No Bulldog on hood (replaced by handle) is sign of NYC -Dept of Sanitation (DOS). Not sure about the departments. The bulldog gets stolen. They still do that (without Bulldog variant). The red truck (RD?) has a handle.

Not sure if this post should go here or under engine. But, the Engine section looks like its a lot of more modern engine questions and I don't think it would get the best response there. The question I have is, what's inside the tube that comes out of the rpm limiter (cable, chain, or some kind of tube)? As you can see from the picture, we received the truck with no air cleaner. So, before we do the compression test, I would like to take the Zenith carb off and make sure there's no critter nest inside. But the tube from the limiter goes into the base of the carb, and makes getting to the bolts hard unless I disconnect it.

The numbers on the engine, that I took picture of, were on R/S lower block. Sort of down between Air brake compressor and distributors. (fire truck, gas engine, and hook & ladder so Air brakes. Distributors (2) are where the diesel fuel pump would be)

Hi Robb, Sorry I don't know the year of their B-Model that is in storage. Since I am a Mack truck employee (until Friday 1/10/25), and also a Mack, Doug the curator allowed me to climb over the truck to get some reference pictures to get our '57 B85F open cab going. There was a lot of stuff that made it a tight climb, so they might not allow someone to go into the storage area for insurance reasons. (As an employee, in a company owned facility, I would be covered.) But, maybe if you contact them, asking for a certain picture............

Here are pictures I took of the B85 enclosed cab firetruck that is in storage at the Mack Historical Museum. Taken 12/23/2024. I was looking for reference pictures for how things are laid out for our restoration of an open cab '58 B85F hook & ladder tractor.

I got chance to go to the Mack Historical Museum on December 23rd. I had some stuff to drop off (framed pictures that once hung in the old World Headquarters). I also wanted to talk to them about my brother Jack & my B85F. And to take pictures of the enclosed cab B85 firetruck that they have in storage for references. It's in original condition, but needs going over. Plus, my Mack Trucks employee badge is getting turned in Jan 10th when I retire, so I wouldn't be able to "badge" thru the front gate soon. (note: since Mack Defense has a small assembly line in the facility, the gate is now manned by a security guard). After looking at their B85, the curator Doug Maney asked if I submitted a request for info. I told him yes, back in the end of November. He said that we should be coming up soon. Then he asked if I wanted to see the build sheet...... My response was "Of Course". Yes, I held the build sheet in my hands. Our truck (B85F-1211) was third of three trucks on the order (see picture). The order sheet has engine, trans and axle serial numbers. And, if it's anything like how we run now, it's a "as planned" number. It looks like we have the axle from 1210. Not sure the number on engine is a serial number or a build date number. The number of characters in the serial number doesn't match the stamping. I haven't tried to contort myself to find the trans SN yet.

Nice, hope we can get somewhere near that HP once we get our engine running. Here is what's stamped on our engine, lower right side of the block...

Weak spark could be multiple things. Dirty points, Condenser on it's last legs and as you state, the coil going bad. Do the cheap stuff first....... - I would first do an Ohm reading on the coil. Sorry, I don't know the spec off the top of my head. Usually 2 to 4 ohms. - The condenser should be 0.25 uFD. I know that because I have a real condenser tester (old school) and just bought new ones from Brillman Company in Virginia. Also found out the rusty ones someone had in our cab were also reading good (including a old Delco-Remy one). - Points.... run 800 grit or higher sand paper across them. The black colored sand paper will show a white trace if there is corrosion build up. If you get a trace on the paper, do it again until you don't. And finally, something you can't see on a distributor with a cap is the sign that a condenser is on it's last legs. The points will be arcing when the engine is running. That arcing is what destroys the points. On things like lawnmowers, Old motorcycles, minibikes and some generators, this is a handing thing to know. Tom M.

25 ton bottle jack are still an available option on new Mack's. Not many people order them. They take up space and the service truck that comes usually has them.

Signal-Stat still makes the column turn signal thing. Mack still using a similar one on the COE truck (MRU or now called TE) that are made today. It doesn't have the indicator light in it since that's in the dash panel.

found it, see attached. Again, not sure it's the same, but the fuse panel looks basically the same. Mack-Fuse-Listing-2013.pdf

From the factory the list is taped in a sleeve on the fuse panel cover (also called the pie plate). Some where I have a list from 2013. Not sure if it's the same as 2008, but it was same as 2011, when I started at Mack.

That's called "Park Brake Lighting". It's still an option on brand new Mack trucks.

Are they the "Low Entry" LR models?

Mike, are you related to Mark? I meet him at Trucktober Fest this year and have his card.

TE = TetraPro, which was the MR or MRu.

Trolling for a while.

The Low Entry refuse model "LR". AKA Garbage Truck. Diesel (Mack Eng,) and CNG (Cummins Eng). Steering configurations: Left hand only, Dual position (R & L) and Right hand only. Note: it takes about 4 or 5 turns to get use to switching to the RH steer, You still use the Bulldog to line up in the lane only instead of the white line on the side of the road, you use the Yellow center line, but still un-nerving pulling in to a garage bay. Also, the model that was formerly called the MR of MRU. Now TE for TetraPro. Same basic design for 30 years. Diesel Mack Eng (both sizes) and CNG (Cummins Eng). It comes in the following Axle - Drive configurations: 4x2, 6x4, 8x4 (dual steer axles), 8x6 (Tri-drive), 10x2 (odd looking - dual steer axle, 1 drive axle and the rest drop axles), 10x4 (Tri Steer), 10x6 (Dual Steer, tri drive), 12x6 (Tri Steer, Tri Drive) and the 14x6 (long and doesn't turn on a dime)

If it follows current scheme, and it looks like it does....... 1 = USA M= Mack trucks 2= Incomplete vehicle which means it was heading to a body builder. 1 = would be complete vehicle , basically a tractor. N2 = model 08C would be a engine, trans, axle combo. (really big list that actually has some logic to it.) 9 = parity bit. It's something used to double check that the number gets transmitted electronically correctly. C = year made A = plant (I would think that means Allentown) Macungie is "M" 003715 = Chassis number.

According to the Mack Museum, Mack made trailers from 1927 through 1944. A guy at work has his father's old title for one. The trailer is long gone.
