Combines saurer hydro

Several years ago had one rebuilt by Hydro Service in Roland,Ia,dropped it off at 7:30 and picked it up at 1:00 the same day.

Silver Dollar Saloon, Who is the supplier for AGCO in IowaIJ I have all of my hydros rebuilt at Hydro Service Inc. in Roland,IA..Just like Big Orange said,make an appointment for it and it will be ready the same day.These guys are excellent troubleshooters for all colors.They also rebuild hyd. pumps,hyd. motors, skidloader hydros,and tractor hydros.

We have very little trouble with that hydro but when we do and combine needs to keep running we switch with a core we keep on hand. We keep the core on hand with short shaft so it can be used on many years and models of combines with the right pulley. We will then rebuild ourselves as time permits and Hydro services in Tulsa OK do the machineing. We then switch hydro back so they keep there original rebuilt. Not to hard to find Dynapower and Denison hydros for the machines built in '80s and prior in salvage if you need a quick fix. As long as failure didn't put a ton of metal into system its easy to switch out hydro. If there was ground up metal type failure you will be in for a bunch of flushing. Be sure to change hydro filter as suggested for I find that the major reason these hydros get weak is junk going around plugged filter. Good luck getting her going

I would like to know where you get your Denison hydros repaired. We had one go out on a 85 l3 and we had a hard time trying to get someone to rebuild it. We took it to a shop near Oklahoma City and it lasted two seasons before a bearing went out. We then found one in a salvage yard near Colfax, Iowa. That was in 1999 and hydro is still going. At the time a rebuilt hydro through AGCO was over $7,000. Everyone said these were good hydros but we have not been as fortunate.

We do our own Denison however rare it be. They are a little more complicated than they need to be. They are a fantastic hydros but parts are crazy and I believe that is common with any OEM German parts. There are few outfits that will monkey with the Denison as I have found that out also. I get the parts from Gleaner and machine work goes to Hydro services. If a guy had enough trouble with a Denison you could switch it up to Sundstrand without to much trouble. Sorry to hear of bearing that went after only a couple year on rebuild but these things happen. Was it such a bearing that required a replacementIJ Most of the time it isn't so serious.

It was the outside bearing that went out. It was right smack in the middle of bean harvest that year and we needed to get back into the field quickly. We bought a replacement out of a salvaged M3 and it has worked smoothly. We still have our old hydro sitting in the shop. That has been the only major problem we have had with the l3. Correct me if I'm wrong but didn't they use the Denison in the R5, R6, and R7 alsoIJ

The first factory N7 used the Denison. N6s followed suit in '82 I believe. Then Gleaner used that brand into the R60 and 70s. I'm a little unsure but I think only a year if that in the R60 and 70s. They've been using Sundstrand ever since. Take care
