PIVOT PIN

614 570 29 PIVOT PIN is typically found anchoring a major articulating point on the rig, like a boom section or a feed cylinder mount. It's what takes the shear load and allows that smooth, controlled swing or pivot action. Essentially, it's the backbone for movement in a high-stress area, keeping things aligned while under significant operational forces.

When this pin starts to wear out, or the bushings around it give up, you'll definitely notice some slop. Usually, the first thing you hear is a clunking or banging, especially when you start or stop a boom swing, or when the feed cylinder extends and retracts under load. That excessive play can lead to misalignment, putting undue stress on other components, and eventually, things just won't track right. It's not just annoying; it's a sign that bigger problems are brewing.

Look, when you're replacing one of these, don't just pull the old pin and slide a new one in. You absolutely have to check the condition of the mating bushings. If the pin is worn, those bushings are almost certainly ovaled out or galled up too. Skipping that step means you'll be doing this job again a lot sooner than you want, and sometimes, people forget to clear out the grease passages before putting it all back together.
