Last thing I heard is that you can't get a rebuild kit for them anymore so I checked and it looks like you can get them for around $100. Although on the Allis 416 you should be able to bypass the fuel pump and run it straight to the carb.
If we don't use the fuel pump, the we'll have to keep at least a third of the tank with gas so it will run.
Sorry I wasn't there to root you on when you were trying to get the deck freed. I was looking at the pics and it looks like you may be using some kind of under bearing puller to get the lower bearing off after you drive the mandrel's apart.
This may be a late fall project on the deck as I may not have time to tackle it before then!
