I'm working on a Cat 140H grader and need some clarification. Can anyone explain the difference between the movement solenoids and the injector solenoids? Also, is the engine shutoff solenoid the same as one of the movement solenoids, or is it a completely separate component? Any help would be...

I'd start with the basics-change the transmission filters and check oil condition and pressures. The blinking brake pressure light could be putting the transmission into a protective mode and preventing 3rd and 4th gear engagement. Also inspect the brake pressure switch and wiring before...

My machine has completely lost steering in both directions. Hydraulic pump pressure is good, and the steering valve, solenoids, and cylinders have all been checked or rebuilt. Oddly, if I disconnect the steering manifold return line and let the oil spray out, the steering works fine. I also have...

Hey, fuel costs can have a huge impact on the profitability of any earthmoving project, especially when running articulated trucks every day. What operating habits, maintenance practices, or jobsite strategies have helped you improve fuel efficiency without sacrificing productivity? I'd love to...

One tip that's helped us is making sure the software integrates with telematics data, not just schedules. Knowing where machines actually are and how much they're being used can uncover a lot of hidden idle time and make equipment allocation decisions much easier.

Compact track loaders seem to be showing up on more jobsites every year. What do you think is driving their growing popularity? Is it better versatility, lower ground pressure, improved attachments, or simply the ability to handle a wider range of tasks than ever before?

I agree with the spotter advice, having a second set of eyes can prevent a lot of close calls. In tight spaces, I always remind myself that taking an extra minute to reposition is a lot cheaper than repairing a lift or a building.

My 2006 Volvo L110E won't go into forward or reverse. A Volvo tech checked it and thinks the problem is inside the transmission. Has anyone had this happen before, and what was the fix?

I'm looking for rear-end parts for a 1989 L140 loader, or possibly a complete rear end. Does anyone know where I can find parts or have one for sale?

CAT, Komatsu, John Deere, and Volvo all seem to offer strong telematics and machine monitoring tools

I'm troubleshooting a Cat 520E backhoe where the backhoe functions and outriggers are not working. I found a blown fuse and am wondering if a faulty lockout solenoid, damaged wiring, or another electrical issue could be causing the problem.

Sounds like one of those days where the telehandler earned its keep! It's always impressive how much work those machines can get done even when site conditions are far from ideal.

I don't have a service manual yet, so I'm looking for advice from anyone who has dealt with a similar issue.

Lots of good points here. One thing I don't see discussed as often is resale value and parts availability. Have any of you found that certain brands hold their value significantly better or are easier to keep running after 8–10 years of heavy jobsite use?

One thing that always stands out on IronPlanet is how clean and well-kept some auction machines are.

I'm chasing some intermittent power issues that keep blowing fuses F8 and F18 and could really use the wiring diagram. Thanks in advance.
