Subject: PP-3 Tractor Protection Valve
Reference: Catalog Page 03-L-2
In 1976, the PP-3 upper body was revised from piece number 240381 to 290674. This
change eliminated the auxiliary delivery port.
Reports from the field indicate the auxiliary delivery port was being utilized by some O.E.
manufacturers, and the current service replacement valves 288746 (button equipped)
and 279787 (remote mount) could not be used for service replacement.
In response to this need, we have made available PP-3 service replacement valves
incorporating the auxiliary delivery port. Piece numbers are:
289477 (for button equipped valves)
289512 (for remote mount)
