Drive shaft help

[Seadooguy10]

Hey all,

So I am in the middle of replacing the drive shaft on a 02 GTX 4TEC. I bought a new drive shaft, bellow, carbon seal, and bearing bellow. I am just wondering how tight it is all suppose to fit on the drive shaft. The carbon seal and its aluminum sleeve aren't tight to the shaft, the C-clip also isn't super tightly secured. The bearing bellow also is not tight to the drive shaft. Is this how it is suppose to be? Any help would be great.

Thanks

C-clip should be tight as it SNAPS around the shaft. The collar will be Snug and it slides over the C-clip. The carbon Seal will be VERY loose as it basically floats. The collar is what seals against the seal. While it spins a small amount of water will leak by and cool the seal.

Thanks for the reply, so it is normal for the PTO bearing to not be snug against the shaft? I attached two pics...thanks

The inner part of the PTO bearing is missing. The inner part has two internal O rings that seal against the driveshaft.

Yep, you are missing the bearing and 2 o rings

Seadooguy, whatever you do, go to www.sea-doonet.com, and click on the "tech specs" link on the left column menu. There you will find the service manual for the '02 GTX; look in the "drive" section. I have two of those ski, and just did this job because I though I had a leak at the carbon seal (The O.P.A.S. valve was leaking). The manual can guide you better than any single post. You can do a lot of damage if you don't get the drive shaft installed properly!


OBTW, did you replace all the O-rings on the drive shaft and the drive shaft bumper? The bumper is a time change item ... every 100 hrs. The floating ring is stainless steel.

With all new O-rings, it's a very fit, and I must admit I did struggle getting it all back together even with all the recommended Sea-Doo tools.

Coastiejoe, not do be disagreeable, but from close examination the drive shaft passes through the carbon seal; the carbon seal snaps tightly into the bellows and the clamp holds the carbon seal within the bellows. Since the bellows is on the outside of the carbon seal, it never makes contact with the drive shaft. Where the sealing comes into play is where the floating ring contacts the drive shaft and the carbon seal. The o-ring on the drive shaft where it meets with the floating ring seals the floating ring to the drive shaft, and the carbon "seal" allows a seal between the stationary carbon seal and the rotating floating ring. Correct me if I'm wrong, but the bellows never makes contact with the drive shaft.
