HE2000 Series Concentric AB BARNES Tube Kit. Steel. FO

The HE2000 series units are called out as using the same adapter size across the line, so this tube kit is intended to match that common HE2000 adapter size.

Premium grade petroleum based fluids are the recommended choice. Optimum operating viscosity sits right between 80 and 288 SSU, though the system can handle a cold start viscosity up to 9000 SSU if needed.

For HE2000 Series work, these kits are intended both ways. They can be used to repair or modify existing HE2000 Series power units, and they can also be used when you are putting together a custom HE2000 Series power unit.

These kits can be used to repair or modify existing HE2000 Series power units, or to build custom ones, so yes. The Model Code is a useful tool for kit selection for custom units.

Most premium grade petroleum-based hydraulic fluids work fine in these units. The optimum viscosity range runs 80 to 288 SSU, though the system can handle down to 66 SSU on the low end and up to 3600 SSU on the high end. Cold starts are permissible up to 9000 SSU. Standard premium hydraulic oil typically falls well within that range, so you should be in good shape as long as you're not running something off-spec or heavily contaminated. Keeping cleanliness at ISO 4406 level 18/14 or better is also recommended to protect the gear pumps and valves over time.
