Well, I decided I would probably use this 317, instead of trying to get the other one back in shape. I don't need 2 of them, but one will provide a good source of parts for the other.
I hauled it to a car wash and cleaned it off as best I could--there was crusted on oily dirt everywhere underneath. In the process, I managed to break the clear line that shows the transaxle oil level--it was pretty brittle, and needed to be replaced.
The body pan was only held on by two bolts, so I decided to remove it so I could more easily work on the transaxle, etc.
When I got the body off, I discovered this:
I've never known of a metal fan to break like this unless it's physically damaged. The broken-off blade was lying in the bottom of the fan shroud--completely buried in crud...
Now, a couple questions:
How do you remove the fan??? this one had a nylon wire tie through the hole up by the pump, I removed it, but the fan hub seems to be pressed on.
How do you drain the transaxle. There's a big hex nut at the very back, about even with the axles, but it wouldn't drain much from that... do you break a line free?
As always, any help would be appreciated.
