67RModel

Dont think so Bob. The DM frame has a much deeper web section of the channel and changes dimension significantly just ahead of the front drive axle. I'm not sure if the DM frames are splayed like the R model's are. So in short the frames themselves are very different. Could you make an R model cab, hood, and other components integrate onto a DM frame? Maybe. I think you will run into too many fitment issues. Practically my answer to the OP is "no".

Just go on Muncie’s website and use their PTO builder. Over a dozen options https://www.munciepower.com

Yes tubeless 24.5 rims will fit on your spokes. However, 11.00-22 tube type tires are still readily available. Check simpletire.com. They have a sumitomo and a chinesium brand in stock.

Kind of a shame given its relative rarity but I guess you cant save them all. I'm just happy I found a nice one a little while back and was able to save it. Mine has a V8 screamer in it though. I almost decided several times to drag this one home since it was close to me but I refrained. I guess mine is worth a few pennies more now 😂.

I saw this browsing Marketplace. No affiliation with the listing. Looks like a super nice little truck. Windshield needs some love. Can't beat the price either. @Joey Mack how far is Marion, NC from you? LOL. https://www.facebook.com/marketplace/item/1208157969832910/?ref=search&referral_code=null&referral_story_type=post

I saw this browsing Marketplace. No affiliation with the listing. I think a Mack B77 is a supercharged Cummins 335. Has to be a pretty rare beast. They say its all original so definitely probably worth the asking price if its not rotten. Certainly not your average B model here..... https://www.facebook.com/marketplace/item/737653184823210/?ref=search&referral_code=null&referral_story_type=post

Have you sent into the Mack Museum yet to get all the build information and data for it yet? The big packet of information they will send you is neat to have. It will tell you all the specs on how it was ordered, who ordered it, etc. They will provide all the serial numbers of the main components so you can tell if its a "numbers matching" truck. Not that any of that really matters but its just neat to know the history of the truck. Beast part is the information is basically free. They ask for a small donation but its not required.

Built in the Hayward, California assembly plant. They had some small differences and model designation numbers. Some of them had aluminum frames. Built for what the West Coast desired at the time. Most of them had Budd wheels in lieu of Daytons. Battery boxes were different. Things like that.

I don't know how old you are but if your first set made it 22 years there is a good chance that this might be the last set you will ever need...I guess that is one way to look at it. Not sure if its a positive outlook or not? LOL

There's build numbers published on this but I think a lot of R700s were built with Mack or Detroit V8s. Lots of "vendor engines" put into the 700 series R models. I think the holy grail would be to find one with a 1693 Cat or the big, purple Allis Chalmers engine if such animals were ever built....

I wonder what he means about the 12spd? "can hard drive"? Does that mean he cant drive it or its hard shifting due to a malfunction?

This is what the Facebook listing says for anyone who can't access it:

I don't think so. 6.0 Powerstrokes were mediocre at best bone stock or not, and 2003-2004s were just plain awful. EPA required lower emissions and Ford/Navistar were either not up to the challenge or just plain lazy. So many failed fuel pumps, blown head gaskets, failed EGR coolers, and hydrolocked engines. Really just plain junk. Any engine that needs $12,000-$15,000 worth of aftermarket "bulletproofing" or modifications to be made "good" is a literal boat anchor in my book. The best part was Ford/Navistar engineers know the engine had many design flaws and put it out anyway. Then came the 6.4. An even bigger POS. 2003-2010 was not a good time at all for Ford diesels. Speaking of 6.0 Powerstrokes and Insanity, check out the link below to a 2004 F450 that just sold on Wednesday on the auction site BringATrailer.com. Granted it has been in storage its whole life and only has 13 miles on it but some whacko literally paid $55,500 for it. BringATrailer typically has sky high prices because they sell mint condition classics and low mileage quirky vehicles. I don't know what the buyers fees are for that auction site but its typical to have a 10% buyers fee. So he possibly paid $61,000 for a 2004 F450 with a 6.0 Powerstroke. Bahahahahahahahahahaha. https://bringatrailer.com/listing/2004-ford-f450/#comments-anchor

I dunno. I can smell the cheap Chinese paint and packaging of that thing through the computer screen. I think I would rather stuff around with lighter fluid and binders than to put 125 psi in that tin foil pressure vessel. I wouldn't trust that PSV, the welds, or the tin foil that thing is made of.

I know this is non constructive to this thread but why are Mack ECMs essentially bricks until the dealer does something with them? Why is nobody in the aftermarket able to program them? I know there are dozens of reputable outfits and people that will take a Detroit DDEC III, or DDEC IV ECM of about the same era as this truck (DDEC IV) and make the engine do whatever you want it to do. It seems like with with Mack you are painted into a corner if something like this comes up.....

I went onto Muncie’s website. Using their PTO builder they show at least 12 different PTOs available for the Mack TRL107 transmission. Left or right side opening. Tons of options. They even offer them in cable shift electric or air shift models and reversible models. Divorced or coupled….. https://www.munciepower.com

Already have. like everything they are an insane price now. Was hoping to find a set in a salvage yard if I do end up making the switch.

The actual objective here is just about entirely the cosmetics of a wider tire. Actually its a very stupid endeavor to pursue considering the initial cost of new/used 22.5 hubs, seals, possibly bearings, 9.00x22.5" dayton wheels (almost non existent), and new 315 22.5 tires. Plus the continued cost of replacing 315 tires vs 11R24.5 tires. If you look at the close up image of the front wheel area of my truck you can see it looks kind of silly since the wheels are set so far in (or the fender so far out). A 12R/24.5 is only 0.2" wider than an 11R24.5 but about 1.5" taller. A 315 is about 1.5" wider than an 11R24.5 tire. I'm guessing the rubber fender extensions create or compound the appearance problem. I considered taking them off but I don't think I have ever seen an RD without them. I should probably just forget about it and leave the money in my pocket....lol

Sounds like they owe you an engine. I mean correct me if I'm wrong but it sounds like the engine failed as a result of bad workmanship. There is not really enough context here to determine who fixed the engine and/or who ran the engine to failure??? What happens when an injector cup fail(s)? I truly don't know. Does fuel get pushed into the coolant and cause the engine to overheat or does coolant get into the cylinders and wash the oil off making its way into the oil? I'm guessing fuel gets pushed into the coolant since it at a much higher pressure. But it sounds like you have bearing failure which would indicate the oil was compromised.

I am just seeing this now. I have the same transmission in my 67 R model. Straight 5 speed. Direct in 5th. I bought it as a dump truck. There was a PTO / divorced hydraulic pump (old style) with a small drive shaft connecting the two. I removed the dump body and pump.....long scrapped. The PTO is still hanging off the side of the transmission. I have no use for it. I can remove it and send it to you if you want it but like I said its the old style and you want the newer style coupled unit. Either way I have a PTO for that trans. Not sue of the tooth count on the PTO gear. My guess is it would be fine for a hydraulic winch. Depending on what brand/type of PTO it is usually the drive gear can be removed and changed to achieve different running speeds of the PTO.

SimpleTire.com has two models of 11/22. A Sumitomo ST508 all position for $752/each and an MRF brand (Chinese I think?) lug type tire for $480/each. I'm sure they are cheaper online but then you probably get raked over the coals on shipping 10 of these monsters. I would just check with a local commercial tire shop first.

I'm sure this was announced on TV news. I don't know since I don't watch but maybe it wasn't?? Incase it wasn't, the US Senate has released its final report on the origins of Covid19. Report comes from the BIPARTISAN Health, Education, Labor, & Pensions Committee. It says what most sane people thought the whole time: Covid 19 was most likely leaked from the Chinese Wuhan Laboratory of Virology........ Surprise. Surprise. The Yahoo news link summarizes the report as well as provides a bunch of other good information relating to how this was suppressed throughout the pandemic. The actual senate report from Senate.gov is also linked if you want to actually read it. Its really very sad that everyone who said this back in early 2020 from the President to highly credentialed scientists were silenced and called conspiracy theorists. https://www.yahoo.com/news/no-one-believed-covid-wuhan-204950096.html https://www.help.senate.gov/imo/media/doc/report_an_analysis_of_the_origins_of_covid-19_102722.pdf

So I guess to recap, weight ratings aside, since I have 11R24.5 tubeless tires and wheels on my front spokes I would need to seek out the smaller spokes that will fit my front axle spindle and bearing sizes. The smaller spokes meant for 22.5 tubeless wheels/tires. Basically what I am hearing is wheels for 24.5 tires cannot use the same spokes that wheels for 22.5 tires. Once I have those spokes installed its just a matter of getting 9.00x22.5 dayton wheels (rare) and some 315-80R-22.5 tires.......I guess I need to call or go see Barry at Watts to find out what part number a 22.5 spoke for my front axle would be. He helped a good friend of mine switch an 88 R model rear spokes to hub pilot a few moths ago. He was able to find all the seals, bearings, and hub part numbers in a few minutes and the parts were only a few days away.

I found an older posting on here from back in late 2021 a guy had everything for sale. Spokes, bearings, wheels with 315 tires mounted and all the wedges and lug nuts.....for $200. I texted him a few weeks back (its been over a year since he listed them).....he scrapped it all.😌 LOL.

Right on. The gubbermint gets their cut before you get the keys.
