Rowan Belt Mod HEQ5 help

[Simon Pepper]

Hi all it was Martins YouTube that I followed when making the backlash adjustments and if I had not done the mod as well probably would have been fine. However I definitely had binding that’s why the gear was so tight the belt was somehow tightening and slipping trying to move it. I have done the backlash again it’s a very fine line between removing it and getting binding I didn’t think the margin of error was so small! But that said it’s done no apparent backlash and the gear is smooth the belt is back on and it’s tracking and it’s silent! Thank you to all on this thread really helped nail down the issue. I guess the real test will be next clear night but pretty confident now.

If when you check it in real life there is still some backlash, you might need to adjust the end float of the worm gears. (This is the two rubber caps covering the end of the bearings). I had to make my own tool to adjust these, but you can use circlip pliers or something similar. Again, there is a risk of overtightening so you need to be careful.
