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 a case,
consult with your local contact person, you can find the address under

Bosch Rexroth recommends the following procedure:
1. Clean the axial piston unit, see chapter 10.1 “Cleaning and care” on page 51.
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 VCI329 (20ml).
Filling is done through the drain port T
1
or T
2
, see chapter7.4 “Installing the axial
piston unit”, Fig. 13 to Fig. 14 on page41.
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 shock-proof manner, see “Requirements” on page
27 in this chapter.
