Today, the throttle body or EA arrived at my home. Inspected the rebuilt parts along with the defective parts that were replaced, the old wire harness was very fragile with open wires, torn insulation, etc. The other two defective parts including the gear and the clutch, I cannot see why they were replaced. Maybe bent, worn out, etc. Maybe the repair technician did some tests on the old clutch and gear (as shown in the pictures on this thread) and found out to be defective. I was impressed with the EA, very cleaned on top, bottom and all four sides of the EA and brand new wire harness on the EA. I am looking forward to complete the job I was set out to do in the first place.
