    Default leaking cva fuel pump

    hi, just found this sight, my mf 135 with 152 perkins has a leaking cva fuel pump around the throttle shaft, its a mess & could be leaking a little in other places, I was going to get a repair kit and do it myself, I have rebuilt pumps on 3406 cats before, but just wondering if there are anything major in this pump?

    Not a complicated repair BUT take a good mental note of where spring inside cover is attached and be sure it's attached back in correct position or your engine will not run correctly. Several tractor tech manuals explain the correct procedure.

    Take a look here. It will help alot - http://www.tractorbynet.com/forums/m...ml#post3263129

    As mentioned note the connection points carefully.
    When you lift the cover to unhook the spring there are some small spring loaded parts on the back of the tomb stone that can fly when the spring is un hooked. Keep your finger back there. Good luck.

    I have done this exact repair. As has been said, note which hole the spring is in. Each shaft will require two O rings, some exploded views show only one. This job can be accomplished with the pump still on the tractor. You'll need the governor gasket also.
