The older hoes had the Hyd valves on either side of operater, the later hoes had the valve bank under the operater. Not sure if that was when the change to 3141 series started.
3514 was built from 1969 thru 1972 Serial # started at 501 Thru 3769. If that # you found is right it is one of the oldest. Serial plate was like all IH Approx 2X3 fastened to the clutch housing
The plate i took the picture of was on the frame itself. If you look at the first picture I posted, you cannot see it but i found it right behind the lift cylinder for the front loader. I hope that is a correct number. If so I can pretty much determine that it is a 1969. It runs smooth. I have no complaints with the motor or trans but some of the pins are a little sloppy in the backhoe and i have an issue to address with the pivot shaft. The seal that is under the splined mounting bracket on the pivot shaft is junk and leaks pretty good. Im gonna drop the backhoe off of the tractor and go over all the mechanics and hydraulics. Quick question..... Do you happen to know if the hydro line that comes from the top of the splined shaft is a return line or a pressure line? Just seems to me that its there to return fluid leaked into the rack housing. And the valve bodies are underneath me when I'm sitting up there. The last picture shows the entire setup there. No covers though. Must have been a casualty of war for a hard worked machine. I will fabricate them once I iron out all of the issues. Again, thanks for the info. It really helps me to better understand what I'm getting myself into.

Today's Featured Article - The Great Escape - by Dave Hollrah. It all began Monday with a little baling of second crop on the lake shore field, and as I drove out past my sister and her hubby's place, this small calling sound could be heard from the general direction of their manure pile. Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
