Re: Perkins 6.354 fuel pump JCB 814

Okay now I know what we are looking at :thumbup: is it a bad leak or not? Pete I would have thought you would only get this issue fixed by an injection pump specialist?

Re: Perkins 6.354 fuel pump JCB 814

Re: Perkins 4236 engine rebuild rocker shaft

Ian I am trying to picture in my mind where you want to grind this shaft? I would say that you probably could grind it but some pictures of the issue would help. :thumbup:

Re: Thwaites Alldig

Hi Paul and welcome to CMN :wave: I am no hydraulic expert but start with the simple things, is there sufficient hydraulic oil in the machine, is the connection to the operating spool valve okay? Make sure there are no airlocks in the system, does the rest of the machine operate okay? I am sure that...
