This item is an authentic Kohler replacement part that has been sourced from the original manufacturer to be used with small engines. The gasket is used to seal the connection between the cylinder and the cylinder head. This item also includes the exhaust gasket, but is priced as a single part.
1. Cub Cadet design makes you take the bracket for the gas tank off, the gas tank, fuel pump, and the engine shroud on the Kohler SV 725 24 hp twin engine.
2. Remove valve cover on cylinder that needs repair.

wil be past the coil/spark plug wire by as much as an inch before the piston starts its motion down away from TDC, then remove valve rockers and push rods from head. Note which push rod is intake and exhaust (upper-lower) and mark which is which because they need to be installed in the cylinder as they were
4. Disconnect exhaust pipe on both cylinders. Then remove intake manifold from both cylinders.
5. Loosen and remove 4 cylinder head bolts that are located on the head (2) and under the valve rockers (2).
6. Pry head off of cylinder without damaging cooling fins on head/cylinder.
7. Remove old gasket from head and cylinder. This area needs all old gasket material removed to install new gasket properly. Make sure it\'s very clean. Install new gasket.
8. Install head making sure gasket stays in place. The cylinder should have 2 dowel pins to help locate gasket and head in proper position. Tighten in 2 series of torque sequences, first at 15 ft.lbs, then tighten 4 head bolts again at 32 ft. lbs.
9. Install valve push rods remembering the order you removed them; upper in the upper port, the lower in the lower port. Install valve rockers making sure the rocker is located on push rod and valve.
10. While engine is still at TDC, use gap gauge to measure distance between valve stem and rocker. This distance should be between .002\" and .0035\" inch for both intake and exhaust on this particular model of Kohler. Tighten or loosen the large adjustment nut on the rocker arm to adjust the gap between the rocker arm assembly and valve stem. Your model could vary. Check spec sheet for your individual engine model.
11. Once your gap between the valve rocker and valve stem is achieved, lock the adjustment nut down tightening the 25T torqs bolt inside the adjustment nut. Rotate the engine by hand to make sure all is working properly, then return to TDC on the compression stroke and re-check your valve/ valve rocker clearance.
Assemble everything you took apart in reverse order. I think that\'s it.

Both cylinder heads had to be removed (lack of compression), the deck of the block and the mating surface of the cylinder heads had to be checked for flatness.
