    Could a wiring issue be causing these machine fault codes?

    After shutting off the engine, the green light on the master battery switch stays on and keeps changing brightness. I'm also getting L01 and L04 fault codes. The codes briefly cleared after a manual regen but came back later. Could this be a wiring or electrical issue?

    Why does my Bobcat 763 lose power when I use the hydraulics?

    If your Bobcat 763 idles and drives normally but loses power when you use the hydraulics, check the hydraulic fluid, filter, and hoses first. A strange noise when lowering the bucket may also point to low fluid or a hydraulic pump issue. Regular maintenance can help keep your skid steer running...

    Why is my payloader acting like it's in 2nd gear when set to 1st?

    My payloader has very little pushing power. In 1st gear, it drives like it's in 2nd gear. I did a speed test and confirmed it matches 2nd gear speed. Has anyone had this problem? What was the cause?

    My 2001 Case wheel loader has slow hydraulics. It works better when I rev the engine in neutral, but once the hydraulic oil gets hot, it becomes much slower. What was the cause or fix?

    I'm trying to adjust the throttle cable on my John Deere 550G. I have the TM1404 service manual, but the adjustment procedure points to TM1403, Group 9010-20, which I don't have access to.

    I'm removing the engine from a motor grader and have already removed all the engine mounts. Before pulling the engine, I'm trying to determine if there are hidden bellhousing bolts under the angled top cover of the transmission. Are there bolts inside the top transmission cover that secure the...

    Why won't the left clutch engage properly on my Case 455C dozer?

    I'm having a steering clutch issue on my Case 455C dozer. The left brake applies immediately without the clutch disengaging first, while the right side works normally, with the clutch engaging before the brake. I've already removed and checked the transmission control valve, and the clutch spool...

    What do JD 350G LC codes 2030.09 and 2228.09 mean?

    I'm getting fault codes 2030.09 and 2228.09 on my JD 350G LC. The machine runs fine most of the time, but then an alarm comes on, the engine RPM drops for a few seconds, and everything goes back to normal. Any ideas on what I should check first?

    Case W36 has no neutral position.

    I'm working on a Case W36 wheel loader that seems to have no true neutral. Forward works normally, reverse works normally, but neutral feels like it's partially engaged in reverse, which makes the machine unsafe to operate. I'm planning to do the rear brakes first, but I'm wondering if this...

    How do Deere scraper buckets compare, and what should I look for in a used one?

    I'm considering switching to Deere scraper buckets and would like to hear some real-world feedback. How do they handle polishing work, and what are the common issues to watch for on used machines? Also, are cushion hitches a must when running them behind a 9560R with autoload?

    Link-belt LS 2650 cranks but won't start.

    I'm having a starting issue with my Link-Belt LS 2650. The engine cranks over fine, but won't start on its own. If I give it a tiny shot of ether, it fires right up and runs normally. The problem happens when the engine is cold and sometimes even when it's hot. Fuel pressure seems to be within...

    What's the Best Fix for Persistent Wet Stacking?

    I'm dealing with persistent wet stacking on a Case 207 engine. The head has already been rebuilt, the injectors tested good, and the cylinder liners still look decent. Before I move forward with an in-frame rebuild, I'm wondering what the best fix is.

    I need to remove the heater blower motor. I pulled the seat, but it doesn't look like the blower is accessed from there. Has anyone done this job before? Is there an access panel underneath the cab,

    What could cause a CAT 980B middle brake pedal valve to continuously dump air and stop the machine from building pressure?

    Trying to diagnose a CAT 980B middle brake pedal valve that continuously dumps air and won't let the machine build pressure. The valve was replaced last year and worked fine until now. Could this be a stuck valve, bad internal seal, or contamination in the air brake system? Also wondering if the...

    I'm trying to figure out a transmission issue on my Caterpillar 988A, and I'm honestly stumped at this point. The machine was working perfectly fine.

    I'm trying to figure out a transmission issue on my Caterpillar 988A, and I'm honestly stumped at this point. The machine was working perfectly fine. The operator dumped a bucket, backed up normally, then shifted back into forward, and suddenly nothing happened. Last year, the machine still had...

    Why does the monitor on a Case CX130C randomly shut off, change screens, or switch to Japanese?

    I'm having a strange electrical issue with my Case CX130C and I'm hoping someone here has seen this before. The monitor will randomly shut off while the machine is running. Sometimes it stays completely black, and other times it comes back on after a second but switches to a different screen...
