Briggs 243431 Engine Seal help

Recommended Posts

Buickgsman
Hello everyone, I've been away for a while but I started getting the landlord 243431 engine back together today. I cracked open the gasket kit(pn 299101) that I got from Jacks and found only one seal in the kit. It had the PTO side cover seal, the rubber crank seal, but no seal for the small cover under the flywheel. Does anyone know what the deal is about this seal? I found a picture of this kit online and it only shows just the one seal. Should there be another seal or should I have to purchase something else to seal up the motor? Thanks! Bob

You need B&S part # 391086S. It would appear that its listed with the gasket set. For some reason they refer to it as a "gear reduction" seal. Maybe that is the primary application for the seal on some other engine.
