Daniel,
The clutches over here in the colonies were on Spitfired Midgets.
The problem was that the clutch, with fan, would detach from the end of the
water pump and go sailing into the radiator. The attachment was
accomplished with a corrugated spacer that was crushed as you pressed the
clutch onto the pump shaft pulley extension. (part no. UKC759) Not a
terribly reliable connection, and prone to rapid failure if either the pump
or clutch themselves were deteriorating.
Go to a breakers, and look at the number of radiators exhibiting a
circular wear pattern. Spitfires had the same problem. Also, TR7 (wedgies)
used the same clutch and crush ring, but on the idler pulley. Never seemed
to fail as much. (but when a TR7 pump goes bad.... hoooboy)
