32mm
Dan, what about the new 900 poo clutch, its a 32mm. I just installed one with the updated poo crank in an 05 900. pn 1322520-SP
Would a 32 mm pto offer enough strength improvement?? and still keep it all OEM??
RoadW, Even at 32mm the Polaris design is very poor. The Polaris PTO-end
is bored all the way to the inner crank bearing and the hole is HUGE ( in other words the clutch bolt polaris uses is bigger then it needs to be. )
Also, Polaris runs the thread area to deep and the threaded part is right under the outter PTO-bearing........And when torqueed actually swells
the pto-shaft itself under the bearing causing the inner race to also swell and remove much needed clearance.
These are just some of the problems with the polaris design.
The 900 crank is thick enough in the bearing area so this is not a factor to be concerned about.
Make sense............ ???
The 33mm I offer, has the best of all worlds the clutch bolt is......Smaller, shorter, & the threads are right under the taper where they belong.
And the Cat clutch is actually better and stronger then the polaris clutch.
Plus tuning it is just as simple as the polaris.
Ask anyone that has one and you will find out how well they are liked.
