  1. As always, your advice, help and guidance are invaluable. Many thanks my friend, Gary
  2. My 1962 B-85F semi-open cab pumper with a Mack Thermodyne ENF-707C gasoline engine is need of a major tune-up. My mechanic tells me that it could use new plugs, plug wires, points, condensors, maybe new distributor caps, etc. He also said I would need to find a "dual" timing light because of the dual ignition on the engine. He also noted that one of the distributor caps was sitting on top of a device a little bit larger than a soda can; no idea what it is. In any event, I'm looking for a source for these parts and would greatly appreciate some advice as to where to turn. I can provide any
  3. Firemack: According to my mechanic, the NAPA 1503 oil filter I purchased for my Mack 707C engine won't fit. The mechanic tells me it is too small and the Napa 1503 won't slide up on the "shaft" because the center hole in the filter is too small. I know the NAPA 1503 is about 1/2" smaller in OD, but how do I get it to go on the shaft? Many thanks, Gary Manassas, VA
  4. As always, many thanks for your help. Gary
  5. Firemack: You recently advised that Shell Rotella T SAE 40W oil would be a good choice for my Mack 707C gasoline engine. I note that Shell has this in 5W-40W and 15W-40W; which should I buy and how many quarts does the 707C need? Also, I read the old posts from last fall about the issue of oil filters for the 707C. Was that ever resolve as to what would work as a replacement? Barry's shop advised me a couple of weeks ago that the Mack 236GB222 oil filter crosses with FRAM C147, BALDWIN C36M, and NAPA 1237; none of these appear to be made any longer. They also crossed it to the WIX 51503 wh
  6. I have been told that the exhaust manifold from a 673 diesel, 170hp, will work on my 1962 Mack B-85F fire truck with a 707C gasoline engine. The source of this information said that he had a cracked exhaust manifold on his 1961 Mack B-70 tractor with a 707C and the 673 diesel, 170hp, exhaust manifold worked fine since the engine blocks are almost identical. He said the 673 diesel exhaust manifold is easier to find. Any thoughts or experience you folks have in this regard would be greatly appreciated. Is the 673 the END673 and if so, does anyone know the letter for the 170hp, i.e., A, B, etc. T

  8. Rob: This 1962 Mack (with a 1,500 gallon tank) hails from the Eastwood Fire Protection Bureau in Carter County Missouri. Gary
  9. I'll check the frame rail the first chance I get. Any suggestions on locating an exhaust manifold. Gary
  10. I have a 1962 Mack fire truck; the Mack manufacturers plate by the pump panel says Model: B85F. However, if you look at the attached photos, you will see on the hood the emblem that says "B75". The photo of the other side of the hood shows the emblem missing, but you can see the outline of when the emblem was there and it also says "B75". Is this just a case of someone using the emblems available at the time? I also included a photo of the entire truck. Also, the mechanic tells me that I need to replace the exhaust manifold which has several cracks in it. The engine is a Mack 707 and any
  11. First, thanks ever so much for your help. I'm not mechanically inclined, so please pardon my ignorance as to what is probably basic stuff to most of you folks. For instance, the Shell Rotella T SAE 40w oil, is there anything that needs to go in front of the "40w", i.e., 10w, 20 w, etc? Secondly, I've done some searching through the posts on BMT and it appears that oil filters for the 707 gas engines are almost non-existent. Any help on where they can be found or a suitable replacement would be most welcome. I've tried to attach some photos of the carbruetor and air breather in my 1966 C-95
  12. I just acquired a 1962 Mack B-85F open cab pumper that has what I believe is a Mack ENF-707 gasoline engine. What type/grade of oil should I use in this engine? Also, I'm looking for a "cap" that looks like half of an oil filter or a bullet that screws on over the area of the exterior wheel where I think the bearings are located. The 1966 Mack C-95 open cab pumper I have needs the hose/plastic pipe the goes from the carburetor to the air breather that looks almost as big as a five gallon bucket. As always, your help is appreciated. Regards, Gary M. Belt Manassas, VA
  13. Many thanks for your help. Gary
  14. Looking for a good source of parts for a 1966 Mack C-95 pumper (open cab). Specifically looking for a rebuilt carb. for Mack ENF707C gas engine (as well as other possible engine parts). Also looking for new steering wheel before the current one comes off in my hands. As always, I greatly appreciate the help I receive from this group. I am a novice (non-mechanical person) and your assistance is invaluable. Many thanks, Gary M. Belt Manassas, VA
