UTRK-40 Assembly Instructions

If there is access to a flat surface (garage / shop floor, saw horses with plywood, etc.),
Method 2 makes the alignment / installation of the modules quite a bit easier. The completed
sub-assembly can then be lifted on to the pole and tightened in place.
Method #1
Attaching Gimbal to Pole
• Place Gimbal on top of pole.
• Orient Gimbal so that the welded channel “leans”
towards true south (adjust for magnetic declination).
• Tighten bolts to 60 ft-lbs torque in turns to insure both
are tight.
Installing Axle
• Install bolts in the order shown.
• For purposes of installation, tilt the axle in
the shallowest position.
• Bolts only need to be lightly tightened for
rack assembly.
• After assembly is completed, tighten the
5/8” bolt to 75 ft-lbs, and the 1/2” seasonal
adjustment bolt to 30 ft-lbs.
Inner Axle
• Install Inner Axle and tighten 3/8” bolts
enough to keep it in place.
• The position of the Inner Axle will need to
be adjusted when installing modules.
Installing Bearings
• Install bearings as shown. Note the mounting
side of the bearings faces outwards.
• While holding the square welded nuts with
either a 1” open-end wrench or adjustable
wrench, tighten 5/8” bolts to approximately 40-
50 ft-lbs.
• The bearings are designed to swivel and may
not look “square” with respect to the axle.
