Summary

This tooling has been developed to support the assembly and disassembly of Positive Pin Retention (PPR) & Positive Pin Retention 2 (PPR2) track. The improved extruder assembly has been designed to have a quick twist and lock mechanism. There will now be only one base that is common to every model of PPR & PPR2 track. Each specific model of track machine will have 1 original face that can be used with the common base. Both face and base assemblies can be used for the shop track press, 150 ton 2 bar press and 150 ton 4 bar press.

Note: All previous threaded extruder groups used for PPR and PPR2 track will be replaced by the improved extruder assembly.

Safety

Illustration 1	g02139237

Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools in order to perform these functions properly.

This bulletin may contain hazardous steps. A safety alert symbol like the one below is used to identify to a hazard.

Warning messages identify a specific, imminent, latent, hazard that has a reasonable probability of resulting in personal injury or death if the warning is ignored.

Show/hide table

Do not attempt to disassemble or assemble this machine until you read and understand the disassembly and assembly instructions. Improper disassembly and assembly procedures could result in injury or death.

Show/hide table

Do not stand near the hydraulic press while the press is in operation. A component that slips or breaks under pressure may fly into the air with great force. Personal injury or death can occur if struck by flying objects.

Canceled Part Numbers and Replaced Part Numbers

This document does not include all canceled part number and replaced part number information. Use NPR on SIS for information about canceled part numbers and replaced part numbers. NPR will provide the current part numbers for replaced parts.
