Forgive me,I posted about this a week or 2 ago and coudnt find it for the life of me.
But just had a few questions about what to expect if I try to do this. First off ,I read a few different places and seen both answers but I was told do Not shift the gear in forward to remove the B3 drive you leave it in neautral,True-False?
So next step they say B3 is Very Heavy and should not try to take it off even with a buddy. They said use a engine lifter and there is a hole on the outdrive where you can clip something on it and lift it with a cable or something.Is this what I should do,or do you think me and my friend can lift it and just prop it up on something to keep it upright. Any harm if I just lay it on its side in my garage on a blanket or something?
My next question is when I pull this, the drive shaft should just pull right out and I can work on the Ujoint from there. But replacing the gimbal bearing am I going to be able to get to it with just the outdrive removed, Or is the Gimbal Ring and bellows going to have to be removed also?
I tried looking Youtube and seen a few vids but they were doing bellows and already had it tore down all the way,I wasnt sure if you actually needed to do all that just for the bearing?
 
Thanks,That will come in handy.
I just ran into this vid,they dont replace the gimbal but they show how to remove the outdrive.

I have a few questions about that, One he said he greases the gimbal bearing from up top? I never seen a grease fitting on my outdrive? Is there some way to grease the gimbal from engine bay or something?
Also when he has the outdrive off he cleans the one end of the driveshaft off and lubes it,but he leaves the other end in the outdrive,Wouldn't that side just slide out just as easy and need lubed and cleaned as well?
 
I would read the manual for those answers. only the input side needs grease, the other end is held in place by the gear assembly.bearing that can be greased have a fitting on the right side of the transm assembly. newer bearings are not greasable.
 
Can one person do it? Yes. But do not mistake that for me saying it is light. It is not. Take the props off - it'll help.

Rather than laying it down, then having to move it a few times, make this:

Lazy Daze,Even I can make one of those :grin: Thanks for that!
I see in your pic the driveshaft is still hanging out of the drive on the stand,The drive shaft just pulls out right?
