PROBLEM

Show/hide table

The existing clamp used to secure the air intake hose to the turbo inlet may be incorrectly positioned on certain 226B3 Skid Steer Loaders. The air intake hose may slide off the turbo inlet during operation, allowing dirt ingestion and causing severe engine damage. The clamp needs to be positioned correctly in order to prevent the hose from sliding off.
