Could be. I was glad it was something simple, but disappointed in myself that I took the whole differential apart first! Thanks for watching, and hopefully that's the problem!
Hoping for some guidance. I have a 2003 Kodiac 450, problem is no forward "zero" it grabs reverse no problem, just no forward gears? Any direction would really help...:) Some clicking sound like yours but looked in the parts catalog and shows nothing of the part your referring to? So confusing......
The part I'm talking about would only come into play with four wheel drive. Reverse/forward would be fine. The issue you're describing is likely inside the transmission. Perhaps a pawl is broken or a gear is stripped. It might also be worth checking the shifter and linkage. I would visually verify that when you move the shifter gear to gear, it is moving the bellcrank on the transmission gear to gear. Sometimes the shifter mechanism can strip out so the linkage won't move. Here's hoping it's something simple like that! Otherwise, you'll probably have to pull the transmission, split it, and look for broken gears or pawls....
@@3DayWeekend Thanks friend, I did check the shifter, has a little play in it but is moving the bellcrank. Looks like a crack open coming. But is the bike worth I'm asking myself?
Longshot here but I just got an 01 400 4x4 Kodiak and my issue is when I press the 4x4 button, I can hear the actuator in the front but nothing happens after that… any ideas?
It could be the exact same problem I had in this video, or you could have something wrong inside your differential. Knowing what I know now, I'd check the coupler first. If you still can't get it to work, crack open the differential and take a good look at the actuator mechanism. You should be able to test that right on the bench. Hope that helps! Good luck to you, and thanks for watching!
There are a couple things you could check - first would be your shifter linkage. Sometimes the shifters will develop some play and you'll be unable to shift it properly. I would take the shifter assembly apart and isolate the shifter linkage, then move it by hand. If you can shift through the gears, you'll just need to work on the shifter. If it still doesn't shift, there could be a problem with the transmission. Hopefully it's just your shifter!
@@3DayWeekend Thank you for that, did take off the shifter "rod" cover to make sure the gear teeth are properly lined up with the dots...., I 'do" notice The shift handle up front section does have a little play in the shaft that goes back to the two gears under the cover, is that what you mean?
Thanks for the video. My 03 bruin 350 wont go into 4wd mode. The 4wd light comes on and i can hear the motor engage when i press the drive selector button but thats it. After jacking up the front i spin one wheel and the other wheel isnt turning, i think they should both turn, do you have any idea? thanks
Only one should spin on this type of differential. If you hold that one wheel that is spinning, then the other one should start spinning though. This machine has a traditional differential in the front (without DIFFLOCK) so that you can still go around corners and be able to steer with 4x4 engaged. Some models have the DIFFLOCK option so if you're buried you can engage both front wheels, but it'll only go in a straight line until you turn it back off. Hope that makes sense... Sounds like you may have the exact same problem as I did. Everything seemed fine unless I put any kind of load on the front end, then that coupler would slip. Hope that helps! Thanks for watching!
@@3DayWeekend Thanks for your reply I just looked at it again I have all 4 wheels off the ground When it's in gear and in 2wd the front drive shaft spins when I give it throttle Of course the front wheels aren't turning When I put it in 4wd and engage the throttle the front drive shaft does not spin It wants to and there is a very noticeable squeaking sound from the driveshaft I can manually turn the shaft in both directions and the front wheels will turn If I spin the wheels manually the front drive shaft will spin, just not on it's own I'm thinking it's the shaft itself The sound is like a squeaking belt No grinding or knocking
That part is called a "Gear Coupling". Part number 5GH-46123-00-00. Part number 38 on PARTZILLA: www.partzilla.com/catalog/yamaha/atv/2001/kodiak-4wd-hunter-yfm400fan/front-differential
I believe it was called a Gear Coupling. If you go to Partzilla.com, drill down to your machine and it will be in the Front Differential parts diagram and list. Hope that helps! Thanks for watching!
Oh yes, I did it dirty on that one! I didn't show it, but I did mention at around 10 minutes that I was going to "clean it off". I power washed the entire thing, inside and out, and blew it dry. The outside of the housing is stained so it doesn't look perfect, but all of that loose dirt and mud was completely gone. Thanks for keeping me honest!
“Didn’t split where I was expecting… pulled out here not there..”
Foreshadowing if I’ve ever seen it 😂
Glad you got to the bottom of it!
Haha you know it! Yes, I was glad too. So far so good with the new part!
Next week im going to buy a similar bike and its stuck in 4x4 this video was exactly what i needed to decide on buying it thank you.
You're welcome! Hopefully it is a great machine and you are able to enjoy it. Thanks for watching!
@@3DayWeekend West The Name the part
Thank you very much for documenting this, very helpful to me!!
Glad it was helpful! Thanks for watching!
Nice job. Difficult diagnosis you had to get to the bottom of.
Thanks! Had me stumped for a while, but we got it! It's still running like a champ.
I recon this is the same problem my one has just started making that noise

You are amazing thank you for your video and information 👍👍
Wondering if any has trouble with a Kodiac 2003 450, Will only go into reverse? Nothing forward, engine just runs....?

@@3DayWeekend Thanks for your reply
I just looked at it again
I have all 4 wheels off the ground
When it's in gear and in 2wd the front drive shaft spins when I give it throttle
Of course the front wheels aren't turning
When I put it in 4wd and engage the throttle the front drive shaft does not spin
It wants to and there is a very noticeable squeaking sound from the driveshaft
I can manually turn the shaft in both directions and the front wheels will turn
If I spin the wheels manually the front drive shaft will spin, just not on it's own
I'm thinking it's the shaft itself
The sound is like a squeaking belt
No grinding or knocking
I don't get why videos like this leave the most important parts out
What part are you missing?
What is that part called I might have the same issue on my quad please and thank you

No offense but I'm a mechanic myself and I'm cringing because you didn't clean all the dirt off before disassembly.
