In need of Urgent Help! 166-174 not working!

[SnoDmon]

Wut do I do? Got the 174" under her ('05 900 RMK 166") with the 10's(& MMP 9" offset) and the b!tch won't stretch it tight enough! Do I do a rail set back and F up the geometry and the bottom out cushions, OR do I drill new holes in the tunnel and build a custom drop bracket on the rear? Either way I don't wanna do it because suspension geometry is so critical. My old sled was a '96 with a '99 suspension and that was a S.O.B. gettin' that suspension back under it. The 900 just "dropped" in and only took 20 minutes to bolt everything up. Please help a.s.a.p.! What's easier? Which way is a better bet to NOT F up the geometry?

Well how were you planning on making up the 4" difference to begin with? besides maybe the 1 1/4 or so of wheel difference?

I agree totally with 1500psi. I think your easiest solution might be 4" extensions considering the larger idlers only take up about 1 1/2" of the longer track at most. Good luck.

just did a 151 to 159 with adding 8 inch wheels we did the rail extension also, only way to make up the difference

Yeah about the only way I was able to make up the difference without extensions was a big whel kit stretching my 156 to a 159 on my old edge. 166 to 174 is quite a stretch.

JUST DO THE SET BACK! 15 minutes and problem solved I set back a 1992 phazer 12 inches for a 159 and it rode the same have also done this on my wife's 700 rmk not that big of a deal everyone complaining about geometry, its a 174 all bigger mtn sleds ride rougher than a short track damn it deal with the performance and flotation not the ride!!! just my $$0.02

What tooth drivers did u put on. If you did the 7 tooth, the 9's would suck up a good 2".

 

[Nelson]

Are you wanting to do rail extensions? What about getting ahold of extensions from 151-159 to add on your 166 rails? seems to me it is the same differance going from 166-174.


Crappy thing is that I just sold my new spare 166 track for the amazing price of 250.00 because I didn't need it anymore.

Shouldn't the 10" wheels take up 3" more than a 7" wheel if I had the offset of the relocation bracket forward.(Assuming only a third of the wheel's circumfrance touchs the track) I have it mounted backwards so that relocation offset should take up another 2-3 inches. so I'm gettin 5-6" of stretch. So a 2" setback ought to do the job and I was thinking 2-1/4" anyways. with the adjusters tightened all the way i could pull the track about a inch off the wheels? 2-1/4" sound good?

Arctic1, You wanna build me those rear brackets tonight?

 

[rockin rmk]

when you go from 7" wheel to 10" wheel you will only gain 1.5" not 3" you would need a 13" wheel. Hold you 7" whel up to your 10" wheel and you will be able to tell.

 

[SnoDmon]

well i was thinking about circumferance. That sounds like center to outside which is radius. which is 5 so I get what your saying. 7 to 10 is an 1.5" difference radius. but don't you have to take into account the amount of track around the wheel. Say it touches 45% of the wheel. You take 10x3.16=31.6" circumfrance. So 31.6x0.45=14.22". Compared to 7x3.16=22.12, then 22.12x0.45=9.954" So isn't that about a 4 inches difference. I don't know, maybe im figuring wrong. but it makes sense to me. Just that I'm assuming it touches 45% of the wheel. But 33% wouold probably be a better % to use.

If you think your 900 steered hard stock, wait untill you set the skid back 2 1/4".

IMO that is too much setback.
