Hose Crimping Assembly / Inspection

Guidance for Hose Crimping Assembly/Inspection

Approved hose crimping assembly and inspection instructions outline inspection requirements and checks for hose and fitting assemblies in line with Ryco Hydraulics specifications.

1. Purpose

To ensure hose assemblies are consistently assembled and inspected in the correct manner and comply with order requirements.

2. Scope

This procedure applies to all approved hose assembly personnel who are required to use crimping machinery to manufacture and inspect hose assemblies.

3.0 Procedure

3.1  Check the required crimp diameter using the Ryco Crimp App.

3.2 Ensure the correct set of crimp jaws is installed in the crimp machine to achieve the required crimp diameter.

3.3 Assemble the coupling to the hose as per the relevant Ryco procedure or applicable document ensuring that the correct coupling insertion length is clearly marked on the hose cover prior to inserting the coupling.

3.4 Set the crimper to the required setting to achieve correct crimp diameter.

3.5 Place hose coupling assembly inside the crimper and crimp coupling. Refer to Document No. RH-WI-101. Immediately visually check the coupling insertion depth mark and measure the crimped diameter with a calibrated vernier caliper. If the diameter is not correct, then adjust the crimp setting as required, align the crimp jaw marks in the crimper and repeat the procedure until the crimped diameter is correct.

3.6 Visually inspect outer cover and inner tube of hose for any damage or obstruction.

3.7 When the crimper is correctly set up, commence production. Check every crimp dimension and coupling insertion depth mark on the first 5 off hose assemblies, and then check 1 in every 50 thereafter.

3.8 NOTE: The first 5 off completed hose assemblies MUST also have every crimp diameter and coupling insertion depth mark and hose configuration detail checked by another authorised hose assembler / inspector. The checker and crimp operator shall sign and date the picking slip (or the relevant inspection sheet) confirming all is correct.
