Description

The genuine Kawasaki 11009-2433 is an OEM rocker case gasket engineered to maintain an airtight, oil-resistant seal on single-cylinder OHV utility and mower engines.

Part Overview

• Part Name: Gasket-Rocker Case (Valve Cover Gasket)

• Part Number: 11009-2433

• Function: Seals the rocker arm cover / case to the cylinder head assembly, stopping oil weeping and preventing unmetered air or debris from entering the valve train.

Engine Compatibility

This gasket fits a broad selection of Kawasaki FC-Series 4-stroke vertical-shaft engines:

• FC400V (all major specs)

• FC401V (AS, BS, CS revisions)

• FC420V (AS, BS, CS, DS, ES, FS, GS, HS, JS, KS specs)

• FC540V (AS through LS revisions)

• Kawasaki Mule: Early KAF540 utility vehicles (Mule 2010, 2020, 2030)

Common Equipment Applications

Because the FC-series engines were standard powerplants across commercial and residential turf machinery, this gasket is commonly used in:

• John Deere: Lawn tractors and commercial mowers such as the LX186 (FC540V), GT-series, and 180/185 lawn tractors.

• Toro: Mid-Size ProLine commercial gear walk-behind mowers (such as model 30196).

• Cub Cadet: Heavy-duty walk-behind mowers and yard tractors (G1432, G1436 series).

Service Notes

• Valve Clearances: Since the rocker cover must be removed when servicing valve lash, inspect or replace this gasket whenever setting clearance (standard cold intake/exhaust clearance on FC420V/FC540V is typically 0.004–0.006 in / 0.10–0.15 mm).

• Mating Surfaces: Clean both mating surfaces of any old residue or oil film with a degreaser or brake parts cleaner before seating the new gasket dry.

• Cover Torque: Avoid overtightening the rocker case bolts to prevent warping the stamped cover or pinching the gasket; snug evenly in sequence to factory specification (typically 44–69 in-lb / 5–8 N·m depending on spec).
