I have the axle seals in hand for the FF20. The new fan should be here tomorrow. Hope it is going to fit! Now to figure out how I want to do all this. I will either have to move the engine forward some or drop the rear end for the fan replacement. Guess it depends on whether I can get the drive shaft off the hydro. I have the set screws loosened already, just hope the shaft hasn't 'grown' into the hub. Can't apply a lot of heat, but may be able to get some in there.
On the axle seals, I will probably have to drain the rear again. And hope the axle hubs come off easily.
Then there is the weather. May be mid morning before I can venture out to start all this.
I'll try to take lots of pics. I'm afraid to look to hard at the inside of the wheels, I'm seeing some issues there. Guess I'll find out how bad when I get them off. Wish me luck folks!
Edit: Seal # is 788049
