18.15.Use a 12mm socket wrench to remove the
sixteen perimeter bolts from the transmission
housing.
NOTE: Support transmission so the transmission
input shaft is not resting on the table.
18.16.Separate the transmission housings by using a
pry bar at the reinforced pry points provided.
See Figure 18.16.
18.17.Remove the right side housing.
18.18.Use a 12mm wrench to remove the bolt holding

18.19.Lift and rotate the shift arm far enough to allow
the shift block to be removed, then remove the
shift block.
NOTE: If the shift block and shift collar show
abnormal wear or discoloration, the shift rod or
the shift interlock may be out of adjustment.
18.20.Lift the input shaft and reduction shaft and
remove the chain from the sprockets.
See Figure 18.20.
NOTE: An accurate measurement of chain slack
is difficult to make. If the transmission has more
than a thousand hours of use, or if the Big Coun-
try shows evidence of heavy usage, replace-
ment of the chain is recommended.
NOTE: The most likely cause of chain breakage
is shock loading in Reverse gear. If the chain is
broken, insure that the shift interlock is working
correctly before returning the unit to service.
NOTE: When the bearing on the bottom of the
input shaft clears its bore in the housing, the
input shaft can be leaned toward the reduction
shaft, creating slack in the chain.
18.21.Remove the input shaft from the transmission.
18.22.Remove any shims from the bearing bore. Keep
track of the shims.
NOTE: With the input shaft removed, the reduc-
tion shaft can be lifted and moved clear of the
differential.
18.23.Remove the reduction shaft.
