    New Holland B75D Backhoe

    Across from work is an equipment dealer and a shiny new backhoe showed up. I had to inquire. It was a JBC backhoe for about $128,000. I started looking online and the rest of the big-name brands are at a similar price and much more depending on the options. Then I came across an ad for a 2022...

    580C donor carcass

    I found a good deal on a partial 580C. It was mostly stripped of the major parts. I ended up with the front axle which is mostly garbage. The yoke is egged out from lack of maintenance. Other parts are the steering valve, shuttle shift with torque converter, transaxle, front console/electronics...

    John Deere backhoe- What am I?

    My friend bought some property and this backhoe may be left behind since it is not running. I've never seen a John Deere 310 backhoe that slides on a rail and I can't find one like it with an internet search. How does it move back and forth horizontally? I did not find a rack and pinion system...

    John Deere 200LC general maintenance & operation questions

    Hello, I'm helping a friend get a John Deere 200LC up and running. It appears to be in great condition with only 5,600 hours. It has been parked outside for most of its life and has seen little use with the prior owner. It has not been used in several years. It was part of a land purchase that...

    580C stabilizer rebuild

    Has anyone rebuilt the welded-in swivel bushing #7(part #D60803) on the frame where the stabilizer arm attaches? Are the welded on side plates machined with a partial sphere? I can't tell by the parts manual or with a flashlight looking at the worn-out mess. This was a monster to get apart. I...

    CAT 304E2 overheating

    Hi, I'm renting a CAT 304E2. I ran it about 2 hours digging and pushing a little dirt. It's a 92 degree day. I had the AC on, but it's not very cold. Ran the engine one notch down from full power. The alarm went off and I got this screen message: "E361[3] high engine coolant temperature...

    580C brake rebuild questions

    I've spent a few hours reading on HEF and other online forums about rebuilding the brakes on a 580C. It looks like I need to tear into this from one end to the other. I looked in the manual and couldn't find any specifications on the linings for both the links and the discs. What is the...

    580C Transaxle- whats on my gears?

    My 580C has sat for about a year. I do start it, but have not been driving it. I started working on the brakes today and the cross shaft was stuck. So I took the lid off the transaxle so I could press the shaft out. I was shocked to find what I would call small steel filings mostly on the...

    Ziploc bag trick for tiny o-rings

    Not sure if the following is an original idea or not. I have snapped three tiny o-rings(.101 ID X .07 thick) trying to install them on the guide that is inside the secondary relief valve to the loader control valve on my 580C. I put the guide and the o-ring in hot oil on the kitchen stove. By...

    Creating a Topo map without a total station

    Is there a practical way to create a topo map with say 2-foot contours using a regular laser level or optical transit? My designer would like it around 20 feet outside of the building footprint(50'X50'). Hiring a surveyor is out of my budget. I know how to plot a level line, but capturing all...

    Air dryer filter corrosion

    I bought a used 50CFM refrigerated air dryer from a machine shop. It's about 8 years old. It was installed indoors and the air compressor was outside in a shelter. The air compressor was a big Quincy brand piston type. I took off the side panels to clean the coils. The outside of the copper is...

    580C Loader Control Valve repair

    I'm rebuilding the loader control valve on my 1980 580C. I don't think the insides have seen daylight in 40 years. The spool seals were leaking and most of my power beyond o-ring was gone. I've read the service manual and searched online for any information on what is acceptable wear on the main...

    3D printed tool

    I'm rebuilding the leaky loader control valve on my 580C. I got stuck removing the plastic gland nut and didn't want to butcher it up using the wrong hand tools(It's the machinist in me). So I was going to CNC mill a custom castle nut tool then decided that would take too long. I decided to see...

    1996 JLG 45HA repair questions

    Hello, I just bought a 1996 JLG 45HA 4X4 articulated boom lift. It has the Ford gas/propane engine. Serial #024262 0300022807. Overall it's in OK shape for its age, but needs some things repaired. I find the JLG engine and hydraulic oil charts difficult to interpret. I live in the Willamette...

    Cylinder piston/rod bolt torque values

    Greetings, I was helping a friend rebuild a boom cylinder on a 580D. The bolt is a 1 inch grade 8 fine thread. The service manual says on page 4090-3 to torque the piston bolt to 475-525 foot pounds. But the general torque values on page 1051-2 says the grade 8 bolt should be torqued from...

    580D backhoe attachment compatible with 580C?

    Hi, I'm looking at a used 580D backhoe attachment for my 580C. Will it bolt right on my 580C without any modifications? This one is in good shape and mine needs a lot of repairs. Also it has hand controls, and due to a leg injury I'm struggling with the foot swing. So this would be a nice...
