Twins / A10 Squealing like a pig!
« on: 20 November, 2017, 13:41:04 »
1959 A10, Was a Gold Flash. now has ally head and Spitfire cams.
Starts fine, runs fine but on it's last but one outing, developed a nasty squeal. It goes like this;
Start up, run static for about 30secs-1min, squeal starts from engine area.
Sometimes it starts shortly after setting off.
Clutch has no effect on the squeal.
No excessive smoke from exhaust.
I've only been out on it once since the noise started. Just to test it. Noise started shortly after I set off.
Thought it may be slipping dynamo belt so tightened it....still the same. slackened dynamo belt off completely.....still the same.
Checked oil, it's returning fine. It's fresh oil.
Primary side is "Bob Newby" clutch and belt.
Engine has done about 1500 miles since professional rebuild. Same for gear box.
Suggestions please. Thanks, Rick.
