Fast shipping

I ordered this part hoping it would arrive within 2 weeks because I had an emergency situation with an employee waiting to repair a piece of equipment at a customer’s location. The part actually arrived halfway across the country in 5 days including the weekend. MRO processed, packaged and shipped it with incredible speed. Thanks again!

Shaft output is reversible

Description should say that shaft is reversible. Other than that perfect fit. Good communication from the shipping folks.

When will I be charged for my order?
