Triumph Repair: Triumph cam chain oil slinger, chain oil, cam chain

Question
I am re-assembling a Triumph 1147 engine and forgot which way the cam cam chain oil slinger should face when re-installing it on the crankshaft.  Can you tell be which way it should go or does it not make a difference?

Answer
Hi Jim,
The slinger tries to keep some of the oil away from the front seal and most engines have the cup of the slinger face the oil seal (forward) I have opened up many engines that had it turned around and did not seem to cause a problem. The early Spitfire has the cup face forward as most do.
