Gimble bearing grease mistake!

I think I may have made a mistake on my outdrive. I was recently greasing connections and used a white synthetic grease on the gimble bearing. After more reasearch (after the fact) I believe this was the incorrect grease for the joint. Question is, what should I do now?<br /><br />I now know that certain greases can cause damage to this critical bearing. Do I need to drop the drive, clean it and re-pack the gimble to prevent damage?

Re: Gimble bearing grease mistake!

Do you know how to remove and reinstall a gimble?

Re: Gimble bearing grease mistake!

I don't know that I would try to actually remove the gimble because I know you then have to replace the bearing. I was going to try to purge and then clean the old grease. I might be able to flush with WD-40, blow clean with air, and then re-pack.<br /><br />Looking for help. While I have not done this before - I have a factory service manual.

Re: Gimble bearing grease mistake!

You have to take the outdrive off to do this. I quess you could try to clean it without removing. I would use carb cleaner. It has good pressure out of the can and you get the little red nozzle to work with because you can't get real close to it cause of the bell and bellows in the way. I would try that first. Get new gasket for the outdrive. The hard part is getting the OD back on be sure to get your shift rods lined up right.

Re: Gimble bearing grease mistake!

The gimbal bearing is a sealed bearing and even if you did remove it, you couldn't clean it out. Leave well enough alone and use it. The difference in grease probably won't hurt it and even if it did start making some noise down the road, just replace it out at that time. Over the years I've seen just about everything pumped into these bearing. Just remember, any grease is better than no grease.

If you want to real tech. The bearing can be punched out from the carrier and cleaned. Then, you might be able to clean the carrier as is and regrease and punch the bearing back in. I dought he has the tools to remove the entire gimble and replace it. Think there's an illustration of the bearing removal on post here.

To Captain Ken,<br /><br />Txboatboy feels he needs to do something. Have you ever had your boating day absolutely ruined worring about something like this. Afterall you're on the water. He would get good experience taking the outdrive off and putting it back on. No special tools and the gasket doesn't cost much. Of coarse if his drive shaft is bound up, he's opened a can of worms that needs to be opened. With all due respect Captain Ken

Re: Gimble bearing grease mistake!

No offense Fatback, but that bearing is a shielded bearing. That means that even if you knock it out of the carrier, you still can't get into it. If you remove the shields, then you defeat the purpose of the shields. If the shields are pried out, they can't be reinstalled. Without the shields, the bearing will sling the grease out and will self destruct. Removing the outdrive will serve no purpose unless he is ready to replace the bearing. So unless Txboatboy has a bearing remover and an alignment tool, he's better off leaving well enough alone. All of us has had a day of boating ruined by a foolish mistake but there's no need in making it worse.

To Captain Ken, <br /><br />OK I relent, you are right! If he managed to get the bearing back into the carrier and not mess around anymore than that with the carrier, other than to try to clean it,he might be releaved. In all probability , if the grease makes his gimble go bad, he'll hear it singing and get back to port OK. But, until then,if he played with it to the degree I'm suggesting, he wouldn't worry and he will have learned something. If he's like me,he wouldn't take our word to leave it alone. With all due respect--and I mean it --Captain Ken

Re: Gimble bearing grease mistake!

just curious why not shoot that bearing with the right grease! It must have been packed with it before you added the white grease.

Been there!Done that!White grease,green grease,synth. grease.I have never had a problem with my gimbal.3 different boats and not 1 problem.Grease before you go into the water and after you take the boat out of the water.If you are a fanatic like me you can attach a hose to your grease gun and grease it when it is in the water.As long as your bellows is not leaking water you should be fine."Remind Spanky to Grease Wheezer"

If it was me. I would start the motor (so things are spinning) and start pumping away at the grease gun. About 20 stokes should pump out the white grease.

Re: Gimble bearing grease mistake!

You guys need more important crap to worry about...you could NOT find a grease that would wreck this bearing...jeese..the only reason they ever die is because water gets in them and they rust...<br /> rule 1...if it moves, grease it.<br /> rule 2...if it dont, paint it.<br /> rule 3...ANY grease is better than NO grease.<br /> rule 4...if you have more different types of grease in your garage than different types of beer in your fridge, you need to re-evaluate your priorities...

Re: Gimble bearing grease mistake!

Now you got me riled up!!! If the flashpoint of that grase is low what's gonna happen if it doesn't lube right and gets hot? Like the dumb grease I put on a wheelbearing when I was 16. Welcome to the Forum Txboatboy.

Re: Gimble bearing grease mistake!

Actually, there are many warnings from the manufacturer on using grease with solids such as Teflon. The solids accumulate in the roller bearing and cause the rollers to slide versus roll (so says Mercruiser). The grease I used was the Penzoil synthetic grease that does not state that it has Teflon in it.<br /><br />My plan is to drop the drive and manually spin the gimble bearing while pumping in the new grease. It will push out of the shielding and purge the white grease. As someone pointed out before, this is a '99 year model boat and I am not sure that it has ever been apart. Probably a good preventative maintenance function, however, I am not sure the white grease would hurt anything either. Better to check than find out in the middle of the bay....

Re: Gimble bearing grease mistake!

I use some white synthetic grease, pennzoil I think, that I buy at Wal-Mart. I use it for most everything short of wheel bearings. It goes in my I/O's Gimball (I think, I would have to check since I haven't touched it in a few months), steering, tilt/trim joints, alamites, etc. It also goes in my outboard's steering, tilt, etc. I even smear a bit on the prop shaft when putting a prop on. I haven't had any problems with ANYTHING. Is it the perfect grease for all those items, NO. Does it work just fine for me, YES. Granted, I hit each accessible grease point with a couple pumps of grease each time or two the boats are used. Grease is cheap. I can do this all summer on less than $5 in grease. Same thing with wheel bearings. I think I did put heavier grease in the u-joints. <br /><br />Bottom line, I wouldn't get too upset over that Gimbal. Worst case is it wears out a little quicker than normal. If it bothers you, I would plan on replacing it in the off season. Keep it full of grease and go have fun. I'm a pretty worrysome person, but that wouldn't register too high on my radar. JMHO

Re: Gimble bearing grease mistake!

Txboatboy,<br /><br />When you take the bolts off the OD and trim rams too, if that OD doesn't come off that bell easy-- do not force it! Be patient and slowly pry it off being careful not to booger the mating edges. You'll have to get an engine alignment tool {$60} to get it back on. Read the manual on this. Do not force it back in when your done. Good Luck<br /><br />PS Lube the Ujoint while you're in there.
