▪ Total mileage [km]
▪ Progress of the damage
▪ Damage pattern
To avoid personal injury and damage to third-party products and the ZF product, this safety information,
all valid safety regulations, and legal requirements must be observed.
Country-specific safety, accident prevention, and environmental regulations apply irrespective of the
information provided in this document.
Safety-relevant workwear must be worn for all work. Depending on the type of work, additional protective
equipment, e.g. protective goggles, protective gloves, hard hat, and apron must be used. The workwear
must fit tightly so that it cannot get caught in turning or protruding parts.
Safety Instructions
6EN 4472.751.001 - 2015-11

After completion of repair, assembly, and maintenance work, as well as inspections, the specialized staff
must ensure that the ZF product is once more functioning perfectly and is safe to operate.
The user/operator is responsible for assigning the corresponding section of the documentation to the
correct target group. The former must ensure that the corresponding section of the documentation is kept
in close proximity to the ZF product and remains accessible to the concerned target group.
Using ZF products
Impermissible superstructures, add-ons, modifications, and changes to the ZF product may affect the ZF
product's operational safety.
Unless explicitly permitted, no repair, assembly, and maintenance work may be performed while the
engine is running. Secure the engine against an unintentional start and the vehicle against unintentional
movements. Attach a "Do not operate" sign which is visible for everyone! Keep uninvolved parties away.
Prior to starting work, always secure the ZF product properly using suitable means. Do not work on ZF
products that are only held with lifting equipment or a crane. Risk of injury from tilting or falling parts
and/or tools.
▪ Do not walk under suspended loads.
▪ Keep distance.
Lifting and moving heavy parts without tools may lead to health damage or serious injury.
▪ Only use permitted means of transport, lifting tools with a sufficient load capacity, and suitable lifting
technology.
▪ Observe safety regulations.
Increased risk of injury in the event of contact with cooled down or heated parts. Only touch parts when
wearing suitable protective gloves.
Noise
Wear suitable ear protection at all workplaces with a sound pressure level above 85 dB(A). The country-
specific safety regulations and the accident prevention regulations apply irrespective of this. Noise can
lead to a higher risk of accidents if the noise affects the perception of acoustic signals, warning calls, or
other sounds alerting to danger.
Handling operating supplies and auxiliary materials
Increased risk of injury at contact with heated, cooled down, or caustic operating supplies and auxiliary
materials (e.g. lubricants, cleaning agents, nitrogen).
▪ Prevent skin contact.
▪ Do not drink.
▪ Do not inhale vapors.
▪ Keep away from ignition sources – do not smoke.
Store operating supplies and auxiliary materials in suitable and correctly labeled containers.
Use suitable protective clothing, protective gloves, and protective goggles/face protection.
Pay attention to the manufacturer's regulations and accident prevention regulations.
Safety Instructions
EN 4472.751.001 - 2015-11 7

Immediately seek medical assistance after contact with heated, cooled down, or caustic operating
supplies and auxiliary materials.
Environment
Operating supplies and auxiliary materials may not be allowed to enter the soil, groundwater, or sewage
system.
▪ Request material safety data sheets for the corresponding ZF products from your responsible
environmental protection authority, and observe them.
▪ Collect operating supplies and auxiliary materials in a sufficiently large container.
▪ Dispose of operating supplies and auxiliary materials, waste, containers, soaked cleaning cloths,
contaminated filters, etc. in accordance with the regulations of the environmental protection laws.
▪ Pay attention to the manufacturer's regulations and accident prevention regulations.
When selecting operating supplies and auxiliary materials, pay attention to health risks, environmental
compatibility, disposal regulations, and your country-specific opportunities to dispose of such materials
properly.

functioning perfectly and is safe to operate.
3.2 Cleaning the ZF product
Clean the ZF product with an appropriate cleaning agent prior to repair or assembly works.
Possible damage to ZF product due to water infiltration.
ðBe careful when using a pressure washer on the ZF product.
3.3 Dismantling the ZF product
▪ To avoid mixing up parts, the parts must be clearly assigned to the disassembled ZF product. In
particular, this applies to gear parts, reusable spacer washers or shims, electronic components, etc.
▪ Assemblies which must not be disassembled or are only available as spare parts assembly are
described accordingly. Please refer to the spare parts catalog for the ZF product.

Notes on Repairs and Assembly
10 EN 4472.751.001 - 2015-11

Sealing compound
Sealing compound is only to be used when described as such in the work step
(refer to section Operating
supplies and auxiliary materials)
. Please observe the manufacturer guidelines and processing instructions.
Apply the sealing compound thinly and evenly. Keep oil ducts and oil bores free of sealing compound.
When assembling the parts, no sealing compound must enter the oil ducts or oil bores.
Retaining agents
Retaining agents are only to be used when described as such in the work step
(refer to section Operating
supplies and auxiliary materials)
. Please observe the manufacturer guidelines and processing instructions.
Oil
Fill the ZF product with oil before operation. For the procedure and approved oil grades, refer to the
document valid for the ZF product, the type plate, and/or the latest List of Lubricants TE-ML. These
documents are available at all ZF Services Partner and here www.zf.com.
3.5 Cleaning parts
▪ Clean all reusable parts.
▪Remove sealing compound residue on sealing faces or retaining agent residue, e.g. in tapped holes or
on splines.
▪ Clean joining surfaces.
▪ Clean blind holes and blind hole threads.
▪ Lubricating bores, oil bores, oil ducts, bores for oil press fits, and lubricating grooves must be free from
dirt, preservative, and foreign matter. Check for free passage.
▪ Hose assemblies, tubes, and joining elements must be free from dirt, oil, and damage. Clean dirty or
oily parts. Check for free passage. Replace damaged parts.
▪ Clean all cavities and reliefs.
▪ Remove preservative from new parts.
3.6 Reusing parts
Authorized, specialized staff assess whether parts can be reused. Replace parts
▪if they are damaged
▪ if they are worn, e. g. bearings, multidisks, thrust washers, etc.
▪ if they have a permanent deformation
▪ if they have been overheated during operation or during disassembly.
Only replace with original ZF parts or ZF-approved parts. Please refer to the spare parts catalog for the ZF
product.
3.7 Replacing parts
The following parts must always be replaced:

▪Safety plates
▪ Shaft sealing rings
Only replace with original ZF parts or ZF-approved parts. Please refer to the spare parts catalog for the ZF
product.
3.8 Reworking parts
Authorized, specialized staff assess whether parts need to be reworked.
Minor damage on reusable components can be removed and reworked with suitable special tools if the
component's function is not impaired.
Minor damage includes:
▪ Indentation marks on sealing faces
▪ Score marks or burs caused by the disassembly of the ZF product
▪ Frictional corrosion
▪ Damage caused by paint or corrosion
If rework is needed on spacer washers or shims because of clearance settings, ensure that the reworked
surface is level with the starting face and has the same surface quality.
