Identify Mount Style
There are two styles of sequence valve mount:
• North American Models YP425/625/825 use a ground
drive mount, based on bundle:

This style mounts to the ground drive weldment using
existing planter fasteners and the smaller 7 mm
holes
in the side of the mount .
• Export Models YP625PD/TD and YP925 use a fan
mast mount based on bundle:
113-867S SEQUENCE VALVE MOUNT ASY FAN
This style mounts to the existing fan post using a new
U-bolt (
, not shown) through the large 11 mm
holes in the side of the mount .
Note: Leave protective plastic caps on ports until
instructed to remove them at later steps.
Note: See table on page 11 for sequence valve port
assignments.
