Slight pulley and face b wear.

Hello,
I am not sure if this has been posted ...looked around this site and if I missed it .... It happens.
I found a two grooves in the variators plates , I assume it's the lower at take off and the upper of cruising speed where the belt lives to spend most of the time..... I have 21 000 km on it and thought I should get triple that before replacing the variators for some $400 plus ,cost..... Can I take 2000 grid sandpaper to clean the glaze and work the wear area or is this to scientifically minded.(ha) .... I mean if I have to replace it any way why not.....has anyone attempted this already ..... Don't really want to spend 15g like my car which runs just as good as they I bought it....... Happy trails

It's odd you have noticeable wear at such low mileage, SW600 pulleys are very robust, yes, you can sand pulley faces, as is often recommended to sand pulleys lightly when installing a new belt, some do it to extend life or save $$, depending on the damage/ridges you can start with medium sandpaper 180-220 grit and finish with red then green scotchbrite, do it dry. You don't want the surface too smooth/slippery.

The most important thing is to use a sanding block (or anything flat) to back up the abrasive, not bare hands (they are not flat), try to do evenly and in a random pattern.

 I don't know the currency conversion to BC, shipping, Taxes, etc., but I got all 4, front and rear pulleys (to squirrel away), I paid approx. $250 USD with free shipping at Ron Ayers

My experience---with over 400,000 miles with rubber band drive scooters----put it back together and ride it...Monkeying can cause problem you do not need.

Thanks to the both of you , I'll do a cleaning and put it back together ....ride this afternoon and let it be......I never did get any vibration or strange sounds.......... Happy trails
