Ford 460 Cooling Question
I am a volunteer firefighter in Pa, our squad truck is a 1983 Ford E-350 cube van with a Ford 460 motor in it (drinks gas at a rate almost comparable to the 477 in my personal fire truck)... we have been given a 6kw Onan PTO generator that we are thinking of putting on the squad truck. Here is the problem though... this d$$$ generator needs an engine rpm of between 1,800 and 2,000 rpms... I know that the 460 will turn those rpms with no problem.. the question is will it be able to turn those rpms while the truck is not in motion (it is not a hotshift PTO generator nor can it be operated while the piece is in motion) and not overheat. My biggest fear is that the poor motor is going to overheat (it has never had to pull this kind of duty before)... we have a mechanic who says it won't... but I am not so sure.. so I figured I would get everyone's opinion on here since you guys would most likely know better than our mechanic guy (who sufferes from ****-Cranal Disorder).
Thank you,
Dave

Well, that is the problem.... it is very hard to say... if we are out at a vehicle accident that is minor it might only be maintaining that throttle for 30 min to an hour.... if we are at a fatal accident it could be running that rpm for 5 hours or more while the investigation takes place and so forth. It is sort of hard to say with the fire department... there just isn't always and everytimes involved

That is what I said too!! I can't imagine it not overheating if running in that range for 5 hours.... everything else we have is diesel (1 Detroit 6V92 and a Maxidyne (Mack) 300) which both are made to run like that.... I was pumping with the engine (Detroit) for 10 hours one night at 1,700 rpm while supplying a 2,000 foot hose lay of 5 inch hose. I have seen some gas motors do the same thing, there is a Ford C pumper with a 534 motor in it that has done it's fair share of pumping (particularly running a tanker fill site from a creek where it ran at or above 1,500rpm for 14 hours... but with extra cooling from water diverted from the pump through special cooling lines)...but I can't imagine the 460 in the squad truck doing something like that. We should have gotten rid of it years ago..... but it still runs so we keep it
