Bosch A4VG A4VG 32 Series Instruction Manual page 31

After removal A dismounted axial piston unit must be stored 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
methods that are specifically designed for them. In such cases, consult
Bosch Rexroth Service, see Chapter 10.5 "Spare parts" on page 56 for
the address.
Bosch Rexroth recommends the following procedure:
1. Clean the axial piston unit, see Chapter 10.1 "Cleaning and care" on page 53.
2. Empty the axial piston unit.
3. For storage periods up to 12 months: Coat the inside of the axial piston unit with
mineral oil and fill with approx. 100 ml mineral oil.
For storage periods up to 24 months: Fill the axial piston unit with VCI 329
corrosion protection (20 ml).
Filling is done through the drain port T
piston unit", Fig. 15 to Fig. 17 on page 44.
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.
7. Store the axial piston unit in a non-explosive area in a manner that is shock-proof,
see "Requirements" on page 30 in this chapter.
