933Scope

Thanks for the responses - truck is a 1988. If I were to get the truck, no plans to try to get more HP out of it. It is a single axle with a 29,900 GVWR, max GCW would be maybe 40k lbs or so. I drove many Detroit 6V-92s with Allisons in my volly FD days; performance in a 35k lb pumper was adequate from my experience. I'm assuming a 285 Mack would perform as good or better than a 6V-92?

Not all that much experience with Mack engines - looking at an older Mack with an EM6-285. From the limited website info out there, seems like a reliable engine. All mechanical I assume, are parts still available for these engines? Engine is backed by an Allison HT-740. Drove many 2 cycle Detroits with Allisons in my years as a volly fire fighter, but no Macks. The only Mack fire apparatus I remember was a 70's Aerialscope, but I never drove it. Also, with a VIN, can a Mack dealer provide drivetrain details on specific chassis? Thanks in advance for any info.

New member - great forum. I've been looking to purchase a historic piece of fire apparatus and finally got a chance to inspect one for sale that is within my budget. FD had maintenance records that I went through. One note I found on a repair order was likely from the mechanic doing some brake work (air brakes). It stated something to the effect that the air/brake lines were hardened and beyond service life and should be replaced (about 26 yrs). It didn't seem as though this was done. Would this be expected for a 25-30 yr old chassis and anyone have a ballpark on what this would cost? I'm assuming this is replacement of nylon/rubber material lines and not metal. Flexible, non-metallic lines would seem easier and less labor cost to replace, but maybe I'm missing something or my assumptions aren't accurate. Thanks in advance for any information.
