I don't know much about the numbering system for VIN's . The only thing I can add is that I have 3 Oakville built trucks that start with 2M2 , and I know they were not gliders because I've known 2 of them since new , and have there original build sheets.   

I do know that the 10th digit ( a letter , should be a "J"  in Vladislav's 1988 )  represents the year. 

Its a factory option.   A Grated clutch pedal .  You can see it listed as # 32 on my build sheet .

Something else I wanted to add, that I learnt today. I thought it was interesting.

 All you firefighters will know.

The button for ringing the bell ,if your riding on the back.   I realize they don't do that anymore . 

I'm not sure if this is the same trans.  This is a TRDXL 10780.  Hopefully Mr. Hancock can shed some light.  

I never got chance to say " NICE TRUCK " !!!!!   That dog found it's way to a good home. 

Theres a lot of info on here about puff limiters. The thread that helped me the most is this…...

Swishy posted some shop manual pics in the very last post. They are very helpful.   Thanks Swishy !!

Another point that may be helpful , is in the pic that Jim posted you can see on the bottom there is a CP5X   . You will find a they are all stamped with a number that ends with X.

could be a 3X all the way to 9X (i think)  The lower the # the less smoke you get. I have a 3X on my 350 and a 5X on my 237 .  

The relay valve is just part of it though. The rack limiting cylinder (where the line is going to from the relay) has to be set and working properly. The info Swishy posted shows how to test .  

I'm sure, going by everything else you've done , it will be whipped into shape in no time.   

Hopefully everything goes smooth with your new endeavour. 

Congratulations on your new truck .   I love this story because you were actually able to buy the truck . Stories like this usually end with the " the owner won't sell it , because they want to save it "or they think its worth $ 30,000…….    usually 5 years later it is sitting in the same spot , just a lot rustier .  

Thanks for including us in your endeavour . Hopefully you will include us in the work you do to it .  Nice truck 

Nice job !   I can see you only have one way to do things………………….The RIGHT way !

Tach cable goes to the front , right  side.  

I just got one for my R688st   part #  54MT313BP94 . I believe ? but not sure, the last numbers of the part # is the length of the cable.  Cables range from 80 to 218 inches , I think ?   

You can get them from Mack . I don't really have a user friendly Mack dealer, so mine came from PAI , it was only around 25 bucks .

Hey thanks. The rocker switch is only 2 position and might be the wrong one. Does anyone know if it has 3 position as heat max ac and ac

Yes it should have 3 positions . Just like ekennedy21 said, the vent should open on heat and a/c but should be closed for max a/c 

It doesn't get any better than that !  Nice job.   Thanks for sharing .

Looks great !    I like the exhaust tips.  And very impressed with paint.

I have used chassis saver. It goes on very nice ,and looks good when its new. Its very durable and doesn't need primer. But like POR 15 ( like Willie dog just posted about ) it also goes flat and chalky.

I'm doing  the frame on a different truck this spring and will just use rustoleum . 

Very  good job.   I love the colour.

Looks like a great save !   Thanks for sharing .   

You could check the quick release valves.  That is normally where the air is exhausted from.

Nothing.  This supposedly came from a fire truck if that matters?  The feed for air compressor is on bottom of water pump.  No other holes like on my old motor.  This having an oil cooler makes it slightly different set up.  Just curious if anyone has an r model with 237 to see where they route the hoses.

I can take some pics for you later today Larry.  I don't remember a line coming off the water pump. But not sure.

I love that !     Thanks for sharing.

Very good find !   Looks like it was a very sharp truck in its day,hopefully you can bring it back to its former glory.  I really like the fenders to. 

I don't take  change well. But I signed in , and in big letters it says Hello 85snowdog ……and it was beside the older non  symmetric  bulldog. I love it !!!   Good job Barry
