This YS Engine YSG7075 pump insulator is an RC-scale replacement part intended for DZ70 pump assemblies. It serves as the interface between the pump housing and its mount, providing an insulating layer that helps isolate the pump from direct contact with the chassis or mounting plate.
As a spare, the insulator's role is primarily to maintain correct spacing and to reduce direct mechanical transmission between pump and frame. Install by positioning the insulator between the pump body and mounting surface, align mounting holes, and secure with the original fasteners. Verify flat mating surfaces and clean any residue before reinstalling to ensure a proper seal where the insulator meets the pump or mount.
Use this part when replacing worn pump mounts or when reassembling a DZ70 pump as part of routine maintenance or troubleshooting pump mounting issues. This article describes its role and practical installation tips for hobby-scale RC pump setups.
