Oh. Shoulda known.. Thought you meant mack script. Sorry.

Good one. I meant a parts diagram - you guys are so literal. FWD - you need to make peace w/ the Detroits.

Thanks for the fast response! Interesting. Seems to run great and virtually no leaks so OK for now. Anyone have an exploded view?

Found it. Thanks theakerstwo - it was there, block has very little oil or grease, but a coating of fine dirt (I'll wash it this spring). Didnt see the numbers but rubbed with a rag and there they were Again, without knowing where to look probably wouldnt have found til I washed it - thanks again. 10282054 Location for anyone else looking - front left, below accy mount.

Thanks for the fast and knowledgable responses. I will take another look in the next few days for the ser. number.

Casting seems to read: OWC-2. USA

With the snow FINALLY melting, like many I was out starting her up and poking around under the hood. I have never found an ID on this engine, can't find a plate near the inj pump, rocker covers or ? I don't even know much about it (I've been around mostly Macks with pedigree drivetrains or Scania's in the 400's). The guy who put it in the truck said it was a motor used in off-road equipment. If I remember it correctly most Cummins I've seen were light green. Any info?

A twin stick and a V-8 in an R model,..I wouldn't worry about the grass being greener anywhere else! Awesome set-up. As for the air steering - keeping your thumb out of the wheel is no joke. Rolling off a rock or a curb, or onto one, and you'd never believe that wheel can spin so fast! Thirty years ago and my thumb still doesn't bend all the way. It is fine most of the time, but if you do a lot of backing with slow steering and braking you may need to hold the maxi off. Look forward to the pictures.

What emblem do you need?

Did you try General Ike? I am about an hour away but won't be free for a few weekends. It has been on Craig's for months. Says it hasn't run in three years.

Where to start? B-75, 73, and 615's have the classic look of B models with the great looking Sr. radiator - congrats and now that you have it hope you hold onto it , but same with a V-8 R model! That wrecker is cool -cabovers getting hard to find and look nice with wreckers, flat beds, etc. What kind of shed are you planning? I've been wondering the best way to go for a two truck shed? .. Pole barn, pre-fab?,

Welcome! How's the search going? An F is a good choice, cool looking and getting more rare. Some nice ones in the gallery. You will find guys in the hobby are very helpful and active on the site. Good luck!

Very cool. Always surprised by twin sticks in a cabover, drove split rears but would seem tight w the engine there. Cabover s are getting so rare, Mack's even more so. Looks awesome.

Amazing progress. Can't wait to see the cab cleaned up. Funny how rough paint can look and the metal is so solid underneath.

I met this guy at the ATCA show in Montgomery NY this year. He said it wouldn't start that morning so he was there in his old pick up. Wayne Otis would know how to get ahold of him. When I see him again I will get some info and pics. Sorry FWD I'm a lifetime Mack guy but a Detroit is a Detroit. An R with a Detroit 12 is the best of sights and sounds in one. Sorry again.

This was a brutal winter so don't feel too bad. For next year the trick is turning over fast and fuel not jelling. Use a battery maintainer or trickle charger (they even make solar now for long distance from an outlet) and put some fuel additive in in the fall. They do make tank heaters, but haven't used them. A good block heater (check yours) or dipstick heater also helps the engine turn faster - thin oil. Starting fluid once it's turning fast enough should get it going. Mack put ether systems on so they won't hurt it as long as you do it once and don't try to run it on just starting fluid (you don't want to try to spray more once it starts or spray during extended cranking). Spray it good,sit a few seconds, start it. As for the salamander and torpedo heaters they work in an enclosed space but used too close I've seen damaged wires and rubber not to mention paint, etc. if you need to run and go in all weather you'll need a garage or to start it every few hours in sub zero. Big diesels are hard in winter, why the New England fire companies went to gas ten to twenty years after commercial truckers Good luck.

Very nice R model ..Love the air intakes..

Great story! Congratulations and good luck. They are remarkedly well made even when they've sat. I hope you can get it running soon and without too much trouble. It's an awsome looking truck - would look great rolling down the road in those colors!! Awesome.

That shovel on the trailer probably beats all the logging trucks and Hoover Sam trucks I've seen in pictures!! Imagine being the one to say "hey, I've got an idea... Let's pull a shovel with it.." These guys were real innovators.

First, I own a chain drive (started it ALL, the DNA of Mack) and a B model (awesome styling, indestructible - they are timeless classics), but the R model and its sibling the RD (a heavier duty version) were probably the greatest all-around Macks of all time. Think about it - why do they still look great almost fifty years later and why did the production run go forty years straight??! A modern-day classic. Anyway, that's my two cents.. Some twin sticks are a five and a four, some a five and a three, some a five and a two speed. I learned on a 69 R model with a ten speed, reverse had a high and a low, and you could just shift through the five speeds straight, and use the aux. stick like a high and low. To do it right, I started in 1-low, and shifted every half gear -1 to 10 in about a tenth of a mile, from zero to 20 in about six seconds, quick double clutch or no clutch at all. Don't worry,drive it a few days and you'll be right at home. Like I said the other day, every one of us was green once. As for the R or RD, look for a nice one, and you'll be happy in the long run. They are easy to work on, parts are everywhere, and many are affordable (example, new Mack windshield for an R is $125). And... before the other guys say it, "post pictures" when you get it.

Congratulations and thank you for 42 years of service to the community, didn't make you rich back then. I grew up right next door in Greenwich and remember Port Chester in then as pretty hectic. Things have probably changed in many ways for the better, but seems there are not as many friendly faces as in those days (people come and go more, less neighborhood feel). Remember Miller's Autocar wrecker on the traffic circle on the Post Road?, funny, seemed like a monster in those days! I hope you enjoy your retirement, more time to work on the Mack's! Take care and happy New Year in retirement.

I'm no where near the expert 41Chevy is, but people do discuss changing the drive sprockets for a higher top speed (the drive sprockets are easy to get at and sprockets on the wheels are about 24 inches, so no much you can do there). There is a story of a guy who changed sprockets plus some other mods to get highway speeds from a chain drive (a hair raising thought!).. Link below, nice looking truck either way. http://forums.aths.org/43526/Chain-Drive-Macks

41Chevy. Thanks for the brochure pics, they definitely made a lot of improvements over the run. My shifter is primitive compared to the pics you sent, and no vacuum or front brakes. Mine was a crane too - found this old picture of it on line, but the crane was scrapped. I guess you drove slowly and down shifted often - no to mention steering! Sorry, look closely it was behind a spring shop for years.
