4 Push Rods 24-411-05-S Fits Kohler CH18 CH20 CH25 CH730

Set of four push rods that fits the Kohler CH18, CH20, CH22, CH23, CH25, CH620, CH640, CH670, CH680, CH730, CH740 and CH750 twin-cylinder engines and the CV, ECH and ECV versions of the same engines. Replaces part number 24-411-05-S, also written 24 411 05-S and 2441105. The factory rod is sold individually, and a twin uses four of them, two per cylinder, so this set does the whole engine in one order. The same push rod part number serves intake and exhaust on these engines, so there is nothing to sort on the bench. The part spans both the 77mm and 83mm families. If you are replacing bent push rods, find out why they bent. These engines use hydraulic lifters and have no valve lash adjustment, and a lifter gummed up from neglected oil and stuck at full extension will jam the valve train and fold a rod. Inspect the lifters and change the oil. After assembly, turn the engine over by hand through a full cycle before cranking it so the lifters can bleed down. Rocker arms, rocker nuts, lifters, valve cover gaskets and valve covers are not included.

• SET OF FOUR PUSH RODS - Replaces part number 24-411-05-S, also written 24 411 05-S and 2441105. The factory rod is sold one at a time. A twin-cylinder engine needs four, so this set does the whole engine in one order.
• ONE ROD FITS BOTH INTAKE AND EXHAUST - A single push rod part number serves all four valves on these twins. There is no separate intake and exhaust number to get wrong, which is not true of every engine in this class.
• FITS KOHLER CH18 TO CH750 TWINS - CH18, CH20, CH22, CH23, CH25, CH620, CH640, CH670, CH680, CH730, CH740 and CH750, and the CV, ECH and ECV versions. This part spans both the 77mm and the 83mm engines, so the displacement question that catches people out on rings and pistons does not apply here.
• BENT RODS USUALLY POINT AT A LIFTER - These engines run hydraulic lifters and have no valve lash adjustment. A lifter that has gummed up and stuck extended will jam the valve train and fold a push rod. If you are replacing bent rods, pull and inspect the lifters as well, and change the oil while you are in there.
• TURN IT OVER BY HAND BEFORE YOU CRANK IT - After assembly, rotate the engine through a full cycle by hand to let the lifters bleed down and to confirm nothing is binding. Rocker arms, rocker nuts, lifters, valve cover gaskets and valve covers are not included.
