I'm getting a 989L00 error code on my Komatsu PC120-11, and now the engine won't start at all. Has anyone run into this code before? I'm not sure if it's a sensor issue, wiring problem, or something more serious. Any advice on where to start troubleshooting would be greatly appreciated.

After cleaning everything up and fixing another leak, I noticed oil starting to seep around the pump after a few hours of running. It almost seems like the O-ring or seal between the pump and front case is failing.

Looking for some advice on a strange issue with my Cat 420E backhoe. The left outrigger handle feels completely locked in place, like it's mechanically jammed, while the right outrigger lever moves smoothly and operates normally. I already checked for obvious debris around the controls and tried...

I am looking for some help with a strange issue on my Kobelco SK300. The machine wants to slowly walk by itself and won't stop unless I pull the engage/safety lever. As soon as the lever is up, it stops like normal, but with it engaged, the tracks keep trying to move on their own.

I came across an ARTEER QB-480 at auction recently and got curious about it. I don't know much about the brand, but the machine actually looks pretty decent from the photos and specs. I'm wondering if anyone here has real experience with one before I decide to bid.

I'm looking into using VeriTread for the first time to move some equipment, and I just want to make sure I don't mess anything up or overpay.

Working on a Caterpillar D3B and need some quick advice. Where can I find a top carrier roller or confirm the correct part number? Also, I noticed a bit of oil inside the starter (near the flywheel gear). Is that normal for these machines (wet flywheel?), or should I be checking seals or...

Hey guys, I just picked up a non-running CAT 730 about an hour away, and I'm trying to prep for the haul. Does anyone know if these will roll while the engine is down? If the brakes are locked, what's the simplest way to release them manually so I can get it loaded without making a dozen trips?

I've been hearing a lot about Rouse Services and how people use their reports to check used heavy equipment values before buying or selling. Supposedly it gives you a solid idea of what machines are actually worth based on market data.

I've got a Kobelco SK135SRLC-1E excavator and just replaced the CPU controller. Install went fine, and I was able to do the minor adjustment, but now I'm stuck on the A adjustment. I can't seem to find clear instructions anywhere, especially for the part involving the stepping motor and fuel...

Hi everyone, just wanted to ask for some advice from those who have more experience with these machines. I have a CAT 320D excavator that recently started having slow or sluggish hydraulic movements. The strange part is that the diesel engine runs perfectly, good power, no smoke, no unusual...

If you want to change the control pattern on a Cat 305E, you can usually do it through the machine's monitor / electronic module settings - no need to mess with hoses if the feature is enabled. What you can try: Turn the key to the ON position (don't start the engine). Use the monitor panel...

If the start button on your CASE SV300 isn't flashing and the machine won't start, it's usually something simple. First thing I'd check is the battery - low voltage or loose terminals can stop the system from powering up. Also, make sure the seat bar is fully down, the parking brake is on, and...

I'm looking at a few mini excavators on Boom & Bucket and they make a big deal about their "regional inspections." Does anyone here actually have experience with this?

I've been researching different places to buy used heavy equipment lately, especially excavators, and I keep seeing people mention Boom & Bucket. I'm trying to understand what really makes it a popular choice among contractors. From what I've noticed while browsing, their listings usually have...

Has anyone here tried window tint on their grader? Does it help much? Also wondering if you lose visibility while fine blading or plowing snow at night.

When I raise to high idle, pressure returns to normal. Cold pressure checks are just within spec. Other gears stay at minimum spec. Could this be piston seal/internal leakage, or something else? Anyone seen this before? Thanks

If your Volvo A35E brake gauge is jumping, it is usually a sensor or wiring issue. Here is a simple checklist: 1. Check the Sensor Swap it: Try swapping the front and rear brake sensors. If the problem moves to the other gauge, the sensor is bad. Inspect: Look for moisture or "green crust"...
