I have a 317 skid steer and it was not starting. I was getting diesel in the engine oil. Changed the fuel transfer pump. Thought it was leaking. Not the prob. When I manually pump the pump I still get diesel in the oil. Later taking the valve cover of found a broken fuel injection pump. What would cause this??? What more should I be concerned about???

yes each injector has its pump. The skid would loose power and not die then clear itself and run for hours and then act up again. However the last time the little shaft between the springs on the pump broke. Only 1300 hrs
looking down wear the pump goes you can see the cam and there is a small nick there. How bad will it affect the new roller that rides on there and drives the pump?
Is it just a small nick or a big gouge? You really want the roller to run over the cam smoothly and not damage the new pump.... If it is small and the roller will still run over it smoothly, i wouldn't be worried.
Pumps locking up was common. They seize and when the cam lobe comes around, it breaks the clamp. I don't think a knick in the roller is a big deal, but look closely at the sealing area for damage, that is the block itself. Unless Deere has come up with a fix since I left, if that is banged up at all, the pump will not seal. The engine block is junk. I replace many pumps and a few engines. I would recommand you call a dealer, the pumps need to be timed with in thousands of easch other or the thing will fall on its face.
The clamp that hold down the pump broke. The small nick is on the cam lobe. The roller broke off also and fell down to bottom of the oil pan when I was pulling the pump out I think. I heard something tink as I pulled it out and there was no roller just that sleeve. Also when the machine ran rough & lack of power then clears itself was that the sign the pump was going?
The clamp broke because the the pump is locked up. This was a BIG problem on these. The cam follower is seprate piece from the pump, it just rides against the bottom of the pump. I don't thing the actual roller could fall threw, but if the plunger on the bottom of the pump fell off, I guess that could make it down there. When those pumps go, a lot of time they will run already without a real noticble miss. They will lack power when pushed, but most guys notice the oil level is going up and didn't complain of power.
The thing just keep getting worse The bottom of the cam foller and roller broke into pieces. We were able to get all the pieces out of the oil pan. Now they found out was when the tried to turn the crank shaft the cam shaft does not turn. Now what is wrong? How much more can go wrong? Everyday things keep going down hill.
The cam is gear driven off the crank so I have no idea, have to rip in to it.
well the shop I have it at recomends I just start looking for a new engine. A few of the push rods are bent also. They say by the time I start replacing parts I am better off finding a new engine.. This is a bad day. Now I must find one somewhere in Sask. Canada The price just keeps going up. Not fun with only 1300hrs

Is it that bad? Do you have the head off yet to check for bent valves? You should be able to repair it for less than the cost of a good used engine. Besides, a used engine is a crap shoot. You may be right back to the same place before you know it. But if you do decide to go that route, I am in Ontario, and there is a large tractor wrecker about 10 km from my place called Fawcett's. They ship all over Canada. If anybody is going to be able to help, it will be them, whether it is a new engine or reasonably priced parts to fix what you have. Their number is (519)284-2379. HTH.
Sounds like you may need to pull the engine down to assess the damage.
If the injector cam isn't moving, it's possible the timing gears or chain that drives it and the cam shaft has broken. You may be lucky for the push rods to be the weak point to save the valves. Deutz made their oil cooled engines like this to save major damage if the timing belt was to let go.
There has to be problem with the timing gears or the cam snapped, that is the only way the cam would stop turning which would explain the bent pushrods. In 2005, those engines where just over $8,000.
WOW $8000 I need to find some options The shop already has three days labour into it. I need to find a complete reman engine and stop the bleeding.
The Fawcett tractor salvage has a decent web site also, St.Marys is right by the Soo locks isnt it SkidRoe?

St. Mary's is about 30kms northeast of London in Southwestern Ontario, about an hour and a half west of Toronto. Fawcett's is a bit of an unknown gem, a lot of us who live here take it for granted.
Well its still confusing what caused what. As they were swapping parts over to the reman they found the gear that turns the cam was loose. The bolt had backed off and seeing how the gear is only a friction fit on the shaft all the timing went out. The bolt threads were not stretched. I thought maybe when the pump seized the cam spun inside the gear. But why was the bolt backed off that holds the gear. Confusing?

Sounds like a torquing issue to me. It is not uncommon to have friction fits on cam drives (VW has done this for years on their diesels), but they have to be tight. Where did you end up getting the reman engine from?
