B Clutch Function
WARNING: This page is about a different variant/trim than selected.
Apply air pressure to the feed hole located on the test plate marked B1 , listen for an audible thud. The piston should not return to its starting position when the air pressure is removed. If air pressure is applied to the B2 circuit, the B1 should return. An audible hiss may be heard when testing this clutch as the seal is designed to allow fluid/air to pass.
