Shift Linkage Assemble

  1. Install the gear position guide on the shaft. Press the shaft until the middle groove is located centrally on the opening in the gear position guide.
  2. Install the dual interlock on the shaft and install a NEW rollpin.
  3. Install the tension spring taut with the spring ends on each side of the pin.
  4. Install the lockring. Do not place the preload washer on until the gear-changing mechanism has been fitted in the gear box.

    IMPORTANT: While assembling shafts, ensure that the shift shaft block notches line up.
  6. Install all shift shafts partially onto the shift control bracket assembly. Partial insertion of the shift shafts provide considerable end play during the installation of the gear shift mechanism.

    • the shift position mechanism's shaft to the shift control bracket assembly hole (1).
    • the shift control bracket pin to the shift position mechanism shift pattern (2).
    • The brass double position blocker to the shift shaft block notches (3). The brass double position blocker should be aligned properly with the shift cylinder.
