New to Yamaha this year...all my previous sleds used internal track adjuster bolts with lock nuts...Polaris style.

The Yammie of course has the nylock nuts at the rear of the rails.

I have been struggling with the track adjustment since buying this sled new this year 2013 NytroFX

Which way to turn the adjuster nylock nuts to get the track to move??
As in if I tighten the nylock nut on the clutch side will the track move closer to that side or away from it?
Or otherwise explained if I tighten the axle a side does the track move over that way or away from that way?

Is there typically a problem with the adjuster nylock nuts backing off? It seems like they have done so even tho the axle is tightened to spec....75NM

I know the track is stretching as it is new, single ply and studded...but the adjuster nylock nutrs seem to be returning to the same amount of threads showing prior to adjusting them the last couple times I checked??

This sled has extroverts oem and as such I am trying to run the track on the loose side to let it roll free...Fawkin Nytro has a ridiculous approach angle as it is


Thanks
 
You need to loosen the axle shaft before turning the nylon lock nuts. 17mm and 19mm wrenches. Loosen it until its finger tight/free to move.

As far as the direction, if you tighten the nut on the clutch side the track will shift to the oil can side. Whichever nut you are tightening the track will move towards the other nut.
Tightening the nuts tightens your track.

sounds like your breaking the nuts off because your not loosing the axle first.....?

No...I loosen the axle before playing with the adjusters....and tighten it to spec after adjusting....this is no different than other sleds.

I was just wonering if because Yamaha doesnt use a locknut but just nylock nuts on the adjuster unlike other brands if the axle was prone to backing off??

It's prolly just this single ply track stretching more than I expected??
 
I've never had a problem with the nuts backing off. The adjuster nuts even if they back off, the main axle shouldn't move (since its tightened.)

To be safe you could replace the 2 nyloc nuts on the adjusters and the nyloc nut on the axle shaft but I bet the track is just stretching.

The axle nuts will back off on a yamaha to ended a weekend last year with out the nut, wheel, spacer.
