Torque converter bolt torque talk

[Demon James]

Hi all, hope you are managing to get out and about in this cruising sunshine I had a loud metallic knocking this week and found a bolt half out on my flex plate. The bolt was a stainless steel one and it was too long so appears to have reached the torque converter before tightening fully on the flex plate. Anyways, its stripped so ive successfully installed a helicoil and the correct bolt and loctite the info i've got says to torque them up to 270 inch pounds but I come up with different numbers when I convert it to Newton meters or foot pounds as thats all i have on my tourque wrenches. Now I accept I might be being a bit thicky McThick from thickshire but can any one Oh and the second photo show a missing bolt from the engine to bell housing I presume there should be one

Photos are the wrong way round first one shows empty bolt hole

270 inch pounds is the torque you'd get by resting 270 pounds on a spanner one inch long . If the spanner was a foot long you'd only need 270/12 pounds on the end for the same torque = 22.5 foot pounds

So just divide by 12

Or , if you want to think the other way round, 270 inch pounds is also the torque from resting one pound on a spanner 270 inches long . 270 inches = 22.5 ft , so it's 22.5 foot pounds

They don't need huge torquing, but do use loctite or they'll work free again.

I only had a 271" long spanner so I've just been into the garage to cut an inch off it.
Only problem I have is I have to dig a 25 foot hole under the car so that I can use it.

If the bolt was too long then I doubt the head will be the shallow head type needed.
A normal height head on the bolt will catch the block at times.

if you want to set the talk correctly you had better get hold of raymond he is a master of it,

The ball joint splitter worked then James?
You don't mess about getting stuff done do you.
What was inside the sump, any nasties??

Cheers guys as ever Doh I was being a right plum, i did the divide by 12 one first but tried to back it up with the converter on my phone. Problem is i was using newtons and pounds of force not Newton Meters & foot pounds. 30Newtons came out as 6.7 Lbf! Cheers for the splitter Matt I'll drop it back before I go away, unfortunately it didn't fit so I saved the thread tips with an old castle nut and convinced the tapers out with a "tool for all" hammer The leaking rad didnt survive the sump removal as I had to move the trany fluid pipes which only exaggerated the botched (by others ) joint repair so its off to the mender mans Still, should start chucking it down ready for when I'm finished I suppose I should have bored you all to tears with my work so far before Robtwin or Stu tell me off for being too shy at the next Hooks Cross eve
