I have a 1948 3600, that has a factory installed ( I am told) hydraulic pump for a bed dump. Does anybody know any details on this, mine is not currently operational due to leaking seals on the lift cylinders, that I hope to soon fix. Any info on this setup would be appreciated . See photos

The link seems to be requiring a Dropbox account. The best option to ensure accessibility (and longevity) is to attach the photo directly.

Dump beds and their hydraulic pumps were dealer, third party vendor or owner installed, they were not installed at the factory.

belt driven means it is running the whole time the engine is on, pumps wear out even if not under load, but it's gonna be a functions of the pump quality and the cleanliness of the oil circulating in the system

i think when a pump is direct connected to an engine it's referred to as a "live pump"
old timey tractors had options for live pumps and ones that were engaged via gears and the clutch for this reason

the live pumps were not ordered as regular equipment unless there was a good reason for it
my 1950 farmall tractor had a live pump, it is so worn out it could not operate anything,
it has the same big round filter as in that first photo

With a little creative machining it might be possible to adapt an air conditioner compressor clutch to a hydraulic pump to avoid the problem of the pump running all the time. I don't know if the torque capacity of one of those clutches would be sufficient for heavy hydraulic loads, however.

could this be a cause of slow turning I have been having?

I'd suggest (wait- - - -I already have) removing ALL the belts to evaluate what's happening inside the engine. Once you figure out if there's an internal problem, start reinstalling belts one at a time.
