U models were available in '64 and R models started in '65. my grandfather had three '65 R402's with 402 flathead continenals and 10 speed ''mud stick'' overgears and one R410 with a 413 Chrysler industrial and an 18 speed baby quadbox. Chrysler would outpull a lot of trucks on the road especially with the doble overquad but you needed stock in exxon to keep fuel to it. still have the 413 out of my B model, was thinkin of puttin it back in anothe B model with a quadbox and a set of headers and dual exhaust! Matt

i bought a pair a few years ago off ebay. not sure if they are original or repops, they have the little r next to the Mack but the whole logo looks smaller. might be legit. on a similar note, anyone have a pair of the Mack Bicentennial mudflaps with red, white and blue colors like the Duck had on his R700 in Convoy? would like to get agold of a pair of those. thanks, Matt

dont really know, has whatever was in it when i got it. was gonna run it and get it hot and drain it and change it for the big 2 hr drive to springfield.oil looked pretty clean when i took the covers off so i figured id drive it and get it hot and change it anyways tho. Matt

yup, greased everything. took the linkage and side auxillary plate with the rails right off the side of the tranny and cleaned all the gunk out of the rails in the parts washer,greased both rails up then put rails back in the tower and bolted it back to the tranny and greased everything. just seems really stiff when cold but seems to losen up when its hot. was just wonderin if i screwed something up when i put the back cover back on but the fork went right in the slide and cover went right back on so i dont think i did. Matt

guess its pretty normal then? was just wonderin. after it warms up its sweet. driven a few quadboxes that were loose from the get go shfifting but were also loose all the way around! sounded like someone dropped a can of bolts in a few haha. had the back cover off and was just wonderin if i could have screwed something up and not gotten the fork back in right but it shifts like butter after you drive it a little bit. Matt

As you all know over the winter i changed the duplex transmission with a triplex in my B613T. took it for a ride and its one of the smoothest shifting transmissions ive ever drove in a Mack and also has absolutely NO bearing noise which i thought was a factory option in a B model. only problem is the auxillary shifting lever is very stiff, like you almost have to force it out of gear then it will float right into the next. as you drive it and it gets warmer it gets better . was gonna warm it up and drain the fluid as it has the old gear oil in it that it came with.before i put it in i took both the front and back covers off and the taddle tale plug out of the rockbox/tooth catcher on the side and found a tooth and believe it or not a valve keeper from an old engine rebuilt i guess someone lost it when the shifting lever was off? looked at all gears and none of the teeth were missing anywhere so i imagine the tooth is from a damaged and replaced gear years ago and they never got the tooth out. just wonderin, any thoughts on why it seems so hard to shift and get out of gear on the auxillary? thanks, Matt

ive seen them both ways and seen number ones with both 3/8 and 7/16 bolts in them . have also seen a # 2 transmission bellhousing on a trd72 transmission. i actually have one. Matt

sounds like the original transmission is in the truck and someone put the scania to it. probably pretty slow with a direct tranny and gas rear end gears unless someone changed them. Matt

got me all excited! thought i was gonna see a bunch of pics of Yaworski's end of the lind superpooch! havent seen that truck since it was brand new in macungie in 93

yes the hub was the same distance from the bolt flange back twards the block on all of them but the later ones were longer twards the front to accept more belts. the wrap around underneith mount in the first pic is from a r model or dm which bolted to the flat crossmember. b models used an i beam mount that was under the front of the engine not in front. and yes the water pumps are different with longer shafts along with some had more spacer blocks between the oil cooler and water pump. Matt

wow. why does all the cool stuff come around when im broke???

seen a few 67 serious transmissions in B61's behind 673 and was confused also. i know they were in b60, B62's and B68's for weight but thought they were only behind the diesels in B43's and B47's. Matt

Vinny isnt Doug's truck an H673T? or H633? something weird. im sure Superdog would know. i asked him about it one time when i was up there. didnt seem interested in ever parting with it haha .Matt

the front hub on the crank is different from thermodyne's to maxidyne's. looks like you have an early single 3/4 inch belt pulley on the crank from 53 to around 58 or so on the thermodyne. after that they changed to to a two hald inch belt pulley on the crank and the newer maxidynes had a 3 , 1/2 inch belt pulleys and a longer snout on the crank. most guys put the old thermodyne crank hub to put a maxidyne in a B model. it had nothin to do with the front engine mount. Matt

are they the ones that were built with all Dodge running gear? looks like a dodge budd hub rear end and front axle. Superdog would knowwould love to own a b firetruck project. Matt

yup, they deliver up the street from me. was gonna snap a pic of their u model last week actually. Matt

had a brand new driver fender for one of those. sold it tom kevin all a few years ago. came from Red Star express in utica Ny. they also had a few brand new cab back panels for B models that made their way to scrap before anyone got them. i think Red Sar express had a bunch of B65's and B67's. Matt

yeah what rob said or id just heat around the cast hanger and drive the bolt out with a punch. might have to go to Mack and get the ''shoulder bolt'' or body mount bolt as they are called. Mack used them on most suspension hangers and motor mounts after around 58 or so. you dont want to just stick a regular 5/8 th bolt back in there as the body mount bolts are made to center the component in the hole i believe. Matt

i think mine looks pretty good but too each their own. yes rust is an issue also and the lund ones needs some cutting and sanding around the top to get them to clear the marker lights. i think it depends on the truck also and the color of the truck. far as i know no one is sellin the aussie stainless type. Matt

now vinny you SAY youve been in your room for days researchin U models, the rest of us know the real story of what a 12 yr old does for days in their room j.k haha. i always liked the badge style emblem on that U and some early R models. believe they were used mostly on the off highway trucks. i think Superdog/Mike mentioned a while back he had one. Matt

237? how in the hell did the old timers ever get by with a sick old 673 natural and you guys are contimplating over 5 and 600 horse? geesh haha Matt

yup spotted that myself. that is one sweet old r model. we have about the twin to tat at work but was an old ryder rental truck with about 1.7 million miles on it. pedigred rebuilt engine and a sweet 9 speed rr. other than that the truck is junk haha. been rolled, windshield barely fits in cab, doors dont close, double frame is spread, hood has been fixed 5000 times but runs like a champ with dual straight pipes on the 300. Matt

yea i love the LJTB83SX model! love how all these people want big money but cant take five freakin minutes to figure out what model truck they even have! kinda feel sorry for that little blue B61 on long island.kinba suprised to see one of dennis meehan's trucks on there? thought they had no problem selling trucks overseas? Matt

well said. i looked over the pictures myself. i dont see a every bolt turned restoration. i see a really nice shined up, cleaned up painted RED truck. we all know red sells. it appears to be well taken care of and shined up really nice but nowhere near a 100% show truck. its show quality, not a show truck. i hope he gets what hes askin but im not seein it and dont intend to offend anyone. yes Mack painted over the airlines but that was production. Mack did not paint over all the wiring tho. Matt
