OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Getting Blade boss Off

Hi All, Well, flushed with success from the repair of a trimmer (helped here a lot), I foolishly bought an old mower from the tip for a repair project. It is a Victa with a 3.5 HP briggs and stratton classic model: 9D902 Type: 2091 B1 and Code: 05110351. I suspect it has serious engine damage as there was no compression and a lot of metal shavings around the carby (did'nt see that until I got home!). Anyway, I have started to pull it apart. The piston and valves move up and down and I can't see any scoring on the cylinder wall. I am stumped at the blade boss. I think it is a tapered shaft as I can see a pin in it but a search on these forums does'nt say which way it should be knocked off (up-towards the top of the mower or down). Does anyone know how I should go about it. The blade holder bolted into the end of the boss. Here are some photo's:





As always I am grateful for help....
