Voith Turbo 866 DTVVN-X Fluid Coupling
Voith Turbo 866 DTVVN-X Fluid Coupling — Serial 7562771 — As-Is
Description
Offered for sale is one Voith Turbo 866 DTVVN-X hydrodynamic fluid coupling, serial number 7562771. The coupling is secured in a dedicated wooden crate and is sold as a single assembly, as-is, where-is.
The model designation 866 DTVVN-X and serial number 7562771 are physically marked on the coupling. This physical evidence controls the listing identification. The buyer must still verify configuration-specific fitment and service requirements with Voith before purchase or installation.
Voith describes its dual-work-circuit DTVV fluid-coupling configurations as having two parallel-acting work circuits to increase power-transmission capability relative to a single-circuit coupling. Actual ratings, fill volume, operating fluid, protection configuration, hub/shaft details, and fitment are configuration-specific and must be verified by the buyer directly with Voith using the physical model marking and serial number.
Documented OEM Overhaul Order and Condition Disclosure
