Default Primary Outer Shiv damage

Hey HCS'ers,

Got a primary on the RZR that one of the "Fingers" over extended, and shredded the cover.

I pulled the clutch out using a DIY Tool

And was able to clean and inspect things closer.

The area of the finger that overextended outward had some of the casting broken away. It's about 1 inch in width and 1/2 inch in height, at the fingers base so i would think not only is it a belt shredder, but also a destroyer of engines as it is out of balance.

I have researched that Aluminum castings can be tig welded.

I ordered a new replacement, but.
The question I have is, can it be repaired and balanced for under $400.00, and does anyone in Wpg, or MB do so?

What I would like to do it have it repaired, and refurbish it to keep as a spare, or sell it to someone who might need it down the road knowing its done 100%. (recoop some $$) .

The old part Number is 1323013
The new part number is 1323255

Thoughts, advice?

I put this in the Sled section as Primaries for Sled are similar, with similar material, no?

Thanks guys,


Shoe.

I dunno, but it did.

Pic shows damage.

on top of that on Sunday on ebay there were 3 or 4 of them up for sale "Just for parts" with the same sustained damage.

Weird eh?

The roller should not allow the flyweight to come even close to doing that, something else must have happened..what number weights were you using? Where they modified in any way?

Stock Stock Stock.

Crazy that this happened...

Before the failure the clutch was sticking... fingers were holding it in the higher speed position. I had to open the cover and love tap it with some wood for it to return.

Not called fingers, "flyweights" or Cam arms just for clarification.
Something else is at play, could be the Spider height is shimmed incorrectly.

"Overextended" is a synonym for how Shoemaker drives. Every part on that thing is overextended.

Here is the reason why the damage occurred to me, and can occur to others.

It looks like wear on the pivot bolts for the weights on the primary has worn down, and there for allowed the weights in certain conditions to be able to over extend (as the bolts rotated in the mount).

3500 miles in and there you have it.

Again, anyone know who could weld fill the unit and balance it?
