82 Katana 1100 oil drain plug specs?

[johnod]

I cannot seem to find a torque spec for the drain plug in my maual.
Does anyone KNOW what it is?

I've tightened to 7 ft/lbs with new washer and it still seems to drip.

Any ideas?

Thanks

Hi John, yeah 7 is way too low a torque setting for the sump plug. Looking at my manual it doesn't have a torque setting for the sump plug however, it does have the torque settings for bolt and nut sizes not mentioned in the servicing list.

10mm conventional bolt "4" 16 - 25.5 lb-ft
10mm bolt "7" 29 - 43.5 lb-ft

12mm conventional bolt "4" 25.5 - 40 lb-ft
12mm bolt "7" 50.5 - 72.5 lb-ft

14mm conventional bolt "4" 36 - 58 lb-ft
14mm bolt "7" 79.5 - 115.5 lb-ft

16mm conventional bolt "4" 58 - 94 lb-ft
16mm bolt "7" 123 - 181 lb-ft

18mm conventional bolt "4" 94 - 137.5 lb-ft
18mm bolt "7" 144.5 - 202.5 lb-ft

Hope this helps, cheers.

Thanks for the info, I'm not sure if it is a conventional thread, those numbers seem pretty high to me.
I got the 7ft/lbs figure from an online manual for a 1980 i think.

Anybody else want to weigh in on this?

I can check tomorrow.
IIRC, it is low as the bolt threads into soft aluminum, 7-8 Ft.Lbs.

I always quench it 'til I see a drip of water, haha.

Just a thought, when you remove the drain plug check to make sure the old copper seal is completely removed from the backside of the bolt head. Somethimes they get so squished it's tough to remove them, & it almost looks like it's part of the plug.

Verify the mating surface on the pan side is gouge free too.

Shouldn't take too much torque to tighten it up - once the new seal is compressed just snug it up.

7 ft/lbs is what my service manual says. And I've got the all the supplemental manuals as well.

Thanks for the torque setting Greg, for some reason my manual doesn't list the sump plug in the Torque Section. I'll write this gem of info on the list, cheers.

Thanks, I'll also write that down.
Now i have to figure why it leaks at the correct torque.

I had the same issue on my Kat with an 1150 engine...
In the end I discovered that the lower part of the sump had developped a small hairline crack
I'm sure this was the result of poor handling when the engine was removed from the frame ( by the PO!)

Then, does anyone need an oil pan?

The sump plug which is a 14mm thread screwing into aluminium has a torque setting of 14.5-18.0 lb-ft.

Where did you get this figure from?

We've got a 7 figure below from manual.

Beam-type torque wrench right about the time that the pan stripped?
