Hello,
I have this engine, 6-8558.
It ran great for years, was out of service for 5 years, following a move. Just put up a new layout and oiled & lubed all my engines, when I ran the 6-8558 it is very noisy.
It was noisy just on curves at first.
I removed truck from motor and checked gears they all looked OK, I lubed again.
After putting it back together now it is noisy on straight track too, what's wrong?
Al
