Hit Wave then Seized up bearing?

[rgb4]

I have had my seadoo out multiple times this year and it has been running great. As I was cutting I hit a wave, kinda sounded like my propeller came out of the water (maybe, not sure) and then when I came back down I heard a pretty solid "thud" and my seadoo quit running ASAP. It sounded like something seized up. I tried to start it again (i have the two beeps), I can hear the starter try to engage but nothing. Its not even moving.

I opened up the rear hatch and I touched the propeller driveshaft bearing and that sucker was hot. Almost hot enough I couldnt keep my finger on it. Is it supposed to be that hot? Could that bearing went out and locked up?

Any thoughts would be great.

Thanks.

It sounds like your pump seized. Remove the pump cone and see what the lubricant looks like. You also could go ahead and remove the pump and see if your motor will turn over, if it does that's good news, but you will need to rebuild the pump.

When was the last time you greased the carrier bearing assembly?

With the pump seizing it can keep the motor from turning over I'm assuming? That make sense to me.

I plan to take the cone/impeller off and see if the motor turns over/moves.

Can the carrier bearing assembly (is that the one on the shaft underneath the seat/in the little compartment you can lift up?) cause this as well?

I've got the overall idea of how to remove the impeller/cone. It seems as though there are a couple bearings that could cause the shorter impeller shaft to seize up?

Recommendations for a good rebuild kit that includes the bearings/seals/anything I would need?

Thanks

I forgot about the carrier bearing in the 97XP (it's the only ski that has this), and re-reading your description, I would also say it's the carrier bearing. Parts are a little has to come by, so if it is the carrier bearing try Nick [MENTION=41828]Minnetonka4me[/MENTION] or OSD parts.

Osdparts.com has all you need new and cheap. It's almost not even worth rebuilding vs buying new from them. But to answer you question, if that seizes it could stop the shaft.

So to remove that carrier bearing I need to take the pump off and do I need some sort of alignment tool? Anything special tools I need to replace this bearing (do I need to press this bearing on)? Do I need to remove the shaft to replace this bearing? Thank you for all your help.

 

[racerxxx]

When I did the one on my HX, which I think it's identical to your ski, I used my alignment tool. It was way off. There is a ton of adjustment in that joint. If I can get internet access tonight I'll try and post what you need. But first, you need to diagnose off this truly is what's wrong.

I replaced the carrier bearing in my 02 XP. it's adjustable in lots of ways. Basically I reassembled the whole thing including the pump, then tightened it down after bumping the starter. Been running fine for a season now. Not saying it's the right way. Just with the pump on it should line up...

I got the parts from OSD. actually it was my 00XP, but same setup. 97 may be different since it's a 787

It's a spherical thing pressed between two metal rings, that when you bolt Down holds it tight. I grease it once a season in the fall when I do all maintenance.

 

[rgb4]

To verify that its the carrier bearing I need to take the impeller/pump off and try and rotate the pto/driveshaft? (take the sparkplugs out?) and if the driveshaft doesn't spin its the carrier bearing?

Any other tips to identify which bearing could be at fault?

Thanks I'm at work right now and will be getting home around 1am and will want to figure this out asap. I hate having stuff broke and not knowing whats wrong.

 

[SabrToothSqrl]

Remove pump. youll be able to spin the impeller by hand if it spins. If you can't, it's seized.

Remove spark plugs and yes, you should be able to hand crank it. If that doesn't spin. It's either the carrier bearing. Or engine.

 

[rgb4]

ok before work today i removed the impeller and spun that by hand and took the cone off. it spun easily and the oil in the cone looked good.

i popped the c clip off the driveshaft and tried pulling the driveshaft out. but i heard that theres lots of problems getting the driveshaft out. is there anything else that needs to come off that driveshaft to remove it? Does the bearing come with the driveshaft?

Kinda at a loss right now where or what I need to do to check the carrier bearing. the last thing i need to check before investigating the motor.

thanks

Any tips of tricks to get the driveshaft out? I read that someone wrapped a chain around the driveshaft, used a bolt to connect it together and then had the chain attached to a tree and pushed the seadoo away from the tree. Any other unique ideas to get the driveshaft to slide out?

I'm really hoping that its just the carrier bearing. So if I get the drive shaft to come out should the carrier bearing slide off easily and if its hard to get off that means the bearing has seized up?

thanks.

Packing up to head home, if no one answered by later tonight I'll let you know. Sorry about that.

Racerxxx that would be great. Been trying to think of how to attached something to the driveshaft so I can pull it out. Only thing I can think of is to use a pickle fork in the c clip Groove and try lightly tapping it out.

 

[SabrToothSqrl]

Is this the carbon ring? Or grease bearing?

If it's a carbon ring, you want to slide the rubber boot back to expose the c clip, before removing said jet pump. Else you'll have a heck of a time doing this.

 

[rgb4]

I already removed the c clip. I'm trying to get the carrier bearing with the grease zert off. The carbon ring would not cause the driveshaft to not turn. Right?

So. I want the last bearing off

 

[racerxxx]

OK, C-Clip is off, can you slide the stainless top hat the covered the c clip? If so than that is good. I would Try not to mess the shaft up by prying on it. But sometimes you have to do what you have to to get it apart. It's possibly extra work, but you could remove the 4 screws that mount the entire carrier assembly to then pull it back just a little to see if you can disengage the mid shaft from the drive shaft and see if that X member will spin freely. It's tight in there, but I can get both my arms in my HX back in there and that is smaller yet.

Take the 4 screws out of the X piece #29 You're trying to disengage the drive shaft from piece #24. I just don't know if there physically is enough room to pull it back.

Here are the parts. Also if you need a driveshaft because the bearings ate it up you will need to source a used one. Tonka may have one and I know there are several on Ebay, one for $45 shipped in clean shape.

racerxxx i appreciate the thorough response a lot. So just to verify I take out the 4 bolts holding #29 and I can slide that back even if the bearing is seized but I will NOT be able to rotate it if its seized?

Thanks again!

 

[racerxxx]

Yes, remove those. I assume you have the pump off as well. If it truly is seized, the shaft and the #29 with the carrier assembly should go with it. It's unfortunate that since the drive shaft just won't pull out easily you need to find another way to verify that this bearing is good/bad. Having an HX which is the same exact set up like your ski I can't think of another way to get at it. I could be sending you down the wrong path but does the pump spin freely? If the pump isn't off yet do not go down this road until you can verify you pump is good.

 

[rgb4]

Yes. I removed the pump/impeller. The "prop" spins freely on those bearings. I'm headed home from work now so I'm going to take those for bolts off and see if that carrier bearing is seized to the shaft. I sure hope so.

 

[racerxxx]

Remove the spark plugs and the PTO cover and try and spin the engine over by hand. I just don't want to see you do extra work. For me, I wouldn't care it's just another avenue to explore. I just hate wasting guys time, LOL. But we are probably heading the the right direction since the driveshaft should slip right out.

 

[rgb4]

so i just removed the 4 bolts for #29 and slid the driveshaft out of #24 i believe. Hit the start button and she turns over!!!!!!!! So happy its not the engine and its just that stupid carrier bearing.

So how do i get that carrier bearing off the driveshaft since its seized on there?

I was hoping to re-use the drive shaft but doesn't really matter I guess.

Thanks for all your help!!!

 

[rgb4]

trying to find a drive shaft closer to me.. if i could save the driveshaft that would be awesome.
