Thank you.

Thanks Rick I appreciate the info. My JD dealer wanted to sell me a complete rebuild so I wasn't going to ask him for the info. Hope I am not the idiot for just replacing what I did.

JD has a great reputation to protect, so sometimes they do a bit of overkill to protect the reputation. Gotta respect that, but it gets pretty pricey.


If you need anything else let me know. I'll help however I can.


Thank you for the accept, and best of success!
