PROBLEM

Show/hide table

The existing injector hold down clamp may not retain the injector properly on certain C175-20 Locomotive Engines. If the existing clamp fails it can/will cause combustion gas to escape into the injector sleeve.

The existing rear exhaust manifold heat shield comes in contact with the rear exhaust manifold bellow on certain C175-20 Locomotive Engines. If the existing heat shield is not reworked it can/will cause an exhaust leak.
