I took off the actuator and the rectangle piece at the end is moving with ease. I took of the round cylinder on top of the actuator and it can also move. I flipped the switch for 2wd and nothing moved at all. It seems there is no power going to it.
Yes everything moves in the diff and I turned the bike on and nothing still happened. I'm guessing it might be the switch because it has rust all in it so I ordered a new one and hopefully it will work.
did you move the quad, or jack it up so the wheels are all off the ground and hit the gas then hit the switch? speed has to be registered on the meter for it to try moving the actuator. (bad wheel speed circuit will not allow 4wd)
he said the screen says 2wd, so if it thinks its in 2wd it wont do anything, when you shift to 4wd or back. unless its moving
so if the collar will go forward, see if the 4wd disengages ( if you have it up in the air the front wheels should turn without the back ones). when my bearings where messed up in the diff it wouldnt shift out of 4wd because the actuator couldnt move the collar far enough on the shaft
Make sure when you put the actuator back in the side of the diff, that the pin (that moves the small rectangular block that fits into the collar inside) is in the right position. If the switch is in 2 WD the pin should be at 9 o'clock when held in your hand with the top up, or at 12 O'clock when in 4X4. It mover clockwise to 12 for 4X4 and then back counterclockwise to 9 for 2x4 if working properly. It is easier to put the actuator back in the diff. if the pin is at 12 and the switch in 4X4. If the pin is at any other clock position, you can pop the wire connector apart, push paper clips into the red & black wire holes and connect a battery charger alligator clip to one paper clip & touch other charger clip to the other paperclip to spin the actuator until it gets to the right position. Somehow my friends had spun to 6 O'clock, which should be impossible, and would not go into 4X4. Spun the pin to the right position and worked fine.
