Hello, I need (think) to put a new worm wheel in my Lionel 736 Berkshire locomotive (magnatraction). The engine goes in reverse well but when going forward there is alot of slipping or grinding. The gear on the engine armature is good. Is the procedure hard to do? I'd hate to ruin the locomotive by trying this but the part seems rather in expensive so maybe I can buy one and tackle this myself. I also have put a couple of shimms under the motor but it just does'nt stop it enough unless I just want to go in reverse all the time.
Thanks guys for any advice,
Jeff
