The engines the KME's are set to replace are now getting long in the tooth, thankfully however, the era of Seagrave that the KME engines are replacing were the end of the line and were proven pieces, with all the niggles and snags ironed out, and are true workhorses, perhaps with one or two exceptions.
A colleague of mine visits a couple of Bronx Firehouses a few times a year, two of which still run the old seagraves set to be replaced by KMEs, and both engines feature constantly and without fail in all the reports and research i do, E75 and E42, also.
Another busy Bronx engine, E45, also runs an older seagrave.
I can only say what my colleague has passed on, but for E75 and E42, the apparatus will pump water until they disintegrate, and E75 and E42 pump water two or three times a week at workers.
With a bit of diamond plating on weather prone areas, the bodies are holding out, the only real complaint is they have no power left in the engines at all on runs, with many hills on 42 and 75 s areas, they crawl up hills often with the engine and gears screaming.... And the rig going nowhere fast!!!!
Yes KME is big in LA, and Boston, and other cities, but to,be honest...
Will the KMEs be able to withstand such abuse unique to the FDNY... Especially in the terrain demanding areas of Da Bronx with hills and atrocious roads..
Will they stand the test of time and abuse... Or be 'Hanger Queens'...
Time will tell in a very short space of time i feel...
