Chapter Two Decomposition of QR513 Transmission

I. Decomposition Process for QR513 Transmission

1. Bleeding lubricant in transmission

First, drive the vehicle onto a maintenance platform or hoist the vehicle and keep it on a horizontal

plane, screw off the bleeding plug as shown by the arrowhead, and then use a clean container to

accommodate lubricant of the transmission to completely bleed the lubricant in the transmission.

Figure 1

2. Disassembly of external parts of transmission

Switch the transmission to NEUTRAL position; use an appropriate tool to remove the locating seat of

the fork shaft as shown in Figure 2; Connecting bolts for gearshift housing and transmission housing and the

screws for backup lamp switch and idler shaft.

3. Separation of gear shift mechanism and transmission

Remove the gearshift mechanism assembly from the place as shown in Figure 3; as a result of sealant,

the disassembly process may be difficult, so, use such tools as a hand hammer etc. to knock on the bulge at

flank of housing of the gearshift mechanism, and then take out the whole gearshift mechanism assembly

until the two housings completely separate; remember to be slow when taking out the gearshift mechanism

assembly, so as to prevent the return spring as shown in the figure from dropping out inside the transmission;

during disassembly, be careful not to damage the junction planes of the two housings, so as to avoid oil leak

after re-assembly.

4. Disassembly of the connecting bolts for clutch and transmission housings

Use a tool to remove the connecting bolts for transmission and clutch housings as shown in Figure 4.

Remember to remove the bolts both inside and outside the clutch housing when disassembling, and a sleeve

with long connecting rod is required when removing the bolts inside the clutch.

5. Separation of transmission and clutch housings

After the bolts for transmission and clutch housings are removed, separate clutch housing and

transmission housing (Figure 5). as a result of sealant, the separation process may be difficult, so, use such

tools as a hand hammer etc. to knock on the bulge at flank of housing of the transmission, and then take out

the whole transmission housing until the two housings completely separate; during disassembly, be careful

not to damage the junction planes of the two housings, so as to avoid oil leak of the transmission after

re-assembly.

6. Separation of interior transmission parts and fork module from the housing

After transmission housing and clutch housing are separated, keep the clutch housing flat at the place as

shown in Figure 6, remove the bolts for bracket of reverse gear rocker arm, take out the reverse gear rocker

arm assembly and the pin on idler drive, and then take out input shaft, output shaft and fork mechanism

together (when taking out, gently shake, meanwhile, press the driven gear of main decelerator along the

direction of arrowhead as shown in the figure to take out the assembly of input shaft, output shaft and idler

as well as fork mechanism); when taking out, remember to avoid interference between bearing retainer of

output shaft and big gear ring of differential and prevent the bearing retainer from damage.
