The 5.9 Cummins is a nice little engine from 160 hp up. I've just gathered up everything needed to install one into a 51 Brockway, replacing the big flathead six gasser. It looks like it will be a pretty simple swap. I have for sale a running DT466 still in a truck, which I could not use, as it is too long to fit under the hood of the Brockway. The Dt 466 is 210 hp and up. both are very good engines, easy on fuel, and easy to get parts for. Steve

The Mack-Scania connection is pretty well known. Mack - Man might take some research . Right on Joe D. Steve

mike69 I sent you a pm. Steve

The company I work for is planning to scrap an ex Roadway Tractor. After some one asked about it in an earlier post, I got some more information. It is a 1979 U626ST. It came with a blown 6V92TT, which was repalced with a 300 plus. It has a ten speed and a single drive axle with a dead axle behind it, on a hendrickson walking beam. Guys that remember driving it say it ran and handlled very good. The truck has been used around the yard for a long time, and is set to be cut up for scrap. My boss told the junkman to put it to the side to see if anyone wants to save it. The cab is rough, but I am sure it will run and drive. It is near exit 211 off I-81 in northeast PA. Sorry, no pictures. I would guess that it could be bought for scrap price. Steve

The company I work for had one of these for many years. It was really ugly. The last I knew the 318 was installed into an old Michigan loader, and the rest of the truck was scrapped. They still have an old Roadway Mack, if it didn't get cut up yet. It has a 300+ Mack engine in it now, but I was told that it had a Detroit when built. It is a U model , but the hood is not as high as the truck in your picture. It does have a Hendrickson suspension with a dead axle.

The rotary injection pump in not a Roosa Master. It is a Bosch. Either a model PSJ or PSM. They are good pumps, with variations used on a lot of engines other than Mack, including many older International DT 466 truck engines.

Michael, I have had good luck finding odd parts on ebay. If you know the dimensions of the valves you need you may be able to do some cross referencing and find a match either on ebay or elsewhere. Are your valves different than a 673 ? the block is pretty much the same isn't it ? You could also change your valve seats to match the valves you have, if you ended up with a different seat angle on each head, you'd never know the difference. Good luck, Steve

I have a 673 that leaked air just about everywhere it could when I first got it, including the hand primer pump. It took a while to find and repair all the leaks. Stick with it , you'll find them. Steve

Hey Doug, Good looking truck. I don't remember seeing a Holmes 750 on a single axle before. Judging by the air cleaner is no longer has a 673 in it. What are the specs ? It reminds me of an orange fat cab GMC that has been to Macungie. Is there a connection there ? Steve

tniss, Going through the court in PA is not terribly expensive, but it is slow and there are many steps involved. To file the petition in your county court can vary among counties, but for me the cost was $ 72.00 a couple years ago. Then you need to get certified copies of vehicle records from PennDot, $10.00 +, A couple of notarized signatures $ 10.00+, certified mail you need to send $ 10.00+ There may be some other items, but you get the idea. And this is all before you get to court and the judge says you own it, and then you can apply to Penn DOT for a title $ 22.50 and next you"ll have the pleasure of paying your sales tax 6%. Another route to getting a title is to go through a title service. There are many of these to be found on the internet, and some of them will deal with trucks, though not too many. Basically you sell them your truck ( on paper ) and they title it in their state, and then sell it back to you with paperwork that will go right through Penn DOT. This is easier, but more expensive....if you find a good co. to work with. Best of luck to you, Steve

TNISS, Firemack has a good plan. If you can come up with an old owners card it might speed up the process. You may have difficulty without something like an owners card or a title number, if the vehicle was titled long enough ago that it doesn't show up in the PennDOT computer system. If that turns out to be the case, your best bet might be to go through the court to get a title. I have done this successfully several times, and while it is a pain in the neck, it does work. Good luck, Steve

Thanks Rob and Glenn. Steve

I am " restoring " a B 61S. I finally got the engine back in the frame, and next is the Quadruplex trans. The truck had no transmission in it when I got it. I remember hearing that it's best to leave one of the trans mounts off to get it in place. All 4 of my transmission mounts are off now. I need some advise - which mounts do I put on, and which one (s) to leave off ? Thanks. Steve

There is a thermostat on ebay now, 3-19-10, search vintage Mack. I paid $30.00 at the local dealer for mine.

The patent numbers are not the VIN numbers. Patent numbers are virtually useless. Most vehicles before the 1970's were identified by serial numbers. B66 gives you the best info on where to find them.

Yes, the frame will handle a diesel engine. The obvious choice would be a Mack, and if you had another B model donor truck, the job would be fairly easy. Otherwise you are limited only buy the tape measure, your skills, and your wallet. A lot would depend on what you plan to do with the truck, and what you want it to do for you. Will it be a play toy, or work for a living ? Do you want big power, or economy ?

Penn, Mack built their first bus in 1900, but did not build any trucks until 1905. What do you have ?

I have not seen it, but I have been told of a 4X4 B model built the way you describe in Mass. It has a duplex trans, and army truck axles. The truck was used to spread fertilizer in fields. The typical Mack has straight air brakes, not hydraulic. The Mack PTO is generally driven off the main box ( 5 speed ) but can be driven off the compound if the case was machined that way. You probably have a PTO access on the transfer case, too. Go for it.

Terry, If you go to the "wanted" section of this site there is a current thread where someone is looking for an ED model ( slightly lighter than the EF ). One is offered for $40,000. I really don't know the value on the open market, but your EF looks very good and should bring a high dollar. I have some old photos of a wrecker like the EF that was for sale back in the sixties. I was just a kid but I wanted to buy it, but I was shot down by my parents. Steve

Your site looks very good, Josh. We all like pictures, so keep them coming. Does the B 53 have integral power steering ? Most B 53's that I've seen do, which is a real nice thing to have. Keep up the good work. Steve

Daniel, You have a 34,000 lb bogie. Steve

I have a friend who owns an MB which came from the factory with a 413 Chrysler. It has since been replaced with a 360

Joe, Your H63 is a great looking truck. Of course it is your choice to do with it whatever you want, but for what it's worth ,I think it would look odd with Budd wheels on it. The only way I can imagine aluminum wheels looking right on such a classic model would be old style 5 hole wheels on the front axle only. Steve

Jim, Look in the photo gallery. Check out" Mack trucks from Haukes Kekerdom the Netherlands" by Pieter78. There are some good pics of N models there.
