Seiko Oil Regulator Spring (Part #15059)
Complete your machine’s lubrication system overhaul with the Seiko Spring (Part #15059). This authentic tension spring is a precision-calibrated component designed specifically for the oil regulation assembly of the Seiko LSW long-arm series.
The regulator spring provides the critical counter-pressure required to hold the oil regulator shaft and dial in their precise positions. In high-vibration industrial environments, a weak or "tired" spring can lead to "creeping" adjustments, where your oil flow slowly changes during operation. This Seiko part ensures that once you set your oil flow, it stays exactly where you need it for consistent performance.
