Foreword
This booklet will provide you with information on correct installation of Chelsea
®
Power Take-Offs (PTOs). Proper
installation and set up procedures will help you get additional and more profitable miles from your truck equipment
and components.
It is important that you be sure that you are getting the right transmission/PTO combination when you order a
new truck. An inadequate transmission will overwork any PTO in a short period of time. In addition, a mismatched
transmission and PTO combination can result in unsatisfactory performance of your auxiliary power system from
the start.
If you have questions regarding correct PTO and transmission combination, please contact your local
Chelsea
®
Auxiliary Power Specialist. They can help you select the properly matched components to ensure correct
and efficient applications.
