HELP!!! WR426 Sump plug is here to stay.
Posted July 17, 2006 - 01:18 AM
I'm having a hell of a time getting my sump plug out of my 426. I've searched and read the relevant forums that I could find with no luck, so I'm hoping someone out there has some brilliant (or any) ideas!
I was changing the oil as usual, 2 weeks after the last change. I removed the frame plug and drained the majority of the oil, then went for the sump plug.
First of all, the hex rounded very quickly when trying to get it out, which I thought was unusual since I am always wary of over tightening. After my usual ratchet and socket I try a shifter, spanner, smaller size spanner and tried to belt it in with a hammer, vice grips - all with no luck. Plug is now looking a little second hand.
So I went to the local and bought a replacement plug and washer, the right size screw extractor and started to drill it out - usually the last resort, and the process guaranteed to work
Trying to be careful of over drilling the plug, I put the extractor in and started turning anti clockwise as per usual. Then my extractor snaps clean off, with a big chunk stuck in the plug! &%$#@! do I do now? I pulled out the grinder and carefully squared the plug off to attack again with shifter, vices etc...
So off I go and buy a larger extractor and start the process again. Now I have destroyed this damn plug, and have no idea of how to get it out. Nothing I have tried has worked and I'm now worried that I've accidentally drilled into the sump thread itself when drilling at odd angles...
My bike is slowly dripping oil out of the plug. I've obviously drilled too deeply or in the wrong direction.
I need some opinions on how to proceed - any and all advice is appreciated!

Have you tried a screwdriver on the edge of the nut with a good smack of the hammer?
If this doesn't work, you could try welding something such as a bolt lengthwise onto it. Could be that the heat and the leverage combined will be sufficient to loosen it . Even if you have damaged the thread, as long aas the new bolt screws in tight, it should be fine.

I suggest you do the same!
How tight do you do up your bolts?

I don't actually do my bolts up that tight - generally firmly tight with a spanner - I've learned the hard way previously! The graphite sounds like a good idea regardless though.
Thanks Wayne - the screwdriver sounds like a good last ditch effort on my own - if no go, then I think welding a nut or bolt onto it may be my only choice (I've got a feeling this is what I'll be doing).
Any idea where I could go to get this done? Will car/bike mechanics generally be able to do this (I'm dubious), or will I have to hunt down an engineering or fabricating business.
Or should I pull off the skirt, go buy a cheapy and do it myself? Is it hard/expensive?

I am guessing the tight confines isn't helping much either! Good luck!

I went to my local mechanic who looked, laughed, then grabbed an air compressor chisel - bolt was off within 10 seconds.
The relief is indescribable - besides feeling like a complete dumbass, it was a better solution than I had hoped for! The screwdriver or chisel with a smack of the hammer was the correct solution for this after all - apparently there is some concern over warping the case with welding - maybe if the welder wasnt very good (?), but this is beyond my expertise...
It's a happy ending after all, and thanks again for the help
