Message Board - Machinery: Sump plug issue

Hi.
I wonder if anyone out there can offer some advice or tip.

I have just changed the transmisson oil on my JD x495 but when the sump plug came out it looks like all the thread from the sump has come out with the plug. As a result the plug now screws in without getting tight, and leaks.

I guess the obvious answer would be to buy a larger plug and cut a new thread. However, I wondred if there is a product, paste or glue or something, that I could seal the old plug in with but still pull out next oil change.

Any advice appreciated.
Thanks

Probably best to Re-thread, but maybe PTF tape (plumbing) may be worth a go.

If it were me I would not be taking a chance on effecting a repair which, if not properly done, could dump a sump-load of lubricant on some playing surface or other. Of course, the potential is also there for severe engine damage too.

I would be looking to drop the sump and have the offending plug hole re-threaded by enlarging, retapping and fitting a slightly larger plug carried out by a light engineering company or similar.

An alternative may be to utilise a Heli-coil insert (Google it) which can be purchased in do-it-yourself kit form but does need a degree of engineering expertise to install.

I agree with Mario totally on this. The consequences of a whole sump of oil dropping on the turf aren't worth thinking about, and would easily be noticed prior to the engine going bang. I was actually wondering whether there was a helicoil or even a threaded sleeve in there already, which you have removed with the sump plug accidentally or because it came undone more easily than the plug itself. A lot of sump drains are brazed into a hole in the steel and the softer metal they are made of 'threads' more easily with the steel magnetic plug. Even more so on radiators.

Try a heli coil first, other than that, as Mario says, sump of and re engineer. Never worth taking the chance.

Plus a new sump gasket to avoid drips on the machine shed floor :-).

Thanks guys. Validpoint about oil leaking.
I did wonder if a longer plug would work as I can see the sump housing is threaded for at least twice the depth of the sump plug, but finding a longer plug has proved too difficult. Tractors off tomorrow to be recut.

Cheers

Sounds like someone might have stuck any old thing in rather than the original sump plug which they lost in the grass or threaded carelessly when tightening.
