I'm getting an E03 code on my 2009 Komatsu D39PX-21A dozer. The code only comes on after the machine has been running for about 1-3 minutes. It never shows up while the machine is in park, no matter how long it idles. The dozer runs strong, doesn't bog down, and doesn't go into limp mode. Has...

For mixed fleets, CAT often gets the nod because of its reporting, telematics, and integration capabilities. I'd be interested to hear what others are using and how well it's working in the field.

I recently changed the transmission oil on my Caterpillar D9G, and now the machine won't move at all. Before the oil change, it was operating normally. While researching the issue, I found a similar case involving a D9H where the problem was traced to a dirty priority valve and a faulty pressure...

If the problem only shows up when the transmission gets hot and low pressure drops below spec, I'd start by looking at the charge pump and checking for internal leakage.

I recently set up my Komatsu PC360-11 for a hydraulic hammer by switching the return line to the auxiliary valve. After connecting a grapple bucket, the attachment works as expected, but the machine is now showing pump relief codes. I'm wondering if the issue is related to hydraulic settings...

Salvage equipment can absolutely be worth it, but only if you go into it knowing exactly what you're buying.

My Bobcat 773 lift and tilt hydraulics have suddenly started moving really slow. The machine still operates, but both functions feel weak and sluggish compared to normal. Trying to figure out if this is caused by low hydraulic fluid, clogged filters, weak hydraulic pump pressure, or another...

From a sustainability perspective, the impact is significant. Reusing existing materials can drastically reduce construction waste and cut fuel consumption since fewer materials need to be hauled in and out of the site.

Our Caterpillar TH350B suddenly lost boom hydraulic function while working in the paddock. The boom will not operate normally, but it works fine when holding the bypass switch on the joystick. A mechanic checked the machine but could not find the fault. Has anyone experienced similar Caterpillar...

I am having an issue with the swing circle on my Caterpillar 14M, and I'm trying to figure out if this is normal wear.

To be honest, the inspection reports and startup videos are what make browsing way too addictive

Mud and water exposure, steep terrain, heavy loads, and long downhill runs can wear things out way faster than expected.

High-mileage trucks that used to be "beaters" are selling for prices that would've bought a pretty decent truck a few years ago.

I've talked to operators who loved mining for the pay, and others who left because the schedule and environment wore them down after a while

I've been browsing Boom & Bucket pretty regularly lately, and honestly there seem to be some surprisingly good deals popping up if you watch closely. I recently saw a low-hour skid steer listed way below similar machines on Marketplace, and it got me wondering what other people here have managed...

I'm having an overheating issue on my Komatsu PC200-5 with the 6D95 engine. We already checked the engine, adjusted the hydraulic pump load, and even replaced the engine with a spare, but the machine still runs hot. After removing the cylinder head, we found white marks/patterns on all 6 pistons...

I am looking for some help/insight on a John Deere 490E stalling issue I'm dealing with. The machine starts and idles fine, but as soon as I run any hydraulic function all the way to relief, the engine bogs hard and stalls. Here's what I've checked so far: Getting 5V at the pressure and angle...

You might see small dips here and there, but I wouldn't wait for a big crash. It's more of a slow normalization than a price drop.

Biggest headache? Coordination. One late delivery or a machine going down can throw the whole day off.

For me, leasing made sense when cash flow was tight or jobs were unpredictable
