Portable hydraulic unit
Description
246-9977-00 portable hydraulic unit
The 246-9977-00 is a compact portable hydraulic unit used to check aircraft hydraulic circuits on the ground when the main engines are not running. A specialist product catalog also records the newer designation NVKV.062848.001 for this type. The unit is housed in a transportable protective case and is intended for maintenance work rather than installation aboard the aircraft.
Available documentation describes a service reservoir, pump, fine filter, pressure indication, connecting hoses and quick-release interfaces arranged within the cabinet. The equipment is connected to the aircraft hydraulic servicing panel and allows the relevant systems to be checked in sequence. This is more precise than the former generic description and avoids assigning unsupported pressure or flow figures.

Hydraulic servicing role and aircraft application
Ground-support lists place 246-9977-00 in the Mi-8 and Mi-17 maintenance equipment family. A separate specialist GSE source describes the same compact 28 V DC unit for the Mi-24 and L-39 when servicing a single-pressure hydraulic system. Because aircraft modification and ground connections can differ, the intended aircraft and the approved task card must still be confirmed before use.
The unit can receive electrical power from an approved ground or onboard source according to the maintenance procedure. Its purpose is functional checking, not permanent hydraulic supply in flight. Operators should confirm the electrical connector, hose ends, service fluid, pressure setting and required adapters against the aircraft documentation before connecting the equipment.
Aircraft-family reference: Mil Mi-8. This external reference does not replace the approved maintenance manual.
Identification and inspection before use
Ordering should be based on the complete 246-9977-00 designation, with NVKV.062848.001 recorded as a documented alternative reference. Punctuation variants such as 246.9977.00 are useful for search, but they do not create a different approved configuration. A visually similar portable hydraulic cabinet must not be accepted solely because its color or layout appears comparable.
Before operation, maintenance personnel should inspect the cabinet, reservoir, pump, filter, gauge, cables, hoses, couplings, seals and protective caps. The working fluid, cleanliness requirements and connection sequence belong to the aircraft procedure. Actual calibration, operating limits and delivery completeness must be established from the supplied records rather than copied from another hydraulic unit.
Supply of the 246-9977-00
This product card records Condition: New, Warranty: 6 Months and YOM: 2026. The existing catalog price and Pre-Order status are retained without alteration. The stated 90–120 day lead time is an estimate and should be reconfirmed together with the required passport, test record, hose set and connection accessories when a quotation is prepared.
For an accurate request, provide the aircraft type, hydraulic-system version, intended maintenance operation, destination and quantity. Related Ground Support Equipment items shown on this page are offered for navigation within the same maintenance category; they are not interchangeable with 246-9977-00 and may perform completely different tasks.
