any way to let secondary float?

[hot rod rooster]

i am a believer in letting the secondary float about 1/4 inch on jack shaft. with the way the rx's jack shaft is held in place by the tappered colar if you let it float you run the risk of having the collar come out a bit and bugger things up.

has anyone cured this problem?

Don't know what you're talking about, the secondary clutch floats from the factory. Some of the collars came out from the 03's, but there is an updated collar and retaining NUT for 04 that holds it in.

on the secondary side of the jack shaft my bearing is pressed into the bulkhead and there is a little tapered collar that fits around the shaft and pushes into the inside of the bearing. there is nothing but the physical presence of the clutch to keep the tapered collar from coming out. the only thing i can think of to fix this is getting a new bearin same o.d with a locking collar and putting it in so the locking colar is to the inside of the chassis.


does yammy have an update for this? if so i'm on my way to the dealer!

Not to mention the fact that the collar on 03 was NOT held in by the clutch, it was held in by being PRESSED in and LOCTITE.[/b]

it was a pretty poor press job, it slipped right out then i took the chaincase off. there is a little bushing in behind the clutch that dosn't allow it to ocme out when the bolt onthe clutch is tightened up.



how do i ask for the bearing upgrade is there a part number i can order the new locking collar?

I had to pound the living crap out of mine to get it apart when I changed the bearing and did the update.

jack shaft

a few of usw had a problem with this set up. yamaha fix this in the 04 model by threading the sleve and installing a lock not on the inside. just ask for the coller from and 04 or 05 model the bearings are still the same it is a 6206k if you can find one at a bearing supply place. i to like to have little floot like the manufacture recmends to make up for small manufactureing indifferce,s

note

note that when you put the new style coller and nut on that you should lock tite the nut i had to stake mine on as i have spun the nut off. notist it right away as i lost 250 rpm as it was enuf of a loss of center to center to shift up in the secoundary to soon un less these black sleds have just to mutch torqe and power

You will have to pay for the different parts, it not paided by Yamaha. The secondary does float, spec is .040" to .080". Why would you want more?

Skidoo did a study some years ago with regard to "floating secondary clutches" and short and skinny was that you don't want it to float...you loose power to the track, the sled is faster with it locked into position.

Line it up and lock it in place!

Make sure you're not side loading the bearings when you lock it up and you're good to go.

Ditto what SuperStroker says. NEVER LET IT FLOAT! I set all RX-1's up with a thick rubber O-ring to apply constant pressure towards bearing. It won't apply to much pressure and bind the brgs., just enough to hold driven in place where it's designed to be. IF IT FLOATS, IT WILL BIND UP ON THE SHAFT EVENTUALLY, AND YOU WILL NOT HAVE CLUTCHES THAT STAY IN ALIGNMENT!
