Kick Ass 47 Posted April 19, 2023 Share Posted April 19, 2023 Is there anyone on here that could help with the diameter of the crank on a yanmar 3gm30f for the front and rear man seals? Am wanting to get some speedy sleeves to fixe oil leaks but need the diameter to order the correct sleeves? Any help would be appreciated Quote Link to post Share on other sites

LBD 128 Posted April 20, 2023 Share Posted April 20, 2023 The sizes I have needed for repairs have always been in stock at "Bearing Supplies" so to avoid sizing errors, I dismantle, clean and inspect, measure myself and then go pick up the correct sleeves I need for the job. And sometimes it is not only diameter but sleeve length that needs to be considered, I like to eyeball the repair before committing $. Good luck with that rotten job.
