Hello Folks, this is my first post...it's great to be here!

I'm a long time model railroad enthusiast but I was just recently grandfathered into Lionel O-gauge through inheritance of my brother-in-law's gear.
It's been a couple of weeks now, and I think I'm hooked!

Anyway, I have a postwar 202 diesel locomotive. Runs great one direction, barely moves in the other. I confirmed it has the famed motor bearing plate shift. I read the Lionel service bulletin which advises to stake the case on either side to remove the slack. Before I proceed are there any other alternative/better fixes?

I don't mind staking the case but I thought I'd check first.

Thanks in advance!

Cheers, Ken
