The kit contains two standard 77mm ring sets, the complete gasket set (head, valve cover, intake and exhaust gaskets and small O-rings), two crankshaft oil seals and crankcase sealer. Pistons, rods and valves are not included. It fits the CH18, CH20, CH22, CH620, CH621, CH640, CH641, CV18, CV20, CV22, CV620 and CV640; some CH22, CH620 and CH640 engines are the 80mm, 674cc version, so check the displacement on the nameplate. Use it when the pistons are free of scoring and the ring grooves are not worn, and only on cylinders at the 77mm standard size. Before assembly, check each bore for taper and out of round, hone lightly for a crosshatch, and check the end gap of each ring in its bore.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRINGS, GASKETS, SEALS AND SEALER - Two standard 77mm ring sets, the complete gasket set with head and valve cover gaskets, two crankshaft seals and crankcase sealer.

Scored pistons or worn grooves need new pistons, not just rings.\u003c\/li\u003e\n\u003cli\u003eSTANDARD BORE ONLY - For cylinders at the 77mm standard size. A cylinder that has been bored needs oversize pistons and rings to match.\u003c\/li\u003e\n\u003cli\u003eCHECK THE BORE FIRST - Rings will not seal a scored, glazed or out-of-round bore. Measure taper and out of round, hone lightly for a crosshatch, and check the end gap of each ring in the bore it will run in.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lil Red Barn","offers":[{"title":"Default Title","offer_id":68009599336602,"sku":"J5-A8M0-ZEVB","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0397\/2346\/6909\/files\/713nw0_BoAL.jpg?v=1793382290","url":"https:\/\/performancesawsupply.com\/products\/77mm-ring-gasket-kit-fits-kohler-ch18-ch20-ch22-cv20-j5-a8m0-zevb","provider":"Performance Saw Supply","version":"1.0","type":"link"}
