  1. Refer to workshop manual to remove cylinder head from vehicle to expose the valves. A rough sketch of the head showing the various connections may help to ensure that all parts are correctly re-fitted. Please note that replacement gaskets will be required for cylinder head, rocker cover, and in some cases manifold and carburetor.

  2. Place the head on wooden blocks to prevent damage to either valves or machined base. After checking that new head gasket is identical, old head gasket can then be removed and discarded.

  3. Where fitted remove clip from split collets. Before using compressor always loosen collets from spring cap. This can be achieved by using a short piece of metal tube and light hammer to strike spring cap (not valve). Failure to do this can result in damage to both engine and compressor.

  4. Assemble valve spring compressor with handle in locked position. Ensure that jaw end is aligned squarely on spring retaining cap and centre of valve head to clear collets.

  5. Ensure that there is no sideways movement as actuating screw T-Bar is screwed down to compressor valve spring and expose collets. If spring cap refuses to free and release collets, lift locking lever to release compressor and repeat step 3 above.

  6. Remove collets and release locking handle to remove compressor. Always release pressure on compressor by slowing releasing locking handle before removing tool from head. Valve spring and collets can be ejected at high speed if compressor is allowed to slip. Valve spring assembly can then be removed from head.

  7. Tool is now pre-set to compress next valve spring. Repeat the valve removal procedure for remaining valves. Keep all parts from each valve together in its original position.

  8. Remove all carbon deposits and any remains of old gasket from cylinder head. Taking care to avoid damaging machined face of head. Carefully inspect and clean all valve seats, valves etc. Re-grind/re-cut valve seats as necessary and re-new any burnt, bent or damaged valves.

  9. Re-assemble and re-fit head following workshop manual procedures.
