I have a John Deere 344E and I'm trying to find out what bucket size it originally came with from the factory. I've heard some people say it was a 2-cubic-yard bucket, but that seems a bit large for this machine. Does anyone know the standard bucket capacity or have the original specs? Thanks!

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...

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...

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...

I'm trying to track down a hydraulic diagram or pump manual (PDF) for a Sumitomo S280F2 and am not having much luck so far. I recently got my hands on one and want to better understand the hydraulic system layout, pump specs, and troubleshooting basics before I start digging into any repairs...

Trying to troubleshoot my Bobcat 334. It was working fine, then suddenly the swing kept going one way, and now I've got no swing in one direction at all. All other functions are strong, no visible leaks. Could this be a swing motor, relief valve, or sticking control valve issue? Just trying to...
