put some silicone oil inside the cooling jacket! -
sometimes water will work also or some thin oil like sewing machine oil, 3-in-1 oil, etc. Start by trying to twist/turn the jacket. When it rotates easily, pull it off while turning. Reinstall it the same way. Don't use WD40. It will eventually eat up the rubber o-ring.Mini Cat Racing USA
