SCOPE
This service manual contains the installation, operating, lubrication and maintenance
instructions relative to the Hansen P4 standardized gear units.
Additional information can be obtained by contacting one of the HANSEN sales centres
worldwide (page 24).
All handling, storage, installation, start-up, inspection and maintenance of
the equipment shall be done by personnel qualified in matters of industrial
mechanical and - where applicable - electrical equipment.
1. GENERAL
1.1. GENERAL INSTRUCTIONS
Carefully read this manual before installing the gear unit.
Compliance with the instructions will assure long and troublefree operation of the gear unit.
The equipment should be checked against shipping papers and inspected for apparent damage
sustained during transport. Any shortage, discrepancy or damage must immediately be reported
to HANSEN.
1.1.1. Warranty
The warranty clause of the "General Conditions of Sale" applies to gear units installed and
maintained as per instructions contained in this manual and in any additional instruction leaflets
supplied with the gear unit insofar as the gear unit operates within the service and rating
conditions put forward in the "Order Acknowledgement" and on the certified drawings.
Non compliance with these instructions, injudicious choice of lubricant or a lack of maintenance
will render warranty agreement invalid.
This warranty clause applies to all parts of the gear unit with the exception of these parts which
are subject to wear.
1.1.2. Safety
It is not allowed to use the gear unit for other applications or in other
operating conditions than the one for which it is ordered.
The user shall be responsible for the proper installation of the complete
equipment and the supply of protection guards and other safety equipment in
accordance with local safety regulations.
Heaters, coolers, electrical alarms and other safety or monitoring devices supplied by HANSEN
with the equipment must be installed and connected by the user as indicated on the relative
document.
1.2. GENERAL SPECIFICATIONS
For general specifications such as dimensions, weight, connecting diagrams, refer to certified
drawing of the gear unit and/or to the Hansen P4 standardized gear unit catalogues.

1.3. IDENTIFICATION
Inquiries concerning a gear unit should always specify the unit's complete type code and
manufacturing number, which can be found on the nameplate. The nameplate, which is fitted on
each gear unit, also contains ratings and/or torque, speed and lubrication instructions. This
information is essential to identify positively the unit supplied by HANSEN.
2. SHIPPING
Prior to shipment each unit has been inspected and accepted by the QUALITY CONTROL
DEPARTMENT according to order specifications, and after no load test of several hours in its
normal operating position and at speed indicated on the nameplate.
2.1. SHIPPING CONDITIONS
Unless otherwise specified, gear units are shipped in unpacked condition and depending on
necessity, fixed on wooden pallets with open crating protection. Sometimes parts, such as spare
filter elements, are separately packed. In such events, the end-user must take care of the
assembly (see chapter 5. INSTALLATION p. 5).
The HANSEN P4 gear unit is shipped without oil.
All grease lubrication points are factory filled.
2.2. PAINTING
The standard external paint for HANSEN gear units is an epoxy primer with high solids content,
corresponding to the German Standard RAL 5021, water blue.
This paint system offers a 5 year protection for indoor installation provided the gear unit is not
subjected to humid or chemical aggressive atmospheric conditions.
Overcoating is possible with most paints based on alkyd-, epoxy or polyurethane resins.
2.3. PRESERVATION
The inner parts of the gear units are sprayed with rust preventing mineral oil. The breather plug
(standard, dust-proof, anti-humidity) is neither removed nor sealed.
The shaft extensions are protected with rust preventing grease and waxed paraffin paper. The
hollow shafts and all unpainted machined surfaces are coated with an anti-oxidizing waxy
varnish.
This standard system offers corrosion protection during transport and/or storage for up to one
year indoors.
3. STORAGE
Always store gear units in their originally supplied shipping conditions.
Gear units should not be stored near vibrating machines in order to avoid
damage to bearings.
3.1. SHORT TERM STORAGE
Up to one year indoors. Always store units in their originally supplied shipping conditions.

55
-5-
3.2. LONG TERM STORAGE
Max. 5 years indoors or 6 months outdoors.
•The protection should be kept intact if long term storage was specified at order
placement.
•In all other cases the gear unit must be filled with a small amount of mineral oil
containing a volatile corrosion protection additive. All gear unit openings (dipstick,
breather etc.) should be hermetically sealed.
Some additives may be added to the normal oil. Consult your oil supplier.
4. HANDLING
The Hansen P4 gear units are easy to handle and to install. Make use of integral oval lifting
eyes (horizontal mount) and lifting eye nuts or integral rods (vertical mount).
For equal load sharing make use of all lifting eyes and use adequate tools.
Lifting eye nuts must not be removed and must be fully engaged before
lifting.
Never lift units with slings wrapped around the shafts.
Particular circumstances might dictate the temporary removal of thermostat(s), pressure
gauge(s) and/or part of the oil feed piping. After removal of the latter elements, one should take
special care to avoid ingress of moisture, etc... into the lubrication system of subject gear
unit(s).
5. INSTALLATION
5.1. FITTING OF ACCESSORIES
The metric shaft extensions are equipped with keyways according to ISO/R773-1969 and DIN
6885 "Blatt 1 - Form N1 or N3".
Threaded centre holes in these shafts according to DIN 332 Teil 2 Form D.
Recommended bore tolerance for the couplings or other components to be mounted is K7 (as
per ISO 286).
The inch shaft extensions are equipped with keyways according to USAS B17.1-1967.
Recommended bore tolerance:
- 0.0005" to - 0.001" for diameters £1 1/2"
- 0.001" to - 0.002" for diameters > 1 1/2"
Remove protection from shaft extensions and check keyfit and keyway height in component to
be mounted onto shaft. Heating the component to 80-100°C (175-210°F) will be helpful.
Threaded centre hole in shaft to assist in mounting components onto shaft may be used.
Never mount components by impact as this may cause damage to the
bearings.
Never use rigid couplings except on free end machine shafts (e.g. mixers, aerators) or in
executions with a torque arm.
