Troubleshooting & Maintenance FAQ

1. Why is my 352.3*48T Coupling vibrating excessively during operation?

Excessive vibration in the 352.3*48T (352348T) often indicates spline wear or misalignment between the engine and the pump. If left unaddressed, this leads to shaft damage. We recommend a full inspection of the rubber or nylon elements and replacing with an OEM standard coupling to restore balance.

2. How can I tell if the 352348T Coupling has failed inside the bell housing?

Common symptoms include a sudden loss of hydraulic power despite the engine running, or a high-pitched grinding noise. Upon inspection, if you find black dust or melted fragments, the coupling has reached its wear limit and needs immediate replacement to prevent engine stall.
