After delivery The axial piston units are provided with corrosion protection packaging at the factory
(corrosion protection film).
Table 7 lists the maximum permissible storage times for an originally packed axial
piston unit as per data sheet 90312.
Table 7: Storage time with factory corrosion protection
Storage conditions
Closed, dry room, at an even
temperature between +5 °C and
+20 °C. Undamaged and sealed
corrosion protection film.
Warranty is void if the requirements and storage conditions are not observed or
after expiration of the maximum storage time (see Table 7).
Procedure after expiration of the maximum storage time:
1. Check the entire axial piston unit for damage and corrosion prior to installation.
2. Perform a test run to check the axial piston unit for proper function and leak-
tightness.
3. If the storage time exceeds 24 months, the shaft seal must be replaced.
After expiration of the maximum storage time, we recommend that you have the
axial piston unit inspected by your Bosch Rexroth service partner.
In the event of questions regarding repair and spare parts, contact your responsible
Bosch Rexroth service partner or the service department of the manufacturer's plant
for the axial piston unit, see chapter 10.4 "Repair" on page 54.
After removal
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 chapter 10.4 "Repair" on page 54 for the address.
Bosch Rexroth recommends the following procedure:
1.
Clean the axial piston unit, see chapter 10.1 "Validity of the documentation" on
page 49.
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 about 100 ml mineral oil.
For storage periods up to 24 months: Fill the axial piston unit with corrosion
protection VCI 329 (20 ml).
Filling is performed via the drain port T or R(l), see chapter 7.4 "Validity of the
documentation", Fig. 12 on page 39.
4. Plug all ports so they are airproof.
