No-Skive couplingThe XN No Skive couplings are the next generation of couplings that have been developed by Caterpillar. The couplings are aimed at replacing the reusable couplings and permanent couplings. Caterpillar is introducing No-Skive couplings for only Dash 6 and Dash 8 XT hoses. No-Skive couplings for Dash 10 through Dash 32XT hoses will be phased in over the next couple years.

Benefits
The XT No-Skive couplings provide several benefits. Dealer inventory, storage space and inventory costs are significantly reduced because each No-Skive coupling satisfies the coupling requirements for XT-3, XT-5, XT-6 ES and ToughGuard hoses. For example, some Dash 6 and Dash 8 No-Skive couplings replace as many as five couplings each. Additionally, as the name implies, the No-Skive couplings eliminate the need for the hose to be skived prior to assembly. This not only reduces labor and assembly time, it reduces the chance for installation error and system contamination from rubber particlesIdentification

The label also includes the coupling crimp diameter in millimeters, symbols identifying hose type compatibility (ê = XT-3, + = XT-5), (XT-6) (C) .Crimp Diameter
Diameters of crimp are listed below. The diameters of crimp will also be located on the sticker that is attached to each coupling that will be received through parts inventory. To ensure a proper diameter of crimp, measure the diameter of crimp halfway up the coupling. Take four measurements on the coupling. Next, average the four measurements and compare the measurements to the Diameters Chart.

The latest version of software that is listed in this Special Instruction needs to be installed. Communicate the change to any stores, customer sites, and second-level distributors. These couplings use existing Caterpillar tooling and hose assemblies. No special tooling is required.Use the NEEG3000 crimp chart for the 209-3153 Hose As Machine (Portable) and the 209-3153 Hose As Machine (Bench Model II) that are equipped with variable die bowls. You will need the smooth bore dies. The 139-5439 Hose As Machine , 145-3381 Hose As Machine , 150-2568 Hose As Machine (XT), 173-9805 Hose As Machine (XT) and 4C-9900 Hose As Machine (XT) can also be adapted for use with variable die bowl and smooth bore dies. Refer to Table 2 for the Crimputer, Crimputer II, and Radial crimpers reference numbers.
