If the Mack part number is not helping you, just look for a ratio adapter with the type of drives you need. I assume that you need a 1 to 1 which should be easy to find. Try ebay, there are always some there. The same part can also be found on many old transmissions as well for speedometer drives. If you find used ones the ratio is usually stamped on the adapter housing. You will need either a square or round drive, and you'll need to know the size of the drive as well.

The truck is a Grabowsky. Max Grabowsky was one of the pioneers of truck building. His truck was later called the Rapid, a very good truck that sold well. Eventually his company was absorbed by William Durant and operations were consolidated with the Reliance truck company, with the new product named the General Motors Truck, or GMC.

Welcome! You have come to the right place for help. The first part in question is obviously a Pierce Governor, its purpose is to limit the maximum speed of the engine. The second part is a hydraulic brake booster, essentially a power assist. A was mentioned, the Mack Trucks Historical Museum can provide you with all types of information pertaining to your truck, by all means contact them. Do I guess right that you are in Poland? Can you tell us how this old Mack found its way to you? What part of the country are you in?

There were 365 model FP Macks built between 1940 and 1942. The Buda 6DT diesel was an option. You are correct on the cab being the same as an E model. I would say that is a pretty rare truck. It was definitely a factory model, but the third axle may have been added afterwards. It wouldn't me surprise me if someone wanted to give it a new home. More pictures would be great if you can get them.

Latona brought the green DM to our antique truck show in Harford PA maybe 15-20 years ago. Great truck. I think it won the slow race. Several years later I saw it with an I beam trailer parked in the Back Mountain or maybe Pittston PA area. At that time it looked like it had not moved in a while.

Brandon , who owns the truck, is no stranger to Brockways. I checked out the truck at the Brockway show this year and I was impressed with it. It is a nice survivor. Like he said, you could just drive it the way it is, or it would make a great project if you wanted to get more involved.

To answer your question James yes, modern brakes could be adapted to your truck. But it also could become an even bigger task than adding power steering. And again that is something you could do further down the road if you choose to. I would guess that since your Mack was originally a fire truck it probably has had a fairly easy life with few miles, and not many heavy loads. Your brake drums are probably fine. When in good operating order the original brake system will do everything you need it to do.

Happy Birthday. Your wife has good taste. That's a neat little truck. What are your plans for the it?

James if you are able to keep this discussion going, it will be a good motivational tool for you. You already have the attention of old Mack fans from at least two continents, and knowing that we will be waiting for updates from you should help you keep going on your project. Most old Macks like yours steer pretty well the way they were built. I don't believe that power steering was even an option. Of course you will make sure that all of the joints on your front end are free and well lubricated. With the relatively light 330 Continental engine, you may find that there is no need for power steering. Maybe you'll have to work a bit at low speeds or in tight spaces, but the original system will probably be very good going down the road. Of course PS can be added if and when you choose to. Probably your best bet would be the linkage type assist that attached between the front axle and the tie rod. That would allow you to keep your original steering box and avoid a lot of potential clearance issues. Adding power steering can be done, but you will have to be the designer, engineer, and fabricator, not to mention the test pilot.

I would recommend that you first decide what you want to do with the truck and how involved you want to get. Then formulate a plan. Do you just want to assemble the truck and make it drivable ? Or do you want to clean, sand blast, refurbish, and paint every part before reassembly? There is several years and many thousands of dollars difference in the two methods, not to mention the outcome. Since you are a young man and new to the old truck world, my suggestion is that you don't go the full restoration route, but rather just clean up the parts and put the truck back together, making whatever repairs are needed to make it drivable and safe. Your life is going to get very busy in the next few years, and you will get much more enjoyment out of an old truck you can drive compared to an in depth restoration you can't find time to work on. The truck can always be restored later, perhaps when you have more time and money, and by then you will have learned much more about your truck, too.

Of course I have no idea about your White, but we often forget that in the very early days of trucking the horse was still widely used. Many trucks were equipped with water tanks and used to "flush" the horse's manure off the streets in larger towns and cities. Good luck with your new Mack. It looks like you should be able to get it running without too much trouble.

Yes, Brocky, they are the guys in Illinois. I don't know about anyone doing Continental work in Utica.

It's nice to see another B model in good hands. Are you in PA ? I am finishing up a long term B model project of my own. I have accumulated a lot of extra parts that I no longer need.

Thanks for the pictures James. Finding an oil pump for the 330 Continental engine should not be a problem. That engine was not only used in a lot of trucks, but it had dozens of industrial and agricultural applications. They are very good engines, too. There is a place that might even have a new old stock oil pump, Home Page - Montes Equipment Here in the northeast there are still a fair amount of old Brockways with that engine to be found as well.

Welcome, James. I'll bet you father would be proud to know that you plan to finish the job he started. Pictures would be nice, but more important might be the model of your truck and its engine. Parts are out there, but sometimes you have to search to find them. This board is a great place to start. So tell us, did the truck run since your family has owned it? What engine does it have? I generally prefer to see classic trucks like yours kept original. But it's your decision, and a lot depends on what you plan to do with the truck when it is finished.
