My bike sounds like it's missing a gear in 2wd or it's lost bearing, but when I click the switch in to 4wheel drive system on its not as bad ....how do I find this problem its sounds like its the front but not sure ....help me plz!! Thank you in advance !!

Nathan, great video. I have a set of Polaris tracks and the front diff has bound up a second time. The dealer who replaced the front diff the first time indicated to me that it wasn't anything to do with the tracks. I'm not sure that was accurate info. The front tracks hub is a different diameter than the rear. However, all tire diameters are equal. Need your input please!!

I saw this video and was hoping i can figure out what's going on, if anyone can help me with this issue it would be greatly appreciated.

The rear wheels actually spin faster than the front wheels. The front wheels only engage when the rears are slipping.

My 2000 polaris scrambler 500 is slightly different. Still functions similarly but not exactly the same. It has a front differential "gear box" that is centered between the front wheels. That has a shaft out each side that connects to the CV axel, which connects to the "Hillard clutch" that is located inside the wheel hub assembly. There is some sort of "slip differential" to the system when you are in 2WD. When you are in 2WD and stuck in mud, the front wheel(s) will engage automatically. When you move the selector to "AWD" it will in fact give power to the front and rear wheels at all time. I believe that just one of the front wheels engage at a time but I'm not sure...it my be both. Another way I have seen this work is when the chain popped off the sprocket on the rear wheels. When it did this, the quad was still driving by using the front wheels only, and this was when it's in 2WD. There is nothing broken with it, this is how it work. I saw others comment on seeing just 1 front wheel spin in a video and were concerned there were issues...that's not the case. The person in the video just had it in 2WD and the rear wheels were spinning. The AWD selector locks the front and rear together whether you are spinning or not. I love the system. There really is never any need to set it to AWD, as the quad automatically sends power to the front when needed.

There is definitely power to the front in 4wd, my 2006 scrambler had a bad chain so I was replacing it but had to wait a few days and I was able to ride it in 4wd using only the fronts to pull me along. So it definitely does get power to the front on its own, I did however notice in sloppy conditions the front tires can actually spin a bit faster on occasion than the back tires. I've been looking into this 4x4 setup as I'm trying to learn how I can make a 4x4 race quad, using some Polaris parts.

If I understand your question, you are asking if there is a differential action between the two front wheels, and the answer to that is no. When the on-demand 4x4 kicks in, the two front wheels are locked together.

@@mapo130 In order to test the system this way, you'd have to have all 4 wheels off the ground so that the back wheels can turn freely and you can see if the front wheels turn when you engage the system by pushing the button. Running the ATV like that would be dangerous though, and I don't recommend it. A good real-world test would be to get stuck in a giant mud puddle and see if all 4 wheels turn or just the back ones.

@armedfarm34292 жыл бұрын
The rollers in the cage will turn just a bit to wedge against the output drive splines. In other words, the round rollers wedge hard, steel to steel 'over center', once over center they will drive the 2 splined outputs. Think leverage! The rollers have leverage when the magnet is on. Works the same in reverse.

One thing that you left out that is crucial to the operation is that the front gear is a different ratio than the rear. With the front locked in and all four spinning, the rear tires will turn 5 times and the fronts 4 times.

Good system or is traditional 4x4 better??? in terms of reliability seems like it would be best to engage 4x4 while theirs no power going to wheels. Also if you have your front wheels pinned up against a rock or a log your going to have to slip your back tires for the front wheels to clim up over the obstacle.
