Wouldn't the three filters be an "ESI" option?  Std is 2 filters?

What is an esi option?

You are way ahead of the game in that the filters have already been set us as spin-on.  That is much easier to work on.  You've really got a nice starting point there.

Yea for sure! I would rather change spin ons than cartridges.

Does anyone know where I could find a latch like this one picture? I’m missing one off or one of my battery boxes and I would like to keep things as they came.

NO  that circled item is OIL COOLER.  you do NOT have the canister filter.. the three white spin-ons will be your oil filters. great job on the   round one clean up.with the eviction of raccoons ; strong suggestion would be to spray fuel/ brake pedals  making it easier for future operation. check roller under brake pedal and plunger . raccoon pee can rust out a lot of parts that should move

Thanks for the clarification on the filters. I knew the 3 spin ons were oil filters but I wasn’t sure if there was something I didn’t know about. 

Now that we got the interior cleaned up the next step is to start fixing all the little things. There are quite a few things that don’t work quite like they need to. Then move onto the bigger things.

And, again, I am jealous!  Looking great!  And raccoon free!

I see there that you DO have the "C" version of the engine.  I have always liked that engine.  Pretty sure someone had to spec that as an option, because I think the "C" was not standard equipment.  But, I could be wrong.

Your truck may have the big canister type oil filter on the left side of the engine.  That oil filter cartridge is still available (I got some from CarQuest), as is the diamond cross-section "O-Ring" that seals the 2-piece canister.  That is a WGB Oil Clarifier duplex oil filter, with a "full flow" and a "bypass" section in the same filter.  Mack number is 236GB311A, IIRC, which might cross over to a Wix 51233.  Seal might be Wix 15114.  But, I am not sure.  The correct seal has a diamond shape, not a round shape.

Those are good filters, but the check valves can start to leak down, which can drail the filter into the pan and make the oil level look high.

There should be a number stamped on the driver's side of the transmission (see below).  But, it can be pretty hard to see.  Pretty sure you will have the TRD-722, based on what you have already shown us.  If it is the "L" version, it should have an aluminum main case, which would be pretty easy to check with a magnet.

 

Thanks! I’m pretty stoked that this thing is mine. It sat for awhile before I got the title and then got busy with life and then winter. So now that it is all over and I get to actually do stuff to it, I’m just still in shock about it. I’ve always wanted an old truck and to find one like this is just really a dream come true, and on top of that one of my three sons is actually just as excited about it as I am and loves to come help out and tinker with it. He is really hoping we can take it to some car shows this summer.

The transmission has quite a bit of build up on it. I cleaned some of it off and found some numbers but judging by your pic I wasn’t quite in the right spot. So thanks for the reference, I’ll keep looking. 

Below is a pic of the engine. Are you talking about the spot I circled? Is that a filter in there?

It looks a lot better.  I dont envy you cleaning out that mess.

Thanks! Yea it wasn’t fun but it needed to be done. Now I can move onto better things.

Before I cleaned up the floor. 

Today I had a couple of goals to work on. 1) get the chassis/vin number, engine number and transmission info. 2)send the needed info to the Mack museum 3)clean up the interior 4) lube up the doors so they actually open and close. 

So the only thing I didn’t get done was finding the appropriate info to identify the transmission. I just ran out of time so I’ll have to cross that bridge later. But I did get the other info which is in the pics and you can also see in  the pics that the interior needs a few things. Surprisingly the floor is a lot more solid than it looks. When I originally found this truck it had two dead raccoons in it cause the window was cracked enough for them to get in. Today while cleaning the interior I found what was left of a third raccoon and baby raccoon remnants. 

Ok boys so here is the thread that will contain all future info and progress for my truck unless I have an actual question then I will ask those in the appropriate place.

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!

I’ve seen it on here  before but I couldn’t tell you where.

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

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

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?

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.

Look right in here...

Thanks! I’ll check there this weekend. Finding that number is on my to do list this weekend along with cleaning up the interior of the cab.

Happy birthday!!

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.

are you trying to make me feel old??LOL .I drove those in the brochure  when they were brand new. LMAO🤣.

If you really wanna feel old, my mom was 8 in 1969 when my Mack was built. Lol I wasn’t even thought of yet.

My god I would love to have that truck in the brochure photo brand spanking new as we know most of us wind up with them after they have been beat to death and need everything lol Bob

It would have been really cool to see my truck when it was brand new.

The transmission may actually be just a 722 and not a 722(0).

Sounds like a Duplex.  2 sticks?  Got picture of shift plate?  Could be 9-speed (overdrive) or 10-speed (direct).  Very common behind a 673T.  On the gearcase at the front of the engine, you should see numbers like "T673" or some variation (see below).  Those numbers can help identify the specific variant of the engine.  This one says "T673C", indicating the 250HP version, the ENDT-673C.  Also, there could be a tag on the engine that shows the actual HP rating.  On the pump, maybe?  Can't remember.

R611T...The "611" indicates that it came with a ENDT-673 Thermodyne of some version.  The "T", if you didn't already know, indicates that it was a single-screw Tractor.  "ST" would have been the tandem-axle version.

We need more pictures!  We love pictures!

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.

Yes Same here … most of us are in the same boat lol… job alone 55 or so hrs a week and that’s without any issues Bob

Well luckily for me I dont get stuck at work passed 6 very often but we always have lots of work to do.

Yes, there’s always something ahead of it. I just barely started to mess with mine past couple of weeks…. Bob

Yea I have 3 boys that all wrestle year round and during the summer they add boxing and Muay Thai into the mix. So between them, work and trying to get things done for my wife time runs short.
