Snow blower impeller modification kit, 3 blade universal for converting 2 stage machines. Designed to reduce the gap between the impeller and the impeller chamber wall, this kit improves operating efficiency and snow throwing performance while reducing the chance of clogging. Key benefits Improves conversion rate and snow ejection by minimizing the clearance between the impeller and the chamber wall. Reduces snow accumulation and clogging in heavy or wet conditions. Durable construction for long service life and reliable performance. Easy replacement of worn or damaged impeller components to restore machine function. Features Function: Lowers the clearance between impeller and impeller chamber wall to increase efficiency and throwing ability and to reduce clogging. Material: rubber metal material that resists breakage and wear. Design: Universal 3 blade configuration for modifying 2 stage snow blowers. Quality: Professionally manufactured for stable performance and long service life. Specifications Material: Rubber Metal Sizes: 12.5 cm x 4.83 cm (4.92 inch x 1.90 inch); thickness 3/8 inch 9.4 cm x 3.3 cm (3.7 inch x 1.3 inch) Package contents: 1 set Snow Blower Impeller Modification Kit Note: Allow slight measurement differences of 12 cm or 0.390.79 inch due to manual measurement. Compatibility and replacement Universal design intended for 2 stage snow blower models when converting to a 3 blade impeller setup. Use this kit to old, damaged, or broken impeller modification components to restore machine efficiency. Practical use scenarios After a season of heavy use, worn impeller parts to reduce clogging and regain consistent snow ejection. When clearing wet, heavy snow that tends to pack in the impeller housing, install this kit to shrink clearance and improve throwing performance. For workshops servicing multiple 2 stage units, keep this kit on hand to quickly convert or machines during peak winter demand. Installation and care Inspect the impeller chamber and confirm sizing before installation. Follow the machine manufacturer recommendations for disassembly and reassembly. Check fit and clearance after installation and test the machine briefly to confirm proper operation. Store spare kit components in a dry place to preserve rubber metal condition. This kit provides a practical, durable solution for improving the performance of compatible 2 stage snow blowers by reducing clearance and minimizing clogging risk.
