How do you tell if the injection pump is going bad-on my ford 601 workmaster tractor--4 cylinder diesel?

3 cylinder Perkin diesels were used for a long period of time in MF units
the mPN is HTS0391- alternate numbers -3639020M1
any accredited diesel specialist shop will be able to get you one or be able to repair and recalibrate your unit
you can mention that it is out of a MF tractor but the details that you want are a 3 cylinder Perkins engine
The original brand is CAV but there are other makes available

Diesel in petrol car This is far less common as the diesel nozzle is physically larger than the petrol filler neck on most cars.

Do not turn over the engine!

Diesel in petrol can cause serious damage - particularly to direct injection (GDI) petrol engines.

You will need to flush the fuel tank and the fuel line system.

You need to ensure that here are no vacuum leaks in the line from the tank to the lift pump, the lift pump which looks very similar to a car petrol pump must be in good working order ie able to pump the minimum pressure and volume at cranking speed and idle speed.
If the lift pump is not working properly it will cause cavitation at the injector pump that will cause low pressure bubbles on the intake of the injector pump. If you have a good lift pump and there are no vacuum leaks between the tank and the lift pump then it may be down to bleeding the air out of the injector lines first at the pump, and then at the end of the injector lines (be very careful the diesel is at 170 to 175 times atmospheric pressure which is about 2500 pounds per square inch (which can penetrate skin deeply and even bone). Most of the Ford tractors use a rotary injection pump. Having only one cylinder not pressurizing is extremely unusual, try swapping the injectors between cylinders to see if it is a faulty injector, making sure to use new or at least anneal the old copper sealing washers and tension the injectors evenly with a tension wrench to correct torque. If the misfire then follows the injector it means your need the injectors servicing. New needles & nozzles for injectors is a lot cheaper than a new or rebuilt rotary injection pump. Please advise if it’s an inline pump. (which I doubt they were rare because they cost more).

Probly gonna need nu hose. Tu much pressure. Dont try to patch when safety concern. Its monday....

you need 'tractor tire' injector ring seals

I believe that you must increase everything. Is not a good idea adjusting injection pump. Will be a great idea,if you get better best answer from directly from the Manufacturer.
Go and get support from them. Will be more efective.
God bless you

Have someone retime the engine. In a diesel it means to time the injection pump. You may have wear in the timing chain or gears. But the fuel ratio can be made rich or lean by when the fuel hits the cylinder.

Try that first as it is cheaper. You can have worn injectors and adding a cleaner will make the fuel run through faster. Possibly spray a little better, but it will not make the fuel nozzles any tighter.

TPS is bad or inject pump has bad sosenr

It sounds like a problem with your computer or injection system. the computer controls the amount of fuel put in the cylinders when you step on the gas. But it sounds like your truck's computer is having problems controlling this and when you accelerate hard or are towing and step on the gas, the computer just pumps diesel into the cylinders which causes the rough running(i assume misfiring and what not) and the loss of power. But when your not towing or accelerating hard, you are better controlling the amount of fuel going into the cylinders so there arent any problems. Go back to the dealer and tell them there is a problem with the injection system and it adds too much fuel when you try to get a lot of power out of it.

A FRIEND OF MINE HAS A 601 WORKMASTER AND IT IS LEAKING THE TRANSMISSION FLUID INTO THE CLUTCH HOUSING IS THEIR A SEAL OR GASKET TO REPLACE?
