tweeked bent or crooked

Anyone have some ideas how to check my bulkhead for true, straight, un tweakedness?

This is what has me curious, but this seam has looked this way since I got it
Its the bottom of the bulkhead

???Does anybody else's look like this???

So can one of you fellow pro owners take a look at your bulkhead seam? Maby take a pic? Or just let me know if yours has a similar ridge?

Is that glue?

I think what a person needs to do if they want to check something for true and square would be to compare to a precision straight edge. Have you tried looking in the shop manual to see if there is a procedure for checking a bulkhead?

Yes that's the lord glue

No I haven't thought to look at the manual. Not usually this kind of info in it but I will check later to verify. Is unlikely though since Polaris dosnt sell the parts separate, just bulkhead tunnel assemblys as far as I know

But it would b nice of someone to look at theirs and see if the ridge is a common thing. Like 3 out of ten have it and its a casting flaw? Possibly? The rest of the halves line up good its just the bottom is a bit off

Find three 5/16 rods and run them through the rear three holes (triangle formation) and see if they are parallel (within reason).

The inner surfaces of the castings with the triangle bolt pattern should be parallel.

Measure from the rearmost side casting bolt hole to the rear shock mount tab/hole on each side. Should be equal on both sides.

Measure from the rearmost side casting bolt hole diagonally to the vertical "ear" hole where the front cross frame attaches. Compare both measurements and see if they are within 1/4" or so.

I wouldn't get all OCD on the the two front clip halves not meeting perfectly on the bottom seam. If, between the cross bolts that hold the front clips together, one edge is bowed down and the other is bowed up, then one of them is tweaked.
