installed drag n fly clutch kit today

[crsublime]

ive never done any sort of work with the clutches on any snowmobile before...I do however turn wrenches just about everyday in the winter on anything from excavators to pickups to small cars...have always wrenched on my own vehicles etc...

Overall the install was pretty easy...my setup followed the directions except i added .5 grams to the shoulder...so its pretty much 5 washers plus lock washer on shoulder, 2 washers on the center...nothing on the tip...and just the bolt on the end hole i dont remember what its called...

everything went smoothly except i installed the weights with the clutch on the snowmobile....i looked everything over before i did it and it didnt seem like it would hurt anything and i was careful...my main reasoning for this was i couldnt figure out how to get the clutch off... maybe someone could help with that...

anyway i put them in and the hardest part of the whole install was putting the much larger and stiffer red spring in. After help from a couple of buddies trying to push it in we looked at it and came up with a great idea...the center bolt of the secondary drive threads right into the end of the primary shaft...so we stacked a bunch of 3/4 inch washers on the bolt and threaded the spring and cover down enought to put the 6 smaller bolts in...then we took the center bolt back out and put the original one in...put the belt on then threaded the secondary bolt back in...it worked out quite slick...are snowmobiles designed that way on purpose?? pretty damn clever if they are....

as for the performance...the conditions were ideal for tractions with a 34 degree that earlier today and then a refreeze of 29 degrees by the time i was done... and with no track spin and the new clutches holy #*$&@...i didnt have anywhere near enough room to go much over 65 and it was damn hard to see the speedometer so i dont know speeds but my sled now accelerates incredibly well...good luck holding the skiis down no matter what suspension set up u have....all i can say is it is a damn good investment for 250 bucks...

Ditto on my drag n flys!! another way to do the clutch kit is to use 9 differnt length bolts (3 of each length) and alternate them until you get the stock bolts back in. (i did mine that way cuz i didnt have a bunch of guys to push it in).

To get the clutch off, you need a clutch puller bolt.

you dont need to pull the clutch tho. works fine without pulling it.

Try installing the red hc spring when the clutch is on the crank!!!!!!

Haha, what he said. Try installing the red spring with the clutch off the sled for that matter. It's a chore, but easy to make a compression tool out of threaded rod, washers and nuts.

I did install the spring with the clutch on the crank, can you say holly *&^*^$, but I got it on. I compressed the spring while my buddy threaded the bolts.

With the Clutch off the sled the Red spring is pretty easy to install. Simply grab the Movable sheeve with your fingers and place hands on the clutch cover. Then using your knee and hands compress the spring. It's nice if you have a friend there to put the bolts in but if you don't simply let go with one hand and install a couple bolts.

I did. and it really wasnt that bad. as i said, i used 3 different length bolts (3 of each, 9 bolts total) and just sucked the outer cover in by alternating holes. It really wasnt bad at all. I like all your wisdom and help turk, but....... if a person has half an ounce of ingenuity, it can be done, and with not alot of difficulty.

no the easiest way is to take out the center bolt from the secondary clutch...it threads right into the shaft of the primary...with about 10, 3/4 inch washers it cranks it right down then u can put in the six bolts its kinda weird i was wondering if they designed it that way

 

[crsublime]

we have a good supply of nuts and bolts at our shop where i did the work but most of them are quite coarse threads so none of them would work but the bolt from the other side works perfect

I'm using a yami puller to pull the primary of my nytro... how hard should i have to torque the puller before the clutch pops off? I don't want to damage the threads and I feel as though I was putting quite a bit of weight on it.

You really have to crank it. Then it will pop off and scare the bajesus out of you. First time I did it I though I broke something.

for stubborn pull offs or if you dont want to have to torque that hard....pump a tablespoons worth of grease deep into the primary....the hydraulics will pop it off easily...just clean the grease off the taper and crank hub with a rag when your done...

the easiest way to install the red spring and other work etc is a dummy clutch tool....this compresses the cover from the center...the problem with some of the other ideas (which Ive done in a pinch) is you can bugger the cheap cover bushing ...
as to the secondary bolt with washer deal...I suppose if the thread pitch was exact and no part of the bush came into contact with the bushing it would the closest to the dummy tool...

Thanks I'll give her heck. ;-)
