Why does my 1979 JCB backhoe not start?
The 1979 JCB Backhoe would not start after sitting idle for 4 weeks. I suspect I lost prime and air entered the system. When I spray starting fluid it starts for a instant. Please note I observed alittle diesel which had leaked from the top of the fuel injection pump where the throttle attaches.
How do you blead a JCB backhoe?
I blead the system through the bleed screw on the fuel injector pump and then blead the fuel lines where they enter the fuel injectors on the bottom. I was able to get a small amount of fuel pulsating through the injectors.
How do you Prime a JCB 214 backhoe?
You have to prime from the bottom up. Loosen the bleed screw on top of the fuel filter and pump the primer till all air is expelled from the filters. Move up to the injection pump and find the bleed screw on it and pump again till all air is expelled. Loosen the injection lines at the injectors and crank engine till you see all air expelled.
What should I do if my backhoe won’t start?
I would loosen the injector lines and if you have a primer pump pump that while turning the engine over. Some injection pumps will have a small bleeder screw near the middle of the pump and that may need to be opened first to get fuel into the pump. Once fuel is pulsing out the lines the install and it should fire up.

Where is the fuel line on a JCB backhoe?
One line from the fuel filter cap to the fuel injector pump. One return line from the fuel injector pump to the fuel filter cap. And one line to what appears to be a switch which is not hooked up electrically. Also a fifth line (rubber hose) comes into the center of the fuel filter cap from the top of the injectors.

How can I Fix my JCB 3CX movement problem?
I had to replace the forward microswitch; that fixed my problem. You may be able to verify if the problem is electrical by verifying that the reverse solenoid is energized by touching it with a screwdriver blade – the blade should be attracted to the body of the solenoid.
