## Product's reviews:
- Spur gear - Our Yellow Karcher "Duckee" steers once more.
The spur gear works as advertised!!!
- Perfect - Perfect replacement part, Good purchase experience. I would use MRO again.
- Flexible coupler - Very fast and reliable shipping.
- 21 tooth 12 dp spur gear - The 21 tooth 12 DP gear I bought arrived very quickly.
It was exactly what I needed to fix my RV slide out.
I had to machine it to fit, but I knew that when I ordered it.
VERY SATISFIED!!!
