I have a Bantam S588 crane that works great but needs new paint and decals. Does anyone know where I can find replacement decals or matching paint?

I have a 2003 Cat 312C and replaced the throttle motor and cable after the old cable melted. The throttle works, but the RPM does not increase smoothly. How do I calibrate it?

After a few hours, the swing gearbox case fills with oil and comes out of the breather. The next day, the oil level is almost normal again. What could cause this?

My John Deere 544K has 2,235 hours and was used on a salt project. After fixing corroded plugs, I now have DEF tank header and NOx sensor communication codes. Could corrosion or wiring be the problem?

I have a 2009 Terex RT530E-2 that stops scoping in or out when the joystick is pushed to full position. If the joystick is returned to neutral, it works again. Has anyone experienced this issue?

I'm working on a Cat 12E with a D333 engine and need to remove the camshaft. The hood and radiator are already off. Are there any special tools or pullers needed, or is there a standard procedure for removing the cam?

I'm looking for the wiring connection for the Cat 140H wiper motor and wiper switch. If anyone has a wiring diagram, photos, or can explain how the wires connect, I'd really appreciate the help.

My 1990 Komatsu PC220LC-5 excavator has gone through two 24V 35-amp alternators in the past year. A technician said the alternators were being damaged by a short to ground. We found the oil level sensor was causing a ground back to the alternator.

I've seen a few really clean excavators lately. It's always interesting to see low-hour machines and well-maintained equipment pop up for sale.

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...

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...
