The oil slinger is made of pot metal.
I had bought the 130 in the fall, it had not moved for a few years and had lived outside.
The following spring I started it but it would not move, I gave it a few tries when it finally started to move, but there was a big 'pop' just before it started moving. Shortly after removing the tranny cover in the warm shop is when I realized that water had gotten in the tranny, froze solid and that is how I broke the slinger.
Boss Hog had sent me a replacement, but the tooth count was wrong, he sent me another one, and told me to keep the first one.
I kid you not, just yesterday, I saw that gear still hanging on the wall, I told my wife, somebody may need that someday.
Check your tooth count, if I have what you need, all it will cost you is the shipping.
It will be a big job, tractor split, cherry picker, and might as well change the seals bearings etc....
This is when it was back together.
Advice.....Take lots of photos during stripdown to make record of how it will go back together.
If you order your seals and bearings, have them on hand, you should be able able to do it in a couple days.
