Caterpillar Products: AllIntroduction
The following information explains the repair/assembly process for hydraulic hoses through the hose service shop. The steps follow the Caterpillar recommended best practices. Every service shop is different, but the basic workflow and process still applies to all. It is a management decision at the dealership as to what extent they follow the process. The dealer can use the Service Operation Development and Assessment (SODA), SERF8918 to access their level of compliance. The compact disc can be ordered through the media logistics system. After the assessment is completed, a plan can be developed based on the findings. Service Operation Development and Assessment (SODA), SERF8918 will help identify process and tooling gaps in operations. This document also references other supporting documents that cover the various stages of the hose repair in detail.References

Customer brings in a hose to a clearly marked hose shop.
The work order is written.
Parts availability is verified.
New hose is cut to the correct length.
Clean the hose.
Skive the hose.
Reclaim the old couplings if needed for the new hose assembly.
Install first coupling on the new hose.
Crimp the first coupling onto the hose.
Install armor guarding if necessary.
Set the angle of orientation of the new couplings.
Crimp the second coupling onto the hose.
Deburr the couplings if necessary.
Clean the final assembly.
Recheck the assembly for the correct angle of orientation and overall assembly length.
Install caps or plus on the couplings.
Attach the bag containing seals to the hose assembly.
Apply the appropriate stickers to the finished assembly.
Apply the metal assembly part number band.
Present the final assembly to the customer or store the assembly on a shelf for the customer to pickup.Parts Counter / Receiving Area
The first thing the customer should see is signage off of the frontage road. The sign should indicate hydraulic hose shop. Marketing literature for promoting Caterpillar hose and couplings should be on the parts counter for the customer to read. The customer should be greeted by the counterperson or hose assembler who will fill out
