Remove

–	Before the operation, measure to see if the valve seat rings can still be re-cut and, if necessary, the sealing surface of the cylinder head. If not, the valve guides cannot be replaced either.

Adjust first base -T20037-, as follows:

–	Insert the angular supports corresponding to valve angle -T20037/21-.5∠°.

–	Unseat the worn valve guides from the camshaft side with the -T20035-.

Note!

If the cylinder head already has guides with collar (reparation), these should be unseated from the combustion chamber side.
