The valves should adjusted to the following specifications: .005 - .007 in. for the intake valve and .009 - .011 in. for the exhaust valve. The valve gap is measured with the piston 1/4" past the TDC on the power stroke.
Go to http://outdoorpowerinfo.com/engine_specs/briggs_valve_gaps.asp for a listing of Briggs valve clearances. You'll need your model number which will be on the engine shroud or rocker cover.
Need to know the engine model and type.
It is the gap between the rocker arm and the push rod or valve in the head of the engine. How much it is varies with each model of engine.
There is no valve adjustment for that engine. If you have valve clatter you must have worn valve train parts.
You can perform a valve adjustment, on your 3412 Caterpillar diesel engine, by rolling the engine to the number one position. Tighten the valve adjustment screw. You will need to do this for each piston position.
Check the engine shroud, and if it is a v-twin, check the OHV valve covers.
The valve clearance on a Briggs and Stratton 21 HP OHV engine is typically set to 0.005 inches for both the intake and exhaust valves when the engine is cold. It's important to check the specific model's service manual for any variations or specific adjustments. Proper valve clearance ensures optimal engine performance and longevity.
The valve lash on a Briggs & Stratton 17 hp engine typically ranges from 0.005 to 0.007 inches (0.127 to 0.178 mm) for both the intake and exhaust valves. It's essential to check and adjust the valve lash periodically to ensure proper engine performance and longevity. Always refer to the specific engine model's manual for precise specifications.
For the aluminum the intake valve clearance is .005 to .007 inches. exhaust valve clearance is .007 to .009 inches. Cast iron is - intake valve is .007 to .009. inches exhaust valve is .017 to .019 inches
