2 Ring Sets Gaskets Fits Kohler 83mm CH25 CH730 1.2mm

A ring and gasket kit for the Kohler 83mm twin-cylinder engines, 725cc and 747cc. The kit contains two 1.2mm Style B ring sets (top compression, second compression and three-piece oil ring), the complete gasket set (head, valve cover, intake and exhaust and breather gaskets and small O-rings) and two crankshaft oil seals. It replaces ring set 25-108-01-S. Pistons, connecting rods and valves are not included; this kit re-rings and reseals an engine whose pistons are still good. The rings must match the grooves of the pistons being kept: measure the old top ring (1.2mm for Style B, 1.5mm for Style A) or read the old piston number, and if your parts list shows 24-108-14-S, that is the Style A set. It fits the CH25, CH26, CH27, CH730, CH735, CH740, CH745, CH750, CV25, CV26, CV27, CV724, CV725, CV730, CV740, CV745, CV750, KT715, KT725, KT730, KT735, KT740, KT745, SV710 to SV840, LH755 and LH775. Hone both cylinders for a crosshatch, check for taper, and fit new valve stem seals while the engine is apart; rings will not seal a scored or glazed bore.

• TWO RING SETS, GASKETS AND SEALS - Two 1.2mm Style B ring sets (top, second and three-piece oil ring), the complete gasket set with head and valve cover gaskets, and two crankshaft seals. Pistons are not included; this kit re-rings and reseals the engine.
• REPLACES 25-108-01-S - The Kohler Style B standard ring set, also written 25 108 01-S. If your parts list shows 24-108-14-S instead, that is the 1.5mm Style A set and this is the wrong kit.
• FITS KOHLER 83MM TWINS - CH25, CH26, CH27, CH730, CH735, CH740, CH745, CH750, CV25, CV26, CV27, CV724, CV725, CV730, CV740, CV745, CV750, KT715, KT725, KT730, KT735, KT740, KT745, SV710 to SV840, LH755 and LH775, 725cc and 747cc.
• STYLE B ONLY - Rings must match the grooves of the pistons you are keeping. Measure the old top ring (1.2mm here, 1.5mm for Style A) or read the old piston number before ordering.
• WHILE THE ENGINE IS APART - Hone both cylinders for a crosshatch, check the bores for taper, check the crank journals and rod clearance, and fit new valve stem seals. Rings will not seal a scored or glazed bore.
