    I'm feeling lucking! 1987 NH Ford 3910 with no hydraulic pressure for loader/backhoe.

    I have had this tractor for 30 years. I added a Koyker front end loader 25 years ago and added a Case 125 backhoe to it 15 years ago. This is an open center system. I turned this farm tractor into a backhoe is what I did. All has worked well until this week. While using the front end loader to...

    Clogged transmission screen with bore scope pictures. How to clean???

    Just to follow up on this. I got the tractor put back together and everything works as it should. Previous fluid aeration problem is gone and MFWD/2WD switch is now working properly. Nice healthy system pressure too at 250 psi.

    Clogged transmission screen with bore scope pictures. How to clean???

    That syphon spray gun might work. There is one 90 bend in the pipe and its a pretty good diameter like 3/4" ID. I thought about running diesel fuel through a pressure washer :) straight into the hole. The large lower left hole is the one I have to go after.

    JD 310E backhoe transmission system pressure study?

    I connected a 300 psi gauge to the System Pressure port today and I have 230 psi at this port after I crank the tractor. This seems to be normal. Releasing parking brake momentarily drops this pressure to 150 for a second, but then its right back up to 230. Then after 10 minutes or so of...

    JD 310E backhoe battery light on and tach has quit?

    I have a new to me JD 310E. Today while operating the backhoe, the battery light came on and I noticed that the hour meter has also stopped running. I pulled the panel face where these reside and didn't see anything obvious. Any tips, wiring diagrams or links to such things greatly appreciated!

    Can you haul a full size Trans mule in a 8" bed pickup?

    I'm headed to see a Trans Mule and just wondered if I can squeeze it in the back of a 3/4 ton Chevy Pickup w/ 8" fleetside bed. The mule is listed at 57.5" wide while the truck bed measures 59". Has anyone done it??? Also, this is a one time deal.

    Over running clutch, do I need one?

    When I push in the clutch on my Yanmar 2310D, my PTO stops turning until I let the clutch back out. This makes me wonder if I even need a over running clutch?

    YM2310D clutch inspection?

    When I engage the clutch I can hear a slight noise from the throwout bearing. I would like to put a little oil on it. I've notice a rubber plug in the side of the bell housing and wonder if it might be possible for me to use a seeSnake type borescope with small oil tube attached and oil the...

    mud on cylinder rod= impending doom!

    As some of you know I bought a 10+yr old backhoe a few months ago. After a couple of days use the dipper cylinder started mudding the rod. I had noticed the wiper was all cracked up and didn't think too much about it. Apparently dirt gets in next to the packing and just kinda sits there until...

    Crimp specs. whats the tolerance?

    I cannot find it now but I thought I read here in the Hyd. forum that the crimp spec. for hydraulic hose is +-10thou. I just crimped my first one: Used a Weatherhead T450-1 crimper, 3/8 collet, homemade "black" press spacer 3/8 100R2AT hose (ref. Weatherhead 425). It crimped at .802" with my...

    Hydraulic hose crimper, which one?

    Ive built a log splitter, rehosed a backhoe, FEL is next. Maybe I should invest in a crimper. A little mobile one would do it. All kinds of different makers of fittings on Ebay which brings up the question. What goes with what? Can a cheap older crimper do the job with new crimps from...

    Oh man, I've got a tough one, piston bolt.

    Blew a dipper cylinder seal last night while digging up a stump. Pulled the glad with cylinder still on tractor no problem. Its a 3" bore 1.5" rod cylinder, small Case backhoe. The piston bolt is giving me trouble though. I have used a good IR 3/4" impact on it to no avail. I then heated the nut...

    Backhoe  Ford 3910 married to a Case D125 backhoe?

    Thats what Im trying to do. Im guessing a subframe is the way to go, but how? Backhoe is 1600lbs and base tractor is 4500lbs + FEL. I've included some photo attachments. Im looking for ideas. The tractors FEL presently provides a subframe, so tempted to try a 3pt setup first, but I know its not...
