have bought number of items from H F ; also consider the quality of any product from all manufactures 30 yrs ago VS todays quality has changed considerably.

unique the spring pin shackle set up. I have/had similar setup on liner hold downs used for wet sleeve DD . 3 flat washer brazed together looked like rear view of maxi transmission counter shafts. one bolt the washers held two liners down. relooking at picture two -thought that was a liner tool not a liner with rod welded in middle. are those liners that short now or angle of picture. "new "liners don't go full length of cyl anymore ??? changing times.

now the big question and challenge :: what gets built first ==house or garage ??? understanding mate makes the decision so much easier; not many of those around based on experience, LOL brockway always had a nice style truck (before the mack cab )

should be able to find tires/rims having same bearing to fit the hand truck axle. economical way to have great hand truck

have taken the axle cut it in center = install a piece of proper dia pipe then reweld. gives you room to slide axle side ways for removal. number of places sell semi/pneumatic wider tires . company I worked for had many hand trucks being thrown away. I took a few and modified. tubeless with the green tire flat repair stuff works.

another proves you CAN teach an ole man new things.. never knew a RB had set back axle .. thanks for news/update.

are you insinuating biden goes to google first;; COME ON NOW !! we all know YOU have more knowledge then him,, NO need for you /google

steel nose always a better== B-70's/80's or DM 600/DM800. 800's duel purpose ;;;lunch time you had large table for lunch when using fenders. LOL . fiberglass the food slid off, not to mention can't sit on a fiberglass hood. spent number of lunch breaks sitting on DM800 fenders ( while polishing the HUGE hood).

where does the RB come from?? will admit I'm NOT up to modern day model identification . the RB is a ???? . R model with B model parts ??? another sign of the technical standards of today. days back a model number told a person what the unit was. can understand a ==example purpose ONLY R611T = R model 673T with RR trans single axle.. DM 685 S - Dump Mixer chassis / maxi eng/ light suspension ;; and so on ... !! this RB =ole man at a loss. don't even try to examine the newer model numbers.

brain cells at a loss. steel co :: NOT Chaplin/banks ?? Edgecomb steel (Milford) didn't have grapple cranes. this goes back to Connecticut truck book;; so many not listed that have gone by the way side.

glad it's posted as a "fun question" ! no offence can't see an acuate answer without more specifics. same as a question of "how drunk can I get with only half bottle of bourbon ?? 😱😂

YOU/(a person ) can do what ever individual capabilities are ! then it goes to shop/ set up/ access is .. can I is NOT the question ;;more over will I ?? that question has TOO many variables = 1= why do it/2- what for-- road use/ show machine /3- resources available ==list goes on. more specifics for reason why helps the BMT crew give response. first saw this RB model in another text , thought it to be mis print;;has shown up a lot . not sure of what constitutes an RB

685 ===maxi /5 speed???

don't leave the BMT crew in the dark with out giving up more pictures and specs=== vin / eng/ etc

I didn't notice that point till you wrote;; it IS a centered cab . NOT a DM steel nose. Still it's a Mack worth maintaining (they all are ),

NOT a long winded procedure but free knowledgeable advice from reputative source. have ALWAYS had respect for the Australian culture and it's people.so close on the globe yet so different in operations.

Hey ; what's this obsolite crap ;; LOL that's my age bracket . it's NOT obsolete == it's called vintage, nice lady at grocery store I get my coffee doesn't ask if I'm senior for discount any more ;;; don't know if I look that old or she is being nice.

that's one fine looking DM scale model. at present I have 4 models in build shop with another showing up yesterday (1/25th cattle trailer ).which I bought for grandson. found some older models in boxes at the house . model bought in '78 for $11.25 is $82.00 at hobby shop today. located some 11:24.5 tires in Canada (1/25th scale ) for $8.00 a piece = need 10 for one build.

= what was used to tow lowbed before Superliner showed up?? if there was another tractor. how do "two" units compare for specs- wheel base/ 5th wheel settings . first trip with super/lowbed- does that mean new to truck or new truck trailer combo ??

WELL you "high tech " mechanics have all the good toys to work with !LMAO🤣. bet you never did an engine rebuilt outside in a gravel bank = yep I did but can't remember why = some things are better forgotten. now a Polack having an engine on stand welding liners might go and cover the crank journals !! why ="cause that's what the book said to do. bet you didn't know the close relations between Polacks and red necks =when engine building ;;; had to stay on topic.!!!! LOL

would think it has a slider 5th wheel, easy check would be move wheel one way or other. post was put up on Thursday with unit going to mechanic Friday (yesterday); hope this has a follow up. noticed on many post placed on BMT forums NOT MANY update on results .

another quick option to crank cover would be one or two welding gloves placed in bottom of cyl. high tech would be piece of asbestos cover; for most welding gloves work. one wraps the journal another for added coverage lays on top of first in liner. easier to move cyl to cyl. also stick rod makes more sparks (does better on heat distribution?) wire feed not as messy challenge to get in cyl at times. lest we NOT forget how /where the ground is attached !

bad or broken engine mount should show a gear shift moving erratic . cruising 45-50 would be a "no strain "condition for drive train. engine mount/ rubbers wouldn't be under load to twist UNLESS the cruising condition involved torque. change the front tires with another set if possible or have those balanced to confirm they aren't the problem. had a brand new truck with vibration at 40-50 mph = turns out the balance weight fell of the rim == think I'm showing my age again. tires were bias not tubeless . also how is the word "bounce " used in reference to problem . truck bouncing up/ down or is it shimming at 45-50/ wandering ?? I agree with all above comments terms of 5th wheel set wrong etc. was the low bed empty or hauling a D-10!! (i know it can't just point of issue).

title shows B-67 ST indicating a concave cab twin screw. freight hauler operation ?? general over view of rear section is a positive ?? ; brakes / suspension decent indicating good Maintenace ?? as always on BMT pictures help a great deal

It's a machine there is NO way to ensure it keeps running. hoping you have received an honest history of the unit terms of servicing/ repairs made etc is a start. go with the basic same as a used car. change the fluids possibly take sample to sent out for analysis , send the masterminds on BMT a few more stats of the vehicle such as mileage/ hours ; do you know it's principle use before you purchased ??? job giving it more hrs then mileage ( road truck/ local delivery operation?? why "clean engine internally an issue?? blow by out breather when running ??? have a spare set of valve cover gaskets then remove valve covers check sludge under covers.
