My 2018 Cat 315F LCR won’t go above 1,500 RPM, but auto idle and speed control work normally. There are no diagnostic codes. Could the recent DEF manifold replacement be related?

Looking for excavator manuals and repair information for an older machine? Manuals can make maintenance, troubleshooting, and DIY repairs much easier.

My Link-Belt 350x2 overheats when working hard. It also has weak swing power, and one track feels weaker than the other. Has anyone experienced this or know what could be causing it?

I replaced both speed sensors on my Cat D5G dozer, and the track issue is fixed. But now it won't go faster than 1.7 speed. Do the sensors need calibration, or could something else be causing it?

I recently ordered a new monitor for my machine because the old one stopped displaying accurate readings. The water temperature gauge only reads up to a certain point, the hydraulic temperature gauge no longer works, and the AES and travel speed buttons don't respond, even though they still...

My turn brakes seem out of adjustment. The steering clutches disengage when I press the pedals, but there's a long pedal travel before the brakes finally grab. Once they do, the brakes work fine. Where is the adjustment for this, and is there anything in the hydraulic system I should be checking?

My Cat 140H grader has lost forward gears 1 through 4 and reverse gears 1 through 3. Has anyone had this issue before, and what ended up being the cause?

I'm having a transmission issue with my 570A grader. It goes into reverse and pulls fine in all gears, but when I shift into forward, it only moves at idle. As soon as I give it some throttle, it starts jumping in and out of gear. Someone mentioned it could be worn cogs in the transmission, but...

I recently came across a D9G dozer that stopped moving right after a transmission oil change. The machine was operating normally beforehand, which made me wonder if something during the service could have caused the issue.

I am getting tired of replacing transmissions with reman units every time one fails. I'm looking into rebuilding them in-house and would like to hear from anyone who has experience with 9630 transmission rebuilds. Are there reliable aftermarket parts suppliers for these transmissions? Is there...

Has anyone dealt with a Case 650K stuck in forward all the time? Machine starts fine, but it keeps trying to move forward in F, N, or R unless the brakes are applied. Dash shows FNR correctly and there are no fault codes. Replaced relays, fuses, terminals, and even tried another drive controller...

I once ran a Caterpillar 740 during a really wet winter job moving dirt for railroad tracks near a biodiesel plant. The mud was terrible, but the 740 handled it surprisingly well. Worked night shift the whole time and honestly enjoyed running the truck, but those long muddy winter shifts are...

I'm having a strange transmission issue with my Caterpillar 140H and hoping someone here has dealt with something similar. 1st gear works every time, and 5th and 8th usually work, but sometimes I have to shift back to park first before they engage properly. 2nd gear is the biggest problem...

I'm in the middle of resealing the lift cylinders on my John Deere 550G and ran into something I'm not too happy about. On the left lift cylinder, I noticed the gland nut has a crack running from the outer threads toward the inside near the wiper seal bore. I attached photos because I’m curious...

Hey guys, trying to find a CAT 197-3818 limit switch for the armrest on one of our machines, but the local dealer hasn't been much help. Looking into aftermarket options-just want something that actually fits and holds up. Does anyone have a go-to supplier or website for these? Any issues with...

I've been looking into top-heavy equipment auction platforms like Ritchie Bros., boom and Bucket, and IronPlanet, and I'm curious what's actually working in 2026. Which auction sites do you trust most?

I've been checking out Boom & Bucket lately, and honestly, the listings look really clean and detailed, super easy to find what you're looking for. It actually makes the whole browsing experience feel smooth and a lot more user-friendly compared to some other platforms. For those who've used...

Hey guys, having an issue with my Caterpillar D6C winch. It worked fine at first, then only at high speed, and now it won't pull at all. The drum just free-spools like the brake isn't holding. I've checked oil level, flow, lines, and the screen filter-everything seems okay, but pressure might be...

I came across Xcira. From what I understand, it's part of RB Global and powers timed auctions and marketplace-style listings. I'm curious how it actually performs

My CASE 650K Series 2 dozer is leaking hydraulic fluid from the drive motor into the final drive and around the sprocket. Machine still runs fine, but I want to catch it early.
