Video: John Deere 4440 SCV rebuild.
After attempting the first SCV with no luck I called John Deere for some advice and decide to take it in.
The initial bill was over $2000 and I thought was totally out to lunch as you need about $400 in parts and a few hours labour. Armed with two days of research and 4 new valves I attempted the second SCV myself to see how long it would actually take and after 20-30 extra minutes trying to smooth out where the valve seats we had success. about 2.5 hours from removal to install and we had a function SCV.
HAS JOHN DEERE LOST TOUCH WITH THIER BILLING PRACTICES?
