F-450 Diesel: Converting hours to miles

Considering a '96 F450 SD, diesel w/ 5 speed. The truck has an undereck compressor fit to it that runs off the PTO. The transmission has been rebuilt. I notice that these tucks set up like this tend to have rebuilt trannys. Is that just a function of running the equipment all the time, or is it more likely neglect. Also, the truck only has ~39k miles on it, how do the hours on the compressor unit translate into miles on the engine? Any thoughts on what to look out for on this truck would be greatly appreciated. Thanks

Matt

Miles on the engine and hours on the compressor are not related. The engine runs to drive the compressor, and depending on the engine speed, this can be virtually any speed. My '95 Bronco goes nearly 60mph at 1500 rpm, so if I ran a compressor at that speed for 10 hours, it would work out to 600 miles, I suppose.

Personally, my thought is that any truck like this is going to be a unique experience. Work trucks can be treated well, or treated like shit. There's no real way to tell, other than (perhaps) physical appearance. If it looks good, it might be, if it looks bad, it probably is.

The truck has only 39k miles but the trans has been rebuilt. Do trucks like this tend to have rebuilt trannys because of running the equipment all the time, or because of neglect?

The original owner bought an F450 SD and drove it less than 4,000 miles per year for 10 years? Such an almost brand new truck should not need a replacement trans unless it spent its life carrying loads in a rock quarry.

You can calculate approximate miles by first estimating the average speed of the truck while the compressor was operating. When estimating average speed, factor in highway, city and idling speeds:

(average speed) X (compressor hours) = Miles

Example: (30 mph) X (1,300 hours) = 39,000 Miles

Good luck.

Thanks all... I guess that's about what I figured, that it is more or less a crap shoot.

Mr Strickland, how is it that you seem to be in every group I regular? Jeep, BMW, Ford truck... think there was one more... are you in them all? Because *that* would be impressive.

Yep, I have a Jeep, 2 BMWs, and a Bronco. I formerly had a Toyota truck, so I hang out on the Toyota truck and the Toyota boards too.

The transmission pans rot out, all I really know about these trucks.
