Walter V-drive failure.

Recommended Posts

TimbrSS

Had the u-joint between transmission and v-drive expire at 770 hours. 2006 247. 8.1l with 5000# ballast. Surfing with normal setup, and just exploded pulling rider out of water. You can see where the u-joint tried to exit the case as it was flopped around while in gear. No warning signs/sounds and had just checked fluid level before outing. It's a 1.21:1 ratio. I'm lucky that I have a 1:46:1 v-drive sitting in the garage.

Started pulling it out. Had a difficult time getting it off the transmission and had to quit to head to airport. Just need it to come back another 1/2" or so.

The drive side still spins freely, so early assumption is the joint just failed... The gear box may still be ok, so i would have the choice between gear ratio. Going to give 1.46:1 a try... That's why I had purchased the extra one anyways. 

Going to switch to Glide dripless shaft seal and install new strut bushings while I'm at it... Had those parts laying around too.

I'm impressed...Vdrive, bushings, AND new shaft seal "just lying around", nice!

Stanley wheelhouse is on notice....

Hmmm, a friend who bought an '06 247 had his v-drive go kablammo last summer.  Very odd, as I don't recall hearing any issues with them except oil leaking.

Wow is right.  They are always thought to be bulletproof.

was going to say 5,000# of ballast holy cripeys!  I must be lame, I don't surf behind a boat, wakeboard only and still only use factory ballast with no plugNplay system.

Didn't know 5000# was that much. (with a light crew). I was just thinking of getting about 500# more lead.

The v-drive did not want to separate from the trans, so i decided to take the v-drive off the u-joint housing.

The u-joint coupler was a bit warped and didn't want to release easily without a fight. A 3 jaw puller is the way to go here.

The splines are a bit mangled, so i pulled the output shaft to try to clean it up a bit.

I went ahead and replaced the strut bushings, abd the shaft seal.

Should be able to install new v-drive later today.

The only silver lining is you do not need an inspection mirror to do the dripless shaft seal.

Is that the Vesconite bushing?  Where did you source it?

Looks like Glide Seals bearings.  Installed those on mine last summer.

New V-drive is in and the wave machine is back in action. Need to switch to a less aggressive prop to match the gear ratio change. 15 x 12 will be replaced with a 15x14.25. Special thanks to Engine Nut for part numbers for tans seal and nut!

You the man,!

if I was presented with the same challenge,  I think I would just start crying thinking about what they were going to charge me !

So what let go, was it the u-joint or the v-drive?
