When I purchased the 990 a couple years ago It came with a second one for parts or repair. I inspected the frame on that one today. That frame is also cracked but not as bad, just the bottom side of the hole.
That’s good news Keith when you get a chance post a few pics of your tractor. I noticed a White in your avatar. I have a 1855 that I have dismantled. I had to slide the engine forward to replace a hydro fan. I noticed a lot of surface rust underneath because of it sitting so long outside before I bought it so I just decided to dismantle the whole thing, clean it up, sand blast, prime and paint. The 1855 and my 990 are my favorites that I have.
The white was a 960, manual shift. I really liked that tractor, pulled like crazy, hauled out a lot of wood with that one. I still have it but the clutch gave out. so I bought the 990 for ease of operation in the wood lot, don't have to push clutch and shift. I will post a picture, should have it up later today.
I have to replace hydro fan on my other tractor, where did you get yours?
All ready to go back for more logs.
On eBay for about $25.
