diesel engine give good service provided that the fuel is clean and with no air in the system
the problem can be air in the fuel lines to the pump, blocked filters , vent problem at the tank.
diesel fuel suffers from a moss growth in the fuel tanks which blocks the filters and can cause injector tip problems
As the engine starts and runs I would change the fuel filter and bleed all the air out for a starter
you may also drain the water trap under the filter or in the water separator filter before the filter
If you see evidence of the moss ( brown slimy looking substance in the filters ) use a good quality diesel fuel conditioner to kill it off
Hi Ken:
If it's overheating then the water pump and / or the fan are not turning. Should be quite straightforward to replace, especially if you have the broken one to match for the new one.
if the bobcat starts and then runs for a short time then dies the first place to look is the fuel system.fuel filters are the most common problems that i see replace those first.i have also found some junk inside the pickup tube inside the tank.there is probably a ball type hand pump to prime the fuel system.give that a squeeze and see if its hard.if thats the case there shoud be a small screw on top of the fuel filter.loosen that screw and see if fuel comes out when you sqeeze the ball.if your changing fuel filters this is also where you blead air from the system,keep pumping untill there is only fuel and no air.if you still get air after pumping for a long time then your sucking air into the system between the tank and pump.after you get fuel there close the screw,loosen the injector lines going to the injectors,crank the engine,and tighten when fuel comes out (keep clear because that is high pressure fuel).after you get fuel at all injectors and they are all tightened it should start.
Sir,
If you did a clean perfectly clean installation when installing the water pump,there should be no issues with air infiltration. If you are good , OK.
The most common problem over the years that can become an oversight for those around me is how clean the radiators core on the outside are..
Withstanding a change of the fluids and the filters when the pump went together.
Since this is a hydrostatic transmission. The other place that comes to mind is the transmission cooler that is in the loop area. What do say?
Well, a generous soaking of GUNK and or equivalent followed by a extensive pressure wash could make you very happy. Any way you will probably want it running when doing the total wash. We do.
It always made us smile. Here is to a happy chin, soon, too. Take a look. Fare well.
so the pump is weak, due to it is, or regulator or filters clogged
what you have there on the supply side, who knows that?
my guess is , not reading the kabuto engine spec on fuel pressure
and is wrong.. lift pumps too.
start from the geginning. fuel tank- trash water etc. fuel line, valve open line not plugged, caberator clean and float not stuck closed. use air to blow lines out. good luck
Oil cooler on that machine is for hydraulic oil. Is your fault for engine oil psi or charge psi? Charge psi unlocks brakes. Premature engine oil breaking down check for fuel in engine oil through lift pump or injection pump.
