10006 Deutz

A question for the pump experts. Is the input shaft on the Bosch rotary pump tapered where it fits in the drive gear? I have everything loose but can't pull the pump from the engine.

Yes, it's the 17 MM taper with a key for timing alignment. Some early Bosch a size inline pumps had the same size, but most have 20 MM taper.

How much pressure can I put on the pump without damaging something? I will try putting the nut on again & trying to hit it but it is at a poor angle to get a direct hit. No room for a puller.

I was wondering if you had to remove the gear to get the injection pump off.

I put new hydraulic pumps on our 13006 this spring and faced the similar issue removing the old ones. It has tapered shaft also in which the gear has to be removed to get the pump off the engine. I had trouble just getting the nut off! I cannot explain it, but the engine would keep on turning even though transmission was in gear and tractor was not moving. Eventually, cause it is a tandem pump,I separated the two pumps and then was able to put a vice grip or crescent wrench on the pump shaft coming out the back of the first pump.

After getting the nut off, I know I did have trouble getting the gear off but cannot remember what I did to finally get it to come off. I remember pounding on the shaft from the front of the engine and I know a crowbar was involved, but I cannot remember exactly what finally got it to budge.

I had the advantage of being able to destroy the old hydraulic pumps. Obviously you are trying to preserve your fuel injection pump.

There has to be a better method than we both know of. Removing the hydraulic pumps and injection pumps is a pretty common thing.

Good Luck! Sorry I could offer any help.

The gear is steady & not being held by the pump. There is another disk with 3 tapped holes that bolts up to the gear. Gear is slotted so timing can be adjusted This disk is what drives the pump & the pump shaft is stuck in it. I will be getting a brass rod to try & smack it on the end to free it. I took the lock washer off & put the nut back on. I don't want to risk a fire by heating it as I am alone in a wheel chair. I will take my time as the engine is stuck. I am soaking the pistons with ATF.
