Triumph trophy 900 starter problem help!
|
The starter is turning but wont engage, can anyone help with an answer?
Would it be possible to do it myself ith the parts and a manual (with
some laymans knowledge from 30 years biking)

Starter clutch is FUBAR'd. Well-known Triumph problem, especially on the
early 900s.
|
The parts diagrams identify the starter clutch as a "Spragg clutch",
which makes me wonder if there are really several ratcheting sprags in
the clutch, instead of cylindrical roller on ramps, like the typical
Japanese Frankenstein clutch.

Spragg clutch, which is like a non-tapered roller bearing. But the
|
Aaarrgh. It's got to me at last.
Sprag clutch. *Sprag*.
|
Take it up with Hinkley. "Spragg Clutch" is the terminology used on the
official Trophy parts diagram.
|
Silly sods. Sprag is the right spelling.
And we *know* they wear out......
|
And you don't bother to warn potential purchasers that a critical part
that will wear out and leave the buyer up the proverbial creek without
a paddle is buried in the engine?

"rollers" are eccentrically shaped, they cannot roll, they can only
wedge against the inner and outer races.
And that leads me to wonder whether a Spragg clutch is ever quite 100%
disengaged, or do the eccentric bits always rub on both races just a
tiny bit, wearing themselves out...

The bad news is that it's an engine-out job to fix, and a dealer will
charge you £800 for the job. If you're handy with spanners, then yes,
it's do-able, but an utter arse-ache of a job. I think you need one or
two odd-sized spanners for the engine mounting bolts.
Sorry to be the bearer of bad tidings.
