Title: O - Ring Size for Hinson Clutch cover ?
Post by: Justin4141 on December 10, 2025, 01:45:37 AM

Was just wondering if you guys can help me out with the size of the o-ring for the inner Hinson clutch cover before I go to the hardware store an play a guessing game on the o-ring size…

Should be able to measure the ID of the case groove with a tape measure. If you have calipers, I would measure the depth of the groove. Target an oring cross section ~0.5mm larger. A good website to use is McMaster Carr. With ID and cross section you should be able to find a standard size that you can cross reference to your local hardware store.

Unfortunately I don't have a case readily available to measure.

Best regards
