Dynamo belt alternatives

I forgot to order a dynamo belt when I ordered some parts from Worchester and don’t want to pay the postage to the US for one belt, has anybody got a cross reference for a modern belt alternative ?


I use Gates 3460 on my Mark V 3 1/2. The Spare Parts Catalogue calls for C.531 Belt, Fan Driving for 3 1/2 and 2 1/2 litre engines for Mark V and for 1946-1948 3 1/2 and 2 1/2 litre engines.

On my 3-1/2 L Mark V the belt is marked 5L460 but no maker’s name.
5L460 is a generic industrial size meaning a little over 5/8" wide (actually .656" or even 11/16") and 46" long outer circumference.

On my 2-1/2 L SS the belt is marked Gates TR28429 Green Stripe II Belt 20A1090 with US patents 5610217 & 6616558.

BTW the Gates 3460 cross references to 5L460.
