[QUOTE="CarlHungness, post: 174057, member: 2517"] I I used the B-TH from 2003-2023 with a short Allen bolt on the right hand side, the one that is a real challenge to get in with the long allen wrench/driver, so that's not an issue. I DID vigorously lap the ATD to the Lucas shaft and hope I didn't over do it. I just ordered a brand new ATD for 250 Pounds sterling plus extreme postage cost to the US. NOW I have the Lucas Workshop Instructions printed out thanks to a fellow member on this forum. Here's the quote that has set me on my ear: NOTE: When refitting or replacing an auto-advance unit [I]do not press [/I]the unit right home on the armature driving taper,[I] but allow the retaining bolt to do this as it is tightened.[/I] In this way the danger of locking the retaining bolt before the auto advance- unit is fully engaged on the taper, or of accidentally engaging the extractor left hand thread with the retaining bolt will be avoided. The italics are mine. I don't know how I learned it, or where I read it, but (lately) [I]I have been setting the unit with a socket. [/I]That won't happen again. Now my only fear is my lapping of the old ATD to the shaft may have decreased/changed the taper on the mag and all I can hope is the new unit goes on and matches the taper, etc. I'll have the unit by the end of next week.
