Briggs & stratton Vanguard crankshaft play

george56 · 10-05-2009, 11:37 AM

I have a Briggs & straton 16 hp vanguard vertical shaft engine model 303777 type0411-01. The flywheel is hitting on the mounting screws of the alternator and oil is leaking from the oil seal on the magnito side of the crankshaft. The crank will move up and down about aqn 1/8 of an inch. I presume the crank shouldn,t have this play which seems to be the cause of these problems. I also have got some gas in the oil. can you help

Update to crankshaft play. I removed the sump or crankcase cover. There is a small ridge on the cover where the timing gear on the crank comes in contact with the cover. I ,m assuming this is a wear spot causing my problems. Shuold this surface be flat? the ridge is about 1/16".
