    Why won't my Lull 944E-42 start after replacing the fuel filter?

    My Lull 944E-42 with a Cummins diesel engine started sputtering and stalling before it stopped starting altogether. I cleaned the fuel system and replaced the fuel filter, but it still won't start unless using ether. What could be causing the problem?

    How can I add a third hydraulic function to a Volvo L70C wheel loader?

    I recently bought a Volvo L70C wheel loader with only two hydraulic functions, but I need a third. Since the original valve kit is no longer available, are there any aftermarket options that work with load-sensing hydraulics?

    How do I bleed a hydraulic quick hitch cylinder on a Case mini excavator?

    I had the hydraulic quick hitch cylinder on my Case mini excavator repaired and need to reinstall it. Should I bleed the cylinder manually, or will operating the attachment remove the air? Also, what is the correct boom and bucket position for checking the hydraulic oil level?

    Why won't the left stick move on my JCB 180?

    My JCB 180 Robot skid steer has normal boom and curl functions, but the left stick won't move forward or backward. It worked briefly before failing completely. Could this be an electrical problem?

    Why is my Cat 615C losing power?

    My Cat 615C loses power when loaded, and the torque converter sometimes slips. Both issues started recently. Any ideas?

    Why won't the tracks unlock on my Bobcat T180?

    My Bobcat T180 runs great, but sometimes after I lift and lower the seat bar, the tracks won't unlock. The warning lights come on, and the lift and tilt functions still work, but the tracks stay locked. The only fix is to shut the machine off and restart it. Has anyone had this issue? What was...

    Can I replace my CAT bucket teeth with wider grading teeth?

    I have a CAT bucket with 7 digging teeth and would like to replace them with wide grading teeth (around 200 mm / 8 inches) for grading and ditching instead of buying a new bucket. Is this possible? If you've done it before, where did you buy the teeth, and did they fit without any modifications?

    Why is my John Deere 690 ELC getting air in the fuel system?

    I'm having a fuel system issue with my John Deere 690 ELC. I've already replaced the water separator, lift pump, fuel line, and glass fuel filter. The excavator runs well for about 20 minutes, then loses power, stalls, and won't restart until I reprime the fuel system. I also noticed air bubbles...

    Anyone here bought a used CAT 320 excavator from IronPlanet before?

    I've noticed the same thing. IronPlanet's inspection reports and videos can give you a much better idea of a machine's condition before bidding. Of course, you still need to do your homework, but I've seen some really clean machines show up there over the years.

    Why won't my machine stay in 3rd or 4th gear?

    My machine won't shift into 3rd or 4th gear. Sometimes I can get it into 3rd by shifting through neutral, but it only stays there for a few seconds before downshifting. The brake pressure switch also started blinking today. I just bought the machine & it has 5,051 hours on it. I've already...

    What’s the best equipment listing you’ve seen on Boom & Bucket lately?

    In my experience, the best listings aren't always the newest or biggest machines-they're the ones where the seller provides enough detail to build confidenc

    Can anyone help identify the correct wires and connector type for a Hitachi sensor test harness (ST1729)?

    I'm trying to troubleshoot a sensor on my Hitachi and could use some help with the ST1729 test harness. The service manual shows wires 21, 34, and 35, but the diagram is pretty hard to read. It also labels the connector pins as 1, 2, and 3 from left to right, and I'm not sure which wire I should...

    How to clear common codes on the GR-500XL?

    That's solid advice. A lot of AML-C codes end up being setup or sensor-related rather than major failures. We've had cases where cleaning a dirty limit switch or reseating a pin cleared the issue immediately. Definitely worth checking the simple stuff first before calling service.

    Does the gearbox on a 1996 JD 7775 use separate oil, or is it lubricated by the chaincase oil?

    I recently bought a 1996 John Deere 7775, and I'm getting ready to change the chaincase oil, but I'm finding mixed information online about the gearbox lubrication setup. Some people say the gearbox has separate oil, while others say it's lubricated by the chaincase. Under the seat, I found...
