7A-2 MANUAL TRANSMISSION
General Description
Construction and Servicing
The transmission provides five forward speeds and one reverse speed by means of three synchronizer mesh
devices and three shafts-input shaft, countershaft and reverse gear shaft. All forward gears are in constant
mesh, and reverse uses a sliding idler gear arrangement.
The low speed synchronizer mesh device is mounted on counter shaft and engaged with counter shaft first gear
or second gear, while the high speed synchronizer mesh device is done on input shaft and engaged with input
shaft third gear or fourth gear. The fifth speed synchronizer mesh device on input shaft is engaged with input
shaft fifth gear mounted on the input shaft.
The double cone synchronizing mechanism is provided to 2nd gear synchromesh device for high performance
of shifting to 2nd gear.
The countershaft turns the final gear and differential assembly, thereby turning the front drive shafts which are
attached to the front wheels.
4WD model is equipped with transfer assembly on transmission being mated to right side of differential output in
transmission.
For servicing, it is necessary to use genuine sealant or its equivalent on mating surfaces of transmission case
which is made of aluminum. The case fastening bolts must be tightened to specified torque by means of torque
wrench. It is also important that all parts are thoroughly cleaned with cleaning fluid and air dried before reas-
sembling.
Further, care must be taken to adjust preload of counter shaft taper roller bearings. New synchronizer rings are
prohibited from being lapped with respective gear cones by using lapping compound before they are assembled.
