PINS?
Iain,

You don't say whether your team has removed the two pins that lock the transmission output shaft from being over-driven by the load. If they have not removed the pins, the system will produce exactly the symptoms you describe, with a really nasty harsh and loud clack/clash. It may also leave the motor locked up and stalled, if you continue to hold the stick in reverse after this symptom occurs.

If you have not removed the pins, I urge you in the strongest of terms to do so without putting further crash stress on your drill gearboxes. You are headed for guaranteed headache otherwise. There are several threads in this forum that can help you with the details of pin removal.

Good luck.
Dodd
