When I had my drop axle installed we had to switch from a rear mount to side on a 12 speed trans,don’t remember my mechanic saying it was a big deal but next time I see him I’ll ask,sounds complicated to me..

1= a 12 speed may be a different "animal" in terms of  PTO  internal drive options. would have to be or else the dump pto speeds depend om main in gear. 2=i more then likely confused the issue with improper explanation of early style pto change over

this type of procedure it is better to scare someone in doubt of doing the job. WITH TOTAL RESPECT also. pull back on the shaft internal shimms may drop ::correct? it's been a while. should a rear mount P T O be removed and replaced with side mount is it necessary to turn counter shaft back to180 position for a flat recover to fit properly ???? I may be misreading with purpose to remove remote pump , and keep rear mount P T O with self contained pump?

may have confused things stating  "necessary to turn COUNTER SHAFT back 180 position"". not one of three main countershafts. sorry all.  possibly better title would be rea  auxiliary shaft? not sure of proper name description. 

lost when trans numbers used ::107/// TRD72 etc.

DON'T BACK OUT;   your info more correct based on newer units. my failing memory goes back to when things like rear PTO's were BRAND NEW items. I did a few  ;remember the warnings of pulling/turning small shaft near lower cover. NOT ONE OF THE THREE COUNTERSHAFTS  shaft stuck out 3/8th in with slot cut in it. rear cover held shaft in some what. tapered press fit in trans housing. rear pto housing wouldn't fit flat without turning shaft.  might have been used for oil return to trans after pto installed

the most important thing is to keep the project positive/ fun/ and within budget. the proper 100 score in judging for correctness is long down the road for most. $500.ooo floor mats don't seem all important when a roll of HD rubber material can be cut to cover till time allows for mats having Mack  embossed show up.

the side mount PTO uses a seperate gear, no timing required..  prying up on the lower countershaft keeps that shaft 'timed' while the work is being done..  the bearing cover for the lower shaft is the same as the upper (2) if you decide to not use the lower for a PTO drive..  

have designs changed ; if lower rear cover is reinstalled, doesn't the small external shaft near cover have to be turned back and freeze out plug or5/8bolt installed?? to install a rear mount pto after drain/remove cover/knockout center freeze out plug , install 5/8bolt and very gingerly pull back shaft ( 1 1/8 socket ?over shaft)+no more than 1/4 in or shims fall internally. open end/ adjustable wrench and turn shaft 180 degrees so a new pto will fit.

I am not sure why it has that old fashion low air warning that’s like really weird

the low air warning(wig-wag) is based on the fact this real working truck has no/ none of todays electronics/ computers to let driver aware air is low. standards back then meant when air was dropping:: "oh ,I can make another 50 miles before I run out. the wig-wag was final notice== Hey driver that's it stop now ::LOL

has something to do with the idea =they make the big bucks and the decisions :the workin folk always question that thought ;don't we.

They should have got a 35t lowboy as a backup we have a 50 ft and lowboy tractor. We don't have anything big anymore except a jd 290 

seems as  life goes on the phrase "should have " has become more regular conversation..  common sense still around  the should have statement wouldn't be necessary. I can understand a pintle hook on tractor to make use of parked equipment vs buying a new piece which wouldn't have full time use. i take it to be lowbed being used  second tractor could be used with a tag trailer.

Other than that damn Tachograph it look like you have a nice clean unit!!!!

bright side , he can always remove the tacho rehook to original speedo in dash.

spin- on filter on B-model!!  I'm thinking cartridge filter in canister : remove #4 aeroquipt line (9/16 wrench) then 3/4 ? wrench for housing top removal  to access paper fuel filter. 

notice the "wig/wag" hanging down  front of driver vision ?  one concern I would have is the steel double plate along the frame , possibly to reinforce frame to carry large tank. on east coast the salt sand will have it oxidized beyond believe. sleeper and 5th wheel will reveal the truth.

611 would be a T673. May or may not be a C. 615 would be the V8. 607 and 609 would have come with NA 6-cylinders. One was the 672 cu in and the other was the 707. Can’t remember which is which, but it’s in the brochures I attach earlier.  Hopefully he can find vin number and engine id number. 

reading these numbers, think I quoted ole #1 R model Mack wrong. not a R609T  it is a R607 T  =1001 with a 672 cu in. /twin stick duplex 10 speed.

Boy, is my face red....well, actually it is rust colored. I got a fatter screw driver and a rubber pad to protect the aluminum and --presto- it popped right out.  There are 3 small angle brackets that curve down ever so slightly and "pinch" the frame. One side is attached with 2 of the tank bolts (3 brackets), and the other side of the angle have the loosely attached 1/4 net and the other hole is un-used. The pinching parts were rusting against the rusting bracket.  You can barely see it in the 2 brackets D-Day posted..the top bracket shows the slight "J" shape ..not an expected "L".  I can sleep now  thankssss

positive side to those type of episodes is next time you will know just how to do it!

This is when they were new..

that back half picture of same truck in your profile??? that's a nice lookin rig. 

complete engine code shouldn't be same as truck vin; which would have been stamped in right front frame rail. surprised its on title.  BUT as DCW said " it's registered and you have a title that's the important part.

old tattle tell on the dash (sangagomo) speedo for you youngsters LOL! open the door and install a chart. looks like I haven't lost it completely (mentally). called it close with the RL700 part. best of luck with the restoration. at least you have a great starting point.

spacer block under 5th wheel for added height  yet only 38 rears. ??  hauled HD trailer maybe  with light rears. better chance to make some $$ in parts rather then whole truck ?? polish doesn't make money; that looks possibly had less care mechanically too. agree based on picture of a rough life. Macks are like ole Soldiers rough life but keep on going .

providing someone doesn't "cut corners" when buying the pintle hook. there are HD spring loaded hooks  for such applications. I would think twice before installing a simple "pick up " style.

Ya that was my thought too... I'm too young to know much of aluminum frames but seen it on a local wrecker recently and yea it was thick. What are pros and cons of aluminum frame?

be interesting to see specs on the wrecker!!  think it's unusual for a wrecker to have alum rails. wreckers have more twisting/ turning off road . another work of modern technology I guess. let's not go off topic now . just ole man thinking out loud.😱

Wonder why the nose seems extremely long???? 

western RL700. longer nose.. total suspense waiting for the last two digits of model number==RL785/ RL773 etc. hopefully model number matches engine.
