Helicoil fitting - Nottingham

[Jimmy5]

I need a helicoil fitting to a stripped sump plug can anybody recommend a place in or around Nottingham that could do such a thing?

Also what are the chances of it being done in situ or will it be an (motorbike) engine out job?

[GreenV8S]

If there's enough access to get a tap in position then it would probably be possible to do it in situ, but tapping a hole that goes through to the sump obvious will leave swarf in the sump unless you find some way to contain it. So most likely you'll be told to take the sump off before it can be repaired.

I always put plenty of grease on the tap to catch the swarf, and I do it a little bit at a time, taking the swarf off as I go, it would be better with the sump off though.

Thanks for all the suggestions so far

Problem is, there is no sump the drain is in one half of the engine casing so would require full strip down and rebuild

You would need to see how bad the damage was, but is there any prospect of repairing it with a thread repair tool? This sort of thing would enable you to repair it in situ and contain the swarf for you:

I assume the sump is alloy, how thick is it? Also, what thread size are we talking about, metric or imperial? I know a guy in Long Eaton with his own engineering firm who could do it and he's into motorbikes.

Most of the thread has gone. Shame, as it looked to have been the ideal solution

Yeah its alloy. The thread is about 20mm deep and theres plenty of metal round it to drill and re-tap. Size is M12 x 1.5

I'm pretty sure the engine will have to come out as its tight for space between the back of the engine case and the frame. Just hoping to keep costs down by not having to rebuild

what bike is it?
just wondering if it'd be cheaper to buy a second hand engine as some go really cheap these days from breakers.

Hi
Cromwell tools sell complete thread repair kits inc drill, tap, helicoil tools and helicoils Order code: KEN-621-1490K that come in at £34.86 incl. VAT. It's relatively simple job but as you say may require engine out.

Alternatively, if the thought of stripping the engine is putting you off presumably it's not anything particularly previous, how about bonding in an M12 sleeve internally threaded to say 8mm and use any convenient M8 bolt as your sump plug?

A quick update:-

Got the heli-coil fitted by SEP engineering of Kegworth for a far from unreasonable £20

Which leaves enough money in the bank to buy a decent torque wrench to stop it happening again

Good god, these people are right on my doorstep and although I knew they were there I didn't realise they worked on engines.
Thanks for the update. I'll certainly put them on my list of people I need to know.
