Also, don't forget to pull the timing pin before reassembly. @Jason1010 I got a copy of the Perkins manual in case you need it.Unless the magic potion frees up the mv(hope so) your destined to pull the pump..
READ THE MANUAL..
THE TIMING IS CRUCIAL ON THAT PUMP AND ENGINE.!!!
If the engine is not set correctly when you pull the pump, you’ll never get it to run right when you put it back on..& u only get 1 shot at it..
Once u break loose the locking bolt for the pump drive shaft.. (timing) and start the engine or crank it.
There’s no putting back the timing from the fuel shop(lock timing)..
If it’s not right, the pump has to go back to the shop and put back on the machine inorder to set the timing again..($$$) it’s not a simple procedure, so u will b charged..
I had a customer once that screwed it up 3x.. and was charged 300.00, 3x..!!!
Fourth sentence he states he tried starting it without doing anything. Then he checked out the fuel supply. Once that was fixed, it started but was going beyond governed RPMs. I thought it was the governor that was stuck, but @thepumpguysc pointed out that it was the metering valve. Learned something new there myself. This is also one of the newer Perkins designs. The magic potion(Stanadyne and ATF) is just something I've used over the years myself to free up stuck injection pumps for further diagnosis. Sometimes it works, sometimes it doesn't.... thinking over the past 16 posts... this is an 18 or 19 year old tractor with less than 300 hrs on it. It was either rebuilt or mothballed for an extended period. Maybe both. I can't see anywhere that the OP tried to start it up and run it a bit before attacking the machine doing 10 or 15 things to it which (while understandable) complicates the evaluation. Almost gotta suspicion that something done during the rehab process was the culprit. Isn't this also among the early years of the 3 cyl Perkins in MF tractors? Surely the pumpguy in Post #16 knows more about this than all the rest of us combined...
