I'm trying to assemble a decent set of ECG rockers, (on new shafts) from two sets on hand. Am left scratching my head, because they all have the interference style adjusters, but most of them are so tight in the rocker, as to be almost impossible to turn. Even using a 9" centre to centre spanner & even a short flex bar, with penitrating oil, they are extremely tight. (On the other hand, I removed one adjuster from a very worn rocker & when I switched it to a better rocker, it was only finger tight all the way down.)  There's no rust on the tight threads & they are not crossed. I went to Eickman's Y-Blk book, pages # 36 & 37 but that just caused confusion, because one of the illistrations shows an ECG with a locknut style adjuster & the 1.43 rocker with an interference fit adjuster. Is that a mistake? It was my understanding that the ECG rockers of 1956/57 all used the interference fit adjusters. No?. The only other thing that comes to mind is, that someone has replaced the original adjusters with oversize thread adjusters, which were available at one time. If so they weren't needed! There does not appear to be any markings on the adjusters.. Any clarification would be appreciated.. Thanks
