Oil Leak B&S Model No. 44Q777,

Dave, Ty may be referring to an installation protector. Although spring load neoprene seals are long lasting they can be damaged during installation. A PTO? , a clutch input shaft, a drive axle, are typically splined and probably bigger OD than the dia of the installed seal. The normal installation force stretches the seal and the "sharp" splines can cut the seal so it leaks. A very common problem.

Some seals come with a plastic tube "protector" to placed over the spines. You lube the tube/seal and then slide the seal over the splines. Make your own protector by wrapping duct or insulation tape over the splines before installing the seal.

have you checked the breather assembly(valve cover) for obstruction?and did you use a seal protector when you replaced the seal?

Yes, checked it all when I replaced the seals and gaskets last year. I think it's time to put a dial indicator on the shaft and see if it moves.

All of the major engine makers use to have there own set of seal protectors as part of the dealer tool kit. but they are all been obsoleted out of the kit, and now they recommend the old microfiche cards for use as protectors. I guess they figure we might as well use them for something, other than taking up space. since all parts diagrams are now online.
