Hello

Thanks for the posts.

I found a thread on here:

Hobbymat thread

Which mentions:

"The Tufnol gears have a metal centre bush, and the other problem that can occur, as on mine, is these gears being pushed slightly off their bushes. This is caused if someone is impatient and heavy handed when using the levers to change gear, without carefully rotating the spindle back and forth to allow things to line up and click into place."

I removed the left side cover - all seemed well, (lots of grease on the gears), and the drive dogs seemed intact on the Tufnol gears. Manually lifting the gear change forks engaged the gear change correctly, just the levers don't provide enough 'lift' for engagment.

Bearing in mind the thread mentioned above, I carefully put a flat blade between the upper gears and quite easily nudged the gears down on their bushes, maybe around 2mm.

With that done, full fuctionality has been restored. I suspect that the previous owner(s) had been changing gear with the motor running. Hopefully this won't happen again with carefull treatment.

Thanks again for the posts.

Sorry to ressurect an old thread.

I've just bought a second hand 'Prazi_BF400' which is the same machine as the BFE65.

I have the same issue, the drive runs OK with the gear shifters in the lower position, but the gears won't engage at all if the speed change levers are rotated to the upper position.

The gears appear to be all lined up correctly with their meshing counterparts.

I'm stumped now...
