I have some old Brockway gas jobs with Fuller overdrive transmissions that use that same 5 speed pattern. It's a long way from 1st to 2nd. As for your other lever, I recall hearing old-timers refer to it as the "mud stick". It is a real lo hole that is really only meant for something like  on/off road dump truck use. It was ok with a gas engine, and it might work well with your Cummins, but that transmission was never meant to be used with a Mack Thermodyne diesel. It just doesn't have the gear splits you'd need to stay in the narrow power band. 

The short answer is no. But your 510 undoubtedly has a standard SAE flywheel housing. Do a google search for SAE sizes and measure yours. You probably won't have any trouble finding another transmission to bolt up, but the throw out bearing /collar might give you a bit of a challenge.

Since you had the air cleaner off with the truck out in the weather, you might have something other than a hydraulic lock. It is possible that some critter found your air intake to be a good place to stash seeds or nuts or something like that. As your truck sat idling it sucked them in and compressed them as much as it could until it killed the engine. I actually had a similar problem with a Thermodyne once. I would suggest that you pull the valve covers and check to see if your valves move freely (the ones that should be free). I found thin pancakes of cherry pits on top of the pistons in my engine, just enough to keep it from turning. Strange, but true. Good luck.

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. 

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?

We also have a 1919 White model 45 five ton rescued from the scrapper. It was used as a water truck in Seattle, Wash.  No idea why a water truck would ever be needed in soggy Seattle.

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.
