  1. 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
  2. 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
  3. 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.
  4. 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.
  5. Our 1954 Mack ENF464 gets between 1.0 to 3.5 MPG. 1.0 around town, 3.5 down hill on the interstate.
  6. 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.
  7. 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.
  8. 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
  9. 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.
  10. Need some help with tune up specs for a Mack 707. this is a fire truck engine, dual plugs and distributors. I am not sure what year it is or what particular model.  What is the "ENF" 707? Is this a 707B since it has dual plugs? It does have Delco-Remy distributors and coils, finned rigs that bolt onto a bracket with four bolts each.  Where do I find identifying info on the engine?  Also, need simple things like point gap and plug gap. It has Motorcraft A-7 in the left side, Autolite 315 in the right side.  Will Champion J8C work? Seems to me most of those old large engines took a J8...

     

    Thanks for the help...

      ENF 707 if a fire truck block, with dual iginition.

      I will check my spec book and get back to you with the proper info.

      You can switch over to electronic ignition, they make new replacement electronic ignition for the delco distributors you have and with positive ground.

      Also have a supplier for the cap, rotor, plugs and wires.

      I did this same work on a 1960 B model enf707.

      Replaced, with electronic ignition, new cap , rotor, wires, plugs, fuel filter,

      Runs much better

  11. 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.
  12. 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!

  14. 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
  15. 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
