A gearbox

 
 

Problem:

Substrate:

Mild Steel

 
 

Application Method:

Application was carried out in accordance with a modified version of Belzona Know-How System Leaflet ENC-1. The gearbox was first grit blasted, then a two coat system of Belzona 5892 was applied to the internal areas.

 
 

Belzona Facts:

The Belzona solution was a surefire way of fixing the problem. It was also found to be more cost effective, quicker and safer than traditional weld repairs.
