Yes I know I'm a pillock. Cracked sump MK 2 -Update-

[Visitor Q]

Ham fisted people and sump casings, not a good match. (Voice of previous experience)

Went to undo bolt, felt tight so had a go or two, then double checked direction to undo it. Had it wrong

Undid it, drained it, went to put the bolt back in. First bit of pressure ... *crack*

See the attached picture for what appears to be a minute hairline crack (only noticeable when the bolt is in, so its obviously allowing it to expand a tad). I'm thinking a fresh washer on the drain bolt could be helpful anyway as I've been using the same one for 3 years ().

But... Could I just wait for it to all drip out fully, clean it with petrol inside and out and;

1- Cover the bolt in liquid metal, thread in, remove and leave to dry.

2- Cover the bolt in instantgasket and thread in, and leave in.

3- Combination of the two.

4- Just thread in the bolt with liquid metal and hope you can get the sod out afterwards.

The problem is;

A) Most importantly, last time I killed it and had to get the sump off I fubared quite a few bolts, and ended up leaving the stumps in. It's sealed ok this time, but I wouldn't trust it that much.

B) I start work on Monday. I've only planned on using the train for a week, but I'll get very limited time to fit a new/fixed sump if I get it helicoiled/replaced

C) My bike is in a state of unhappy harmony, taking things off and reattaching them may be impossible with certain components (mainly exhaust).

you "may" get away with using liquid metal (unsure)...

but you'll be really pissed off if the bolt decided to fall out and dump all your oil just in front of your rear tyre....

personally i'd go for another sump

The crack could grow and like nitemare said you don't want it loosening up and chucking your bolt out. I've no idea if liquid metal will hold.

I'd take the sump off and either drill and weld the crack properly or replace the whole thing. Perfect time to drill out and replace the bolts you bodged the last time.

Get it welded up, same thing happened on my last sump, got it ally welded + helicoiled for £20

[binge]

I cracked the sump on my NC29 when I did it back up. I just slapped a bit of the old chemical metal around it. And it was fine. It used to seep a tiny amount of oil. Not even enough to cause it to drip though.

I changed the Sump in the end.

as it sticks out, Id say you have 2 options.

1) liquid metal and a small jubilee clip over the top clamped damn tight.

2) get it off and get it welded.

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance.

So instead of changing a .30p washer you need a new sump at how much?

Guessing they didn't teach you any maths in your degree then?

Change the sump before you come a cropper.

When I had the NC29 and the NC30. I was friendly with a few racers. Who had 100s of parts in their garages.

I used to get things like Sumps, For like £10 posted.

I'd have a scan round the racing section, And maybe ask around on Visor down, If you can find somebody who races CBR600's, Im sure you will get a sump for less than £80.

Anyone got any tips for using liquid metal? What to clean the surface with, does it need heat, should I do inside aswell etc?

To use liquid metal, araldite etc. it needs to be completely clean. Use Ispropyl alcohol available here https://www.maplin.co.uk/module.aspx?moduleno=28994

Clean your sump plug and put it in to open the crack slightly. Then clean the crack and force in your liqud metal. Then take the bolt out and put a good quality jubilee clip tight around the cracked stub and leave to dry. Once it's dry, put your sump plug back in with a new washer and don't overtighten. Leave the jubilee clip on the stub.

That would get you by until you get a new sump.

That helps a bit. I assume its file the crack a bit deeper in essence?

I've borrowed some files from a mate, and his isoclene. So thats that covered.

Just need to get some liquid metal and a new crush washer and I'll get to see how irritating this mistake is

The idea about drilling the crack before you fix it is because sharp corners concentrate stress and help the crack grow. Drilling it and giving it a round spreads any forces out and helps prevent it happening again.
