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 :-)
An optional extractor tool is available to easily remove the pinion gear from the motor.
Please note: Some older HEQ5 Pro mounts (around 5+ years) are not compatible with the Rowan Upgrade kit.

Speedy delivery from FLO, fitted the belt mod to my heq5 pro mount, sounds like a totally different mount, havenít tried it outside yet due to the weather, also purchased the pinion extractor tool which is a must, a great upgrade well worth the money.

Straight forward to install (get the additional pinion extractor), instructions a easy to follow. My mount is a lot quieter after fitting , not had chance to see if my guiding has improved due to bad weather

The package arrived within 5 working days in SW France, no charges from La Poste (yet?). The upgrade is well made and the instructions very good...especially when you have watched several videos on the subject! Fitting would have been very easy but for some poor quality control on the mount's motors (holes not round) but easily sorted. The distances suggested were also out due to said Skywatcher inconsistencies but again I just made sure everything was level and running smoothly. Oh the lack of grinding noises and backlash. My guiding has also improved considerably. Value..seems expensive but I would prefer to upgrade this mount than spend 10x to 20x (or more) on a new mount. Add this upgrade to the ADM dual saddle (also from FLO), improved azimuth bolts and mounting on a pier and I should be OK. One other thing...buy the pinion extractor (4mm in my case)

Once again, super quick delivery and quality products. The belt mod especially is a quality product that has really improved the mount accuracy. Very happy
Fantastic service from FLO

I have not long fitted the belt mod to my HEQ5 Pro and tested it on an imaging session over the weekend.
Prior to fitting the belt mod I was achieving circa 1.3" RMS error however the other night I was averaging around 0.8" - baring in mind that there was a 'breeze' in the air I thought that was a huge improvement.
Thanks to FLO for the well packaged, quickly sent item. A fantastic service as always!
Sky-Watcher heq5 pro belt mod

Good quality, easily fitted with included instructions. Flo delivered promptly. Just need the clouds to go away so I can see if it improved the sky watcher mount. I have high hopes as when I stripped the original gears away from the Mount I could visually see the backlash in the gears as I rocked them back and forward.

The the pinion extractor is an essential, but if you follow the instructions and are methodical then itís 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 itís easy enough if you do have one.
Awesome improvement for Sirius EQ-G

The belt kit from Rowan astronomy came well packaged and labeled!
The instructions were clear and thorough with detailed pictures to clarify the text.
The mount is much much quieter. The sound with the old gear train (before the timing belt upgrade) was annoying.
The 4mm gear extractor made easy work of removing the small drive gear from each motor.
I have only recently performed this upgrade and have not had much time at this scope since. But everything I
have read on the Rowan upgrade has been positive. I expect the same.
By the way, Martin at FLO was quick to answer some questions and they also had the best price.

Very easy to install, manual is easy to follow plus there are tons of videos out there.
The slew is more quiet now, PHD tracking is way better - it's like a different mount
The Pinion Extractor should be included in this kit.
