I had a B61 with the engine tilted to the ditch side. It was not the original engine . I have no idea why someone did that, but it was a pain in the neck to work on at times. In order to pull the back cylinder head, I had to drill a hole in the firewall to remove the last push rod. Trying to use a torque wrench at that odd angle from underneath was awkward to say the least. The engine must have come originally in an MB or some other cab over, as the engine number is on the back of the block, under the cylinder head. I took the engine out, changed the flywheel housing and water pump housing, and put it in a different B61 standing straight up. I like it much better this way.

Julie, thank you for telling us about your father. I have been following his posts here for years. He always added something of value to the conversation, and there was no doubt that he knew what he was talking about. He spoke with an authority that only time and experience can give. I am thankful that folks like your father take the time to share their knowledge with the rest of us. We will miss him around here.

Here are a couple pictures to help clarify things. The red truck has what some call the winter/summer air cleaner. it is the one with the cable on the dash . I think it was more or less standard equipment in colder climates, but that is only my opinion. The green truck has a Donaldson air cleaner. I have usually seen these on trucks with turbos, or Cummins engines, although I would bet you could have ordered one on any B model. The Donaldson has a larger capacity . The bolt pattern on the cab is the same and either one will bolt up. The Donaldson has some different brackets inside the cab, and the air tube that goes though the cab to the firewall is different , too. The tube through the cab is some type of fiberglass or plastic. The air cleaner from the red truck is available. Steve

I have a winter/summer type air cleaner set up if you could use it. It does not have the separate bracket.

It is more likely that your timing is retarded than too far advanced. When the spark occurs late, fuel can still be burning as it makes its way out the exhaust. Maybe you could set your timimg with a vacuum guage. Or do it by ear. Just advance the timing as far as you can without getting spark knock under load. The timing marks don't seem to be helping any. I doubt that the carburetor is the problem unless it is the wrong one for your engine. Pulling out the choke to make it run cooler is strange. Drilling your jets is not a normal repair for anything. The alcohol/water injection is a good idea, and will allow you to advance your timing more, but you really shouldn't need to add it. Another thought is that your cam timing could be off. Good luck

I installed a Garwood winch, the same model as Swishy's, on my B61. My transmission is a Quadruplex and I used a PTO with forward and reverse to drive the winch. An extra gear was needed to reach in to the pto drive gear in the transmission. The pto drives two # 80 chains to the winch. It could have been a fairly easy job, but I got carried away and made the whole thing more complicated than it needed to be. One of the things I didn't like was that the pto shifter, if mounted straight up through the floor, would have been right where a passenger's leg would be. I spent quite a few evenings making linkages to move that pto shifter over next to the 5-speed stick. I have not yet run the truck; it is still a work in progress. Steve

Truck has been sold. Thanks for looking.

DC Weasel, I have a 1966 B61 that was built with a 673C engine. It has a rotary injection pump and a pressed steel intake manifold. There are many differences in this late production B model compared to earlier B's I have noticed.

The Quadruplex weighs 815 pounds.

Anthracite Auto Parts in Scranton PA has an L model with the 510 for sale. It is a straight truck with a long wheelbase and an oil tanker body. Pretty complete and worth saving.

Thank you MrsMackPaul. It's very nice of you to recognize our nation's birthday from the other side of the world ! Steve

It looks like you found a nice old Mack. Hope you have fun with it. Attached is a picture of a 1949 EQT that I took this weekend at the ATCA show in Macungie. It was originally a tractor and might be one again in the future.

It would help to know what type of suspension your truck has, and what kind of road surface you were driving on. An unloaded Hendrickson walking beam on a concrete road will give the ride you describe. It's hard to imagine that tires with flat spots would perform any better at a higher speed. Good luck.

Nice find. It appears to be a knock off, not a real Mack bulldog. Cheap reproductions used to be fairly popular. Remember the ones with eyes that lit up?

Brian is correct. I would add that if your truck still has the 12/24-volt system and you are going to buy batteries, you can use 2 -12 volt batteries instead of the 4- 6 volts.

Your truck is coming together really nicely. I especially like your idea of the zippers on the shifter boot. If you don't mind, I'd like to borrow that design for my H63. It would be a big improvement over the rubber floor mat I have over that hot and noisy hole now.

Just to keep the facts straight: Brockway became a division of Mack Trucks in 1956. Brockway went out of business in 1977.

You can guess, or you can pay someone to figure it out, but there is a great source of information regarding speedometer ratio adapters not far away: Tom has done a great job of explaining the math for those who want to tackle it. I have just figured out what adapter I need to make the speedometer right after a rear axle change, thanks to Tom.

You're doing a great job, truck looks excellent. Would you be willing to share the part numbers for the cab jack repair parts? My H 63 jack is bad, and I haven't been able to identify it. You might have noticed in the Mack owners manual that it states that the cab should be supported by something other than the hydraulic system when working under it. I usually stick a 4x4 underneath for that purpose. It fits nicely into a small slightly dented area under the cab, where I guess others before me did the same thing. It would be a shame to scratch up your nice new paint that way, but maybe you could come up with a better idea.

Thanks for taking us along on your trip Vlad. Enjoyed you pictures and story. Nice truck. Cruiseliners are not seen too often in my area of Pennsylvania. Yours looks to have a very nice floor. hopefully the rest of the cab is good and solid. I especially like the picture of the Pobeda. I have a Polish version, the Warszawa. Both are very rare in the USA. Steve

The Endless Mountains Antique Truck Show and Flea Market scheduled for Sept. 5th, 2020 has been cancelled . This would have been our 30th annual show at the Harford Fairgrounds in Harford PA. We appreciate all of the support you have given us in the past. The Northeastern PA Chapter , ATCA hopes that you can join us on labor Day Sunday 2021. Steve

I like the International with the backhoe . That must have been a fairly popular idea in the fifties, I have a similar setup on a Dodge chassis.
