My CAV injection pump was starting to leak so I replaced a few orings and a gasket and the leaks are fixed. For full CAV teardown check out Bundy Bears Shed • CAV Injection pump ful...
You, my friend, are a life saver! I have a yellow Massey 20C. It has the exact same Perkins engine as the 35 and I have the exact same fuel leak problem. Thanks for your detailed video!
Thank you for the video. In the kit there are also two little rubber washers to seal under the holding nuts. I find it easier to remove the nut from the throttle shaft and push this down through the cover while taken it apart, that way you don't have to remove the spring. The position of the governor spring is stamped on the blue sign on the pump.
Well at least one thing it was easy to get to. Can’t believe there ain’t a drain plug in it. Like a drain plug in a carburetor bowl. Thanks for sharing. Take care
There quite possibly could be a drain plug I did not see one. I would think had I disconnected a fuel line I could have drained it out that way. Thanks for watching.
I would check for fuel flow from the tank. Pull the fuel supply line off the injector pump and make sure fuel is flowing freely to ensure petcock, filters, and fuel lines are not obstructed.
@@thedelcodave i did that, its coming fuel everywhere except in the 3 injector pipes took them off and cleaned them nothing wrong there. It looks likte the pump wont pump any fuel. Opened that that, did look good. I might have to deliver it to a tractor company for proper inspection :)
How do we prime it after filter changes? I've got the air out of the filters and the bleeder screws on the injector but I don't have making it to the injector fittings?
If you have it bled up until the injection pump. Break each injector line loose at the injector and crank it will take some time for the fuel to get up to the injectors. Crank for 30-60 seconds them let your starter cool off for a couple minutes. Also set your throttle to 3/4 full.
@thedelcodave I have fuel coming out at the injector fittings now, but still won't start. I wonder if bad fuel pump will cause problem. Im only cranking 10 seconds. How much fuel should it pump out, I think I have less than your vid. It starts with ether.
It will shoot little squirts of fuel out each line. If it ran before you changed the filters then it most likely still has air in the system. Tighten 2 of the 3 fuel lines on the injectors and leave the 3rd one cracked loose. If you can get it running on 2 cylinders then tighten the last line when all the air is out. These tractors have the lift pump but the tank is higher then the injection pump so they gravity feed pretty good.
@thedelcodave we got it to run using ether. Maybe new fuel pump will help prime it better. The manual lift pump on mine didn't do a lot. This Is the perkins 4.236 on the backhoe, I put a vid on my channel
