Diagnose method for the abnormal
noise when Quadraider 600 running at
L gear position
After collecting further information from the market, now we can
focus this L gear position noise problem at several points. I
hope you can carry following operation to help us to find out
which part on the vehicle is defective, and send it back to
Taiwan for further countermeasure.
In brief, we concluded that there could only two parts making
this problem : Engine transmission system and Front / Rear
gear box.
Step 1. Shift gear position check
This test is to make sure the shift gear system is set correctly.
1- A. To loose the connecting rod between the shift lever to the engine.
Loose screw to remove the
connecting rod.
1- B. To make sure the gear position is neutral.
When the shift bar is line-up with this
crew, the gear position is NEUTRAL.
1- C. Put the gear Position at L Gear, then test drive to see if any noise
appears.
To push the shift bar to the right end to have the gear at LOW

To adjust the shift connecting rod in the correct position, simply adjust
two screws shown below until all five gear position indication light on the
speedometer all in correct position.
Step 2. Rear Gear box disconnect test
This test is to check if the rear gear box is the cause of the noise.
2- A. To loose and remove the propeller shaft between the shift lever to
the engine (Remove Left Rear Tire to do this job) .
To loose three fixation bolt to remove the
rear propeller shaft.
2- B. After remove the propeller shaft, push the 2WD / 4WD button to make
the ATV run under 4WD mode. Then, then test drive to see if any noise
appears.
If both action (shift gear position check and Rear gear box check ) had been
done and the noise remains, Remove the gasket shown below. If this fails
also, Change engine transmission parts (Check parts catalogue page E12 &
E15 ) .
Remove this green
gasket and test. By
doing this the shift
