REPAIR SET

REPAIR SET 3115 1436 90 is what you're reaching for when you're tearing down a hydraulic cylinder, maybe a feed or boom cylinder, or even getting into the guts of a rock drill. It's the collection of seals, O-rings, and sometimes the odd wear ring or bushing that keeps everything sealed up tight and moving right. Without these bits, you'd have oil bypassing, pressure dropping, and metal wearing out way too fast. It’s all about maintaining that internal integrity so the system can actually do its job, whether it's extending a boom or delivering percussion.

When these components start to wear out, you'll definitely notice things aren't quite right. For a hydraulic cylinder, you might see it start to drift or sag when it's supposed to be holding position, or you’ll get external leaks if the rod seals are shot. If it's inside a rock drill, you'll often see a noticeable drop in percussion power, or the drill might start to bind up. Sometimes you’ll even hear a sort of groaning or chattering noise as internal bypass issues develop, which means the oil isn't being directed efficiently anymore.

When you're putting this kit in, take your time. Always give everything a good, thorough cleaning, especially the grooves where the new seals sit. A common mistake I see is folks forgetting to properly lubricate the new seals and wear rings with clean hydraulic oil or grease before assembly; a dry seal is just asking for trouble and can tear on installation. Also, always double-check the mating surfaces – if there's any scoring or burrs on the cylinder barrel or piston rod, those new seals won't last long.
