Introduction
This Special Instruction provides the necessary procedure for installing a single-shank ripper (1PH) and mechanical or hydraulic pin puller on a D9N Tractor. Installation of a multishank ripper (1NH) is similar.
NOTE: Each section contains the related parts list.
After the assembly is complete, prepare the machine for service as shown in the machine's Operation & Maintenance Manual.
Do not perform any procedure, outlined in this publication, or order any parts until you read and understand the information contained within.
Reference: Service Manual, Parts Manual and Operation & Maintenance Manual.
