PROBLEM

Show/hide table

The main stator slot top wedges may wear over time due to micro-movement, and may become displaced on certain G3520H Generator Sets. The stator slot top wedges are used solely during the production build process and do not degrade performance when missing nor are required for continued satisfactory operation. However, there is a potential of small wedge particles exiting the generator air exhaust.
