    Cat 931/3204 Fuel Delivery Pump Model

    GOOD ADVICE on the copper gaskets.. The inlet and hp are some real odd sizes.. NORMALLY u could go to your copper gasket box and grab a couple.. but not this size.. I’ve been trying for 40 years to find “extras” & it’s a no-go.. I think they did that purposely so u would HAVE TO buy a kit.??

    Case 580B 188 diesel, starts but immediately goes to very high rpms. What could cause it?

    It sounds as if someone knocked out the checkball return fitting, which allowed the bits of broken “flex ring” to return to the tank without shutting the engine down.. SO NOW, you’re banging metal to metal and about to shear off the metal pins on the weight retainer.. THAT will give u a...

    Case 580C running issues

    Happy to help.. Outlaw> did u transfer the timing line from your old weight retainer to the new one.?? Even if u did, it’s not going to be exact, like it should be.. We have a degree tool the ensures the mark is exact.. So trying to set the timing using the “timing lines” that you made and the...

    Cat 931/3204 Fuel Delivery Pump Model

    That piece is a straight fitting, sealed with either an oring or copper gasket.. It will unscrew with your fingers.. Coffmans pump has a roller that rides on the cam and I think Tyler’s has a rod.??

    They can be rebuilt.. new valves and springs and new seats cut.. even the main spring and piston can be replaced.. Have u checked the screen in the inlet banjo bolt.??

    New Holland skid steer with N-844 Shibaura engine governor adjustment

    You’re looking for 6psi at full load.. The thing about the supply pump is, it will read fine at low idle and part throttle but it can’t keep up the demand at full load.. THATS where a gauge comes in very handy.. The only thing u can tell by pulling the cover off is, if its rusted.. I’m assuming...

    New Holland skid steer with N-844 Shibaura engine governor adjustment

    Personally I would either put a psi gauge off the filter head or just replace the supply/lift pump… Have u made sure your getting full travel on the throttle lever.? Make sure it’s hitting the stop screw.. I don’t think u have to start the engine for that test..

    Leaky Fuel Rail on my 580c

    They don’t give a “pressure”spec.. they do give a return “flow” in cc’s.. taken off the top of the pump at full load speed.

    50s Continental TD427 injection pump problem(s)

    What r u going to do about the seized head and rotor.?? U can tell what caused it to seize by the score mark around the rotor.. The pump manufacturer has made a list with pictures.. Good luck with the overhaul..

    Case 580C running issues

    SOMEONE give this kid a RoosaMaster rebuild manual, PLEASE.!! Take the “HONE” word out of your vocabulary.. If the plungers won’t pass from side to side.. coat ONE in 38-1200 lapping compound and push it in. Now get 2 punches that just fit in the bore and move the piston from side to side .. It...

    Case 580C running issues

    U don’t hone the bore.. U put lapping compound on a piston and work it back and forth.. then do the other piston.. More than likely it has goo on it and just needs to be cleaned.. Did u check the metering valve.?? THAT HAS TO BE FREE..
