I would use one of these given the size of the seals. Drill a small pilot hole, and thread this in ever so slightly, Phillips would be recommended.
and you will only need one.
So do you need 2 15x25.5x7 seals?
I have to do my crank seals because one is leaking. I checked with some propane on the stator side yesterday so this is fresh in my mind.
At idle I can put propane right into the air filter and the moped bogs. When I took the cover off the flywheel and shot the propane on top of the flywheel, nothing happened. Then I revved the motor and the motor would just about kill as the rev's dropped back down to idle. It would not want to die if I wasn't holding the propane nozzle right there. I think it is true that these old seals can leak - Not at idle, but during load. DOH I just noticed I forgot to check the vario side.
I have to make a clutch puller to do the vario.
