My old Cub Cadet Tractor, which I bought in 1985 used, has a stripped
oil drain plug. After many oil changes, the hole just wore out. Is there any
type of fix, like a oversize ,self threading bolt out there? Any help would
Take the drain plug to an auto parts store and ask for the proper size
heli-coil. Get advice on how to install it. A heli-coil is a spring-like
coil intended for such stripped out holes. I'm not sure if heli-coil is a
brand name but any machine shop or auto parts place will know what you're
If this is a stamped steel pan, the threaded part will be too short to
effectively accept a HeliCoil. Rubber expanding plugs are a disaster waiting to
happen as the hot oil often hardens the rubber and the vibration does the rest.
Simply buy a new oil pan and install it. This can't be a big ticket item, and
the replacement can be done by anyone capable of changing a spark plug. The
damage was casused by some idiot overtightening or cross threading the drain
plug to begin with.
Dealerships have flat rate books to quote you labor cost for the fix, so that
could help you judge whether you want to tackle it. Good luck.
go learn something on small engine a heli coil will work. The oil drain hole
is not as thin as it is on cars drain pan.
I would try and re tap it to the next size up with a new drain plug. any
hardware store with pipe stock should have a the next size plug in stock and
the pipe tap to do it with.
There are self threading oversize drain plugs available for automobiles.
Take your old plug to the auto parts store for the closest match. Do not
give up without checking all available stores since they are not real fast
moving and not all stores will have them.
I would go with a helicoil if you have enough metal there to get it to work
then install one of the valve type drain plug replacement to avoid wear and
tear on the replacement you could even try some JB weld to just glue a
replacement drain plug in place!
There are also oversize plugs made for such situations!
