The Polaris "Demand 4 Drive" is an electronically actuated all wheel drive. Using a Hillard clutch to drive the front wheels. I explain how it works, how to maintain it and how to troubleshoot issues.

If u could let me know my problem. I can grab the clutch the inside is splin but turns rollers go up down but does not grab hub

@rondykstra5716 3 ай бұрын

How would you tell if the hub is worn? I have 3 wd. New clutch. The magnet engages. Front left turns sometimes but very slow and only 1 revolution or 2. I have all 4 tires in the air. Thanks for the great video!

You should see a groove in the inside of the hub. You could measure the inside diameter of the hub and compare it with a known good one. My manual doesn't give a speck for that. Also check the magnet coil pole gap. must be between 0.002"-0.004". Check the roller cage for damage and that the rollers move freely and return automatically with the spring tension. Check that the CV axel is turning. Check the drive key.

Any advice would be appreciated. I have a 97 sportsman 400L that I got as "junk" with a 330 magnum and 90s 350L. The 400 I managed to get running it needed head and cylinder work but runs. I haven't gotten a battery for it and just use the pull start. Question- do the 4X4 hubs require a battery to work? for stable voltage.

@MrFixit1 18 күн бұрын

Yes, needs a battery. Don't run this without the battery it will blow all the bulbs and over charge the electronics.

Not sure where you’re located but if near by for some chance would you fix mine?? Used to start now won’t.. I drove it down the rd and brought it back and was smoking a lil white smoke from engine, not sure if I burnt the spark plug. Or what I knoticed it was loud and I was missing a spring for the exhaust. But fluids are good

Question for you not regarding the AWD but you seem to know a lot about this ATV.. I have been watching bout every video u got on this ATV I have a 1995 Polaris sportsman 400.. what would u say is wrong if it will not turn the engine off with the key or with the kill switch.. I had to choke it to kill it .. and my atv is doing this some times and then again some times it will turn off with the kill switch or the key ..

@MrFixit1 9 ай бұрын

Ok, so the ignition coil needs to be grounded in order to kill spark. So I would say something in the ground wires. Check behind the head light mounted on the rev-limiter box with a screw is a ground wire. Make sure it is tight and clean, also check the connection panel grounds that they are tight and clean. I would start there. If this doesn't fix the problem, feel free to ask any questions. Hope this helps. Thanks for watching.

Good morning. First thank you for the video! I have a 1994 Polaris 4x4L-i went to hang some tree stands and when i took me four wheeler off the truck it shut off-so i ended up starting it with the pull cord-when i was using it and shut it off i went to pull start it again and then the pull cord wouldn’t recoil-ended up using a jump box to start it back up-found out-DONT DO THIS! This blew all my light on my machine and i also ended up replacing pull cord and light bulbs and battery-would have saved myself alot of trouble by replacing battery but i was in the woods-i was told the older machines like mine cant take the jump box and found this out after! Wondering what bulb and how to replace the AWD bulb if you can help me that would be great-thats the only one i did not replace and didnt wanna mess anything up! Learned alot about the bulbs and the machine-took some time but what a pain for a simple mistake on my part! Wish i road more but my machine has LOW miles and had it serviced by a friend a while back! He is busy and trying to fix it myself is all. Again thank you for any advice! Have a good day

Do you know what the torque specs are on the hub?

@MrFixit1 5 ай бұрын

This is from the manual. It's a bit complicated It's more of a feel on the hub basically tighten the nut and back it off until the hub rolls with a little bit of drag. 4x4 Models with FlexLoc Nut 1. Torque spindle nut (A) to 400 inch Ibs. more than rolling torque and back nut off 1/2 turn. NOTE: Some 1994 and all 1995 to current models have left hand threads on left spindle. 2. Tighten nut again and read the force it takes to rotate the lock nut (nut rolling torque). NOTE: Rolling torque on FlexLoc nuts should be 75 to 400 inch Ibs. If the rolling torque is less than 75 inch Ibs. the nut should be replaced. To achieve the final torque, add the nut rolling torque plus 100 inch Ibs. Example: Rotating nut torque Plus bearing preload Final nut torque = 125 inch Ibs. = 100 inch Ibs. = 225 inch Ibs. 3. Rotate the hub and front drive axle. Re-torque to the reading recorded in step 2. 4. Some models will have a stake nut. Never re-use a stake nut. Replace with a FlexLoc™ nut. NOTE: A FlexLoc™ nut is shown in the center photo (A).

It dose have a grub screw for to add oil but what oil would mine need ? My bike is always spining its rear tires first then the front kicks in by it self . I don't have a buton to activate the 4x4. Haven't seen the same hubs like mine online yet. They all have wires for electricity going to the magnets to engage it. My bike also has no batterie

Ok after a bit of research sounds like you have an older 1987-1988 Trail boss 250 4x4. which doesn't use electromagnets in the hubs. You can use ATF type-F or the Polaris demand drive fluid.

What's it mean when your driving in 4wd and your front tire feels like it binds up and turns your tire and pulls the machine that way lime it's turns but you are going foward not turning?

@MrFixit1 5 ай бұрын

Sometimes the Hillard clutch gets stuck, and you have to change gears forward or back to unstick it. If you were backing up in AWD and you switch to forward, and it binds up, switch to REV in 2-wheel drive and goose the throttle and the hub will release. Prety normal to happen every now and then. Try NOT to keep driving in this condition as it could cause damage to the hub or Hillard clutch.
