    Pump arrived with surface corrosion/rust

    Pump arrived with surface corrosion/rust
    In years of ordering parts online and in-store this is the first time I've had a part arrive with a hefty amount of surface rust. I don't expect much, but I expect new parts to be clean. The internals appear to be unaffected, but some corrosion has bled over onto the mating surface and the impeller shaft. The impeller shaft is the only part that appears to have suffered minor metal loss, though it might be salvageable.

    5.0 out of 5 stars All Hail The Pump (the gasket was damaged by a hateful pump) RESOLVED!
    Reviewed in the United States on March 2, 2021
    Verified Purchase
    The pump is solid and it pumps oil just like it should by why is it so pumpous? Why the manufacturer insists on placing the gasket inside the box unprotected is lost on me. Like many others mine was cut during the shipping journey in all the areas that count. Because the pump is loosely packed inside the box with the lowly gasket tossed in beside it - the mounting flange's sharp edges on the pump hacked it up.

    **I contacted the seller who promptly resolved the situation** (pumptly and without hesitation - this is key)

    The media could not be loaded.
     The oil pressure on my 2.5L 1992 Jeep YJ has been worrisome for a years now, hot idle was dropping to 10 psi, decided to try installing a new oil pump before sending the old girl the the junkyard, the new oil pump and switching to Rotella 15w40 has brought the oil pressure back to what it was when I purchased the Jeep in 1997, cold idle is 60 psi and hot idle is 40 psi. This Jeep has seen lot of abuse and some times I haven't changed the oil for years, but the bearings are still good enough to develop 40 psi.

    5.0 out of 5 stars O.E. PUMP DESIGN PROPER FIT
    Reviewed in the United States on September 18, 2020
    Verified Purchase
    While addressing oil leak issues in our '99 Cherokee. I decided to change the original oil pump at 280,000 miles. This pump is the closest to factory, there are high volume pumps offered that do not fit unless you hammer out the oil pan which bends your sealing flange creating a potential oil leak. The old one had a bit of play between the gears but pumped 50lbs cold idle 25 lbs hot idle. The new pump is 60lbs cold idle 35lbs hot idle 45-50 at 2000 rpm on the road. I am happy with that. Jeep 4.0 liter motors do not have oil pump problems only the ones in owners heads. I replaced mine because it had to be removed along with the crankshaft truss to access the rear main seal.

    5.0 out of 5 stars Great but may need MCAT-62 tool for the screen tube
    Reviewed in the United States on October 23, 2015
    Verified Purchase
    If you are doing this yourself you may need the MCAT-62 tool and a 2lb sledge hammer to force (with delicate precision) the fragile oil screen pick up tube that is inserted into this pump. The tool is not cheap so something to consider adding to your cart and budget along with the oil screen or find a mechanic with the MCAT-62 tool and a 2 LB sledge hammer.
    Connect tool to screen tube, Align tube to pump on rubber floor or workbench (not in a vise), small taps on the tool.... Everything goes together very well with the MCAT-62 tool, but without it... Well.. I wish you the best of luck inserting the over sized screen tube (5/8") into this pump without damage to yourself or to the tube. FYI Heet (methyl alcohol; yellow bottle) and dry ice (poor man's liquid nitrogen) did not get the screen tube cold enough to shrink and fit into the pump in case you are thinking along that path.

    5.0 out of 5 stars Excellent product and I have yet to have any problems
    Reviewed in the United States on March 20, 2018
    Verified Purchase
    Replaced oil pump while replacing rear main seal on my Jeep Cherokee. Oil pressure went from ~20 PSI hot idle and ~40 PSI hot driving to 35-40 PSI hot idle and 60-65 PSI hot driving. Excellent product and I have yet to have any problems. Easy install if you're already removing your oil pan.

    P.S. If replacing your oil pump, I recommend priming the oil system before full starting your engine. This is done my removing the distributor or CPMS on distributor-less systems and spinning the oil pump gear with a flat head bit on a electric drill.

    5.0 out of 5 stars Oil Pump
    Reviewed in the United States on February 18, 2020
    Verified Purchase
    Melling is a high quality part, cast iron body , factory pump is aluminum which has a life span in the 150K range, which was putting out 0 oil pressure after engine is hot, now puts out about 20 lbs when hot. If I was going to do it again I would buy the high volume Melling, just because. But it is satisfactory, on Jeeps while the oil pan is removed replace the timing chain at the same time it will save you time and money in the long run.
