95 SeaDoo SPX Carb Removal Help

[sea_dude]

I need to remove my carb for replacement or rebuild but I cant remove the bolts. I'm sure they are rusted tight and have tried everything but drilling them out. I am very open for suggestions. Also, If I drill them out, do I just need to get the head off or are there treads all the way down the shaft. Thanks for the help.

With that setup Im not sure how you would drill them out as threads are all the way down. The best thing is maybe try a breaker bar or to break the "seal" try using box wrench with a hammer. Have you applied wd40? Where in Texas are you?

The threads are not all the way down the shanks of the bolts, just the last 1,5 inchs or so.
Those can be real he** to remove when corrosion sets inbetween the bolts and the carb bodies. Good luck. Often the body of the carb will split open, ruining the carb, if, and I say, if, you can get them to turn at all.

I have gotten them backed out enough to get a sawzall blade between the carb and the manifold and cut them off, but you usually end up with junk anyway.

Best to start looking for a used setup.

It will be a pain in the a** if you let the valve fall but you could remove the entire rotary valve cover and try removing them that way as you will have more room to work with.

Frankey01,
I am in Arlington but used the sea doo in Florida. It has sat for about 4 years here. I have tried just about everything else to get those bolts off. It even bent my hex wrench. No movement whatsoever. I'm guessing I will need another carb anyways rather than rebuild this one. I'm thinking that if I drill off the heads then I can lift off the carb and then cut the bolts down and drill out the rest of it at the bottom. Wont work of course if there are theads in the carb body.

Give me a call at 817 320 9750 I am in Ft Worth grew up in Arlington and could come by and give you a hand sometime. Do you have it out of the hull or is it in the hull still?

IF and WHEN you decide to cut up parts...Please check the parts prices and cut up the lower priced parts. I beleive the carb set is about $625.00, and the manifold is about $150.00. Make sure you sacrifice the part that costs you the least to replace

John,
I should have clarified that you cut the bolts, not the carb or manifold. *IF* you can get them to back out a little ( sometimes you can only get them to back out 4-5 turns, working the bolts back and forth a little at a time), then use a saw blade between the carb and the manifold to cut the two bolts. Once cut, position the carb body on an anvil or steel plate, but be careful not to damage it as you use a punch to drive the rest of the bolt out of the carb body.

Sea Dude,
Cutting the bolt heads off usually won't work, because the corrosion is between the body of the carb ( the hole through it for the bolt) and the bolt shank itself.

If you cannot get the bolts to budge at all, the next best method is to drill the bolt heads off, then use the punch to drive the bolts through the carb body toward the manifold. This is an extremely difficult task, with probably less than a 50% chance of salvaging the carb bodies if the corrosion is as bad as alot I have seen.

I have also come across a few exhaust manifolds that were similiar, with corroded bolts. It takes similiar methods to get them off of the clyinders sometimes.

Re: 95 SeaDoo SPX Carb Removal Help

Bill,
Here's where we differ, I would advocate cutting the manifold if I have to (IF I can't get to the bolts), it is the lower price of the major components and/or time expended @ shop labor rates-vs-parts prices(in our cases).... Also, the damage is usually limited to the area around the bolt holes in the manifold. This can usually be fixed easily in the shop. (to cut the bolts I prefer an air powered body panel saw, with a high quality hacksaw blade cut to the appropriate length for the job..the air saw has a faster stroke rate, and the hacksaw blades are a lot thinner and fairly flexible <<gets between the carb and manifold better>>)

Driving the bolts towards the manifold usually does vey little, the hammer and punch have very little effect against the manifold and the engine it is bolted to.

Then as you describe, in the first paragraph, knocking the remainder of bolt out of the carb bodies.

I see a lot more damage from people not knowing what to do to remove corroded fasteners than I do from the corrosion itself, I am sure it is the same in California, you see many items destroyed because of this...

In very rare instances, the bolt may actually be corroded into the manifold, but this is highly unusual!

John,
I always remove the rotary valve cover with the carb when I try to do this proceedure. When I drive the bolt through from the top, the force is not towards the engine or anything else but the air around it.

Re: 95 SeaDoo SPX Carb Removal Help

Me too, Bill, BUT nowhere on the posts did any of us make mention of that before now!!

Re: 95 SeaDoo SPX Carb Removal Help

I guess I just assumed that anyone with a couple of stuck bolts would have removed the whole sheebang from the ski.. But, you know what assumed means ! :)

Re: 95 SeaDoo SPX Carb Removal Help

Thanks for the great discussion and help on this issue. Right now the whole thing is still in the hull. I guess the first step is to remove the rotary valve cover with the carb. Seems like a good idea to me but a whole bunch of work for a novice like myself. I may just cut my losses and sell the trailer and give the SEA DOO away for free with it. Any takers? :)
