  • Oil Fill Tube
  • My 9n oil fill tube fell out while mowing today. What's supposed to hold it in (besides gravity)?

  • You could take an exhaust pipe expander tool and stretch the pipe just a little to tighten it up a bit.
    Or you could bend it out of round just a little, or take a nail set and put a dimple in two sides from the inside out about an inch up from the bottom...

  • Loctite also makes stuff that is supposed to lock in races that are not tight enough anymore.

    Never tried it on your application though.

  • The original interference fit can be darn difficult to remove, but after the tube has been removed and replaced, or run into, the press fit may be gone. The right tool to use to restore the press fit is a tailpipe expander or something similar. Most muffler shops have them. The trick is to expand the tube just enough to restore the interference fit. It's easy to go too far, and then not be able to install the tube without destroying it.

    Another probably safer way to fix the interference fit is to find a piece of heavy pipe that barely fits into the lower part of the tube. Clamp the pipe in a vise with one end sticking out about 1", slip the tube over the pipe, then use a hammer and punch to make a few small dents around the diameter of the tube. Each punch mark will create a raised area around the edge of the punch mark. I use a nail set rather than a flat faced punch. The nail set creates a small bullseye raised area.

    Epoxy as Tim suggested also seems to work for many folks. JB Weld is often the fix-all for just about everything. You probably don't want any JB Weld going into the oil pan. Apply any glue to the tube so any that gets scraped off is on the outside of the engine.

  • I applied a dab of Epoxy on mine back in 2003 and it is still holding. They do get worn and Carpenter and Just8Ns sells new ones exactly the same as original. I bought case of 6 NOS ones years ago still packed in the Cosoline paper.
