HEQ5 Pro Belt Modification Kit
£95.00 inc. tax

£79.17 ex. tax
? Tax based on United Kingdom.


Dave Says: "This HEQ5 kit is quite easy to fit without fully dismantling the mount, and offers a noticeable improvement in slewing and tracking. We use it for the basis of our excellent StellarDrive™ 5, perhaps the sweetest tracking mount we do. The pinion extractor is a must, otherwise it will be an extra tenner for the swear box!"  

If you are looking to fully rebuild your mount, or it's over 4 years old then please consider either our of our tuned mounts at £399 or £549 including the kit. By the time you add up all the parts needed to match one of our mounts, it doesn't work out much more, and we replace/refurbish all the bearings and provide a 2 year RTB Warranty and PHD Guide Support. Also, our rebuilds will more than double the tracking accuracy of any home build mount.

HEQ5 Pro Belt Modification Kit 
(Kit only)

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 quieter
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.

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. 

An optional extractor tool is available to allow the pinion gear to be removed easily from the motor, and is strongly recommended.

Fitting instructions can be found here.

HEQ5 full stripdown and rebuild can be found here
