Application Situation

A Fan shaft had failed due to abrasion from the process, and the bearings had seized in service.

Application Method

The application was carried out in accordance with a modified version of Belzona Know-How System Leaflet MPT-2 for rebuilding damaged shafts using forming techniques. The area was prepared using a disk grinder to roughen the surface and to make a cross-hatching pattern on the surface. A coat of Belzona 9411 was applied to the inside of the formers, and the edges where material will be pushed out. Belzona 1111 was applied to the shaft and covered the entire area using a brush and the mixing spatula to apply the product. Also, the inside of the formers were covered and evenly spread. The formers were clamped to the shaft. Once Belzona 1111 had cured the former was removed.
