10. Dave Nourish to the rescue.


With regard to the flywheel and the" hairy" camlobe competing for the same bit of space at the same time. Who do i know thats been here before ? Dave Nourish the supplier of the cams, manufacturer of Weslake race engines and guru of triumph/weslake race engines. Daves advice "You need about 0.015 inch (fifteen thou) clearance to take acount of crank whip at high revs. Just turn it off the flywheel outer". So cases apart and rods off. Stroll over to my favourite colchester lathe. Bung it in the 3 jaw chuck. Stick a revolving center up its oilfeed bore. Bang a dial test indicator on flywheel. Yup running true. Touch 45 deg tool on put 0.020 (twenty thou) cut on for good measure and feed it in. Approx 40 seconds later clearance problems gone. Cam and flywheel will no longer be bound in an intemate relationship and just be close neighbours independantly going about their own business. How civil .

No point in asking an experts advice if you dont act on it.
