9.1. General Maintenance
The tiltrotators exposed position leads to that it is easily subject to damage. Through regular inspection and
maintenance, possible damages can be detected, prevented and resolved in time. WIth regular maintenance
reliability and longevity is secured and the risk of damage is reduced. To avoid damages and to facilitate inspection
and maintenance the tiltrotator should be kept clean. It is important to note that inadequate maintenance may
jeopardize safety and can result in serious injury.
Note: When in contact with your supplier or Steelwrist regarding maintenance, service or spare parts it
is always good to have the serial number of your tiltrotator available. The serial number is found at the
beginning of this manual and on the machine plate that is mounted on the tilt rotator.
Warning: The person who shall carry out inspection, maintenance and service must have sufficient
knowledge for carrying out the work in question.
Caution: Hydraulic lines may be under pressure. Before maintenance work is started, make sure to release
hydraulic pressure.
Caution: When using spare parts, original Steelwrist spare parts should be used. Steelwrist is not
responsible for non-original spare parts and its impact on other parts of the product.
Daily and weekly inspection should be performed. Daily inspection means that supervision must be carried out
every day before work begins, while weekly supervision is meant to be carried out every 40 hours of operation.
Deficiencies found during the inspection must be corrected immediately. Contact Steelwrist or dealer for any
questions.
9.2. Grease and hydraulic oil
Tiltrotator is factory filled with a grease type EP2. Steelwrists recommendation is that you continue to use a
grease-type EP2 / NLGI 2 with base oil viscosity greater than 180 cSt at 40 degrees Celsius. If central lubrication
is installed please follow the lubrication system supplier's recommendations.
Before delivery the tiltrotator is tested with hydraulic oil as indicated in the beginning of the user's manual. Hydraulic
oils must be approved for use with O-rings of material NBR70.
9.3. Axial and radial play
The tiltrotator is designed so that a minimal play is possible in both axial and radial direction. This is necessary
because the friction between sliding surfaces generates heat and as this affects the various metals differently. The
tiltrotator otherwise risk to "pinch". After a certain time in operation, the gap will increase slightly as the tiltrotator is
run-in. Wear is influenced by high break out forces, general driving style but mainly neglected lubrication.
It is very important that you lubricate and clean the tiltrotator periodically. Hydraulic breakers can significantly
increases the wear so that tiltrotator over time may get an excessive play. It is important to monitor development
over time and ensure that neither the axial nor rotational play becomes too large. Play above what is specified
should be adjusted as soon as possible.
The delivery amount of axial and radial play is about 0.3-0.4 mm. Radial play is checked by the attachment coupler
being manually rotated relative to the gearbox. Mark a line on the gear box and attachment coupler. Then push the
attachment coupler manually to its end position (i.e. so that the screw tooth is pushed against the gear wheel and
the screw is against its sliding bushing inside the gearbox). This may be hard to do and maybe you need a crowbar
or similar. When the attachment coupler is in its end position should differ by less than 1.0 mm in the original marker.
If the play is bigger, bearings need to be replaced or shimmed.
Axial play are measured with a clock between attachment bracket and gearbox, so that the tool carrier manually
raised / lowered using a crowbar or similar. Also in this case, the play should not exceed 1.0 mm. If there is greater
play, the gearbox bearings may need to be replaced or shimmed.
After prolonged use it may be worthwhile to submit tiltrotator to your local service center or Steelwrist for full service
review. Normally, all wear parts such as slide bearings, bushings, grease, chafed hoses etc. are replaced. For
