Yeah I never use my jake much either. I have a little hill in front of my shop, maybe 1000 feet long at most, guys jake down it with straight pipes all day long. Yeah it's a business district, but the speed limit is only 25. Me and the rest of the old timers here on the hill just shake our heads. They even jake down it empty. That being said, you can install a Jake on an END673, or even a Mack Dynatard if you change the cam

What do you pull with this tractor? A car trailer?

You know a 237 Maxidyne only needs 5 gears. Why not just put a TRL107 Maxitorque in it? Unless your rear is real low and you need an overdrive. 237 Maxidynes only came with either a 5 or a 6 speed from the factory

What engine are you using?

I had a float come apart on the steering axle of a boom truck on the Jersey Pike. It tore pretty much the whole right front fender off, ripped the brake hose, and it bent something I had to fix back at the shop, but I forget what. I wouldn't want to get hit by one Years later my buddy the same truck on the TP in Ohio and blew a float and he rolled the truck, Tore the Simon -RO 23.5 ton boom right off the truck. He had to kick the windshield out to escape. It was late at night and the first thing he does is call me with his adrenaline pumped through the roof, talking fast as hell in his Jamaican accent. Lots of Bloodclaat and pussyclaat lol

LTL9000 Ford, Big Cam Cummins. Yeah It's mine, Sitting in in my garage right now

Yeah I don't have much experience with locomotives other than some little 44 ton units, and were all HB600 Cummins or Detroit diesel powered. Truck engines really. My old employer had a thing for short lines. The "M" in SMS is for McHugh. I use to move a lot of MOW equipment and Car movers like trackmobiles with my Trail King trailer

Is that the one that has the turbo with a clutch to spin it up mechanically for starting?

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
