Checking contact surface for rectangular rings in cylinder "B" for wear
^ Check contact surface - arrow - in cylinder "B" for wear.
^ Contact surface must not be heavily scored and/or show blue discoloration.

If no blue discoloration and only small grooves are detected, proceed as follows:
^ Sandpaper (600 grit, oiled) contact surface 1 to 2 times.
^ Carefully wipe off with a clean rag and check contact surface.
^ Contact surface must now be like new. If scores cannot be removed in this manner:
^ Replace cylinder "B".

CAUTION: Wear protective glasses.

^ Lightly coat bore for valve ball - arrow - at front side with oil.
^ Charge valve ball from rear with compressed air.
^ Only little ball stroke (hardly visible).
^ Ball is not spring-loaded (moves back slowly). If valve ball does not seal properly or is stuck:
^ Replace piston "B".

Note:
^ A valve ball that does not seal properly or is stuck will cause slipping in reverse gear





Checking coated and outer plates for wear

Signs of overheating on outer plates point to worn coated plates. Evaluate signs of wear as follows:

A - Spot of discoloration of outer plates caused by overheating in distance of more than 20 mm: Outer and coated plates OK can be reused.

B - Spot of discoloration of outer plates caused by overheating in distance of less than 20 mm: Outer and coated plates worn, must be replaced.

C - Tarnish blue/brown at outer and/or inner area of outer plates: Outer and coated plates overheated and worn, must be replaced.
