Help! Sump plug stripped

**oldskool** · 27th May 2009, 15:26

My sump plug is stripped. I had hoped to do an oil change before riding this weekend. I tried to undo the plug but all it does is just keep turning without unwinding. What is best way to remove the bung (I tried vice grips and pulling motion at same time as unwinding action but it ain't happening), rethread the hole and get it sorted? What sort of engineering shop do I need to go to for those coil/thread thingies?

Any bike shop will throw a Heli-coil in there for bugger all.

Is there a sump you can unbolt ? Is the engine put together like that ?

Helicoils are easy to install, just the swarf from the drilling and tapping, then breaking the tail off the heli coil might leave a mess in your motor..

I'd like to try DIY first, besides don't think they would have the time to do it before the weekend. Failing that I'll syringe out the oil from the fill hole, it's gotta be better than not changing the oil!

dunno how you're gonna get it out but you'll need to take the bolt/sumpplug with you so that you can measure the thread to find which Helicoil kit you need to buy. Will be around $90 odd for the kit with the drill,helicoils,coil driver. Repco can get them in but often don't have em in stock. I could recommend engineering supplies in wellington but you'll have to find somewhere that does that sorta thing up your way... Barty'll know. Bit scary tho, you don't wanna be leaving swarf inside the case... I don't envy you... good luck

yeah, maybe just tip the fucker upside down and let it drain... Is this on the KX? if so i'd just run it and sort it next week lol. I had this drama on a waterpump a few weeks back... i like to do things at home too but man... i dunno if i'd give that another go lol

Mate--DONT fuck with it. the sump plug threads into the crank case.
Muck it up and youll be splitting the cases
Pay someonle like Alex Gee to do it for ya. it will be cheaper

Thanks for the heads up. Who is Alex Gee?
