B-W Velvet Drive clunking
John,
That's completely counter-intuitive. Can you elaborate? Thanks. ==== Charles T.

It's your low idle speed that's causing the noise, BW's make noise at low RPM's. Your idle should be up around 700 to 750 RPM's. Your hearing either back lash, or the clutch pack. Crank the idle back up where it belongs before you really damage the gears. |

Crank the idle back up where it belongs before you really damage the gears. I had an old boat that one engine was not running on all the cylinders, turned out to be a distributer cap problem. Well the BW transmission started making clunking noises, it went away if I increased the throttle. When I replaced the cap it disappeared for good. I spoke to a boat transmission shop guy that indicated that low RPM's can cause noise due to insuffeciant fluid flow to the clutch pack, causing engaugement problems, or, because of how engine RPM's tend to be very unstable at very low engine speed (put a timing light on it to see just how bad they can get) this causes noise due to the backlash in the transmission gears. |
