hydraulics

Hi everybody and happy holidays! I have a new project , am installing a Thumb to my 420-C loader and am looking for advice as to hose assemblies and if the 420 HYD pump will handle such an addition. Any help is much appreciated, IMO, this is the place for just that 8)

420 c loss of power

Howdy Dusty, you might want to check your distributor, make sure it is advancing the timing properly, this can effect the engine power making it seem like the brakes have been applied. Of course what do I know I own a '56 420-l-c too :roll:

You...
