Description
JCB PD70 Series Axles Service Manual is the factory technical publication for the maintenance, dismantling, assembly and adjustment of PD70 series axle and brake systems. Issued by JCB Drivetrain Systems Ltd under publication number 9803/9100, this 108-page manual is identified as Issue 7.
This publication is intended for workshop engineers, axle rebuilders and experienced service technicians. It provides technical data, service-tool information, routine maintenance instructions and illustrated procedures for major axle assemblies. The manual also covers relevant brake arrangements and optional equipment associated with the PD70 axle family.
The instructions use “Forward” and “Reverse” on the basis of a front-mounted engine. As PD70 axles were produced with different gear, brake and differential arrangements, technicians should establish the axle build identification before beginning repair work.
