    Where does the transmission fluid disappear?

    It has to be going somewhere. Have you checked other systems for overfilling, that would indicate bad seals allowing transmission oil to transfer?

    Genuine VS Chinese parts

    That may be so, but you're paying for QC and warranty that just won't be present on a Chinesium Amazon-special part.

    Big dozers

    D11s are totally adequate for the copper mines down here. If more capacity is needed, they'll either put a second D11 on the job or pair it with a D10.

    Missing Oil Fill Cap

    @kshansen It was indeed a Lenz 557. Thanks for your help!

    259D conversion to mechanical bucket coupler?

    236D and 242D in my case. These were cleanup machines on mines, and saw frequent attachment swaps. Frozen mud seemed to accelerate the electric coupler failures.

    Missing Oil Fill Cap

    That might actually be exactly what was originally installed! I'm waiting to hear back from a vendor, but a whole Lenz kit including screen and retention chain is only $35 so I might as well order one.

    Missing Oil Fill Cap

    Pretty much exactly what it says on the tin. I think I loosened it with my boot and it flew out when I hit a bump. We were working in a 200' long drift with several inches of water in much of it, walked it a few times, no dice. I finished mucking, parked the machine, and zip-tied a rubber glove...

    Case580n Idles good but won't accelerate

    When you say accelerate, do you mean it won't go into gear or won't throttle up when in neutral?

    Cummins Fined $1.6 Billion Over Allegations It Outfitted Dodge Rams With Software To Cheat Emissions

    They still haven't figured out that throwaway junk is the worst for emissions and material waste. Want to save the environment? Build reliable products that aren't ready for the torch after a year. I'm looking at you, 777G. My other job has five of the things and on any given day maybe two are...

    Sarah Merget

    Hi Sarah, I'm HardRockNM. Hard rock as in hard rock mining, not music. I have developed a shallow understanding of creating unengaging content that misinforms viewers about the realities of mining. Namely by insinuating that it can be profitable; in reality a mine is a hole in the ground into...

    calling out the Deutz vatican

    I run a couple of Deutz 912Ws with large accessory oil coolers for torque converters and hydrostatic systems. All are located downstream of the jug fins and engine oil cooler, and see severe underground production service. As said above, you're overthinking it - the temperature of cooling air in...

    CAT 226/8 Opinions

    Two replies that firm is a sign to look elsewhere! I won't consider a Bobcat since I hate foot controls, Case is a contender and we have a good relationship with our local Case dealer. I haven't heard much bad about the 1845/1840/1835, how about the XT series?

    CAT 226/8 Opinions

    I'm looking at a CAT 226 or 228 as a general utility machine and a backup loader for when our LHD is down or busy. What issues are these and the 3034C (one guy I work with calls them Perkapillars) known for, and are they generally dependable? My CAT skid-steer experience with other companies is...

    D5h

    I've got no experience with a D5H, but start by lubricating the linkage. If it has grease fittings (seen in controls on some older machines), use grease. Otherwise try a penetrating oil or sprayable grease.

    Earth Moving Equipment

    You could write a book just on the hard rock side, and never even get into underground coal equipment.
