How To Clean and Repair the Yamaha 4x4 Push Button Switch for Free

[@williamhearn270]

I watched your video last evening. Took my problem switch apart this morning the way you demonstrated, it works like a new one!!! Thank you. Fred

[@501PartsTech]

Man, that is awesome. I’m glad to hear that! Thank you for letting us know. Have a great weekend.

[@tomhighman6872]

My grizzly was not shifting from 2 wd to 4wd. Followed your directions and fixed it in 5 minutes. Hardest part is getting the ball bearings placed on the springs during assembly. Thanks for the video 👍👍👍

[@tzzzz20]

My Differential Lock was not working. I took of the switch and cleaned it as instructed. Lo and behold it works.

[@arielaltamirano2794]

My Kodiak 450 2003 was shifting ramdomly 4x2 to 4x4 and diff lock ligth starts blinking, so I tried this and it works! Apparently the corrotion avoid the switch to have contact with the electric tablet of the wires. Nice video!

[@francineganmor9952]

Awesome content!! I have a 450 and 660 Rhino, both have sat years. Both ran to where they sit. Put new batteries in both. Both are dead stick. No N light, no lights, no NOTHING! Power to hot side of solenoid, nothing past there. Common sense says it is corrosion somewhere,and most likely, same problem on both buggies. Zero power at ANY fuse and zero behind the key switch. I didn't bother jumping across solenoid as obviously there is a bigger problem than just starting. TIA !!

[@edspam4350]

Thank you. I was having a problem with my 2016 Kodiak switching into and out of 4wd without touching the switch. I asked my dealer about it and they gave the same advise as your video. Worked . Thanks again.

[@andyvanorden115]

Cleaning the switch was ultimately the problem?? My 2016 grizzly 700 is doing the same thing.

[@newfoundlandoutdoorsman2892]

Worked for me as well..Thanks

[@brianhumphries3590]

Thank you so much fixed my buddies and mine in 20 mins we are telling all our friends your the best

[@501PartsTech]

Brian Humphries appreciate it, glad to help!

[@danthemanf5555]

Awesome video man. Just saved me a trip to the dealer!

[@say-dq1th]

Thanks! Mine was stuck in 4x4 mode, wouldn’t switch to 2nd. Just did the repair, works like a charm!

[@501PartsTech]

Awesome! Glad to help!

[@DSawyer556]

I used this video to fix the random shifting problem I was having with my 2013 grizzly. Thanks for the info. Awesome!

[@arielaltamirano2794]

What's your problems looks like? Im having a random shifting problem too.

[@darrell5363]

Mine would go into 4x4 when I’m. Road running going like 60kph, no I didn’t touch the button lol, I’m gonna try the dielectric grease thing tonight

[@01hondascott]

@@darrell5363 did it work, imine constantly goes in and out of 2wd/4wd constantly while i'm driving, back and fourth back and fourth the whole time im using it.

[@darrell5363]

@@01hondascott yeah taking it apart and cleaning it fixed it totally its been fine since

[@racingruss7263]

Saved me money...Thank you.

[@mikecochrane2074]

Thanks for your videos. Great help! After all the tests, my difflock light is still flashing, and not engaging to difflock. The previous owner thought he may have shorted something out. I notice that some difflock leads come out of the cdi box. Could it be possible that I may need to replace it to fix my problem? Thanks!!!

[@501PartsTech]

Mike, yes that is very possible. The CDI does have a play in the 4wd system. It will put the machine into limp mode if you are halfway between 4wd diff lock with diff lock not being fully engaged.

[@mikecochrane2074]

@@501PartsTech Ok. So that would be why it cuts out and doesn't run right when switched to difflock.... Got it! How do you feel about the aftermarket boxes? Really can't afford an OEM.

[@501PartsTech]

@@mikecochrane2074 Yes, That depends on what you are trying to do with the machine. I have seen it go both ways with aftermarket boxes. I always stick with OEM if possible.

[@mikecochrane2074]

@@501PartsTech I know I should stay with the OEM. I am gonna try a Moto1988 CDI. Hoping for the best @30 bucks. Thanks for your time.

[@billwickham7986]

Great video! I have read the dielectric grease is an insulator. Do you put the grease on the actual contacts?

[@501PartsTech]

Yes you put it on the actual contacts

[@lukeduke221978]

Excellent Video!!!! Really appreciate your Help!!!

[@KittyHawk71]

Can you do this without unplugging harness?

[@ricksundberg5659]

My 2005 Yamaha Grizzly won't go into 4x4 when I push the button, the locker button won't make noise either. I'll be trying this first light tomorrow. It seems unlikely both motors could have gone out simultaneously. Hope it works! Great video.

[@ricksundberg5659]

Yep, wasn't the switch but the contacts were pretty bad so I got them cleaned up. Is there a video showing how to change the servo ?

[@ricksundberg5659]

Is there a fuse that could be blown somewhere?

[@ricksundberg5659]

How fast can I get one of these? I live in Northern California and am leaving for a hunting trip next weekend. Also, is there a fuse for this I should check?

[@ricksundberg5659]

I read USPS express priority shipping but how many days is that?

[@justinledoux4938]

So ofcourse the silly ball bearings fell out of the slide switch when I took it apart. I found 2 of the little ball bearings, how many were in there originally?

[@501PartsTech]

Should be two ball bearings in there.

[@brianhumphries3590]

They go on top of the 2 springs

[@johnhartgrove7249]

I did the same thing but can't find them. Would you know the size of the ball bearings?

[@curty85]

Would you sell new boots if they a were the case with mine?

[@501PartsTech]

I don’t have any of the boots. They are not available to sell individually from anywhere.

[@Tommo220]

Mike Grizzly switches into four-wheel-drive but won’t switch out of four-wheel-drive does this problem still apply to me?

[@501PartsTech]

It could be your issue, but you won’t really know until you start testing all of the components. If you go to our website 501 parts.com and click on the troubleshooting page at the top you’ll find information to troubleshoot all of the components and videos.

[@Tommo220]

@@501PartsTech I tried this technique and it didn’t work but I will make sure to check your website

[@donlawrence8810]

Question. I just replaced the battery on my Yamaha 660. After a few days, it won't start. When you start it, you have to step on the break, and then turn the key to start. I have noticed over several months that I have to really step hard on the brake pedal to start the engine. What do you think I need? Could it be a starter relay?

[@501PartsTech]

Adjust the switch on the brake that tells the machine the brake is pressed

[@donlawrence8810]

@@501PartsTech Thank you for getting back to me. I will try that today.

[@KG-wg5jx]

Thanks 501!! Great video.

[@KG-wg5jx]

Thanks again. 501. Mine was sketchy switching between 2wd and 4wd. It would change out when I jiggled the switch. It was weird, I wasn't sure which way to go, but I pulled the switch per your instructions and greased it up and now it's working fine! I have to admit that your accent is pretty strong, funny shit. I am in MN, and you couldn't get more different than I hear up here. HAHA. My wife overheard me watching your video and she had to ask what the hell am I watching. LOL. All good man, thanks again! 2014 Grizzly 700 EPS

[@stevehinson5350]

So my 2003 grizzly 660 the differential light will not go off and speed limiter is on also my display doesn’t show if your in four wheel drive need help.

[@stevehinson5350]

501Parts Customer Support thank you I will try some of these steps. I watched all your videos on the front differential. I checked the servo it is definitely working and I slid the front diff fork to make sure it was engaging I have not tested the relays yet also someone cut and spliced the wiring harness plugs to the servo I would like to verify the wires are correct so do you know what’s what on that also what make no sense is if I unplug the display I don’t hit the speed limiter.

[@davebrookbank4831]

Thank you

[@chandlerjahn7501]

looked it up but says part out of stock

[@mr.mr.3301]

There is a service bulletin on this. In short the new part has an upgraded return spring.

[@darrell5363]

I got that recall done and it didn’t fix the 4x4 kicking on for no reason

[@bryantgwb007]

The red button on mine won't stay i when pushed

[@501PartsTech]

It's probably and issue with the springs inside the switch.

[@bryantgwb007]

@@501PartsTech awesome! Thank you for the fast response buddy. I sent an email to the website with another question.
