Ford 5000

[Bennelli]

My wife thought it would make a good tractor to ride in tractor drives so when she got it home I tried to start it but it started hard and every time it was a chore to start . So I decided to check into it and I tore it down replaced cam as it was chipping away took and had the block bored and sleeved the crank turned put new bearings in and bushings put it all back together and had the injection pump done 3 times the head checked and redone 2 times , put it all back together then put new rocker assembly in it then started and it still does not have good throttle response and when you go full throttle it pops so checked the timing again and it is right on for the pump and the engine anybody have any ideas I’ve rebuilt many engines before but this one has me stumped?

Why so many times.

What are you setting the timing at and which year model do you have
Why have the injection pump done 3 times and the head twice, also what do you mean by having them done

 

[Dieseltech]

WHICH injection pump does it have? Early used the Simms P4666, later used the P4862. The LATEST 5000 uses the CAV DPA rotary pump. Did the head get ALL NEW seats installed like most older heads need? OR were the valves and seats just re ground and used as is? THAT will LOWER all valves TOO MUCH below the deck surface causing HARD STARTING when cold. Has a COMPRESSION check been done?

 

[Bennelli]

It is a 1967 British tractor , had the pump done 3 times because after I had it done the first time it had a leak and it started surging then I got a different pump because they couldn’t rebuild it by the time I needed it then it still wasn’t firing on 1&2 so I took it to a different place and they rebuilt it with oem parts not the aftermarket parts. It is Simms injection pump . They rebuilt the head and put new seat in . The compression is 380-400 across all cylinders. The reason I keep checking the timing is because when it is running it sounds like it is out of time.

Hello Bennelli, welcome to YT! You had the head worked on once and put it on and something was wrong so you took it off and had it redone a second time?
Ford guys, could a gas camshaft be put in a diesel? Or does the British build origination put that possibility out of play?

Same camshaft gas or diesel on the 5000 no matter where it was built

No just checked over because it lost compression on number one cylinder after that I had the block bored and sleeved

A couple very basic things to check, Do you have good fuel flow to, and from your low pressure fuel supply pump. Remove the oil bath air cleaner base, and check the filter media. I have seen the mesh so plugged with dirt and chaff, that the engine would barely start and run. Also have seen them so full of water, that they couldn't breathe.

 

[Bennelli]

Good fuel flow and and it is a new breather and new oil in the breather

You may have a Fordson Super Major 5000 which is totally different from a Ford 5000 built in Highland Park MI.

The FORDSON Super Major 5000, was a wet sleeve. The FORD Super Major 5000 wasn't. He said he had it bored.

That was one of my first thoughts as well when the OP mentioned it sounding out of time and misfiring, even after all the engine/pump work. It wouldn't be the first time someone's had a similar issues with the Super Major 5000's connecting the injector lines wrong, forgetting the firing order on them was 1-2-4-3 on those Majors. But the OP mentions it's a 1967 model. I'm pretty sure the Majors that were re-badged as 5000's ended in '64 or '65.

While it's not really proper nor correct to judge from a distance, it sounds like there may have been some questionable work done by some shops. Aftermarket or OEM parts shouldn't really matter for the pump. At least, not once it's assembled and been given the 'all-clear' from the pump shop, because any shop worth their salt would have bench tested it upon assembly. I've had had a few Simms/Minimec pumps worked on (5000 & 6600). Never worried/considered if the shop used OEM or aftermarket pumps, but I've never had a problem. And certainly never had to take one back. Someone would sure be getting an earful if I did. Also very curious why the head had to go back a second time? Should be pretty standard practice for any engine shop worth their salt to put new seats in properly and grind/replace the valves to get the correct seal & protrusion.

The fact that it 'lost compression' after a head & bore/sleeve job also sounds very dubious. If a block was bored/sleeved and the head rebuilt, something had to be either installed very incorrectly/wackily (head gasket? fire rings? cam?) or one of the shops must have done something horribly wrong if it caused compression to drop out. Given that the 5000 had a sleeveless block from the factory, it would be good to know what sleeve kit/size (and head gasket) was put in.

In my opinion he needs to give more of the story and how he progressed through the multiple steps of the same repair, he did give some information about the injection pump repair. On the head did he assembled it and then it ran with the problem he stated and pulled it apart again and it now is doing the same thing again after the second assembly.
Might end up sending his pump to Dieseltech to make sure it is right.

Pop/ slow throttle response could be a broken or disconnected rocker arm.
