/outer oil pump gears. Crankshaft oil seal must be removed from front case. Pressurizing valve retainer with plunger spring should be taken out too. Thoroughly clean all parts removing any trace of old gasket material on sealing surfaces .Visually examine these parts for wear ,cracks or other damage.Comparing parts as necessary.Installation of the outer and inner gears of the oil pump is followed by measuring their clearances.Comparisons between clearances and specifications are made.Measurement is done also on free height relief valve spring.Replacement should be made in areas where necessary.The pump cavity is then filled with petroleum jelly before installation of its cover.Its new crankshaft's front oil seal will then be replaced.Pressure relief valve components are installed.Finally,positioning the front cover using a new gasket.Bolts are put back in their original locations.On reversal order reinstall remaining parts.Add oil, start the engine, and Remember to check oil pressure and leaks.

  Q: How to remove and inspect an oil pump in DOHC engine?

  A: The Oil Pan is the first item to be removed, and then comes the oil pump pickup tube. Then, it is followed by removing of the oil pump sprocket cover bolts and detaching the sprocket cover. The chain guide nuts of the oil pump drive are loosened and pushed away from the chain a little bit to create some slack in it. Lastly, remove all of the mounting bolts holding down your pump before taking off its entire body or any other piece that might damage or hinder proper functioning. This will damage the center shaft in your oil pump if you try to separate it from your sprocket ring. For inspection purposes, this unit is taken apart whereupon every part gets cleaned thoroughly before being inspected for wear and tear cracks other damages. All parts should be replaced as necessary after being checked visually for wear, cracks, and other obvious signs of damage. This is followed by putting in place outer rotors of oil pumps whose clearance will later be measured between their peripheries and cases as well as from one rotor face to another using straightedges respectively. The free length of this spring must be measured on a flat metal surface such as a workbench or table before replacement if too short for purpose since relief valve spring has to be replaced when shortest possible than 1 inch for pressure regulation purposes on such pumps while still installed within system at time under them according some technical specifications typically used by various manufacturers such those contained herein. Lastly, petroleum jelly will fill up cavity while rotor faces go back into their spaces along with installation of rotors followed closely by fixing together two halves making housing complete when relief valve retainer also inserted which forms part comprising first figure shown below represents assembly line view for quick reference only-do not use these images unless explicitly stated otherwise.). Examination of excessive wear or damage should now take place using eyesight alone applied directly onto chains rollers attached between driver teeth plates; damaged unit could thus be replaced without needing to look further than that. Depending on the condition of the chain, it may need changing if worn or damaged in any way before removal from crankshaft becomes possible; this process alone requires removing crankshaft because it is now known as a unit with this inside and out. By carefully placing oil pump on block along accompanied by simple placement without tension, ensure that there's a provision for pump drive chain being supplied or installed while mounting completed above same block: through front side coincide onto its studs where lastly tightened. This is done by having an assistant pull the scale until the reading on it reached between 4.4 and 6.6 pounds of pressure when he pushes back so that your chain tightens itself up again with no more pulling required from his side whatsoever after which these nuts should be screwed down tightly against base posts holding shift lever housing's whole assembly right outwards just enough thereby allowing them touch each other always-never go too far apart!). You will then need to put back nut lock washer over bolt head leaving loose just like before then follow all other steps below secures lid securely tightening every screw onto pump housing back together after understanding what goes where, going ahead repair damages sealants or adhesive materials etc.; finally adding any remaining liquids into engine start run motor checking if there are no problems connected either directly related only those previously mentioned during discussion question about Leaks.).
