What is the Model number and serial number on your truck. Should be a B75F with a 464 engine and Hale 750 pump. Oil should be Shell Rotella T SAE 40W do not use multi weight oils in the old gas engines. Also needs zinc so that is why we use Shell Rotella T SAE 40. I usually special order and buy 6 Gallons at Napa.- it will need about 5 gallons. fill up with 3 gallons and top up using dipstick until full. Oil Filter is NAPA 1503 Delco Distributors All ignition parts still available I use the Brillman Company for plugs, wires, caps rotor etc. AC Fuel pump can be rebuilt by Kanter Bros in New Jersey Carb should be a Zenith updraft can be Rebuilt by Carbs R Us Torrington CT

You can also have the original fuel pump rebuilt by Kanter Auto in Boonton New Jersey. About $88 including shipping. Good Luck Firemack

Thanks Randy, He is my project dog follows me everywhere to see what I am doing. If I go out to garage he will lay down at the garage door until I come back in. He loves to go for rides and loves people so a parade and muster was right up his alley.

I got a call from an old friend earlier this year that asked me if we would bring the Radnor B75 to the Wilmington Delaware Fire Departments 100th Anniversary Parade and Muster. For fun during the Covid break I tore down the Hale pump with some help from The Famous Supplee Brothers -Dan and Bill from Oreland. It took longer to rebuild the pump than it took to restore the whole truck, but got it wrapped up in time for Memorial Day. During the pump rebuild I had time to clean and paint most of the frame, pump and running gear, so most the hard work was complete to detail the truck for the Wilmington Parade. The night before decided to take my dog Gambit to the Parade- he is a large sheltie but makes a good imitation Dalmatian! Wilmington had 4 B75 pumpers and 4 B95 pumpers. 2 were in the Parade and muster. Over 100 trucks attended and a total of 6 B model pumpers were at the Muster! Had a great time at the Parade and Muster. We have to congratulate the guys from WFD, they did a great job organizing the parade and muster. We were honored to be awarded first place 1950-1969 Fire Company owned Truck and Gambit won the Mayor's Choice award. We

Just did the same check on a 1951. Check for power at the coils when you turn on the ignition. The if you have power at coils then check on the other side of the coil while cranking. If the test light goes on an off the points are working. Next check the rotor and cap, sometimes the rotor gets rusty and wears down the cap. Next Check for spark from coil to coil wire . Then check for spark at plugs. If all else fails replace with the pertronix, however you also need to replace all of the wires with Carbon wires to keep the warranty on the pertronix. I just replaced the wires rotor cap and points with Pertonix, Added fuel to the carb and the 51 L85 started right up. You can buy all of the parts from the Brillman company John Brillman owns an old autocar. www.brillman.com 540-477-4112. Tell him the distributor number and engine and can ship you everything you need. Have fun looks like you are making good progress. Firemack

The other option is go electronic ignition, I did a write up on that a few years ago when I swapped the points out on a 707 in a B95. You can search for it on the site and find all of the info and I purchased the high quality cap rotor wires and other parts from John Brillman. He actually has the template to make up the original wire sets with the Packard 440 original type wire and Pertronix electronic igntion. His number is 540-477-4112 or www.brillman.com. He also has the old truck disease (Autocar). Firemack

Glenn I am rebuilding my QL-1 (QL 75) pump and transfer case now on the 1954 Radnor B75 Mack (464 engine Hale 750 pump). I have the original Hale book and parts list and just purchased all of the bearings new (stock parts) the only part not available is the center bushing between the impellers, the front bushing is the most important and still available, I left you VM if you want to call and discuss.

Have a friend working on a 1945 Mack E series Fire Truck with the Continental engine and needs an Exhaust Manifold. The front section has cracked and needs a new section or complete manifold if anyone has one available . Could either be a 290 or 330 CI. Part number cast in the manifold is M 600 E 407 H. Message me if you have one or know a contact that may have one. Worst case if needed we can weld it up, but if possible would like to get an original part in good condition. Thanks Firemack

Glenn, I switched to K&N air filter, K&N made it to fit right in the original Mack Chrome air cleaner. Replaces the original steel wool air cleaner. You can contact K&N and they have filters sized on what you need to fit in the original mack filter and engine displacement. Firemack

Engine 1252 You might want to consider changing over to electronic ignition to improve the performance and remove any chance of the points and condensor causing any problems. I used a Pertronix electronic ignition module for a 12 volt positive ground system. The parts are still available at NAPA but I like the quality of the parts from Brillman Company- he uses all brass fittings etc. I still purchased plugs from NAPA- AC R45. The points, condensor, (or electronic ignition module), cap, rotor and wires, I purchased from Brillman Company in Mt Jackson VA. Contact John Brillman at 540-477-4112, he is a nice guy, and you may see him at a VA truck meet as he has an old Autocar tractor. Once you install the ignition parts you will need a regular timing light attached the positive (red lead) and negative (black lead) of the battery (and the timing lead connected to number one spark plug wire on one of the distributors at a time). The timing light does not need to reversed for positive ground and will most likely ruin the timing light if not correctly connected. You can use a engine dwell tach or engine analyzer with the red lead connected to the primary wire of the distributor (Ground) and the black lead connected to the ignition hot at the coil. This can then be used to set the dwell (if you decide to use points and condensor) or to monitor the engine rpm to set the idle mixture and idle speed. Timing on a 707C is done on the flywheel under the truck not on the front pulley. You set the dwell and then set the timing. Do one distributor at a time and it makes it easy to get the truck started (on the one you have not changed) and then adjust the timing on the one you just updated. After setting the dwell and timing on both then set the idle mixture for the highest idle speed, then reset the idle speed. I usually set the idle at about 600 rpm but can be set as low as 350 if you like it there. If you mark the wires and send them to John Brillman he makes the original style (Packard 440) wire sets in the exact size of the wire set you send him and is reasonably priced (a little more than Napa). This way you have an exact replacement wire set and not some mix and match from a parts catalog. Good luck, Firemack

Check the drag link , it has 2 adjustable ends that have large screw type threaded ends that can be tightened to reduce the play, if the buttons are popped up then they need to be adjusted. If you have a manual will show how this is adjusted, but basically loosen up the end squeeze down the end play buttons which pop up when too much end play and tighten them down again.

B Models with Juice brakes have a round hole about 4"' in diameter locatedunder the drivers seat. Uses 2 screws to hold it down. 1 screw comes loose to rotate it out of the way to check the master cylinder.

Our 1954 Mack ENF464 gets between 1.0 to 3.5 MPG. 1.0 around town, 3.5 down hill on the interstate.

Yes it was painted yellow. That was a good reason to do all of the work to repaint the truck, so we bead blasted the whole truck back to bare metal, repaired or replaced all of the rusted panels, then painted each piece individually and then assembled, as well as rebuilt all of the mechanicals, used 21 gallons of red paint, plus primer, clear coat and silver. The paint was donated to the Fire Company by Sikkens. We drove it back from Vermont on July 20, 2002, started the restoration in November 2002 and was in the first parade in May 2004.

Malvern Fire Company in Malvern PA has Mack B75F0001, the first of the B75 Fire trucks delivered in July 1954, Radnor Fire Company (a neighboring company) must have liked the truck, so they ordered a twin B75F Pumper in July 1954. Radnor B75F0011 was delivered in December 1954. They responded to many fire calls together over the years. The Radnor Mack was in active service for 48 years until 2002. Both trucks are now in semi-retired status working at parades, shows and other events throughout the year. Big Mack Website members may have seen the Radnor Mack at Macungie or Lititiz this year. This past Saturday, October 13, 2018, both B75F pumpers they were together again at the Main Line Fire Prevention Expo in Devon Pa, providing fire truck rides to over 550 participants. It is very cool to see a matched pair of Mack Firetrucks still working together after 64 years.

I have a 464 also in a B75 Firetruck- I sent mine to Kanter Auto Restoration http://www.kanterrestoration.com/ They rebuilt mine like new in about 3 days cost $84 but that was a few years ago. They normally do AC Fuel Pumps for chevy's etc. Just call them and let them it is a regular type AC Fuel pump and you know another guy that had a few rebuilt by them and are still working. Firemack

We have 2 Rosenbauers here in our township, both have been in the shop many times, The 2009 Bryn Mawr Ladder more than 2010 Radnor Ladder. Bryn Mawr just put their truck up for sale. My guess they will be buying an E one to replace it. Our 2010 (the next one built on the same line) used a Spartan Cab, which was fine until 2 months ago when it burned the entire wiring harness. $27,000 and 2 months later we get it back. I doubt it will ever be right again. Can you say Quality is job 1? This truck was ordered and we were told they would make the engine and trans work for our district (adjust the shifting etc.) . We replaced a 1993 One Ladder, it weighed in at 52000 GVW with a 500 HP 8V92, The Rosenbauer weighs in at 73,500 with a 500 HP cummins ISX. What a dog- goes just 22MPH up our longest hill in our response area versus 38MPH for the E one. I don't think they will sell another Rosenbauer in this area for awhile.

GA- Dave, Thanks for posting great shots of some very interesting Mack Firetrucks, shows the great diversity of types of Firetrucks Mack could build. Maybe someday they will wake up and smell the coffee that there is still a market for the types of Firetrucks they can build.

Yes the MH was a Ralph Smith Tractor- Ron Smith has the 39 Baby Mack- he is on the this site and was one of the original owners that cared for the MH over its first 25 years and 1.2 M miles. It has been hauling the Radnor B Model and Radnor Hahn on the lowboy to shows more than 50 miles from Radnor. It was tough on the B model going 50 on the turnpike and getting blown off the road by modern trucks that are doing 75 and not paying attention, almost got hit several times. The B model gets about 1 MPG around town and 3.75 going downhill with a tailwind, the MH gets about 5-6 with the lowboy attached and B model on the trailer at 73 MPH. Check the garage for the picture of the MH as it was set up with the stainless horse trailers, hope to someday buy the Ralph Smith Horse trailer and make it into a travel trailer, if I can ever get the wife to get on board! Ron that was a typo, 1.72M Here is the the picture with the original stainless trailer. That was great looking combination!

Check Watts Mack, they may have a replacement Tie rod from the R model that may work, it worked out great on the 54 b Model. Firemack

FDNYMACKCF Great job on rescuing another one! Here is another one of the few Open Cab CF's, this one is a gasser and had a blown piston, this was taken coming back from the paint shop in PA, hope yours makes it back to NY so you can show it with this one. This was a week before rescuing a FDNY truck last year (night shots). Both are safely stored and hopefully the open cab is getting ready to make it Harrisburg pump primers this year. Firemack

Very Cool! Thanks for posting!
