I don't know a thing about them,but around here,Granites outnumber every other brand of dump truck 10 to 1. Even most of the county road departments have been switching from Sterling and IH to Mack Granites.

I remember the truck . It was a short wheel base , yellow , S/A , shinny budds , H 63 . The guy had not been on the site in a few years . He posted a picture of the truck with new tires . I asked about the tire sizes and he responded . I think that was his last post . Wish the the truck was mine 

I think that truck ended up down under,Aust.or New Zealand

Lol. There ya go superdog 

you know the kind of the roads I have to travel then. Kinda sounds like highway 10 out of tahlequah 

we loaded west of Siloam Springs,turned of the highway a little ways and then turned onto basically a solid rock trail up to the turkey farm ,right beside a cannery of somekind.

I’m 50 miles east of Tulsa and a little ways west of Siloam springs Arkansas off 412. Rose Oklahoma near a little town called locust grove. 

loaded turkeys outside Siloam Springs one time,interesting trip down, was following another truck that thought he knew a short cut,I don't remember the highway # we got on south of Joplin,but we spent alot of time in the wrong lane to keep from knocking top row of crates off the trailer.

Relisting due to non-paying buyer.

if you cant find any close by,let me know,I have 4 or 5 dead engines I could rob the lines from.

the X and SX goes back to a different era,A RW713 was heavy duty,a RW613 was standard

285 Maxidynes with tip turbines were gold, 300+'s were that red color with the tip turbine as far as I know. kinda like a red 'Glyptol'color

300+ engines were originally copper,that reddish orange color was what they went with for all engines after they had to quit using gold paint on the Maxidynes,then came light blue,then gray

47255 would be most likely a 1964

The ENDT-676 came out in 1976 IIRC for either the 1976 model year, or 1977 model year. Mack dealer brought a new one out to where I was working and I asked him if it ran hotter than the 237 engine as I thought it had an additional radiator. Nobody laughed as they thought the same thing till it was explained to us. The original ENDT-675 engines were 906 foot pounds torque and the ENDT-676 was a whopping 1080 foot pounds!! Both produced maximum torque right at 1200 rpm. Both engines were a significant step up in power from the T673C, and 673E series. It seems the END673E series engine was about 540 foot pounds at 1400rpm, and the T673C engine was 700 foot pounds at 1500rpm.

Used to put a lot of duplex, and quadraplex transmissions replacing the TR-107 five speeds and recalibrate the governors as the driver's just didn't like the Maxidyne power layout. Was expensive on transmission maintenance behind those engines but I wasn't involved with the actual rebuilding, just replacing. I'd swap a trans and tack together the driveshaft, then pull it sending it into the driveline shop for finish work and balancing.

The 200, and 300 series transmissions are after I finished working on trucks so have known hardly anything about them.

Completely forgot the other conversion that was popular was a Fuller RT, or RTO-9509B with the "F" style top cover dependent upon axle ratio and tire size. This allowed placement of the shift handle further forward in the case. A small nine speed nowadays, but worked well in that application.

ENDT676 came out in '73,followed by the ETAZ673A "300 +" in 1975

I had a discussion with someone about this who had some documents with Mack that had conflicting numbers.  There were 14 CF719’s built with the twin turbo 864’s made. I have number 12 and the other guy has number 9.  His documents show that for the fire service it was boosted to 350hp.  I bet there are more than 10 running examples left since I know of third surviving CF and Tom has one in his R719. As for non-turbo, my F715 is on it’s third or forth. The first blew up on the first trip. It went right back to Mack to be replaced. Mike. 

I've got 3 864's that are runners,(B815,R615,&F715)and 2 more I'm not sure of,(B615 & F715),plus a twin turbo in the barn for a R719 I have that was repowered by a 237

Very good for age,stamped 1927 on inside cover,bulletins up in the late 30's,lots of info and diagrams.
