Transport and storage 39/104
RE 92076-01-B/10.2017, A4... with HS5E pilot control valve/Series 3x, Bosch Rexroth AG
A dismounted axial piston unit must be preserved with corrosion protection for
the duration of storage.
The following instructions only refer to axial piston units which are operated with
a mineral oil-based hydraulic fluid. Other hydraulic fluids require preservation
measures that are specifically designed for them. In such cases, consult Bosch Rexroth
Service, see Chapter10.5 “Spare parts” on page81 for the address.
Bosch Rexroth recommends the following procedure:
1. Clean the axial piston unit, see Chapter10.1 “Cleaning and care” on page79.
2. Empty the axial piston unit.
3. For storage times up to 12 months: Coat the inside of the axial piston unit with
mineral oil and fill with about 100 ml mineral oil.
For storage times up to 24 months: Fill the axial piston unit with corrosion
protection VCI329 (20ml).
Filling is carried out via the drain port, see chapter7.4 “Installing the axial piston
unit”, Fig. 16 on page51.
4. Plug all ports so they are airproof.
5. Moisten the unpainted areas of the axial piston unit with mineral oil or suitable,
easily removable corrosion protection, e.g. acid-free grease.
6. Package the axial piston unit with desiccant in corrosion protection film so it
is airproof.
Store the axial piston unit in a shock-proof manner, see “Requirements” on
page 38 in this chapter.
