HEQ5 Pro & Orion Sirius Belt Kit.
HEQ5 Belt Kit.

This kit replaces the factory spur gear drive train with timing belts.
The pulley modification reduces the spur gear errors that are typical and
therefore reduces tracking errors. The belts also make slewing much quiter
eliminating the 'grinding' noise that the standard spur gears produce.

The pulley ratio is the same as the factory gears. This means the
Synscan hand controller is unaffected by this upgrade. All Synscan
functions will operate as before.

HEQ5 Belt Kit.
The kit comprises of -
2 x 47 tooth pulleys. 2 x 9 tooth pulleys.
2 x timing belts.
2 x intermediate rollers. 2 x 5mm mounting shafts.
1x 8mm white acrylic cover spacer + 6 stainless fixings.
