Hello tbuelna,
I've seen your input on that other thread of the OP, so you took an interest to this very intriguing but alas disappointing train of tech. issues.. It would have been so simple for the OP to give at least some of the feedback he/she was ASKED for, but no, or almost. Perhaps not yet..
Btw. it was on 25th that he/she was last seen on the forum, so hopefully there's not a more serious breakdown.
Three tapered b.s, I never encountered something the like of it, tapered b.s in pairs, that's the usual way. Question well put.
But then have a look at this one post of the other thread about the broken shear pin (with the pictures of the equipment in question): Imo it is to be concluded that the machinery & equipment is rather old / "experimental" ;-) / of faraway origin or else.
Regards
R.
But I'm not sure anymore whether it's the right thing to help to cure symptoms!
Because part of the picture of that other post / thread speaks to me that some of the common rules applicable in the industry might not be followed here, and thus by curing some symptoms a big event might be the next thing to come!
Feedback is most welcome, thank you in advance!
