Description of Change: A new diverter valve has been designed in order to eliminate the drifting of the locking pin cylinder and the lift group cylinder.

Adaptable To: The 348-5223 Diverter Valve Gp is a direct replacement for the 162-7269 Control Valve Gp. The existing mounting bolts need to be replaced with longer bolts. The 7X-2539 Bolt replaces the 6V-5223 Bolt.
