Step 1 : Remove the spark plug and securing the spark plug lead away from the spark plug.
Step 2 : Remove the muffler, crankcase breather and any other components that block access to the valve chamber. Step 3 : Remove the cylinder head bolts and take out other bolts from the engine components to reach the valve chamber. Label the bolts if necessary, to ensure proper installation later, since they may be of different lengths.
Step 2 : After removing the spark plug and securing the spark plug lead away from the spark plug, adjust the jaws of the valve spring compressor part number until they touch the top and bottom of the valve chamber. Step 3 : Push the tool in until the upper jaw slips over the upper end of the spring. Tighten the jaws to compress the spring. Removing Valves: Keyhole Retainers. Step 2 : Slip the upper jaw of the valve spring compressor over the top of the valve chamber and the lower jaw between the spring and retainer.
If the engine design does not permit the upper jaw to fit over the top of the valve chamber, insert the upper jaw into the chamber over the top of the spring, so that the spring is between the tool's jaws.
Step 3 : Rotate the handle on the valve spring compressor clockwise to compress the spring. Then, slide the retainer off the valve by shifting it with needle nose pliers so that the large part of the keyhole is directly over the stem. Use the pliers to remove the retainer from the valve chamber. Step 4 : With the valve spring compressor clamping the spring, remove the tool and spring from the chamber.
Then, slowly crank open the valve spring compressor to release the tension and remove the spring. Removing Overhead Valves Overhead valve designs vary from one engine model to another. Step 2 : Remove the air cleaner assembly, fuel tank, oil fill tube, blower housing and rewind starter, muffler guard, muffler, carburetor and any other engine parts that block access to the cylinder head.
Step 3 : Remove the screws from the valve cover, using a socket wrench or nut driver. Step 4 : Remove the rocker arm bolts with a socket wrench or nut driver. Then remove the rocker arms and push rods. Step 5 : Remove the valve caps if equipped. They are seated on the valve stems. Step 6 : Use your thumbs to press in on the spring retainer and valve spring over one of the valves.
With the valve spring compressed, remove the retainer. Step 7 : Remove the push rod guide bolts and push rod guide. Step 8 : Remove the cylinder head bolts and remove the cylinder head by rocking it with your hands. If necessary, loosen the cylinder head by striking it with a nylon-faced hammer. Never pry it loose, as this may damage the head. Step 9 : Remove and inspect the valves, guides and seats following the steps below. The intake and exhaust valves often are made of different steel alloys and may be different colors.
Step 1 : Check the valve face for an irregular seating pattern. The pattern around the face should be even with the valve head and of equal thickness all the way around. It there are stubborn deposits, clean the valve with a wire brush and solvent, soaking the parts for several hours if necessary, to loosen hardened grit.
Step 2 : Run a fingernail or credit card along the valve stem once you have cleaned it. If you feel a ridge, the valve stem is worn and should be replaced. The valve guide may also be worn and in need of a replacement.
How to Lap Valves You can smooth out minor scoring and pitting of the valve face and seat to restore a valve's ability to seal the combustion chamber by lapping the valves. Step 1: Apply a small amount of valve lapping compound part number - a fine, but abrasive paste- to the valve face and insert the valve into the valve guide.
Step 1 : Apply a small amount of valve lapping compound. Step 2: Wet the end of the lapping tool suction cup and place it on the valve head.
Spin the valve back and forth between your hands several times. Step 3 : Clean the surface frequently and check your progress.
Lap the valve just enough to create a consistent and even pattern around the valve face. Step 4 : Once lapping is completed, clean the valves thoroughly with solvent to ensure that ALL of the abrasive residue is removed. Any particles that remain can rapidly damage the valves and other engine components. Step 1 : Place the valve spring into the valve spring compressor and rotate the tool's handle until the spring is fully compressed.
Step 2 : Insert the compressed spring into the valve chamber. Step 3 : Brush the valve stem with valve stem lubricant. Then, lower the valve stem through the spring. Step 4 : If pins are used, insert each pin with needle nose pliers.
If automotive-type retainers are used, place the retainers in the valve stem groove. Step 5 : Lower the spring until the retainer fits around the pin or automotive-type retainer.
Then, pull out the valve spring compressor. Step 6 : Reinstall the crankcase breather and other engine components. Step 1 : Valves with keyhole retainers do not require an additional retainer. Compress the keyhole retainer and spring with the compressor tool - the large hole should face the opening in the tool - until the spring is solid. Step 2 : Brush the valve stem with valve stem lubricant. Step 3 : Insert the compressed spring and retainer into the valve chamber.
Step 4 : Insert the valve stem through the large slot in the retainer. Step 5 : Reinstall the crankcase breather and other components.
