Handy Don 10,439 #3 Posted September 16, 2022 Bumping this old thread for an update on the S/G Starter Generator Belt for K-181. I tried using a Napa 25-7315 belt (31.5" x .41") on my K-181 and it was too short, leaving the S/G practically up against the engine cooling tins. Instead used a NAPA equivalent 25-7320 from D&D Power Drive which went on easily and left the S/G adjuster right in the middle of the range when properly tensioned. 1 Share this post Link to post Share on other sites
