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.

I have not yet sent any info to Mack museum. I haven’t searched to hard but wasn’t able to easily find the vin number on the frame. It’s definitely on the list of things to do. I’m working on getting a the back story of the truck also. I’m not 100% sure but I think I’m only the third owner.

This is the shift plate. I believe the transmission is a TRD(L) 722(0) it has two sticks and a third one to engage the pto in forward or reverse. I’ll look for some engine numbers this weekend but in another thread I asked about the vin number because on the title the vin number says ENDT673C. According to what I’ve been told is that they didn’t really do the vin thing back in 69 and using the engine code was something they did. 

in '69 the  truck vin number didn't spec the engine totally. ENDT673C shouldn't have been part of a vin. may have been on a bill of sale/ title; don't remember eng model on truck vin. the engine would determine the model number on registration such as a R-685==maxi  or R611==thermodyne.  in the picture posted not seeing a turbo. looks Natural aspirated. why does vin say ENDT673C?

correction  better look see a turbo . sorry long day changing air bags outside on a kw. with two tall shots of Polish brandy after.

why ??? oil bath to dry??

[mowerman]

No the conversion kit for the spin on I’m not going to bother with it

[mowerman]

Oh, sorry about that. I worded that wrong. I was talking about the oil filter. I guess I shouldn’t have said oil bath I am frustrated. I just blew out a tire 60 miles out drive tire recap they just put them on about three weeks ago.

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.

Somewhere on here there is a definitive list of all the various model numbers and the associated engines. It was put together by some of the old timers who had lots more info. I’ll try to find sometime and put the link here. It’s on here but it’s hard to find from the phone. Easier on my computer!

[doubleclutchinweasel]

Here’s a good start.

So the engine is definitely an endt673c it has a turbo but no cooler. On the title the vin number is the engine code although that is not the actual vin number. I just retitled the truck in my name and they did not even question it. I was told that back then they didn’t care to much about vin numbers and would put engine codes instead of the actual vin. I even have the original purchase paperwork and the engine number is also listed as the vin. Doesn’t make sense why they would do that but it is what it is. I’ll post some pics of the engine and the number tomorrow.

I just got done replacing all 6 air bags, all 6 shocks all slack adjusters and s cams on a low boy trailer. It was a long project. Things either wouldn’t come apart or wouldn’t go back together. But I finally won lol

As long as you got it titled, all is well. I liked the C a great deal. It had the extra head studs like the 237, IIRC. 
 

Keep us informed…with pictures!

[mechohaulic]

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.

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.
