Help - Gear box oil filler plug rounded off

[marjon]

Well done.

Was it the torque bit hammered in trick that worked?

Now.... If you have a welder and just weld it in place it can be reused.

Replace it with an old fashoined 1/2" square (external) similar to the LT77. That way when it rounds off at least you have some protrusion to get some mole grips onto!

Well done.

Remember, it doesn't need torqueing up tight- it is a taper thread. A couple of wraps of PTFE tape will help to seal and help to get it undone again.

Yes - managed to persuade the torque bit in place, then gently applied the undo pressure - held our breath! OH has welded it in place

Ok - after the thrills of getting the plug out, and new gear box oil in, it appears that the oil is escaping from a hole at the bottom of the bell housing . That would answer the mystery of where the oil has gone.
2 questions: the oil is dripping out of a threaded hole at the middle bottom of the housing.
1. Should there be a sump plug or something in there?
2. It deffo seems to be the gear oil (nice and clean, looks exactly like the oil we've just put in) - presumably this points to a seal having gone between the clutch and the gearbox?

No there should not be a plug in there under normal conditions. The hole is for a wading plug when going through deep water. If it is leaking gear oil from there then it is indeed the input shaft seal on the gearbox that has failed.
It should be fairly obvious what oil it is as it is another gear oil from the gearbox input shaft seal. Or engine oil from the rear crank seal.

Unfortuanlty to replace either of the seals is a gearbox (or engine depending on preference) out job.

Thank you for the clarification re the wading plug.

Botheration re the seal - sods law given that we've just had the clutch done so if we'd checked earlier we could've had it done at the same time. Have to check down the back of the sofa for some loose change
