Chapter 4 Transmission System
Section 1 Transmission
Structure
5TH Transmission is a synchronous transmission. It has five onward gears and one reverse
gear. It shifts gears through three synchronous sits and four shafts (input shaft, main shaft, centre
shaft and reversing gear shaft). All of the onward gears are joggle style and reverse gears are gild or
annulus structure.
Low speed synchronous sits are equipped in the centre shaft, and it fits with the 1
ST
gear or 2ed
gear in the centre shaft. High speed synchronous sits are in the input shaft, and it fits with the 3ed
gear or the 4
th
gear in the input shaft.
5TH synchronization in the input shaft joggles the gear of the 5 TH in the main shaft.
Shift setup and the optional shaft are fixed in the above of the transmission shell,
with Cam to avoid shifting from the 5 TH gear straight to the stall of reverse.
Maintenance must be used in the material of sealant manufacturer or equivalent with the sealant
in the jointed surface of the aluminum gearbox. Tightening bolts with torque wrench to the required
torque. Thoroughly cleaning all the parts and then assembling after they are dry.
