Ensure the utmost precision in your engine builds with the JIMS USA Model 930 T/C Torque Plates. Designed for professional technicians and engine builders, these essential tools accurately simulate cylinder head clamping forces during the critical boring and honing processes. By replicating operating stress conditions, they enable machinists to achieve perfectly round cylinder bores, which is crucial for maximizing engine performance and longevity.
Key Features
- Simulates Operating Stress: Precisely mimics the distortion caused by a torqued cylinder head, allowing for accurate cylinder machining.
- Enhanced Cylinder Geometry: Ensures perfectly round and straight cylinder walls, leading to superior piston ring sealing, reduced oil consumption, and increased horsepower.
- Professional-Grade Construction: Manufactured by JIMS USA, these torque plates are built for durability and consistent performance in a professional shop environment.
- Wide Bore Compatibility: Accommodates bore sizes from 4 inches to 4.060 inches, catering to both stock and oversized applications.
- Versatile Adaptability: Easily integrates with conventional boring bars and Sunnen-type honing machines.
- User-Friendly Design: Features laser-lettered markings for clear torquing sequence and is designed to eliminate the need for ring dowel removal in most applications.
Applications
The JIMS USA Model 930 T/C Torque Plates are indispensable for engine builders and mechanics performing critical machining on late-model aluminum cylinders. They are specifically engineered for Harley-Davidson Twin Cam engines, including 99-13 and 99-17 Twin Cam Screamin' Eagle models. Utilizing these torque plates during boring and honing is vital to counteract cylinder distortion, ensuring optimal piston-to-wall clearances and a robust, high-performing engine build. This precision prevents premature wear and maintains peak efficiency, making them an essential tool for any serious engine blueprinting or rebuilding project.
