Hey Guys,
A word for the wise,the 29K51,53,56 all have real small & brittle gears in them that have been obsolete over 30 yrs.I get alot of calls for people wanting gears for them & have to tell them they have a parts machine.All the upper head parts are the same as the 29K58,71,71 which have larger gears in them that you can still buy & use this for parts.
Hope this helps,
Bob
