What would cause 753 tilt valve bonnet to fail?

Aksnocat · 2023-07-06 21:40

I have a Bobcat 753 at just over 1000 hours that has a tilt valve bonnet (part #7101345) that has failed, breaking into three pieces. Everything under the cap is tight. What might cause this to fail? I don’t want to replace it if the new one will fail.

    only ones ive ever seen broken were either loose, or filled with mud/water/debris
