ditto on the pictures and story. looks like the R doesn't have AC . can't believe the R has built in extended cab vs add on sleeper. caught my attention due to I have a DM-800 in progress (1/25th scale) that has been given a built in extended cab. in between lawns etc cab got primer today.

someone pushed the temp probe tooo far into the core?? that's going under assumption the "new "iron still has that set up.

he's not playing with toys!!!he's doing his part to keep history alive.. sounds soooo much better when static from "other half" bout wasting time on junk ::LOL .

those picture show so much for useable parts . which may look like junk. as has been mentioned in earlier post ; many times easier to keep entire unit intact although not always able.

what did you use for batteries on start attempt ??? one 12 v/s 2-12v or other set up. with a s/p switch one 12 might not be enough unless using a over size 12 from a dozer or equipt type. trace the system .didn't see battery box/boxes .possibly two boxes on passenger side held 4 = 6 volt batteries at one time and changed threw out time.

if it is a 24 v starter for sure , before condemning the starter check wiring and between seats (or battery box) for a series parallel switch. may be 24 on start ;system will be 12 or 6 for running. push button signals = I like it.!!

only set back to trip to deerfield was I 84 closed westbound going to show. what closed the highway would be something from a comic book ;but it wasn't funny. a car went airborne through the roadside sound barriers high up with back half sticking out , with the amount of troopers on sine and cameras. someone didn't make it. I couldn't go back to driving in to days environment. everyone is preoccupied

sorry bout that proper name :: 70mackMB . JoJo didn't see you there today. must of missed you in crowd. LOL

weather wise perfect for deerfield truck show. was an honor and pleasure to meet and converse with MB70 and his son. had my Mack gold coin and forgot to show him.

truck is so different with the twin air/ front bull guard and highly impressed with lettering with shadow on door. unique is nice

Dang; that's an impressive "profile" ::B-815 to two DM800's to R-688!! I spent too much time wrenching vs driving. had a B-81 dump at the farm last yr , hoping to get running. go to work one day truck gone !! WTF. owner "oh I sold it . least he could have done was wait for day I was there so I could say "good bye " . did get quite a few hrs behind a DM-800 at part-time job. tri-axle no floatation front tires, pulling out asphalt plant scaled 84K it was a saturday boss said get all you can plants will be closing. the fun days , had a huge coal body came from down south .

started on craigslist CT under mack trucks; bounced around to NY // long island etc. albany NY showed the "53 LJSWS .I'm not good at this cut/paste stuff. if it wasn't for spell check I'd be in a heck of a situation.LOL

another way to build a set of install tools ; look in the scrap barrel for any bad bearings, cut the outer cage =throw out the rollers and keep inner bear piece; . extreme caution with hitting the harden bearing parts. installing a wear ring doesn't take a 20lb sledge; little RTV and even round the spindle tapping. stemco did make a spin within it self seal which required no install tools even tapping . I always lube the two spinning pieces before install whether C/r or stemco.

was always a stemco believer ; had at one time quite an assortment of the install tools :: in the dinosaur days when each seal had it's own drive tool ; before the blue tube and changeable heads. the grit guard seals were a big improvement for keeping crap out. technology came out with the spin within itself seals (C/R). bet not too many remember the stemco seals when the wrap was actually leather ?? based on picture; i go with a improper install with a hammer. in hardship cases , I have used the inner bearing for ring install, carefully tapping inner race with flat punch, huge metal washer found in the HD Mack rear wheels also worked for a tapping spacer. close tolerance on spindle / thick enough to tap on.

not associated with any adds posted; just passing on info. have no idea of each truck. 1-Albany, NY =='53 LJSWS //// 2- long Island ,NY B-40 mack headed to scrap yard possible.///// 3-Deerfield,Ma parting out a '40's FJ Mack /////4- Utica , NY "42 EF model 25 Mack. all above trucks on craigslist . adds found using Mack truck

some where along the way the 3 spin on set up with large oil pan was 51 qts ??? possibly that 51 was total capacity including filters. unofficially there was a problem with the large pans developing cracks , something with the manufacturing /casting process. brazing didn't work for repairs.

with the phasing out of generators the alternator of factory install was the Leese/ Neville (as pictured) , built in regulator on top cover . plastic cover screw removed take small screw driver to adjust voltage.

agree 100% ; alot of work tooo many differences. depending on your maintenance set up == time down ;; most important $$$$. look into making a RD unit. R with double frame must have been an RD from start???? is the DM that bad to use as donor ? rails are a challenge to change , .RD might have rails similar to DM , R models will be different

finally a positive sun shine for this weekend in new England ; hopefully the Deerfield show will still take place.

Autocars possible cummins power . another one famous for side panel removal were the IH's having gas power (545 ??). hot summer day leaving side panels on was almost a guarantee for vapor lock. on track now let's stay on track !!!😂

correct on extra pin setting. nice looking machine. 4 in 1 an invaluable asset to that or any machine.

interesting set up. don't see where it had a 5th wheel or dump.

not only looked cool but technically it helped engine run cooler. and driver didn't mind a cooler cab inside . keep in mind this was the day of mechanical common sense not computer modules shutting down a unit due to temp fluctuation ;; LOL

a real mack (B-model) could run in the pouring rain WITHOUT the hood ; only inconvenience was the fan blasting the rain towards the window. LOL been there done that. challenging for me to read all the electrical problems of todays iron;; but to have water create an issue. times are different.

have seen a number of times the complaint of rears over full .why won't top stay full!. not suppose to as stated . once had a customer trying to keep power divider housing full!! " it keeps going down" . after a rebuild, the initial three point fill =power divider / top carrier/ rear housing: level needs only to be check in rear housing.
