SHIFT RAIL AND FORK INSTALLATION
The shift rail interlock pins, balls and plugs must
be installed in the correct sequence for proper shift-
ing. Refer to the installation diagram (Fig. 85) during
assembly.
Coat the intermediate plate shift rail bores
and the interlock balls, pins and plugs with a
thick covering of petroleum jelly before assem-
bly. The jelly will hold the interlock compo-
nents in place making installation easier. Use a
pencil magnet to hold and insert the interlocks.
Then use a small screwdriver to push the inter-
lock components into place.
(1) Coat reverse rail interlock pin with petroleum
jelly and install pin in rail (Fig. 86).
(2) Install reverse shift rail in intermediate plate
(Fig. 87).

in both shift forks (Fig. 94).
(11) Verify that none of the interlock balls, plugs,
or pins were displaced during shift rail installation.
(12) Install and tighten shift fork setscrews to 20
Nzm (14 ft. lbs.) torque (Fig. 95).
(13) Install 1-2 and 3-4 shift rail C-rings (Fig. 96).
(14) Insert fifth gear shift rail through reverse
shift fork.Then slide rail into intermediate plate
just far enough to secure interlock ball. Do not
fully install shift rail at this time.
