Got mine replaced on warranty, go to another dealer or contact HD direct, your dealers talking *****.

 

My 10" HD shield I put on my SG cracked after I had it in for warranty work. I asked the dealer about replacing it and they said nope, after market trim and they did not install !

 

My 10 inch Windsplitter started cracking after about 6 months around the mounting holes. Dealer replaced it under warranty no problem even though I installed it. The dealer claimed that I over torqued it, but I didn't argue since they were giving me a new one. I installed the replacement and torqued it to Harley's exact specifications. Now the replacement is developing very small cracks at the same place. I've placed electrical tape around the edges of mounting holes to pad them. Close inspection of the holes revels that the hidden edges are very poorly finished and not finished at all in some places. I like the Windsplitter, but if this one continues to crack I'll replace it with an aftermarket.

 

I put on a Clearview shields recurve and it developed cracking. They replaced it in a heart beat, no questions asked.


I have read a number of articles and they all point to overtightening as a reason for the cracks.

 

Cracking -

1- Over tightening of the screws
2- Windshield pouches can allow excessive flexing of the shield
3- Bumping into it multiple times stresses the mounting point
4- HD OEM shields are Lexan polycarbonate with a hard coating. Due to vibrations, often the hard coating will develop multiple small cracks that look like its all the way through but are not.
5- If several windshields crack in the same place, its not the windshield but most likely installation.
6- Tall shields are more prone to cracking than shorter ones are.
7- Lower quality materials ( often used to reduce costs) can be more brittle than higher quality materials. Just because it says Lexan or polycarbonate doesn't mean its the correct chemical formula for a windshield.

Anyways... just my opinion.

 

Rule #1 Make sure the "keyhole" slots on the windshield do not touch or it will be stressed when you tighten it down. I found mine stress cracking from that . I made my own and gave it plenty of "play" problem solved and that was 3 yrs ago
