What are the steps for valve disassembly and installation?
1 Answers
Valve disassembly and installation steps are as follows: 1. Remove the valve adjustment shim. 2. Remove the intake and exhaust valves. Use a valve removal pliers to compress the valve spring, then remove the lock piece, spring seat, valve spring and valve in sequence. 3. Use needle-nose pliers to remove the valve stem oil seal. 4. Use compressed air and a magnetic rod to remove the spring seat and washer. 5. Remove the half-moon key. The installation of the automobile engine valve group only needs to follow the reverse order of disassembly. Notes: Do not scratch the valve seat ring, and the valve oil seal should be replaced with a new one to avoid unnecessary trouble.
