I think I read something about the power steering pump deal too! Would it provide enough volume to operate a large cylinder for a dump?

I think it would be slower than the pump thatís there,the power steering pump on the bus should fairly good volume and pressure,depending on the load in the box

Geared correctly, I'd think that snow plow pump motor or for that matter a starter motor could easily turn a hydraulic pump... I'm sure there is someone on the site that has the engineering ability to compute what gearing would be needed to turn a pump designed to produce sufficient pressure to power the dump box... but I'm sure you'd have to have the pumps max pressures and such but it might be the volume of fluid required to be moved might be the deciding factor... Now I'm confused....lol

Yeah Iím not hydraulic engineer either. All I know is the thingy thingy turns, and when I pull the lever, the round thingies push the bed up. I just need to find another way to turn the turny thing 🤣

Northern Tool and some others sell a number of 12volt and 24volt electric hydraulic pumps with motors and reservoirs .... just a thought...

McMaster Carr has a bunch of hydraulic stuff to look at, too.

The pump on the bus should put out 2300 psi and 4 gpm

I built a scissor lift under the bed of this truck and used a 12 volt electric over hydraulic, power up and free flow down pump with a 1.5 gal reservoir that worked great. The free flow down is faster than the power down (you could incorporate both in the system)
The cylinder was 16 inches long with a 3.5" diameter.
The bed would go up twice as high as the pic shows.

I installed a lot of DewEze and Muncie Power belt-driven clutch pumps when I was a truck equipment mechanic, and they worked great. Put it in neutral, flip the switch and get all the hydraulic pressure you need. I am sure there is a kit available for your engine. Routing the hoses can sometimes be a pain, but on that truck you should have plenty of room...
