No R686ST with six speed low hole, 38 rears, I think the blue one got a water tank mounted on it. It got left with the maxis released and roiled into a DM dump.

I'll have to check that out. I'd love to have it but I think it's going to be expensive. I did get this one, there were 3 all alike, but the others were kind of rough

I think the depths are the same , but I can't be positive about that. I haven't had a mack with a single plate clutch apart in like 40 years. Do you have the transmission you want to use yet? I've put roadrangers in macks that had double plate pull clutches like a spicer angle spring with the 2 inch input shaft. I know on one of them I got the parts from Tony DeSandro at Ace Auto Parts in Bensalem Pa. I know he knows what parts fit what. There is a guy Herman at US truck parts right outside of hazleton who is pretty good too, but english is his 2nd language so I do better just going to his place and talking in person. Both those guys are exporters so they deal with a lot of mack stuff

It was bought new by George Racho/South Tamaqua Coal Pockets with V8 mack power and being it was the early V8 they had problems with it. It went back to Craig Motors the Mack dealer across the street and somehow they agreed to repower it with a 1693 Cat. Sometime after George died, it got sold to Joe LaTona of Pittston. Joe passed a few years ago and the truck was sold again, but I don't know who bought it. The picture of it where it's red is actually in my back yard (I bought George's shop) the green picture is after Joe Latona restored it

Yeah for the CL50 clutch. The clutch brake was on the countershaft. You had to adjust that clutch by taking out shims when it wore down, then adjust the linkage, and then there was an adjustment bolt for the clutch brake. I had two like that that were 1960s One had a TRL107 trans and the other a TRXXL107 the two stick with the super low first. You found them in mixers a lot, they were great for doing curb pours. Both those clutches held up really well

Yeah I blew the picture up and it does look like fans. I'd love to see under the hood

Yeah, I seem to remember working on sixties stuff that were 3/8

Yeah they are. I used to stay in touch with Adelaide and her Husband Terry from Tulea, but I haven't heard from them in maybe 5 years. They always treated me really well. Tulea closed up, Terry said they had nobody to take it over, they must be well into their 70's now

I'm new to this thread. But why are you putting yourself through all this aggravation? Why not just fix whatever is wrong with your triplex?

Well if you are going to charge a one megawatt hour capacity battery pack in one hour, you need one megawatt of supply. If you want to do it in 2 hours you need 500 kilowatts. And I'm not even figuring on losses. Basically a 1200 amp 480 volt three phase circuit to every charger. And the damn chargers must have a transformer in them, so now you have a problem with "low lagging power factor". And they also have to have rectification to turn the AC into DC. so there is going to be a problem with harmonics. Just like the problems with harmonics we are having in the plants now that all the motors are on VFDs. It distorts the sign wave all to hell. Large data centers have the same problem because of the rectification in the computer power supplies. It's a dam expensive problem to fix. And it's not a problem that is contained in your facility. It gets so bad that it affects the power company's distribution circuits. You might be causing a harmonic problem, and I'm 1/4 mile down the road, and all of a sudden my electric motors start overheating. There are just too many problems, and we are talking on a huge scale

I'm really surprised they got enough cooling under the hood of a RD800 for a 3412. Every 3412 I've ever seen has a huge radiator

Yeah North American Engines had a 149 powered generator in a trailer and it was pretty loud, but I didn't ever have to be inside with it running. Those two 16V at Philly Police Headquarters (Roundhouse) were in sea containers and being inside with them running made it all so much more intense. Did you ever run a DA sander and it makes your hand itch because it's doing nerve damage? Well that is the same itch you feel in your teeth inside that sea can with a 16V running in it. But that isn't the point. The point is that those electric class-8 trucks need that kind of power to charge. If you wanted to set up a generator powered charging station, you'd need a 16v92 powered generator to run it. That damn tesla Semi has a roughly one megawatt-hour battery pack. So to charge it in one hour you will need a one megawatt supply. Have a location that you need 10 charging points, and you need a 10 megawatt supply, a truck stop will need their own peaker plant. It's just totally unworkable

That was from the 16v92 Detroit Diesel running under load. Have you ever been near one running? They make some serious noise 1t 1800RPM under load no matter if they are driving a generator, a pump or whatever And yeah I work on medium voltage switchgear now and again too. Most of the larger plants here have 69KV primary power dropping down to 12.5KV on the secondary side of padmount, and then down to 277/480 close to where the power is utilized. I've never felt it, and I hope I never do

I took their 4 axle autocar and a 4 axle Rogers to Parkersburg WV to pick up a Tadano Mantis back back in about 1986. Not too long after leaving Parkersburg I was using the jakes and the elbow blew out right below the muffler. Talk about screaming. By the time I got home my ears rang for a week

I just checked, it had a Cat 3412 engine in it. The story is that they wanted Carter Machinery to install it, and Carter refused, so they did it in their own shop. Carter Machinery is a super huge Cat dealer in that area

It's adjustable, if it's like the ones I used it's hydraulic. It probably uses the Fifth wheel that takes the large pin. Or like some I've pulled the pins were swappable. I think that orange DM800 that has the Bethlehem Steel on the door has the big fifth wheel on it, or at least it did when it worked at the mill. McHugh sometimes used one of these Cline Prime Movers that they built from off road dumps to pull trailers like that with the tall gooseneck

Yeah I remember Trap Rock. They ran all yellow heavy spec DMs, didn't they? I never knew they had a Mack Switcher. I'll bet JC McHugh would know what happened to it. That's pretty local to him. He's in the old Strick Trailer plant in Fairless Hills Pa. Railroad equipment is his business and he's into the antiques https://www.mchughlocomotive.com/

Famous truck in the Kentucky Coalfields. Crazy Big Cat power. I seem to remember it being a 3500 series industrial. The last I heard it was in pieces in MMI's yard

6-71 Detroit powered. It might have even been a 2 valve, I can't remember. I think it was 9 1/2 feet wide with the outside tires on

Pepsi Sacramento required upgrades to the utility substation and powerline to be built to run their chargers, and they had to install a Tesla Megapack on the ground. Those Megapacks are 1 Million dollars installed a couple years ago. The project took 3 years. Here is Pitt-Ohio's experience with electric trucks

If they are going to electrify at all, the only way it's going to work is diesel-electric hybrid. People have the impression that they can go to Home Depot and buy electrical supplies, amd find an empty space in their breaker panel and that would be enough to charge an electric class-8 truck. In reality for even a small fleet you are going to need a 1,000 KVA pad mount transformer installed at your facility. If you wanted one next week, you need to get a time machine and go back to the year 2020 and start planning. The customer side of that transformer would be a 1,204 amp, 480 volt, three phase circuit. Just to put it in perspective, I've worked on emergency generators for the City of Philadelphia that were rated One Megawatt. They were powered by a 16v92 twin turbo 2 stroke Detroit. Roughly 1,500 horsepower. If you were in the enclosure doing tests and you had it under load you could feel your bones vibrating and after like 5 minutes your teeth started to itch. Most places don't even have that much power coming down the street, you are talking about having to do upgrades all the way back to the substation. And lots of substations can't handle it and will need upgrades. Pepsi Sacramento's substation had to be upgraded to charge those Teslas. It took them 3 years to get the power. I could go on and on with the problems. The six pulse rectification to turn the AC into DC creates 5th and 7th harmonics on the powerlines that doesn't end at the property line, it effects other power company customers. The people making these mandates and regulations are way way out of their league. BTW here is what the American Trucking Association has to say about it

I haven't followed up on that much lately. I would imagine weight, and getting enough power into the facilities to charge them is a problem. It's not like you can just call up Billy Bob's electric and get him to install a 1,000KVA transformer to supply the chargers. That requires long term planning and in a lot of places 8 figure budgets

There is a place by Pottsville that handles all kinds of brakes for industrial applications. They have all kinds of odd stuff there, and do rebuilding of hydraulic parts, make control cables etc. They might be able to help get those hydraulic parts for that juice brake B85. They are in an old bakery building on if I remember right Bakery road. They got me some stuff for my juice brake Lancer Boss forklift that was made in Germany. I'll have to see if I can find the name of the place Found It https://www.airbrakeandpower.com/ Air Brake & Power Equipment Company, LLC 1048 Bakery Rd, Pottsville, PA 17901, USA

Years ago I had a single axle IH wrecker with the cab burned off of it. I got an R model with a broken trunnion. The R model frame slid right inside the IH frame. Spme minor shimming and it bolted together so nice with lots of overlap. I was tempted to not even weld it, but I did weld it some. That saved me so much work. If that hadn't worked out I would have had to change all the mounts for the crane and the body to make it fit the R Model Frame. Not to mention putting all the single axle suspension under it. I think I probably saved a weeks worth of work
