1979 15 hp johnson gearcase

[monriverguy]

I have a 1979 15 johnson that i need to change the lower seals on. My question is can i just pull out the bearing housing ? what keeps the gears and propeller shaft in ? and how do i pull the bearing and seal housing out ? and if i can do this what is the right way to remove oil seals and put it all back together ?

Thanks to all for your great no-how.

2 screws and the propshaft bearing housing comes out.----Propshaft stays in.

Thanks racer. Does it come out easy or do i need a puller? And what is the best way to get the seals out ?

I always pressure test first (mouth blow into tube is enough to find leak w/soapy water spray), replace offending seal, and re-rest.

On fresh water motor they usually come out easy.----Try and rotate the housing so you can use a drift to bump it out.----It might be a good idea to weaken the seals with a Dremel to pop them out.

ok i got the seals and o ring on the way.. What holds in the prop shaft after i take out the bearing housing ?
