1 Commissioning

1.1 Commissioning after an extended downtime

Before the transmission is commissioned again following an extended downtime, perform required measures (refer to section Corrosion protection and preservation, page 7).

Commissioning

4 EN 3000.765.104 - 2017-05

2 Storage

2.1 Preservation with ex works delivery

The volume production transmissions as supplied by ZF Friedrichshafen AG are equipped with corrosion protection according to preservation stage I or II (refer to tab. 1, page 5).

The preservation measures for long-term storage must be defined in the transmission order.

Preservation stage

Tab. 1 Preservation with ex works delivery

2.2 Preservation of marine transmissions during storage at the customer

After expiration of the corrosion protection, the corrosion protection has to be extended, in case of preservation stage I with preservation stage III and in case of preservation stage II with preservation stage IV (refer to tab. 2, page 6).

Storage

EN 3000.765.104 - 2017-05 5

This also applies if the transmission is stored at ZF representations or ZF vendors.

The preservation measures as described below may only be implemented by staff authorized by ZF, otherwise the warranty claim shall become void.

▪ Housing: finished coating or wash priming (on water basis)

▪ Transmission delivered in wooden box, not watertight.

This type of packaging is only adequate for indoor storage.

▪ Fill the transmission with the specified corrosion protection oil to the upper measuring mark of the oil dipstick.

▪ Immediately after having filled the corrosion protection oil, perform preservation run for at least 5 min at an engine speed of 500 rpm in enginewise rotation and counter-rotation shift position each.

▪ Check external preservation.

▪ Repair or replace damaged protective film with specified corrosion protection agent.

▪ Store in a closed room with few temperature fluctuations and low relative humidity.

▪ Protect against dirt and moisture in the period between installation in the ship and initial operation.

▪ Observe Shelf Life Extension.

PRF-21260E NATO

code C-640 or C-642 or

TL 9150-0037

according to BAAINBw

▪ Completely drain corrosion protection oil.

External preservation:

▪ Blank parts with corrosion protection agent corresponding to MIL-C-16173D Typ 4, K 19 or TL 8030-015, Typ 4 according to BAAINBw

New packaging according to preservation stage II (refer to tab. 1, page 5)

▪ Visually inspect transmission and replace aged parts.

▪ Store in a closed room with few temperature fluctuations and low relative humidity.

▪ Read moisture indicator before using the transmission and before the maximum storage period has expired. If the moisture indicator shows NOK, contact the local ZF service branch before the transmission is used.

▪ Protect against dirt and moisture in the period between installation in the ship and initial operation.

▪ Observe Warranty Reinstatement Policy.

3 Decommissioning

3.1 Corrosion protection and preservation

The corrosion protection measures required in the event of extended breaks in operation for a transmission installed in the ship depend on:

▪ Temperature fluctuations

▪ Atmospheric humidity

▪ Air salt content in the machine room

The recommended actions and time information therefore only represent rough reference values.

Property damage due to uncontrolled movement of the ship during preservation run possible.

ð Ensure sufficient free space around the ship.

ð Moor ship.

ð Mechanically separate output from transmission.

Decommissioning

EN 3000.765.104 - 2017-05 7

Preservation stage

Downtime period

Corrosion protection Implementation/Storage conditions

V Up to maximally 12 months

No special corrosion protection required. The transmission oil may remain in the transmission.

▪ Start the engine every 10 to 20 days and, for lubrication purposes, allow the transmission to run for at least 5 min at engine idle speed or at a slightly increased engine speed.

In doing so, the transmission can be in neutral, enginewise rotation or counter-rotation shift position.

▪ Prior to recommissioning, check the oil for condensate.

This test must take place immediately after switching off the engine. The oil may not be opaque.

▪ Adhere to oil change intervals (refer to Section Maintenance work 141: Changing the oil) in the corresponding operating instructions.

VI 12 months to maximally 36 months

Internal preservation:

▪ Corrosion protection oil according to MIL- PRF-21260E NATO code C-640 or C-642 or TL 9150-0037 according to BAAINBw

External preservation:

▪ Blank parts with corrosion protection agent corresponding to MIL-C-16173D Typ 4, K 19 or TL 8030-015, Typ 4 according to BAAINBw

▪ Housing: finished coating or wash priming (on water basis)

▪ Fill the transmission with the specified corrosion protection oil to the upper measuring mark of the oil dipstick.

▪ Immediately after having filled the corrosion protection oil and every 12 months, start the engine and let transmission run for at least 5 min at engine idle speed or at slightly increased engine speed in enginewise rotation and counter-rotation shift position each.

▪ Check external preservation.

▪ Repair or replace damaged protective film with specified corrosion protection agent.

▪ Protect against dirt and moisture.

▪ Prior to recommissioning, completely drain the corrosion protection oil and fill the transmission with the specified oil grade and oil quantity (refer to Section Maintenance work 141: Changing the oil) in the corresponding operating instructions.
