SPI SM-03108 Chaincase Gasket for Polaris

Chaincase Seal

The SPI SM-03108 Chaincase Gasket is a replacement sealing component designed for compatible Polaris chaincase applications. It helps restore the sealing surface between the chaincase cover and housing, supporting proper retention of chaincase lubricant and helping prevent leaks caused by a worn, damaged, or removed gasket. This component is supplied as one gasket and is identified by SPI part number SM-03108.
Use this gasket when servicing the chaincase, replacing internal components, or completing routine maintenance that requires removal of the original cover. Installing a new gasket during reassembly can help promote a dependable seal and reduce the risk of seepage around the mating surfaces. Before installation, remove residual gasket material, clean and dry the contact surfaces, and verify that the replacement gasket matches the application and cover profile.
The SPI SM-03108 is intended for powersports repair and maintenance use where a compatible Polaris chaincase gasket is required. Always compare the part number with the service manual and the original component before installation, as model-year and application requirements may vary. Follow the manufacturer’s recommended procedures for sealant use, fastener tightening, lubricant selection, and final inspection. Proper installation helps support reliable chaincase operation and protects surrounding components from lubricant contamination.
