WARNING:

Take care not to get fingers caught when piston is pushed out.

Remove dirt guard (3).
Put a block of wood in front of pistons (4) and press out carefully with compressed air.
Remove pistons. If one piston comes out but the other will not, use clamp 9992809 and rubber insert as a counterhold in place of the removed piston.

NOTE:

Do not separate the two halves. This requires special pressure-testing equipment and special assembly fluid.
