so who else is tired of their polini water pump pulley breaking/cracking every few weeks, or after a couple hard laps???
well treatland and others alike sell the pulley band/belt for $5 - $7 and change AND shipping for 1 freaking O ring (belt)
was reading on this forum here:
and they have some great alternatives. i took their advice and went to my local Ace hardware and got a large O ring for a water filtration system. it's slightly thicker and imo that's fine/better.
took it on a 5 min ride,, was fine. will report back with any issues but this 2 pack was $5 at my local ace, rather then $10 (after shipping) +/- for 1 !!
