I have a 1996 Sundancer, with 454's V dirves. After changing the dripless seal on the port drive, durring reassembly of the coupler, the seal on the Hurth HSW 630 transmission started dripping. This is very strange because the shaft was not completely pushed foward! I understand the boat must be back in the water to check alignment! I have the tranny coupler removed but at this point I am not sure how to remove the seal from the out put shaft. It is a press fit, I was told it can be done without pulling the motor and disassembling the complete transmission! One diagram stated after removing the transmission the seal can be knocked out with a flat tip punch. The only way I see to get out is to completely destroy it! My thought is to see if I can attach some self tapping screws to the seal, then attach some type of puller to remove the seal. Anyone ever done this repair without removing the tranny?
I just did this exact same job. Are you talking about the seal behind the flange on the transmission? If so you may have damaged it while trying to hold the 11/16" nuts. If that is the seal that is leaking ,you will have to pull the trans flange and pry the seal out for replacemant. I have a 37. there is about 10" of room to do that type of work.
if you go to a Napa they will have an inexpensive hook type seal puller, be sure not to gouge the alumnim where the seal presses in,forget about doing the aft seal if ever needed. these seals always leaked not just from damaging, make sure the surface is clean of any oil and do not put a sealer on the outside of the seal, if needed have the surface of the coupling polished where the seal rides
No that is not true you have a Sea Water Pump with either a hose coming from the outdrive or a sea water pickup and a Water Pump mounted on the engine. The sea water pump has an impeller that should...
