Technical Notes

The S4DS-011 core assembly features a central cast housing with machined metallic flanges and threaded fasteners. Visible turbine and compressor wheels have curved blades arranged symmetrically around the shaft. Buyers should inspect the bearing housing oil feed and return ports for blockages or corrosion before installation. Check for foreign object damage (FOD) such as metal shavings in the old unit's oil lines; a system clean is recommended if debris is present to protect the new core.
