11 MAINTENANCE
The Vortek Loft Block has sealed bearings and usually needs minimal maintenance but the mounting
hardware should be checked and a few other simple inspections will suffice.
1. Check for proper torque on the beam clamp bolt and nut. This should be
17-20 ft/lb of torque using a torque wrench to confirm.
2. There are ‘Circlips’ on both sides of the 2 axles on the loft block. Check to make
certain that the clips are seated in the groove on the axle.
3. Look to see that all of the plastic covers are snapped into place.
4. The loft block should be free to swing in both a side to side motion and up/down
to a small extent.
LOFT BLOCK MAINTENANCE
TURNBUCKLE MAINTENANCE
Turnbuckle maintenance requires checking the locknuts to make
sure they are tight to prevent the turnbuckle from loosening or, if
your turnbuckles do not have locknuts then make sure that they
are moused.
Also check to assure that the cable drops are plumb and
not angled. The hanger bracket that is attached to the A-14
Aluminum Batten and the turnbuckle also should not be bent.
