Preparation: The shafts were first cleaned thoroughly using a solvent to remove any contaminants. A release agent (UPS Release Agent) was then applied to areas not intended for bonding.
Surface Preparation: Handheld grinders were utilised to remove any loose steel sections and to prepare the surface of the key seat, creating a coarse profile that would enhance the adhesion of the repair paste.
Application of UPS 105 EG THISTLEBOND METAL REPAIR PASTE:
- UPS 105 EG was applied to the voids in the keyway area.
- The shaft was then carefully inserted into the key seat, ensuring a precise fit.
- Excess material was removed, and the assembly was allowed to cure, forming a strong and durable bond.
