Has anyone used dual-wheel, articulated Case IH Steiger tractors for pulling pans? I’m interested in common engine, transmission, rear-end, and hydraulic pump problems, along with typical service life in operating hours.

Can someone explain the main differences between the CAT 12G and 120G, as well as the CAT 14G and 140G? I'm especially interested in changes in size, engine, hydraulics, and overall performance.

My 2005 Nissan 50 forklift has a 2.5L four-cylinder EFI gas engine and seems to have a fuel starvation issue. The fuel pressure is only 26-28 PSI. What should the correct Nissan forklift fuel pressure be?

My CAT 120M motor grader with a 6.6 ACERT starts and runs fine when cold, but won't restart after shutdown at around 170F. The fuel rail pressure only reaches about 2,500 psi during hot cranking. What could cause this CAT 120M hot-start problem?

I need to access the broken radio antenna on my CAT 420D. Does anyone have tips or an illustration for removing the cab headliner?

My John Deere 450C transmission was rebuilt with new parts. It pulls fine for 30-45 minutes, then slows down and stops pulling. Transmission pressure is about 180 PSI. What could be wrong?

We had the TCU repaired on our JD 450J, but the calibration failed at the decel sensor. Does the 450J require JD software or a JD technician for calibration?

We use a Hitachi EX-300 for jackhammer work at a stone mining site. We currently change the hydraulic oil every 800 hours using Total Azolla ZS 46. Should we change it sooner or can we extend the interval?

I'm a new heavy equipment operator with a Volvo L30B wheel loader. I need to replace the oil cooler but can't find the correct part number. Does anyone know the right part number or where to find it?

My 10K series machine ran fine the day before, with good oil pressure and no overheating. The next morning, the engine was locked up. The hydraulic pump and torque converter turn freely. I’m checking the oil pan next. Any ideas what could cause this?

My machine sat all winter and now won't move in the lower gears. It only moves when starting in higher gears. I'm also getting speed sensor fault codes. Has anyone had this problem before?

I recently bought a 2007 Case CX80 excavator with one-way hydraulics and want to add a hydraulic thumb. Has anyone installed the 2-way valve? Did you use a kit or source the parts yourself, and what did the upgrade cost?

I'm having starting issues with my 2004 Cat GP45K propane forklift. It seems like it's overfueling, and it will only run if I slowly feed it fuel. I'm wondering if the regulator, fuel solenoids, or another fuel system component could be causing the problem. Also, what scan tool do I need to...

My machine flashes a 2-long, 6-short glow plug code and shuts down when cold. After a few starting attempts, it runs normally. The problem comes back every morning. Any ideas?

The engine still runs, and the stereo, instrument cluster, and four-way flashers work, but everything else has lost power. I checked the fuse box, & only about half of the fuses have 24 volts with the key on.

I'm having a no-start issue with my Komatsu GD705-5 grader. The engine cranks over normally, but it won't fire up and run. I've checked the batteries and basic connections, but haven't found the problem yet. Has anyone dealt with a GD705-5 that cranks but won't start? Any suggestions on what to...

I'm working on the bucket linkage on my Komatsu PC200 and found that the main bucket pin is worn. The stick bushings still look pretty good, but a new pin is over $1,200. Has anyone had a worn pin welded up and machined back to size, or is it better to just replace it? Also curious if...

CAT 938G intermittently stays stuck in forward even when shifted to neutral or reverse. No ET codes, and it shifts perfectly when the issue disappears. Moving the steering column or parking brake handle sometimes changes the fault, so I'm leaning toward a wiring or connection issue. Already...

My 1972 Case 450 dozer loses pull on one track once the transmission gets hot. Low pressure drops below 40 PSI, but the torque converter pressure stays normal. Could this be a weak charge pump, leaking clutch pack, or worn spool valve issue?
