Day One: 11-16-14

Me, my dad, and my uncle went up to Chesterfield, MA to look at 'Mater, a 1964 B61SX. We got there about an hour before dark to check the truck out. It was quite cold. The dump body was up a little bit, sitting on 6x6" blocks and it was full of frozen mud and scrap metal. The tailgate was down and chained about level with the bed and it too had mud frozen on it. The ears on the driver's side of the body were bent, not allowing the tailgate to be brought up and pinned in place. The owners had it plugged in (block heater) so it would start, and once we had it going, we were impressed with the sound of the engine. It ran cleanly with no hesitation. The body work (fenders, hood, cab) all appeared to be in decent shape, although the paint was not. The interior of the cab looked to be quite salvageable, too. The tach and speedo worked, not sure about any other gauges. The driver's seat bottom was bad, but all other cushions were fine. My dad drove it in the yard, but it didn't like being shifted (the owners apparently hadn't done much shifting in the years they had the truck, and like I said, it was pretty cold out and who knows how old the trans oil was) and it wasn't building any air, so there were no brakes. We put the truck back and while my dad and uncle continued pouring over the truck, I offered the owner (Barb) $2,500 for it (she was asking $3k). She accepted the offer and I thanked her and told her I'd try to get back that week to pay for it and pick it up. Both my dad and uncle were surprised and impressed with the condition of the Mack, given that so many times stuff like this turns out to be junk. This truck clearly isn't in that category. Having said that, there is no question that it will need a significant amount of fixing and tinkering just to get it to the point where everything operates and does what it's supposed to do. It doesn't appear that regular maintenance was a part of this truck's life for quite a while, so we'll have to remedy that as well. One humorous part of the visit happened almost as soon as we got there. One of us asked about the steering, and Barb's husband said, "Oh no, it doesn't have power steering. In fact, it kind of steers hard." Well, my dad climbed up on the fender, opened the hood, looked down, and saw a power steering pump and cylinder. Of course, the reservoir was empty. Pics will follow.

Looking for the right dog

G'day to all I have a B61 and recently while going to a old machine day I noticed he's the wrong bloody dog! He is a modern smooth ear for pulling the bonnet (hood) over to get at the engine. Would one of you fine ladies or gentleman have a picture of the correct dog mascot for a B61 1961 model? Thanks in advance Regards Chris BTW Bonnet is oz for hood Glovebox is oz for glove compartment And the boot is our word for trunk! Confused? Enjoy!

Has anyone used the Mack engine rebuild program for E7 engines? I have a 2001 Vision E7 with a busted roller tapped. How much does it cost to rebuild the engine with Mack's Remack program? Is it a smart way to go? What are the pros and cons, etc. Thanks

Help 1989 Mack 350 dies under a load

Loses its prime when sitting then hard to start . The truck will start and idle and rev up fine but put it on the road and it dies. It also doesn't want to build rpms unless going downhill. It will restart after it dies and idle and run under no load. Changed fuel filters twice. The fuel is probably two years old but looks and smells ok. Where do I go from here? Thanks Gents.

Spicer Auxiliary transmission

I had ask for help in a earlier post, locating a Spicer 5831A gear box. I have had a lot of response helping me locate one and others have given suggestion on the installation. I would like to Thank everyone for that. But It has been pointed out to me by several, that the 5831 may be a little small going behind a old 300 Mack engine, and that a 8000 series Spicer would be closer in line with the torque. NOW! the question is does anyone know where I might find something like a 8341 which is a 4 speed. I am not sure which model number was used for the 3 speed and would be interested in either one. I would like to still have the .73 Overdrive but again have been told that they are very rare. .84 will work. Any help would be appreciated. Thanks Don

Need help with End 711 Gaskets

I am tearing down my 1965 B61ST. Need to get the engine cleaned up and painted. I have decided that it would be much easier if I remove a bunch of the plumbing as well as the exhaust manifold and valve covers (valve covers have a gasket leak going on anyway). Can anyone tell me where I can purchase another set of intake and exhaust manifold gaskets, and valve cover gaskets?? Engine is an End 711 (non-Turbo). I would appreciate any help on this I can get. Thanks, Razorback11

Need advice on 2003 Mack cx612 with wiring problems and engine noise

Hello all, I am looking at purchasing an '03 mack cx612. First question is the turn signals blow the fuse everytime they are used. I have not looked at the wiring yet but was wondering if there are any common problem spots in the turn signal circuit. Second question. The engine is a E7-460-P. What does this mean and how reliable are these engines. It has just shy of 800k on it and the current owner bought it at 400k. He has never had to do anything to this engine. Is it a "million mile" engine or is it ready to blow?. It has been sitting for awhile and was quite cold when I started it. It did not smoke at all and started easily. It did seem to have a "tic" in the top of the engine toward the back. Valve train noise? Normal or not? The owner is not a mechanic and said it has sounded like that sense he had it. He is offering me a very reasonable deal. Should I run or buy. I Know it is a lot of questions but I would really appreciate any help on this.
