Threaded sump drain plug

Hi all, following on from thread in GBC, whats the cheapest way to rethread the thread on the oil draining outlet bit? Usual story, turned wrong way, threaded, now its not a tight seal (in fact barely a seal at all).

Any bodges or cheap fixes to suggest? How easy is replacing the sump with the rest in situ? Am i looking at change from 100? 200? etc.

Theres some sort of special tape designed for this, you put it on the bolt and do it up. Can't remember the name Rolling Eyes

I would probably drill out the old drain hole a gnats cock, tap a new thread and fit a new matching sump bolt, or look into a new sump or a sump from a shot engine.

It really isn't worth a bodge, all it will take is for the bodge to go sh1t shape when riding and the result in an extreme case could be a loss of life, really isn't worth taking short cuts.

I haven't read the other thread yet but if it was me, either new thread in damaged sump or another sump.

Replacement sump or Helicoil/Timesert repair. PTFE tape won't make up for sugared threads, and a sump-full of hot oil being dumped in front of your back wheel is not a good idea.

And if I subsequently come off on your puddle of oil, I'll find you and rip your arms off Wink

As I (and Git) said. Drill it out a bit, then tap it to suit a larger bolt. Maybe something wierd and imperial that is a ballhair bigger than the one you have. If you are lucky you might even find an imperial thread that will cut over the top of the one you have now without drilling.

So either a 13/32" or M11 looking at my conversion chart but don't take that as gospel because I know f-all about imperial threads

Drill= £2
Tap= £3
Bolt= 50p
Taking sump plate off to do it= pain in the arse but not as much of one as drilling upside down into a hole that is dripping oil on your face.

Just an idea but if the bike's dripping oil a bowl of kitty litter under it will stop too much mess (depends where your oil is running to). That's if left outside, otherwise put the drain can there Thumbs Up

As predicted, the bike werent having any of the ptfe tape.

What about that metal hardening paste? If i drained the sump properly and cleared it all around the plug and thread with a solvent and then let it dry?

Or i heard about something called a hex plug (i think)? Couldnt find one earlier, but apparently you just bolt it in and it carves its own thread.

As for the drilling idea... how permanent would that be, and how would i go about doing it? Surely you would need a pillar drill to make it 100% straight?

I am sending off for the sump pan et al, should be here within a fortnight. Just wanted a cheap bodge that will hold out until then. Hell id even consider welding.

Also how would you tell if oil had been contaminated by water? I emptied into a freshly cleaned tub and poured back in. Now i think its on reserves, but it feels like it would if its cold when it was reasonably warm. A slight stutter in the revs. Like i say, like it going on reserves, and it seemed to go away when i switched, but now im nicely paranoid.

So thats 30 quid of oil down the drain too. Happy happy joy joy.

If you were to take the sump plate to an 'old school' engineer/mechanic, they could have it drilled, tapped and a bolt fitted in about 10 minutes. They would also have all the bits to do it with.

It is a six pack o' beer job.

If I wanted that done, there is a little garage in my town, father and son job, who patch up peoples old knackered cars and tractors. They would fix it up for me the same day and charge me a fiver. Find a small, privatley owned workshop and ask them if they can do it for you, if they can't, they probably know someone who could.

If there is a machine shop nearby, it is also the kind of thing someone there could do for you in their lunch hour, ask at the workshop door and pay with beer.
