HOW TO INSTALL AND TUNE A CVTECH TRAILBLOC PRIMARY CLUTCH

[@NorthCountryBoyz]

The air guitar is taking form well 😎 I am not a CanAm guy (obviously) but a great video to throw up man! This is what a lot of people do go looking for an more often than not it's the little things like this that can't often be found! I won't be making it this weekend but we will definitely be making another ride here really soon. The new wheeler is on it's way this week while I am gone but at least now I will have two so there shouldn't be any concerns about not being able to ride now 😬

[@LyndhurstXMRMY]

North Country Boyz SHOULDNT, he says. I have a distinct feeling you might!

[@NorthCountryBoyz]

@@LyndhurstXMRMY Bahahahaha. We will have to see how the upgrades handle the riding for this year. Scrambler returns to be this week and the work will begin for the rebuilding.

I’m adding my new Trail Block primary to my wildcat Trail 700 but already have the Dalton kit spring in my old primary …will my Dalton spring work with the Trailbloc clutch …THX 😃

[@LyndhurstXMRMY]

@@Carcajoo121 im not sure, you'd have to measure the diameter of the springs, but id say probably not

[@Voffroading]

thanks for the video it was very helpful. I recently got my cv tech clutch but I'm not happy with it and I need some help. there was a drop-down bar when I was purchasing this clutch that was asking what size tires, I selected 29/30's but definitely not working right, I have a 2023 outlander xmr with K&N intake and full HMF Titan Exhaust the bike also is tuned with dyno jet power vision 3 running ATV Terminators 29.5X10X14 on MSA Wheels, my stall/Engagement went from 1800 stock clutch to 2900 RPM that's way to high and also, I know that the clutch is slipping is not grabbing the belt hard. when I get on my bike, and I hit the throttle, and the rpm jumps up the bike starts to pull but there is time where I fell the belt slipping cause out of the sudden you can hear the motor RPM spike up a bit then grabs again. my stock was running way better :) if any of you guys can tell me what weight and spring, I should run I would gladly appreciate

[@LyndhurstXMRMY]

What size motor?

[@LyndhurstXMRMY]

Id do a 1020 - 18 gram weights

How well does this setup work in mud. Do you like it?

[@AmotorB]

Hey man. Love the video! I have a question. So I tried the same set up you got. Same weights same spring. I have a outlander 850 XMR and I'm trying to turn 29.5 assassinators. With this set up I'm engaging at 2900rpms and the machine feels sluggish. Does that mean its got more power to turn the tires or the opposite? Wasn't sure if the heavier the spring and the lighter the weights the more power to turn the tires

[@LyndhurstXMRMY]

Yeah the 850's require a different spring and weight combinationnall together

[@AmotorB]

@@LyndhurstXMRMY okay thanks man! I'm gonna try to find out what works with it

[@Carcajoo121]

I’m running 30 x10 x14 tires

[@livelaughlove20able]

I’m getting ready to install a cvtech primary clutch on a can am 650 outlander max xt with super atv 29.5 assassinators tires which comes pre-installed with a 1025 spring and 16 gram weights my question is does that sound right I was told to go with a 1014 spring instead of the 1025 just wondering if you might know thanks

[@LyndhurstXMRMY]

You're gonna wanna go with a 1020 and 12-14gram weights. A 1024's engagement is way too high and a 1016 is basically stock engsgement

[@livelaughlove20able]

I meant your cvtech primary clutch

[@PrairieOffroad]

Can am 1000 xxc, 32” assasinators, I’m going to put 1020 spring, I want told you have to include the weight of the sliders, but I don’t agree, I was thinking 20-22g weights

[@LyndhurstXMRMY]

Well yes, you have twuce the bike as i do and more aggressive tires

[@PrairieOffroad]

@@LyndhurstXMRMY got it dialed in perfectly at 22 gram weights, so if you include the sliders it will be 34 grams.shifting out at 74/7500, in high, and same with low under load, thanks!

[@FakeDongers]

Hey man, I recently started trying to calibrate my cvtech. I got 21 570 on 31s, originally was set up by peakboys with a 1024 spring and 8 gram weights. Ended up calling local and they said they could set me up, the gave me a 1019 spring and 6 gram weights. I got a little more top end which I was looking for as it would only ever hit 6400 rpm now it’s 7000 however it feels a lot more sluggish off the jump. What would you consider for maximizing power band but not losing top end

[@LyndhurstXMRMY]

Exactly what i ran! I had a 1020 and 12 gram weights!

[@FakeDongers]

@@LyndhurstXMRMY perfect ill just stack these weights and get a 1020 spring! What was your shift out at im super curious. with the 1024 and 8 grams I have an insane amount of power taking off with 2700 engagement I believe and 6300 shift out but it just didn't get up there in rpms. It would top out at 80km (on speedometer, definitely not accurate) at around 6400 rpm so I feel like I should try and get it to top out a little higher although I don't want to lose that bottom end its super fun.

[@LyndhurstXMRMY]

@@FakeDongers it would never shift out in high and id be doing roughly 110-112

[@stones-xcel3666]

What weight did you have before changing it?

[@xNELVKALEN]

Do these clutches always come with a one way bearing? Currently trying to fix a hard shifting problem/lurch. The belt was rubbing the inside sheave of the primary, which in the process of addressing this, I noticed the middle flat area between sheaves ,where the one way bearing would be, is static for mine. I see a lot of rubber wear in that section as well. I’m thinking I need to pull this off and inspect further.

[@LyndhurstXMRMY]

Sounds like you secondary might not be set back into the helix forks properly

[@xNELVKALEN]

@@LyndhurstXMRMY could you explain the “helix forks”? I just replaced the secondary and it appears to work. It does adjust to rpm as it should. It seems to drive well other than it is difficult to shift between high low or reverse etc.

[@LyndhurstXMRMY]

From what you said, "the belt is rubbing on the primary" that means your clutches arent put on all the way, in seeing the primary clutch is held on by a non compression bolt/stud, i dont think the issue is your promary. Your secondary clutch has a helix-shaft sleeve-spring-inner sheeve-outer sheeve then bolt or nuts. The inner sheeve has three slots in the back of it. The helix has three forks. The helix must have its forks inserted into these slots when installing the clutch or ut will put distance between the secondary and the backplate. Meaning your secondary will be further out causing your belt to rub on the outerr sheeve of the orimary! This is going off of what you are describing. Theres also 1000's of other variables.

I can’t find a cv tech anywhere for my 650xmr are they the same as a 570?

[@LyndhurstXMRMY]

Yessir! All cvtechs for canam atvs are the exact same, cvtech makes a gen 1(smooth weight cover) gen 2(ribbed and vented weight cover) both gens will fit any canam 2012+ you will just have to buy the 12g weights and 1020 spring seperatly

I have the 1021 spring and 14 gram weights and engagement at around 2800-3000rpm but am hitting limiter a lot when full throttle from a stop. Should I go with a 16 or 18 gram weight to get out of limiter on the start so bad ?

[@LyndhurstXMRMY]

Try a 1020 spring

[@CDoylee1]

@@LyndhurstXMRMY ok that’s kinda what I was thinking, I’ll order one and see how it works. Thanks

[@mattgardner7869]

Hey man, thanks for all the advice you're sharing. Can I ask what the rpm rev limiter is? I have a 2021 Outlander 650 xmr as well and had the 1020 spring with 18 gram weights but the machine does rev to high and activates the Visco-lok almost instantly because its so aggressive. its a 2400rpm shift out and the issue I was having was it was dragging to get to top speed almost as if not shifting out completely. I just changed to the spring to part 0951-1016 which is a lighter initial spring rate from 300 to 200NM but the same final spring rate of 1200NM and its shifting at 2000rpm. I used a 16 gram weight and a penny behind it to boost the weight to about 18.3grams. It shifts out at 7400rpm and comes down to 6900-7000rpm as it shifts through. Not sure I can get better than that. I would like to raise the RPM a little just before rev limiter but I don't know what that is. I have a 16gram and 18 gram weights right now. I may just put the 18grams in to get a little more RPM. I'd appreciate hearing how you made out.

Forgot to mention I'm running 31" Moto Havocs

[@CDoylee1]

@@mattgardner7869 I tried the 1020 spring and didn’t make much of a difference, went to the 1017 spring, brought my engagement to around 2200rpm, for weight I believe I have 14gram weights 7105. Shift out is around 7600rpm with 31 motohavocs and stock secondary. Pretty comfortable with it now

Amel Šahman hard to diagnose without seeing, did you pull the clutch apart before installing, try watching it with the belt cover off to see if its your primary or if its somewhere else? Did you use loctite on the primary bolt or a brand new one ?
