Back in 1978, I witnessed a 1266 or a 1466 working hard in mt morris, Michigan beecher school district . The machine was trenching for 102 or larger concrete storm sewer pipe , A Volkswagen could have easily been driven thru the center of that pipe that was being laid . i was about 11 years old . What a treat to hear and see that monster bucket and machine at work. I wish i could go back in time and witness the moment again.

How did you like the 1266? I would have loved to have been able run one.

[@rp1645]

Hal I always Dreamed about running the 1266 they used on a ass too a metro outfall. The land digging. It had the bucket that filled these smaller mining dumps they used. Bucket to big for 12 yard dumps. They hauled I'll the dirt out. The pipeline was under a right of way road. It was always so interesting how they used the button or little push switches on the Dipper and bucket. The 1266 is sitting all apart in the contractors bone yard, with all the other equipment.

[@MrSwampdawg47]

I understand this might sound a little far fetched but, my grandad bought a koehring from the Atlanta area after it finished up on a pipe job. I wonder if it might be the same one…

[@tristenklein5940]

@@MrSwampdawg47 We ran a 1066 installing golf course irrigation mains and drainage tiles back in the early 80’s, there was nothing on the market at that time that could beat its productivity, quality of machine, maintenance and reliability. The Isuzu Engine was superb in fuel efficiency, reliability, performance and quiet, sold the machine in 2018 and it was still running strong.

I was a mechanic for 30 years and started working on Koehring in 1968 till about 1987. Worked for The Earle Equipment in Romulus, MI. Then moved to Texas where I worked for Waukesha Pierce both of these companies were Koehring and Bantam Dealers. Bantam was a division of Koehring. Best days of my life. And yes the controls were a little hard to get used to.

This is really cool and brought back great memories from my early years when I was a machine buff. I remember the first time I saw a kohering 1466 on a sewer line project where I grew up and I was in awe at the size of that machine. The bucket cylinder diameter was absolutely enormous. Needless to say I was impressed. This is terrific to see this footage, never new it existed. Thanks for posting 👍😎

My father worked as a computer operator in the Concordia plant in Milwaukee from the early 1970s into the 80s. I remember seeing this film at one of the family day events the company held out in Oconomowoc, then being bussed out to the proving ground to see the full product line of Koehring, Bantam, and Loraine lined up. Pretty overwhelming for an eight or so year-old engineerling.

Remember encountering a very large Koerhing 1466 back in 1982 & 83 in Boston on a subway relocation project.

[@jdizinski]

Thanks Jim great video. My father-in-law and I used to watch the 1466 everyday on the way home from work. It was the Camden County New Jersey municipal sewage Authority project in Southern New Jersey. The name of the company was Cruz Construction. We never saw a machine with that type of reach the setup was extraordinary. Again thanks for posting this video

[@Ratdaddy78]

In the early 90s I worked for a company that had a 466 and a 666 Koehring. Both machines had a huge number of hours, but their combination of weight and reach kept them around for deep bridge footings. Someone at some point goofed when they worked on the swing controls, and for a while the 666 was a Killdozer, it would stick in swing and the air controls wouldn't stop it. Having a 50-ton machine in close quarters suddenly turn into a spinner is a bowel-loosening experience. The usual way of dealing with this was to jam the dipper back into the trench when you came around again. I dug out the manual and found that the air control cylinder and control lever were mirror-image assembled. Once this was corrected, no more spinning. A little too late, because a week or two later the swing gearbox catastrophically failed. The crash stopping had broken a chunk out of a gear which found its way between two other gears. I think the only thing that didn't have to be replaced was the swing pinion. Anyway, those two machines did close to thirty years of good work. The people who manufactured, sold, and serviced them can be rightfully proud.

Cat 977 track loaders we're everywhere back then too, that is a rare machine to see nowadays. I remember so much equipment I loved that is all gone now. The John Deere track loaders with the backhoe attachments, and Barber Greene bucket wheel trenchers.

[@GitarCarl]

The variable volume pumps gave the 66 series onwards a fluidity of motion unlike every other excavator I saw at the time. Presumably the operators could get used to the slight unpredictability of how fast a particular motion would be. Thanks for posting this great video!

[@larrydunlop378]

Seems like the unpredictability came from the air controls possibly moreso than the variable volume pumps? There was some times a delay with those. Then throw in condensation and winter ! oh boy! LOL

[@williamhall9204]

Absolutely awesome video Jim. Thanks for posting it. The Koehring 1266d is my all time favorite excavator. I watched one working in NJ meadowlands digging a 40 foot deep pit as part of a waste transfer station project. That project took place in the mid 1980’s.That machine was a real beast. I’m pretty sure that a fully spec’d out 1266d had a 266,000 lbs.operating weight. As you know Jim, Koehring produced the even bigger model 1466.The 1466 was available as a front shovel or backhoe configuration. The operating weight on the shovel was 308,000 lbs. and for the backhoe 292,000 lbs. Thanks Again.

Awesome video Jim. Watched a 1266D working way back about 1978 working on a large sewer job in pickering , Ont. I was in awe and couldnt believe the size and sound of it. Then on the 1266 became my favorite excavator. I was lucky a few years later to get to run the much smaller 466D but the sound of the Detroit and the thumb button air controls gave the feel of its much larger sibling. That is one great video and ive already watched it many times and will many times more.

[@maplemanz]

I ran a 666 with the air controls and absolutely hated em .

[@larrydunlop378]

@@maplemanz These D series Koehrings were some of the first machines to get away from large levers with Hydraulic valves under the cab floor. So it took noise and heat away from the operator. (Even though they had Detroit's!). Also much much easier for the operator to run all day. The problem with the air controls is they became problematic in the cold weather due to moisture in the air. Very advanced machines in the 70s.

[@Romans--bo7br]

@@larrydunlop378.... that's what air Dyer's are for.... they were & are, a "Gods send" for the truckers. Too bad that, that technology hadn't quite been perfected yet, at that time during the 70's when these machines came out... though, by the early 1980's air dryers were fast becoming commonplace on diesel powered trucks... and certainly could have been very easily retro-fitted onto pre-existing heavy equipment, as they were on semi's and other trucks.... and certainly would have been a "salvation" in the colder temps with regards to air-controls and any other pneumatic controlled or powered equipment or accessories. I worked on a large pipeline project back in 1983, loading under a Koehring 1466 which was purchased new for the project.... what a machine!! Loved hearing those twin V12-92TA's (680 hp each... according to the operator.. if, I remember correctly... pretty conservative rating for those engines).

That's quite sad, especially as years pass there are fewer and fewer people left who have worked for/with the company or its products. I'd like to compose a timeline of their excavators and put it online, i.e. when the different models were introduced and how many years they were in production. Also what was the operating weight of each model. I wonder could anyone help me sourcing the information needed.

Say what you will but no one came near what the 10,12 and 14 could do production wise in that era. The sand mine my uncle ran got a new 1066 and I remember being in awe of that thing and it ran at that mine for over 20 years.
