LaPlant Choate scraper hydraulic pressure questions

[ChrisUK]

Hello all, have managed to acquire a LaPlant Choate single axle scraper as shown in picture
Needs some work before use but seems all there.

The hydraulic ram that operates the scraper is of quite a size, is this because hydraulics were at a lower pressure back in the day ?
My thinking is if the pressure was lower it would need a larger surface area (hence large diameter ram) to produce the necessary force ?

Would anyone know what pressure these were meant to be operated at ?

Also would anyone know what colour it would have been as I have only got black and white pictures.

Will eventually be going behind my D7 3T

Thanks for the help
Chris

A quick look at other scrapers from the same manufacturer the same paint as the tractor would be good.

I remember on Cat a Laplant hydraulic pump was low gpm & psi 500 & later Cats 44 pump was a 1000psi but Google not finding info . Paint to match fleet in pic Allis orange,IH red or Hi way yellow

Would anyone have knowledge of the different wheel hub sizes from American manufacturers ?

The ones on the scraper are a 10 stud fitment but the hub size is 8” as far as I can measure ( will get the wheel off next week )
We can’t find anything over here to match up with ( original wheels are fair rotted out )

Thanks
Chris
