17 digit vins started in 1980. Before that it was model and engine numbers followed by the sequential number the truck was built starting at 1000 ? I think ? Theres threads on vin numbers. I will try to find one and post. Your vin should be where Jojo said. Right frame rail behind steer tire. Should also have a plate inside the drivers door.

Cool truck and video. I never had much to do with a Transtar , but I have a lot of miles on its little brother the Loadstar .

67RMODEL described the 2 stick better than I could . They are a great trans. I agree with him . The 85 R looks the most interesting. Like he said , as long as the frame is ok.

Congratulations on your retirement !! I agree with you 100% on the generation of waste. Nothing is designed to last. Nothing at all. LOL, don't worry about your rambling , after 50 years of changes to the industry , your entitled to vent . Im able to keep my old R models running nicely but I probably couldn't even change a headlight in a new truck .

LOL, that save the world Technology , I can handle . Todays Technology ............ no thanks . I will run my old reliable stuff till I retire or the government makes me park it.

Welcome

Your right Jojo, the relay has no air to it when the parking brakes are applied. When the brakes are released (yellow button in ) it sends air to the relay valve. Thats why its important to chalk the tires and release the brakes when you get a smoke test done . I'm sure you know this , but could be very handy info for someone that's new to older Macks. I love the Superliner dump you posted. Looks too good to use . Thanks again for the pics Pic of the small hole that's on the bottom of the reversing relay

That looks amazing ! I like the colours of the superliner. I wish you lived closer, I have an E6 that could use your professional touch. Thanks very much for the pics !!

Sounds like a cool project. If the owner is ok with it ? maybe you could share some of the progress.

I'm sure you know this already Vlad, but if your experimenting with older relay valves. They are designed to leak a small amount of air, out a weep hole on the bottom side of it. I found this out the hard way. Buying a new one to leak the same as the old one did. lol The pic below is out of an R model owners manual.

I agree 100 %. Its the guy that says he knows it all is the one you have to watch out for 😀

In a thread a while back you asked about the reversing relay in a superliner you were working on. Rather than sidetrack that thread I wanted to try to help. You may have already sorted what you need . If you did, no problem , this may help others . I want to start by saying I'm no expert and most on here know way more than I will ever know. Any info I know came from BMT. It's great. I have found through trial and error that the relay valve changes the trucks performance a lot . There has been a lot of threads about them in the past . This one is useful , https://www.bigmacktrucks.com/topic/47110-puff-limiter/#comment-347471 Theres different relays for different motors . They all have a part # that ends with a number followed by an "X" like "5X" . That number is stamped on the end of the relay valve. The smaller the number the higher the rpm before it fuels . That's to keep the smoke to a minimum . A 5x or 6x will fuel at a lower rpm similar to a good ole 237. I think 237 came with a 5x from factory , but not 100% sure.They go as high as "10x" I think? The 350 your working on would have a 3x I think ? There is a "CX" too. I have tried it on every truck and decided the best spot for it is on the shelf. Truck has to be at 1700 or so before it kicks in. I put a 6 x on my 350 4V . It worked really good but smoked more than I liked. I didn't want any trouble from the smoke police, lol . So my solution was an electric solenoid in the supply line to the relay. I run a 3x. My truck works great and I'm not afraid of a cop behind me, and when I want to have fun or some bottom end power, I flick a switch on the dash. I love it. A lot of the guys used air valves to do the same thing. Remember that the relay is only half of it. The number of shims in the rack limiting cylinder on the pump is very important to. Theres info on that in the link provided. Heres a pic . You can see the new blue line to the relay. It should really be black so it doesn't stand out but that's all I had the day I did it , lol . Hope it helps a little .

Thanks so much for sharing your fix. So many times people ask for advice and never come back to say what the problem actually was. We are very fortunate to have some very knowledgeable folks on here willing to help. Would it be possible to see your RW We love pics

Jeff, if you haven't checked the piston under the the brake pedal like Jojo mentioned , make sure you take it apart and clean it before you start buying parts. It can just stick on a little and you would never know and seem like its ok. And I think it was said , but check the hand brake( trolly valve ) is not on. I have chased that before. Looking for why brake lights on and hand brake had been applied without me realizing .

Maybe double check the back is grounded .

I checked PAI website for you. It list the part but says "out of stock". I then checked for a bunch of other parts and everything was out of stock. Even newer Freightliner parts. I'm wondering if something is wrong with the website ? If you haven't called and spoke with someone , might be worth a try ? A few years ago I got a turbo crossover pipe for my 237 very easily. I would think ? that would be harder to get than what your looking for. And if it turns out there is no more e6 engine parts , a lot of us are in trouble Wish you good luck with your search

If you run in cold weather , follow this advice or you will be froze up on the side of the road . About the size of JIC ..... I don't know what # it is , all I know is my stuff takes a 1 inch wrench like jojo said .

Welcome

I love seeing our 4 legged friends . Here is one of mine 😀 Its not very clear , but you get the idea , lol . If he's in the house and hears one of the trucks start up , he whines until I get him and take him for a ride . IMG_1899.mov

Welcome Aboard Congrats on your new Granite , It looks good ! You came to the right spot , there's lots of knowledge here ( unfortunately, not me ). I found it interesting you say there is a 2 to 3 month wait for a dump box . Up in my part of the world (Ontario ,Canada ) there is an even longer wait for a box, and I was told prices went way up . I'm not sure why the demand ? Just find it interesting .

Congrats on the new to you Superliner. It looks like its in good hands and going to live again . The Maxidyne emblem is interesting on your Econodyne . I find it interesting because we have discussed on BMT some trucks having Maxidyne engines with Econodyne emblems . Treat your Maxidyne emblem like gold. The can not be found . About your pump , I'm sure you know this , but on the very slim chance you didn't . There is external return spring . If this is off , the throttle will run up itself . Very fast . lol . Don't ask me how I know this

Welcome aboard , Thats a good looking B. I'm sure it will bring you lots of enjoyment . Have fun with it !!

Thanks for explaining the difference between the CM and the CS . Now that I know the CM is Macungie built with CH / R parts , I want one . lol Like all your stuff , the CM looks really good .

Hope it works . Please let us know how you make out .

Before you buy anything or tear everything apart , take the supply line off the control valve and put some air tool oil in it . Then turn wipers on and off a lot , keep putting them in park , if truck has been sitting for a while , might be enough to solve your problem . In case you didn't know , park position is important . If your wiper control is pull out and turn to the right to increase speed , the park is... push in all the way till wipers go back to the bottom . If you turn the wiper control to the right to turn it on and increase speed , turn to the left all the way till wipers go back to the bottom . When they are in park, no air should go to the motor and therefore no air leaking out the exhaust . Just my thought anyway
