Rowan Astronomy Belt Mod Kit

Take your HEQ5 Pro to the next level

This kit replaces the HEQ5 Pro’s spur gear drive train with timing belts.

Reduces spur gear errors, which reduces tracking errors.

Slewing is much quieter – the ‘grinding’ noise that regular spur gears produce is significantly reduced.

The pulley ratio is the same as the factory gears so Sky Watcher SynScan hand controller functions are unaffected. All gain and no loss 🙂

HEQ5 Belt 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.

Rowan HEQ5 Belt Kit Fitting Instructions

An optional extractor tool is available (CLICK!) to easily remove the pinion gear from the motor.  (4mm version here)

Please note: Some older HEQ5 Pro mounts (around 6+ years) require an additional step when installing this upgrade kit.

“The the pinion extractor is an essential, but if you follow the instructions and are methodical then it’s pretty straight forward. One of the instructions is to set a pulley 5.5mm away from the body so you may struggle without a digital vernier calliper but it’s easy enough if you do have one.” – Dan
