BestautoMercruiser Alpha Bravo Alignment Bearing Puller Seal Bellow Expander Tools

i had my boat since 1989 new...this is the first time i replaced the gimbal bearing. it was about welded in there, wow...good thing i always keep my 19 foot bayliner Cuddy in the garage..otherwise i doubt that bearing would of been able to come out after all these years. as i tightened the removal tool there was immense pressure building up and then a loud crack and she broke free...after that loud crack the device began turning easily and soon had the bearing pulled out; to my relief. that loud crack was very alarming to say the least. the installation was effortless in comparison. just make sure you align that grease hole on the right side of the bearing, with the inlet grease tube on the right side of the outdrive housing. tap and pound it in slowly and check for alignment as you go is all. strong sturdy excellently built tool..worth every dime.

the puller works great and is easy to use. The alignment tool must be drilled in order for the bearing installer to go on and lock in place. It is best to do with a drill press. It is not pre drilled due to each application having the possibility of needing the installer at different lengths.

The puller worked flawlessly on pulling my gimbal bearing out of my OMC cobra. The alignment shaft worked well also but the drilling of the hole was a bit of a pain. I get why you have to drill your own hole because of it being a universal tool and is made for use on different systems. I used “O” rings on mine to assist me in locating the spot to drill my hole. I just put them on the shaft and pushed it into the coupler and the o rings slid up and gave me the location for the hole to be drilled. The alignment tool was a little big in diameter for my bearing so I took of .02 in my lathe. Overall a good purchase for the price.

For the most park I like everything but the gimble alignment tool it needs to be better machined because it is not a perfect fit.

I edited my response after trying to use the tool to reinstall the bearing. First of all, there are ZERO instructions. I had to find instructions on competing tools to figure out how to put this together to remove the bearing. That's where my one star comes from, it removed the bearing nicely. But that's the only thing it did well.When it was time to reinstall, I once again had to search other places for ideas on how to use this. The black ring with a bolt through it seems to be for reinstallation, but there's no hole in the alignment tool for the ring. And the ring will slide all the way up, making it useless, unless you drill a hole through a 2 inch solid rod.....Then I tried using it to align the motor. It won't do that either! The alignment tool is to big to get past the bearing, leaving a 3 inch gap between the tool and the motor.Save your money, rent a slide hammer from your auto parts store for removal. This tool is WAY over priced for the extremely limited applications where it actually worked.

Great set, actually has more tools than needed for an OMC Cobra. I bought it specifically to pull and install the gimbal bearing, which it worked as advertised. But the alignment shaft is too big for the gimbal bearing so it will not work as an alignment tool; just dropped it off at the machine shop with the old bearing. Not sure if it's bad machining or just bad advertising, either way not sure what this actually fits.

Worked perfectly. Saved a ton doing it myself.

All the reviews were horrible on these tools on every one I could find. I gave it a shot and the puller worked perfect. Everybody in the reviews said the size of the shaft was wrong to fit the gimbal bearing. Mine didn’t seem to fit at first but I realized it was actually a perfect slip fit. Application was a 2005 Mercruiser Alpha One Gen 2 outdrive. Worked perfect.

Every specialty tool you need for a full seal rebuild on a Alpha one. The only additional item that is required to set the bearing preload is aninch lb torque wrench from zero to 20 inlbs. This Alpha one setting is typically 5-8 inlbs. This is also available on Amazon

This tool cannot be used for its intended purpose without doing work on it. The first thing you have to do is take the bearing Drive plate and sand the paint out of the hole in the centre of it. Then take the main shaft of the tool and sand it or turn it on a lathe so that the bearing drive plate slides onto it easily and that it fits through your gimbal bearing. Remember the whole purpose of the tool is that it has to slide through the Gimbal bearing easily to align the cuppler and engine. Then you can drill the hole through the main shaft to attach the bearing drive plate. allow at least an hour if you have a well-equipped shop to re-engineer the tool so that it will work before starting to use it.The Bellows retainer is too small for the drive bellows and you have to remove your reverse lock to get it into the exhaust Bellows so it’s really not much use. It can be used but you have to do a considerable amount of work. I personally don’t think I should have to work on a tool especially one price in $100 range. The problem is there’s very little choice of alignment tools that do work on Amazon.

Do not buy this product, incredibly poorly manufactured, The bearing will not fit over the shaft And will get stuck if you try. It was also not useable as is because it was missing a hole that should be drilled through the shaft to let you use the installation disk for the bearing, which comes with the kit and has a bolt that needs to pass through the shaft.Absolute garbage, I don’t know how this is even being sold

Bar fit the splines good. had to file off some machining burrs and enlarge the seal driver bore a couple thousandths. You do have to drill a hole for the bearing driver bolt. Took a few minutes but well worth the cheap price.

I tried other pullers with slide hammers..... don't waste your time get this and your bearing will be out in a matter of minutes.
