SUMP PLUG

[SPADGER27]

Has anybody a bright idea how to remove a rounded off brass sump plug which was last attacked by Bodgit and scarper. The plug is completely rounded off and hammer and chisel has been tried

Gator Grip?

File some new flats on, even if it's just a pair so that you can get an open-ended on it.

Stilsons will get that out

[slewthy]

Yup, had one of those on the Volvo - local garage couldnt shift it but a Stilsons (plumbers wrench) got it. Forget a normal wrench - you have to grip and turn. With a Stilsons, you just have to turn - the harder its stuck, the tighter they grip. Even in a tight space.

What size is the bolt? these may fit http://www.irwin.com/tools/screw-bolt-extractors/5-pc-bolt-grip-expansion-set

Yup, stilson should work, or I have some very sexy spanners from the US that would nail it. New one's quite expensive...

[SPADGER27]

Tried stilsons . tried different sized spanners tried hitting my head on a wall...very little to grip on

It's often a case of finding stilsons or pliers that fit just right. I had a similar problem with the filler plug for my gearbox. Stilsons proved to big and slipped, the Knipex Cobra did get a grip but I couldn't exert enough force. a mate suggested using a hoseclamp to keep the Cobra closed, and that worked! Been using the cobra for smaller rounded off bolts everytime since.

With everything you have tried have you also used heat/cooling in conjunction?

A blast with a blowtorch followed by a squirt with penetrating oil might help

If the irwin sockets are big enough they will move it, they are great for rounded off stuff

I am sure I read somewhere they are a standard size plumbing fitting available for pennys from a plumbers merchant.

OK it's messy, get the oil drainer ready, drill a hole right through, allow the oil to drain, then use an easy out.

 

Then chuck some paraffin oil down it to flush any possible swarf.

I like Scott's idea...drill a hole through the remains of the head. I'd use a short length of steel rod through the hole resulting, and get a socket that's a tight fit on the remains of the head...then cut slots in the socket to engage the steel rod through the hole. Heat the thing up before you exert any force on it... a good squirt of WD40 down the square hole in the socket, then in with the T-bar with an extension added to the bar for more leverage, and HEAVE!!!! That ought to transmit enough torque to get it out. I also agree with Malcolm, I think the plugs are a standard plumbing fitting.

 

What fun it is, all these little problems to solve.....

Correct, but I went for an upgrade and sourced a magnetic sump plug for around £8

[pete]

could you weld a good nut on to the old one

[andydclements]

It's brass so at best it would be soldering.

[Vanya]

If it's brass a dremel should go through it like a knife through butter - as someone else suggested, try cutting it down enough to get an open ended spanner on it. Should come off that way?

Paul,

Did you get it off? I have a similar issue
