I just came across the receipt for the clutch I put in my B some years ago. The truck has a 673P and TRQ7220. The replacement part is identified as UQ M4106-15200VBS, reman clutch. It came from a Mack dealer, but I' not sure if it was a Mack part. I also looked up my Mack build sheet, and here are some numbers for the CL28 Clutch : assembly 101HBA 4116D, Clutch Disc Assy 101HBA 3144B-P9, clutch pressure plate 597HBA 416B Good luck!

According to my information your 128 is a 1960 and your 148 is a 1957. If you want to get the original build records, contact the Mack Trucks Historical Museum. Give them your serial numbers and a donation, and they will send you whatever they have on your trucks. It looks like you are pretty serious about the 148. Are you planning to keep the flathead 6 for power? My guess is that as an oil truck it was probably built with a straight 5 speed and a slow rear axle. I have an older 148 myself, and the 427 flathead is an excellent engine, but it doesn't like hills at all. It has an overdrive transmission and a 2 speed rear, which make it fun to drive, but it is still geared for about 52 mph.

It's always good the hear of another Brockway that has a chance at a new life. There is a very strong following for Brockways, and you will find a lot of helpful people once you get in touch with them. That FB place is where a lot of them hang out. You should plan right now to be in Homer NY the second Saturday in August for the 25th anniversary Brockway truck show. This event should be on every old truck fan's bucket list even if they don't own a Brockway. And if you do have a Brockway, there is no better place to be on that day. If you'd care to share your serial number, we can probably nail down the year of your truck. It looks like it has potential. There is a lot of interchangeability between the different models. many parts from an 88, 146, 147, and 148 among others will fit your truck. Even your fuel tanks are the same used on some larger models. Any more pictures?

There were two different ten speed transmissions available in the H63, the TR -67 series, and the TR-72 series. The 67 series would have two shift towers, the 72 series would have one shift tower, and a shaft that the other shifter pivots on.

What transmission do you have, or want? I have a triplex that would fit, but you have to have the right shift levers to make it work.

Sorry I can't give you the settings for your pump. Older Mack "Operation and Maintenance Manuals" have the governor and rack setting dimensions in them, but at some point Mack decided that they would stop giving that information out to just anyone who bought a truck. My literature shows a 313-GC-4132 and 4133, as used on a 673P engine. Your 711 is a little newer I suppose. That P8 at the end of your part number is the one to give you the rack extension spec that you want. If you don't have any luck here, I bet the Mack Museum folks could look up the numbers you need. Steve

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.
