If the old style torque limiter fails, you get the "clack clack" symptoms, the starter still doesn't turn the engine but it's a different part that needs to be replaced.
So what does the limiter actually do..........does it act as a shock absorber when starting? I shall have to get my spare cover out for a good look and refresher course!
