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
This should cover it.....
Thanks @Old Magnet thats a great help sir Chris
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
is it the rim ,or the centre that rusted out if the centre hub ,can make a new one out of steel plate
GI surplus wheels might be close .
It’s the rim that’s looking bad, and the locking ring too Chris
Would old truck rims work, TK Bedford's used a 10 stud rim on the later versions, don't know what the dimensions were though. If the stud pattern is the same the centre hole becomes an easy fix if it's different.
