| Our 7010s injector pump managed to come apart (literally). We have another running engine out of a combine however the injector pump is an inline not the circular rosa master. It has Minimec pump (that what the pump says anyway. My question is will this injector pump replace our existing 7010 rosa master pump if we can change the pump what needs to be done or should we replace the entire engine with the combine engine? |

| I don't know what has failed in your injection pump, but I would never advise swapping a (good?) running engine for some 10 year older and unknown condition combine engine. Fix your pump or buy a used pump from a salvage yard and have it freshened up. A pump from a 7000-7010-7020 or M2/M3 combine will fit. |

| From a labor standpoint, an injection pump swap is a couple of hours and takes minimal tools. An engine swap from a combine ?? waaaay more labor than you can imagine by comparison. |

I cannot imagine how bad a Roosa DM could fail to make swapping the entire fuel system or even engine over to get it going. Sometimes you just have to bite the bullet and call in a professional lmao!

I'm no expert, but will chime in. Mostly curious as to what could have possibly happened to your roosa pump to make it unrepairable? I do know for certain that getting a roosa back on there, whether it's having yours repaired by a good pump shop, or finding a different one like it, will definitely be best route to go, like Dr and Ed said.

| Seems like I remember this tractor having hard starting issues some time back and pump timing was in question. I thought the pump had been just gone thru at that time ?? Maybe not. |

“Managed to come apart (literally)”. Sounds like something that should be explained. Preferably with pictures. |

| Yes DR it is the same tractor - we had the pump rebuilt by ST Joe diesel in St Joe MO. The warranty was only a year so we got a used pump and that one is the one that flew a part. |

well, I got the St Jo pump in and apart, sadly the head is seized. The leaf spring screws had backed out quite a ways(had to be really low on hp) to the point one of them began hitting the lobes of the cam ring. So with any internal unhappiness, they end up seizing up. It looks like the cam ring had been replaced as well as the head and rotor being a rebuilt one by the looks of things. The DM pumps use shoes that are .005" difference in sizes, and a lo hp app like a 7010 would use -020 shoes, that keeps the leaf spring screws in most of the way letting their nylok patch hold them in place. Well, this one has new looking -015 shoes so in order to close down the roller setting the leaf spring screws would be out further, therefore allowing them to simply back out. I texted Gary some pics, so hopefully he can post them up, I am not smart enough lmao! Sad to see the poor work coming out of the big shops, and they won't back it. This had to be making horrendous racket while the screw was hitting the cam lobes, could have saved the head if it would have been parked and pulled off before catastrophic failure. Looked closer and it has -010 shoes which is even worse. Almost like they only want to stock the one size. The leaf spring screws are loose, the one that hit the lobes turns with my fingers. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

Ed, I just want to say thank you for posting up what happened. I have been misled by so many injection pump shops in my life. I really appreciate that you are honest on here and give proper advice. I sure wish you lived close enough to me I could drive up to your door with my pumps and injectors. Its hard to have faith in shops when you post that they used the wrong parts and that they assembled it so the screws could come loose. Almost makes a guy wonder if it was the first one they ever worked on and they never read the spec sheet how to assemble

Thanks Gary for getting the pics up. Hopefully your other pump that flew apart will have a good head & rotor in it. I have a new h&r in stock and warehouse has several too, but the $1600 price tag stings! There's lots of these DM pumps around to steal parts out of yet.
You can see the screw is worn down on top, and the notch in the center of the cam lobe is from it wearing on it. Any side load on the rotor will cause it to seize. This could possibly have been saved if it was noticed to be making more noise than normal. I'd never seen this before, so I would not have guessed this was happening. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".
