I have a B&S 8hp 193707 that has a leaking oil pan gasket. I have pulled it down to replace the gasket and the oil seal.
Unfortunately when I was putting it back together the timing gear wasn't seated back properly on the crank shaft and the timing gear broke as I was tightening the oil pan bolts.
The new timing gear arrived today but it is a very tight fit on the crankshaft and the key does not slide easily through the slot on the inside of the timing gear. I need some advice on how best to slide the timing gear back on the crankshaft and align it with the key.
I thought firstly that I could gently file and widen the key slot on the inside of the timing gear to allow the key to slide in snuggly then use something to tap the gear gently down the shaft until it locks in place with the key.
I am worried that if I get the gear half way down the shaft that I might get it to a position where I can't go forward or backward back up the shaft because it was so tight.
Any help or suggestion would be appreciated.
