Hello,
Ok, 96 GSX, low hours, was running great until it started bogging and needed carbs rebuilt and a wear ring, impeller too.
1.) rebuilt carbs (had trouble with a ceased bolt but got it off finally)
2.) removed pump and did impeller and wear ring - no issues

All was good going back together until I tried to start it up and it just clicked like a bad starter or dead battery. It did not crank at all. I determined the battery and starter were good so I dissassembled the whole thing again. I can turn the drive shaft with the plugs out back and forth but no full turns. It changes how much I can rotate back and forth each time. I can hear something in one of the cylinders under the piston rolling around I believe (pretty sure).

What can I do?

Any help would be appreciated :ack:

I just rebuilt my carbs on my spx and had it all back together, played on the lake for 5 hrs then while heading to the dock at WOT my motor shuts down. All I got was a click, pulled the air filter off and noticed a bolt back was out of the mouting bracket. It fell into the carbs then into the engine, resulting in a shitty day. Bye bye sbt bored 1.00mm motor. :rant:

Hopefully your problem isn't as bad as mine.

Thats sucks man! That is what I am trying to avoid. Luckily the motor never started or has made a partial rotation.

I just need to know where to start ripping this apart at to get to it.
 
take off the carbs and rotary valve plate. it might even be hitting the rotary valve itself. if not, you can see with a flashlight and dental mirror into the crankcase from there. like previous poster said; look for missing flame arrestor bolts. you can try fishing with a magnet, but if it is stainless, and it probably is, magnet won't get it. best bet-take the motor out and take the cyls off and be sure. i blew 3 rotary valve gears with the same 580. little tiny chip hanging up rot valve.

Hmmmmmmm...... The dental mirror is a good idea. I'll have to look around for one. I am in the process of taking the rotory valve plate off and I'll try to find something in there. If not i'll pull the motor.

Thanks man
 
I found it... well almost. Pulled the rotory plate off and couldnt find anything so I said what the heck and pulled off the heads and I saw a washer in the bottom below the crank. I'm thinking there is a bolt somewhere in there too.

Gonna need to pull the engine today and see if I can split the case and inspect. Is this a really hard thing to do? More like is putting it back together hard? I can do piston and rings with no worries. Never took the bottom end apart.......

any moderators feel free to chime in too... lol. please.
 
It isn't a big deal, but you'll need all the the torque specs and a torque wrench to do it right. This might be a good time to join as a "Premium Member" for the manual.

Well I was able to remove a washer from inside the crank case with out removing the motor. Dont laugh but I flipped the ski upside down and put in on saw horses and turned the drive shaft and it fell out. lmao. Now the motor turns freely unlike before.

Question, though. When I pulled the heads there was sand in the cooling ports and some fell in the crank. I vaccumed all I could and then I dumped oil in the crank to flush it out and then we turned the ski upside down to drain it all out. Now it looks dry in there. Should I do this again to be sure or just hope for the best. Or just get the matches out and burn this thing?

Thanks
 
Well I wouldn't use oil as it will stick to the sand particles and stick in the crank bearings...I would use like wd-40 and spray the crap out of it so it will float any sand particles out of the crank. If you do turn your seadoo upside down be careful not to break the rubber engine mounts, from the weight of the engine upside down. They aren't cheap, and will cause more problems later if they are broke. To check them, I would give the engine a good yank to see of they are still in tack after the upside down shake.

It sounds like your on the right track.
Keep us posted on your progress.

OK- i'll WD40 it again and hopefully that should do it. I ordered a gasket set from seadoo warehouse. The only thing I am concerned with now is the rotorary plate. How do I get it timed correctly? Do I have to buy the gauge?

Thanks
 
I believe in the manual it explains how to time the rotary valve for you, and I remember seeing a Degree wheel, you could print off and use on the engine for timing it. I'll look around to see if I can find the printable degree wheel. The rotary valve timing should be set to 147* at tdc, on your model if memory serves me right.
