While changing all the hoses on S1515 I decided to replace the fan belt as the one fitted was at the adjuster limit. A mail to Brother Scott produced the Ferodo V108 which cross referenced to Gates B38 with a 42.5" outside diameter only to find it just fitted between the water pump a crank pulley. With a tailor’s tape measure I measured around all the pulleys with the dynamo hard against the block and got a measurement of 43". I hadn’t noticed any markings on the old belt but a scrub with soapy water revealed B44 which is 46.5" outside diameter which is now on order.
So what is everybody else using?
