PROCEDURE
1 Do a visual check for damage and corrosion. If necessary, replace the relief valve (001,
Figure 11-3).
2 Make sure that there is a clearance (Y) between the flange (004) and the seal plate
(003), thus the O-ring (005) is serviceable.
3 Make sure that the distance X is 133 mm, thus the pressure of the disc springs (002) is
sufficient.
