Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications, ensuring the stopper functions correctly within the generator's mechanical assembly without compromise.
• Direct-Fit Replacement — Engineered to seat and secure exactly as the original, with no trimming, shimming, or adaptation needed during installation.
• Broad DCA-Series Compatibility — Fits DCA20SPXU4F, DCA20SPXU2, DCA25SSIU4F, DCA25SSIU3, DCA25SSIU4FC8, and DCA25SSIU4FC8 60Hz generator models, including Servpro-designated units.
• Maintains Mechanical Integrity — A correctly installed stopper limits unwanted movement of internal components, preventing wear, misalignment, or damage to adjacent parts during operation.
• OEM Part Number Assurance — Part number this part matches Multiquip's official parts documentation, eliminating guesswork when cross-referencing your generator's service manual.

A stopper is a mechanical limiting component that restricts the travel or movement of an internal part to a defined range, preventing over-extension, contact with adjacent components, or structural stress during operation. In a diesel generator like the DCA-series, stoppers are typically found in linkage, panel, or enclosure assemblies where controlled movement is critical to reliable function. When a stopper becomes worn, cracked, or missing, the component it governs can shift beyond its intended range, leading to accelerated wear on surrounding parts or an inability to secure the assembly in its correct operating position.
