Re: Main furling motor and gear on 54

Hi guys, 
I am leaving it overnight soaking in diesel. I tried a puller earlier to push out the shaft but nada.
Tomorrow I will apply heat and the puller. If that fails I guess it will need a press.
I just wonder why it is not a nice snug fit, not as if it is a ball of rust. Maybe if when it finally yields it does not go back in with a gentle tap, I will have it machines down a next timeI can pull it easy as kiss my hand.
Slightly fed up with a day of poor progress.

Best of luck,

I know this has come up before, but I am servicing the main sail furling motor and worm drive.
It is all well but the top shaft seal should be replaced.
Shaft into the worm gear is very tight. Soaked it in diesel for some hours, hesitant to hit it. Plan to find a press to press it out.
Does anyone have a better idea?
