An uninstalled axial piston unit must bepreserved with corrosion protection for
theduration ofstorage.
The following instructions only refer toaxial piston units operated with
hydraulicfluid onamineral oil basis.
BoschRexroth recommends thefollowing procedure:
1. Clean theaxial piston unit; see chapter10.1 "Cleaning and care" onpage55.
2. Drain theaxial piston unit.
3. For storage times up to12 months: Moisten theinside oftheaxial piston unit
with mineral oil and fill with approx. 100 ml mineral oil.
For storage times up to24months: Fill theaxial piston unit with VCI329
corrosion protection (20ml).
Filling is performed via the drain port T or R(L), see chapter7.4 "Installing
theaxial piston unit", Fig. 12 on page43.
4. Plug all ports so they are airtight.
5. Coat unpainted areas oftheaxial piston unit with mineral oil orsuitable, easily
removable corrosion protection, e.g. acid-free grease.
6. Package theaxial piston unit with desiccant incorrosion protection film soit
isairproof.
7. Store the axial piston unit in a non-explosive area and in such a manner that it is
protected against shocks; see "Requirement" on page 28 in this chapter.
