The Wacker Neuson Battery J-Bolt.25-10 is a genuine OEM fastener designed for the RD27 tandem roller series, E1250 hydronic heater series, and HSH380S hydronic surface heater. As a direct factory replacement, part ensures the battery is secured exactly as intended — correct thread engagement, correct clamping load, and the right material spec for electrical connection integrity. This J-bolt fits across multiple RD27-100 and RD27-120 configurations including the Pro and Basic T4F variants, making it a widely applicable service part for fleets running Wacker Neuson compaction and heating equipment.
Key Features
- Correct Thread Specification: — .25-10 thread form matches the OEM battery terminal hardware exactly, ensuring full thread engagement without stripping or cross-threading during installation.
- Genuine OEM Source: — Manufactured to Wacker Neuson factory standards, this J-bolt maintains the proper clamping torque and electrical conductivity required at the battery connection point.
- Broad Fitment Across Two Equipment Families: — Confirmed fit for RD27-100 and RD27-120 tandem rollers (Pro and Basic T4F builds), plus E1250S and E1250P hydronic heaters and HSH380S hydronic surface heaters.
- Secure Battery Retention: — A correctly torqued J-bolt holds the battery firmly in place under vibration and travel loads, preventing terminal movement that can cause intermittent electrical faults or premature cable wear.
- Electrical System Safety: — A loose or undersized battery fastener can cause arcing, voltage drops, or unplanned shutdowns; using the correct OEM J-bolt protects both the electrical system and the operator.
- Direct Service Replacement: — Part number 5200002491 cross-references directly in Wacker Neuson parts documentation, making this a straightforward like-for-like swap during scheduled maintenance or battery service.
A battery J-bolt is the threaded fastener that clamps the battery hold-down bracket or terminal hardware securely against the battery body. Its role is to prevent the battery from shifting under the vibration and dynamic loads that compaction equipment and heating units experience during operation. When this fastener is missing, stripped, or under-torqued, the battery can move freely — leading to damaged terminals, broken cable lugs, and unreliable electrical supply to critical machine systems. Replacing a worn or lost J-bolt promptly is a low-cost step that protects the entire electrical circuit downstream.
