A valve spring compressor is used to remove collets in a car. The tool compresses the valve springs in the cylinder head of the car allowing the collets to be removed.
A valve spring compressor
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.
KD Tools Valve Spring Compressor 3087
Assuming you mean the exhaust and/or intake valves. # Remove the heads # Borrow, rent or buy a valve spring compressor # Use the spring compressor to compress the springs (one at a time of course) # Remove the valve stem "keepers" # Push the valve out through the head.
The Mark 8 does not have a check-valve in the air suspension system. Each air spring has a solenoid valve, which controls fill and vent of the spring. There is a fifth in the suspension compressor itself, which controls venting the system. I discovered that the seat for vent valve was corroded in my compressor, which would then leak when the system was trying to fill. This resulted in the compressor running, but the car lowering. I was able to clean the seat up for a temporary repair, but ultimately replaced the compressor.
Yes, you remove the rockers, add air pressure in the cylinder through the plug hole and use a valve spring compressor to remove valve spring. You can now change the valve seal.
u need remove cylynderhead then camshaft then rockerarms then use a valve spring compressor then change your valve rubbers.
Special Tools Needed; Fitting to pressurize the cylinder. Good compressed air source. Proper Valve spring compressor. This can be done with the head on the engine. You will need a fitting to screw into the spark plug hole that you can apply a steady source of compressed air to hold the valve closed. Remove rocker. With valve spring compressor that clamps over the top of the spring cap and into a lower portion of the spring, Compress the spring until you can pry the two half moon keepers out. A magnet helps! Carefully lift the spring assembly off. Reassemble and compress the new spring and carefully slip it back into place. Carefully reinsert the valve keepers and release the compressor. Reinstall the rocker, check your manual, Usually about a half to one turn tighter after the slack is gone.
A valve spring "keeper" or AKA a valve spring "retainer" is used to lock a valve spring to the valve.
air operated- spring return
Once you've removed the head, not long at all. You just need a valve spring compressor and fingers that can make those silly retainers fit into the little slots. * Or you can change them with the head still on - just make sure the piston is TDC on the cylinder you are working on - they make a spring compressor that will bolt onto the rocker arm boss for compressing the spring.
If the head is still on the engine, you can purchase a kit at most auto parts stores that includes: an air fitting to keep the cylinder filled with compressed air to prevent the valve from dropping into the cylinder, and a special wrench to attach to the rocker stud and press down on the spring retainer while you remove the locks. If the head is off the engine, you will need a valve spring compressor, which is a large c-shaped tool that pushes on the valve's head on one end and the valve spring retainer on the other end. Also you can buy/rent a valve spring compressor that you can use while the head is still on the engine but you will still need to blow air into the cylinder through the spark plug hole to keep the valve up.
