It's been many years since I sat behind a JD dealer service managers desk. Will you PLEASE refresh my memory on how the return oil from a ""RH scv"" on a 4020/4430 gets routed to the hyd filter?? Thanks,Jim

Isn't there something in the operator's manual about that right scv and high flow loads? And some have a valve to turn in the scv for equipment with single acting rams? So oil returns to the trans sump with minimal back pressure? What ever the case, that oil return from the vacuum motor needs to be routed into that rockshaft return line. The proper port in a power beyond block. Or into a ported filter cover.

That statement about high flow loads isn't in my 4255 operators manual. OK according to you JD engineers put that sump oil return outlet in the parts catalog for no good reason. Evidently you didn't read/comprehend Mike Aylward's post.

I completely missed Mike's post about the small low flow planters. Yes the direct return to sump will reduce fam motor seal pressure on old simple cheap motors.And the trans pump will keep up. Now getting back to the hydrualic flow that a 12 row planter requires.............

I thought that a 12 row was what we were discussing. At least the photo schematic of the hyd sump connection came out of a 1760 parts catalog.
