I just heard that there is a recall on some Rocket III's for a defective seal on the final drive unit. The affected bikes will have the entire unit replaced.

As I mentioned on another thread the problem appears to be with the supplier as they apparently contacted Triumph about it, how on earth can any amount of R&D sort out a problem with a seal from an outside supplier ?
According to the Triumph Customer Services/Warranty Department they've yet to have a failure which doesn't appear to ring true with a report of a rear hub failure on the American Triumph.rat site ........
The seal has to leak to loose the 0.17 litres of oil for the rear wheel to seize 0.17 litres ain't alot but I wouldn't expect the seal to fail and all the oil to come out instantaniously as it's not under pressure like the engine oil is so it should be visable long before it all leaks out. I would have thought the oil leaking onto the rear tyre would be noticed long before the hub ran dry
A few guys in England seem to be getting new shocks when the final drive is replaced. Is this because Triumph could be admitting that the originals were oversprung and underdamped?
I checked the Aston this morning everything appears to be fine. I will check the Diablo tomorrow at work when I can have a proper look when I get it on a ramp
According to the Recall message on the Official Triumph web-site the oil leak is from the final drive unit into the drive shaft, which is also a closed cavity.
I have to assume the housing of the drive shaft (which normally does not contain any oil) will fill up and you will not notice any leaks externally. So there is no warning before the unit melts down!
Hence a recall (= immediate replacement of all vehicles, approach all owners actively) in stead of a service action (= replace at first workshop visit or if customer reports)
Mine was spotless but mechanic said seal was leaking inside, so Tom is right all the oil could bleed into the drive shaft housing causing a hub failure without warning.
Les.
Had it replaced yesterday (2/4/2005) Just took an hour at Bransons in Gloucester. It's still a positve thing when manufacturers admit their mistake and take corrective action.
I make a living dealing all day long with aftersales issues which are sometimes small problems that can, if not carefully handled, escalate out of all control and yes it is f!$%ing important to get it right first time .......
