Gday Mark,

Yes I've often wondered too what's fact and fiction about torque
potential at each wheel of a syncro, depending on any scenario.

For example, a stock standard syncro with a rear wheel spinning,
wouldn't the torque be 100% thereabouts at the front wheels? Then by
extension, one back and also one front wheel spinning at the same time,
that means no torque anywhere.

Then in my case when the front solid shaft is coupled, wouldn't the
torque potential at each wheel change in say two different scenarios,
first with no wheel spinning and then the other, one rear wheel
spinning.

Or is it simply that torque isn't split, meaning 100% torque potential
is available everywhere that wheel sets are gripping?

Or is this also just more conjecture? Perhaps there is a known
authoritative source on all this?

Cheers.

Ken
