How do we know the quality of an OEM is any better than that of a remake available today. I passed my failed series 3 layshaft onto a mate who xrays metal . He came back with results saying it had tiny fractures all over.
Having only owned that 2nd hand layshaft for a couple of year prior to its failure , I had no idea of its history.
The fact of a newer layshaft is it hasn’t been under stress that we know off. I personally run a mb at the moment but that’s because at the time 2015 I thought it was a better option. No proof i know.
There are now a few options out there and I for one would be putting a newer layshaft in rather than an old one in something I was planning on using.
One more point to raise is , how many new (of any make ) layshafts have failed ? I personally haven’t heard of any.
You are absolutely right to follow your own reasoning & take comfort in that decision
But my reasoning is also sound. I would be prepared to use either OEM or a brand new replica in a motor were they subjected to the same non-destructive testing & analysis. With the OEM, that will have conformed to precise manufacturing principles @ some time, many years ago, & with an unknown history since, should ideally be checked for continued use. Unfortunately, with the best will in the World, I cannot say the same for the brand new pattern layshaft, despite anything you, or anybody else, can say.
Honestly, I take my hat off to anybody that cares enough to argue the point over something which is important to all of us, rather than be apathetic, which is so common these days! After all, I don't know anybody that voted for Boris, so presumably most voters stayed @ home.
As an aside, I have scraped the surface of the feasibility of low volume, non-destructive testing of components. The U.K. doesn't seem to be brimming with contractors offering the service, except for the rail industry, which would appear to indicate that they are certainly not embracing a culture of new is better. Mind you, knowing how money comes first in this country, the Rail Franschises must have had their arms twisted halfway up their backs to comply
