flats (KK) on the secondary pump (124) are just

are removing the ratio index clamp.
5. Raise the lever arm (49) off the pivot pin
support (31a).
6. Remove the connecting rod cotter pin (102), if the

the inlet manifold (32). If the secondary pump(s)
need repair, follow the instructions in its manual.
