Use the wedge at every fourth leaf spring pack. Place the wedge between the inner sides of the spring blades and against the inner adapter, as shown. With the wedge against the inner adapter, press the wedge down between the spring blades. A soft hammer may also be used to force the wedge against the spring blades.
Observe the depth of the wedge. The further the wedge can be pressed between the spring blades, the more the spring blades and inner adapter are worn. The wedge acts like a Go/No Go Gage. Refer to Illustration 9. If the wedge can be inserted past the GO area, the spring blades and inner adapter must be replaced.Guide for Assembly
