Re: my 280 volvo leg top box frozen on
Bill, I assume that the transmission and universal drive shaft are still all connected!
Captmello mentioned the bearing cross "C" clips to you!
Even if rusted, try your best to remove two opposing "C" clips so that two opposing bearing cross (ujoint) "caps" can be removed.
This will lead you to getting this thing apart.... been there/done this on customer's boats several times over the years! There is nothing fun about it! Each is a different adventure!
But it can be done!
Even if you must sacrifice the female yoke, one of us will certainly have a replacement yoke.
Once the transmission is out of your way, you can use some sort of chain affair that will allow a slide weight, or slide hammer effect on the yoke.
You will want to shock the yoke in the AFT direction......, and then drive it the other direction until it loosens up.
All of this is going to takes it's toll on the PDS (primary drive shaft) bearings. They are probably shot anyway from the water intrusion, and are items that you should be replacing.
If you've not seen the damage cause by failed PDSB's or universal drive shaft bearing crosses, you may want to take a peek. It is not pretty nor inexpensive to repair!
NOTE: I'd strongly encourage you to NOT attempt removing the four clamping collar bolts until you have this transmission off, on the bench, and in a fixture!
With the water intrusion that the bellows allowed, these four bolts are very likely rusted/corroded in both the clamping collar and the thread inserts of the transmission main gear case! (The 280 collar bolts end up being a wet area on many of these! )
If these are corroded, you may round out the hex heads! Now you're stuck using the first procedure anyway!
Even if you were to successfully remove the clamping collar, bearing box, main drive gear and universal shaft......, it actually gains you very little! You must still create a shocking/pulling force to get the yoke free from the PDS!
(I'd sooner see you sacrifice the drive shaft "female yoke" and keep this shaft/bearing/gear out of your way, clean and safe!)
Once the transmission is on the bench, you can now apply controlled heat to the collar and thread insert areas! If the bolts do not come out, you end up machining them out in order to save the clamping collar.
Been there/done that many times also!
Good luck.... I hope you get it!
