dealer. Allison transmissions require special PTO’s. Consult Warren or your PTO supplier for
information on these PTO’s.
All Warren 5
th
Wheels are equipped with air shift direct mount pumps with counter clockwise
(CCW) rotation unless otherwise specified. If this is not compatible with the truck, contact your
Warren dealer to see if Warren can accommodate your truck’s requirements. Ensure the pump
(CCW) and PTO rotation and connection are compatible.
You can order your 5

wheel without a pump and use your own. There are several ways that your
pump may be connected. Please contact Warren or your distributor if you have questions about
the correct way to hook up a non-standard pump. In all cases, you should use a 10 micron filter in
the system.
