Usage:
637E ( 1JB1-568)
Introduction
A new 8W7810 Hose Assembly, clips and a plate are now available from the Parts Department as a replacement for the existing hose on the steering lines group on 631E and 637E tractors.
The new hose assembly is attached to the outlet side of the steering oil filter. The plate and clips are used to support the hose assembly above the transmission.
Formerly, the hose assembly could rub against the transmission which shortened the service life of the hose assembly.
