Description
Overview:
The Clamping Ring UN9318-8 is a genuine Stihl fastener for securing components inside compact lawn mowers such as the RMA 235.0 and RME 235.0. It is a precision-formed metal ring designed to hold parts firmly on a shaft or within a housing, helping the mower run smoothly and reliably. Built for repeated use, it resists wear from vibration and everyday mowing. Supplied to Stihl specification under reference 9991 003 0648, this OEM ring maintains correct fit and alignment across compatible cordless and electric models. If your mower shows looseness in a wheel, axle, height adjuster, or deck-mounted assembly, replacing a worn or missing clamping ring is a simple, effective repair that restores performance and extends service life.
