"Anyone help? 1987 Bayliner Ca

"Anyone help? 1987 Bayliner Capri. 2.3 OMC Cobra. Motor was knocking "bad rod bearing" removed the outdrive to pull out motor. The outdrive came out no problem. Took all of 5 minutes. Removed the motor, replaced rod bearings and reinstalled. Used the alignment tool and aligned the motor. Went to put the outdrive back on and it just will not go in!! It gets as far as the outter most ujoint houseing and makes contact with the u-joint bellow and will not go in past that point. I've done everything according to the manual for reinstallation. It's not making contact yet with the flywheel"spline" receiver on the motor, so I don't think that's the issue. It's as if the rubber bellow "shrunk" and isn't big enough to get that knuckle thru."

been there....luckily I had Caterpillar 1u9891 hydraulic oil additive....slipperiest stuff around....the problem is that the bellows swell and the ujoint hub part barely goes through it. if you find a long screwdriver and make sure there are no burrs on it, you can slide it through the ujoint and crank it back and forth whilst pushing"
 
"Well sounds like I may be on

"Well sounds like I may be on the right track then. But what a killer. I've been using wd40 mixed with marine grease. But, wasn't sure if that was really the issue since it came out so easy. Guess i'll just keep pushing and turning. Anyone else have any suggestions? Any idea why it swelled in a matter of 1 day since I removed the outdrive?"

"You may want to consider replacing the bellows, I've heard that the new ones are actually larger which makes it easier to get the u-joints through, how long since the bellows was replaced?"

"I really don't know the age of the bellow. I just recently bought the boat and it's an 87. So as far as I know they could be original. But, they are in great shape. Still soft and plyable no tears or holes. I'm wondering though how new ones could be bigger when they slip and line up right in the metal housing of the upper. It's the metal portion that would have to be bigger to allow more room."

"Most guys seem to have problems with the u-joints and yokes hitting the ridges on the bellows as they go through, still pretty sure the newer ones were redesigned to make it roomier inside, not right at the opening though as you said."

the seal area at the aft end of the bellows is just a little thinner. (bigger on the inside) makes all the difference.

Had this same problem when I put mine back together last year. Finally wrestled it in. Later I asked my outdrive mechanic about this and he said he heats the bellows to make it more flexible for stabbing the drive. You might try putting a drop light in the bellows for awhile to warm it up.
 
"Thanks all!! Just had to figh

"Thanks all!! Just had to fight with it. The yolk has to be lined up perfectly for it to be forced thru. Didn't try heating it up, but can see how that will help.
Future referance for all. Yolk has to be square to insert. If it's cocked at all it will not fit, and you will kill yourself trying. Once I got it lined up and pushed it slipped right it."
