I have read several posts about how people have re-geared the belt drive system on the grizzly when the got larger tires. My question is, I am wanting to get a 26" tire (probably Mudlite) and was wondering first do I need to re-gear for only 1" difference in diameter? second, If I need to where do I purhcase the kit and how do I instal this modification?

Thank you for your help!

P.S. I do low speed rock crawling and some mud so I need that low range low engagment point...

marine,

I run the 26" mudlites and I purchased a Dalton clutch kit for $89.00 on ebay. EPI also makes a kit but it's more expensive and involves more work to install. I didn't install my Dalton kit, I had my local mechanic install it. The Dalton kit works great and now I can run in high range where before with the 26" I found myself in low range alot. As for my low range goes now, it's right where it should be when I was running with stock tires. I personaly am pleased with the Dalton kit and I would buy again with no hesitation. A lot of guys running the EPI clutch kit swear by it being the greatest there is. The way I see it, the Dalton does a great job and for alot less money. The Dalton kit comes with 8 bushings and a heavier spring and that's what you get for $89.00!LOL Someone is making a bundle on this aftermarket stuff.

WOW!! thats all you get are some bushings and a spring. Makes me wonder where the other $70 goes LOL..

Does doing this decrease the overall speed of the bike? Does it make the low range lower and high range lower? or just change the engagement points? What does this do to the life of the belt?

Marine,

Yeah, makes me wonder where the rest of the money goes too! LOL The clutch kit will not give you anymore speed, it basicaly engages the belt sooner so that the power goes to the wheels sooner. It will change the rate of shift for the CVT. I don't think the kit makes low or high range lower, all it does is change the rate of shift. As for the belt life goes, the manufacturer states it will improve the belt life along with other components when running oversize tires. Check out "DaltonIndustries.com" their website has some good info and read the FAQ section for ATV's. I hope this helped.

Thanks blue_grizzly_04,

I did some reading and have decided to just wait and see once I get my 26" lites if I feel like I have lost any real power.

If the power loss is great, I will buy just the pink and white spring they talk about and not change anything else...If I am correct this will make the belt tighter and allow a lower engagement point? It will not change the shifting points.

MARINE,

When I put on the 26" lites I did notice a minimul loss in power, not much but it was there. I also noticed when riding the very same trails I always ride, I was using low range instead of high like before. Now with the Dalton kit I am using high range just like before with the stock tires. I also thought of just buying the spring instead of the whole package(8 bushings and spring) but I didnt want to go thru the hassle of installing just the spring and find out I needed the bushings also. You can try it and see what the outcome is. I also have heard some guys are using the bushings from the grizzly 600 and have had success with them without using a stiffer spring. I dont know what the difference would be other then the actual weight of the bushings. Maybe the 600 uses a lighter bushing compared to the 660, I honestly dont know. Nevertheless, good luck.

I highly recommend reclutching with larger tires. It will extend your belt life condierably.

The EPI kit is nice... that's the one I got. It includes new springs for the inner clutch to provide more clamping force. If you do lots of mudding or towing, you'll want this kit. I expect the Dalton kit is primarly the clutch weights, which are pretty easy to install.

Thanks for the info!

I don't have the money for the clutch kit (or quite honestly the skills) right now. Maybe, I will find a good deal on a kit somewhere in the mean time. I don't even have the tires yet. Hoping for my b-day gift Oct. 04
