Thanks for posting this video ! My Kodiak 400 is a 2000 model with no issues but being 20 years old I decided to change the belt. Thanks to your video the install was easy. BTW the belt didn't look like it needed changing. I'll keep the old one as a spare . . . but I think its going to outlive me. LOL
If your Keeping the Old one as a spare Why not Just put a "New" used one on This Time ?
@@bestbudssmokeshop5587 I bought the new one first ! I just got in my 22 mm long impact socket this week. Planning to repack the grease in the primary CVT when it warms up. I put anti-seize on all the 10 mm nuts and bolts. I may look like the tin man when I'm done ! LOL
It's not only about the belt looking old/cracked that necessitates a replacement. It's about mic'ing the thickness of the belt. As the belt wears, it reduces in the thickness and if it gets out of spec, it needs to be replaced, regardless of how it looks.
Great video!! Thank you. Short sweet and to the point
Glad it was helpful!
Thanks for the video, I’m upgrading my 04 450 kodiak. I plow a lot of snow, this upgrade might give me the added low end torque for said plowing.
Great video ,Great Description
Thanks!
For me skip the take belt off, must be in a million pieces, it’s a 2001, in 2021, all hard miles. Polaris could take a lesson, 20 yrs on this belt was amazing. Umteen moose, plow Ed a km driveway in northern Ontario, great video. The cage wouldn’t come off, took a bit.
Thanks for the comment and Happy Thanksgiving!
Do you have a video on how to adjust the timing on a 2018 Kodiak 450?
I'm sorry, we do not.
Здравствуйте,скажите пожалуйста,а нужно вариатор продувать?или там есть какая-то вентиляция?У меня Кодиак 400 2004 года
What are the shims use for..??? And why only one clutch or pulley has gears ..?
Everything ATV-UTV-Reviews is that output shaft for the 22mm nut on the clutch, is that a reverse thread
Thanks for the video, you showed and explained everything so clearly. How many shims did you use? Looks like there were 4 in the package but you only used 2? Can you post a link of where to buy the shims please. Thanks again.
Thanks for the comment. Believe we used 2 shims, the main thing is you don't shim it past where the splines connect to the sheave. Here are some on ebay...www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.Xkodiak+450+shims.TRS0&_nkw=kodiak+450+shims&_sacat=0
Sorry to comment on a old video but after you put the belt back on is the clutch still supposed to move in and out by hand like it did before the belt went on? I just did this mod and I noticed I couldn't slide the clutch in and out after I put the belt back on
Have a 16 grizzly. Just added heavier 8ply tires. 500 miles on machine. Should I change belt like you said? I did order up a shim kit. Thanks in advance.
Changing the belt is not an absolute have to at this point, but while everything is apart it would be a great time to do it.
Did you notice more low end power with shims?
Thanks for video. I have 2016 Cub-Cadet Challenger 750cc Crew and it doesn't have much take off power and seems to take forever to get to top speed . If its just me in it, it will get up to 53-55mph but takes a half mile or close to it to get to that top speed.....I just want it to take off quicker and get to 15-20 mph without sounding like I am running wide open with high RPMs. I ordered a 4 shim kit that will be in today. Someone else said I needed to change the weight of rollers. I am just about positive the factory is 18gram....and I think I need to put lighter weights? Let me know if I am on right track. Thanks in advance
Dennis, thanks for reaching out and apologize about the slow response. Please let us know how the mods you made worked out, I'm not personally familiar with these machines.
@Everything ATV-UTV-Reviews that's fine....I get it for sure. I found a couple videos that may help. I just have seen so much controversy about heavier vs lighter roller weights.....my thinking is lighter weights wil "sling out" quicker and "roll back in" quicker... which would close the movable sheave faster and the result would be quicker take off, lower top-end speed but again....a vehicle that's 12.5ft long and costs over $10k new, I definitely don't want to be running 45-50mph....lol
Dennis, we've never changed weights... Typically the shim kit will gear it down without much else needed. Please follow up with what you find.
Do you always tighten that 22mm nut with an impact? Everything I’ve read people say to always torque it to 100ft/lbs.
Just have to use your own judgment on it... if you use a impact just don't overdue it
I know you are more mechanical than I am and I was hoping you could help. I just bought a 2003 Yamaha Kodiak 450 from my brother in law, with low hours just 273. He garage keep it and did all of the pm on it for years. I believe that I need to adjust my rear break because the foot pedal has a lot of play and the left hand break can be compressed fully with very little brake action. Any help would be greatly appreciated and I would be able to save face with my brother in law.
Jeff, can't remember exactly how that setup was. Look for anything on or around the cable ends that looks adjustable. Adjust it one way and check... if nothing readjust the opposite direction. There is nothing that you can permanently damage by giving it a try. Thanks for the comment!
Thanks for the video, it's very well done. Do I understand the concept correctly that the shim mod would give me more usable power more quickly if I am say towing a trailer with a load or using the Kodiak on bad ground?
John, thanks for your comment. Yes, the mod adds more usable power on the bottom end. The drawback is it does take away a couple MPH from the top speed. Also, if you've not already watch this video and register for some free product. ruclips.net/video/1DDCN1BSYZk/видео.html
Thanks for the reply and link. Would the shim mod be a problem on lots of hilly ground, meaning higher risk of flipping the bike over? It's a farm bike, and we've nothing but hills.
The shim mod will lower the overall gear ratio on your Kodiak. The mod is great for those looking for improved performance or those like ourselves seeking a gear ratio better suited for hills and work. Inexpensive alternative to a larger displacement quad...
Me and dad put on 3 .75mm bolts on my kodiak 450 and when we put it on and everything back together the belt was slipping like crazy it felt like it made it geared too high we’re gonna take off 1 and see
Zach, replace the belt when you do this mod. Also clean the surface area where the belt goes up and down on the primary clutch, the clutch closest toward the front wheels. Make sure the primary clutch is engaged into the splines also, to much shim and it will NOT catch the splines. Check the video out at 3:07 for more information
Zach, how did your shims work out?
Everything ATV-UTV-Reviews. The shins are fine it’s that one of our roller/weights were broke when we do it off. And the dealer said it probably was a factory problem because it shouldn’t have broke even if we over torqed it. But we got my rollers and now we’re waiting on the special grease for the clutch and I’ll let you know what happens then.
@@zachwood8562, thanks for the update. Once you get it back together let us know how the shim mod performed
Everything ATV-UTV-Reviews they work fine
Is that a clutch kit that makes it easier for your atv to spin bigger tires
It is shims that allow the belt to sit lower in the primary clutch, which gives you a slight gear reduction. Not a bad investment for a couple $$$.
How many mm are those each?
1mm, .5mm, .3mm and .2mm = overall for a 2mm shim
Can you send me or tell me where you got the shim at cause I can’t find any online
Search "yamaha grizzly clutch shims" on ebay
Leave it Stock OEM...it last longer. Leave the shims at the store.
I HATE this video hahah! I bought a Kodiak and it would not keep up with my buddies on the trail, but I swamped them in the mud. I ended up undoing this mod, you lose a huge amount of top end - it’s equivalent to not having a fifth gear! Lost almost 7mph.
Thanks for the comment.
You bought the wrong type of machine if you're trying to hit a top speed. ATVs are meant to traverse any terrain. If you want speed buy a 2WD sport quad, super sport bike or fast car. If you want to go seriously off road and through mud, you need strong low end power and 4x4.
@@FlawleZ31 I mean getting there. I'd be a good 5 minutes behind them some times. I went back to stock.
I do not understand the words (I presume) he is speaking.
Then look for a video in your native language.Tthough if you can type it I fail to see why you don't understand fairly plain English.
