Rowan belt mod genius'

[AstroBogan]

I require assistance from those who have belt modded their HEQ5 pros with the rowan belt mod.

With the pinion extractor, I haven't had the chance to open my mount up but want to order this mod now. What size pinion extractor would work with the HEQ5 pro?

cheers.

I did my one earlier this year, you need to open your mount and see if you need a 3mm or 4mm pinion extractor.
My mount was 3mm but you need to check it by removing the side cover and measuring the pinion.
