BUFFER, RUBBER

551 950 90 BUFFER, RUBBER is essentially a shock absorber for specific movements on the rig. Think of it like a bumper that takes the edge off when something hits its travel limit, or when components need a bit of dampening to prevent metal-on-metal wear and tear. It keeps things from slamming too hard, protecting more expensive parts from impact stress and vibration, which is crucial for the longevity of the whole assembly.

When these buffers start to give up, you'll usually notice it. A common sign is an increase in impact noise – a sharper 'clunk' or 'bang' where there used to be a softer thud. Sometimes, you might even see components over-travel slightly, or feel excessive vibration in the structure around where the buffer is supposed to be working. It just won't absorb the energy like it should, leading to accelerated wear on adjacent parts and potentially misalignment.

Replacing these isn't usually a big job, but don't just yank the old one out and slap a new one in. Always take a good look at the mounting points and any associated hardware; sometimes the bolts or brackets get bent or fatigued from the repeated impacts the buffer was supposed to absorb. A quick check of those surrounding areas can save you a headache down the road, preventing premature failure of the new buffer or other components.
