Are the diaphragms difficult to install in injector pump.
Are special tools needed?
 

[tiresntracks]

Its not too hard. Remove the vacuum line from the gov. housing to the manifold. Take the 4 bolts out of the housing. The spring will try to push the housing off, so be ready for it. Pull the diaphragm out and remove the washer and cottar pin that hold it on the fuel control rod. Install the new one exactly the same way that the old one came out.

Do i have to remove the iinjector pump from the tractor or can i replace the diaphragm while the injector is still attached to the tractor???

You're welcome!

You can change the diaphragm while the injector pump is still on the tractor.

Thank Again!!!!!!

my tractor runs great!!!
Thanks TIRESNTRACKS !!!!
can this tractor burn biodiesel?
 

[tiresntracks]

I'm glad that you fixed the problem.
I don't see what it would hurt to burn biodiesel. The fuel system is pretty basic. I've never used biodiesel myself, but I've been told that you will need a few extra fuel filters when you first start using it and it gels at a lot higher temp. than diesel.
 

[gregory scott]

when you say it gels at much higher temp than fosel fuels are you saying that it cant handle lower temp?
 

[tiresntracks]

Yes. That's what I meant. I don't know the exact temps, but I know it doesn't work well in cold weather, unless you mix it with something else, or use a tank heater. It also varies, depending on what type of oil it was made from.

Thank you sir.
