U-joint bellows: installing the retention ring thingamajig
For the love of god, how does one slip this mofo in there? I went with an oem bellows and all else is well but I can’t even get the friggin thing started. Funny enough, YouTube usually has some redneck sitting on a bucket explaining things with a few helpful hints but every video I’ve found shows people ripping things apart but no one dares shows how it goes back together. Any tips or tricks are appreciated and my knuckles thank you. |
Lube it up with dish soap and push it in by hand. Or at least thats all I've ever had to do on the several Ive done. Have seen some take a 2x6 and cut it just a tad smaller in dia and use it as a driver. Make sure its seated in the groove
|
The bellows has a small bulge on the outside flange that has to fit into a groove in the helmet. IF you don't have it in the groove the ring won't go in.
|
I did slip it over the groove. I won’t make it back to until next week but I’ll give the dish soap a try. I did find that 3” ABS pipe with a coupler on it makes a great ring driver. The pipe fits inside and the coupler is the same size as the ring. |
merc rec power tune for the install and their correct install driver tool.

Its a Ford 351 oil filter if I recall correctly that works great for the install. |

Ayuh,...... Agreed,.... A quick squirt of Quicksilver Power Tune, 'n it'll slip in with finger pressure,..... Love the stuff,..... Makes rubber super slippery, 'n evaporates really fast, lockin' things together,..... |

proper oem tools is key. without them - one is making the job 100 times harder than it needs to be. I can not stress this enough and proper OEM service manuals per that engine / drive serial numbers is just as important.
Can one image for an off the cuff example hiring a AC tech to work on your home AC without any proper AC tools nor any AC service manuals per applications. Just an example to think about when working on boats and ones down time for proper installs. I am not finger pointing here but use this info as taking a 3 to 4 hour job not turning into weeks on end for basically not a hard install for one to overcome.. Next question is where did you buy the bellows and whos bellows are you trying to install ? BY far OEM Merc has the best bellows and impellers bare none. I would pay the extra money for the MERC branded bellows if they were not. Hopefully you did not buy this from EBAY ---- those are cheap junk and some do not fit properly if they did not come in a quicksilver / merc unopened bag / box. |
I did buy oem bellows from Nuwave. At least the package said quicksilver. I was able able to borrow some proper tools and this is still the most retarded engineering to deal with. I’m sure that there’s tips the pros use and experience is everything but even with the proper tools this thing is a nightmare for the amateur. |

On a side note, is there any reason not to use bellows adhesive? The one I pulled off showed zero evidence of any adhesive and slid right off with no prying. |
Adhesive
Well if you put the bellows on with no adhesive and no clamp. Run the drive up and the bellow easily comes off. A good clean surface both sides with correct adhesive will help keep it on if the clamp losened up over the season without it being checked. So since the engineers specked bellows adhesive I always use it. one trick is to take the helmet off and glueing and clamping that end on the bench. Then with clean mating surface clamp in place push the bellows on tighten clamp let glue set. Two mechanices working side by side one takes helmet off ones doesn’t to replace bellows. Wrench pulling helmet off usually wins time snd quality wise every time. |
hopefully everyone up here knows about that you have to clean / remove the mold release agents from all bellows before installing ? right ? If not hopefully possible some good info in this post. Also one has to completely clean the transom assembly flanges before all bellows installs. This helps the bellows against slipping off when trimming the drive. This info is even in the OEM service manuals. Hence why it is so important to own the proper oem service manuals. Hope this helps whomever.

I believe his problem was that He didn't have the bellows bead in the groove.

In the groove
Agreed taking off the helmet is best way to clean everything and to make sure you get both sides in the groove with bellows adhesive. :-) |
I made a Driver tool for the Bravo and Alpha G2 out of a piece of Aluminum . Also I use Silicone Spray for Lube on the bellows ring .

Funny thing is after it was all said and done I found the service manual for it that I bought first after buying the boat because you can’t do chit without the information, lol. A few things I had going against me; 1) The boat is remote, so I’d go after a long week of work and often was always missing that one tool back in the garage. 2) Fatigue. I’d been working on this pos all summer and felt like one step up and two steps back. 3) The biggest issue - too much Internet. I became reliant on the interwebs when it’s often idiots having the exact same trouble as me teaching me what I already was doing wrong. A few pointers for the next poor sap that finds this thread. 1) That little metal clip goes on the bottom of the bellows on the transom side. When the hose clamp is cinched it’s pushed into a groove so it doesn’t pop off when the drive is lifted. 2) The bellows has multiple applications and it is the second groove for the Bravos and first groove for the Alphas. The ring then slides in easily enough and when the drive is cinched in it holds everything in place. 3) only use oem bellows and senders or you will be doing this again in short order. The Merc sending units actually have good instructions for what I just described. 4) Your mating surfaces can not be too clean. The bellows I pulled off had no glue on it so that was easy, but I had to clean everything up after redoing the helmet connection. Good luck! |
Doing something for the first time even with instructions can be problematic at best.
I am glad you got it figured out and fixed. I spend a LOT of time just looking at stuff to try to make it work better. |
I just changed my bellows on Bravo this past weekend and the 2X6 workd like a charm....slipped right in place! Love the redneck sitting on a bucket comment though!! LMAO>>>
|
If you are only changing the u-joint bellows is it necessary to remove the gimbal helmet?
|
No but once you do it by taking off the helmet off you will always do it that way! |
