It's not "if" you will have to service that variable speed drive on that Logan,....it's gonna' be when, particularly if it's been sitting for years..
Tread lightly, and be sure to double up your pullers and "restraint" devices before unwinding the counter opposed springs.
Edited to add, there ain't a thing in the world wrong with that old mill, either, a actually envy the thing.
