gmbelt Posted May 28, 2009 Share Posted May 28, 2009 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 help as to where I can start looking and the likely cost would be appreciated.Many Thanks,Gary M.

Rob Posted May 28, 2009 Share Posted May 28, 2009 Gary, chances are that someone either used readily available emblems, or the hood has been changed through the years but it is hard to say. I don't know where to tell you about a manifold but yours could possibly be repaired as I've done several. Snap a photo of the manifold so I could evaluate further.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Firemack Posted May 28, 2009 Share Posted May 28, 2009 GaryThe B75 had a 464 or 510 engine and 750GPM pump, (and there were only 54 built). The B85 had the 707 engine and 750GPM pump. so to confirm you should check the right frame rail above the front axle to see the serial number which is stamped in the frame and should be able to confirm if the serial number starts with B75 or B85. If it was a B75 someone swapped the engine or a B85 and someone swapped the emblems.Firemack Quote Link to comment Share on other sites More sharing options...

BeltManassas, VAI forgot to ask earlier: Did that truck belong to the Bureau County Fire Dept. in Illinois? They have a very nice B model tanker that they still run and it is only about 70 miles from me.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Is it definately a 707? Or as suggested someone put parts on, or you have a one off oddball that was custom ordered. Quote #1 on A-model registryIf I drink because of work, why can't I drink at work?

Firemack Posted May 29, 2009 Share Posted May 29, 2009 Greg,The grill shells are identical on the B75F,B85F, and B95F so the only way for Gary to confirm is using the frame rail and see what the truck was from the factory. Firemack Quote Link to comment Share on other sites More sharing options...
b61fred Posted May 29, 2009 Share Posted May 29, 2009 hi, I dont know why but the fire trucks are numbered differently than the regular trucks, I have a guy that has lots of 707 parts, if you have a 707 that is. The best way to find out what engine you have is to look for the engine number. should be en707.. The man with the 707 parts number is 1-256-233-2336 name is bob hickman. He has two engines that he is parting out. Fred Quote 15 gears...no waiting! Link to comment Share on other sites More sharing options...
