If you are simply replacing a factory mount, "preparing the piece" involves readying the workspace and the new part.
: The most critical step is cleaning. Use a heavy-duty degreaser to remove all oil and road grime so the urethane bonds correctly.
: Transfer the template to your metal stock. Drill the bolt holes first to ensure alignment before cutting the outer shape with a cutoff wheel or saw. motor*mount
: Deburr all edges and thoroughly clean the metal of grease and rust to ensure a clean surface for welding or painting. 2. Prepping an Existing Mount for Urethane Filling
: Many factory mounts have a metal heat or drip shield. You must remove these from the old mount and transfer them to the new one before installation. If you are simply replacing a factory mount,
: Use a jack with a wooden block to support the engine's weight. Never jack directly on the oil pan without wood, as it can rupture. 4. Preparing a Small DC Motor Mount (3D Printing)
For hobbyist electronics or robotics, "preparing" often means 3D modeling and slicing. : Transfer the template to your metal stock
: Completely seal one side of the mount using contact cement and multiple layers of duct tape to prevent the liquid urethane from leaking out during the pouring process. 3. Prepping for Standard Replacement
