Torque converter cover bolts

[Aidan Pryde]

Hi guys,

i found out, there are two bolts missing on the bosses on my torque converter cover.
Does anyone know the right size of these bolts and what they are used for?
Found a picture on google:

Maybe there are some more parts missing, like a bracket for fixing the cooler pipes or something?

So long
Knut

You are correct about a clamp that attaches the transmission cooler lines in place. The correct bolt size is 7/16" 14 threads per inch. Hope that helps.

Hmmmmm.... the bolts to hold my dust cover onto my K-case 700R4 were metric M10-1.5. At first I thought they were 7/16-14 SAE and these would start and turn for a few revolutions but then become thread-bound. The M10-1.5 metric bolts were correct. In addition, the bolts holding the transmission onto the engine block are also M10-1.5.

Parts TM shows, MS90728-83

not metric

Maybe the key to your statement is 700R4?? As far as the engine/trans bolts , I've only seen SAE used. Who knows what has happened to these trucks over the past 30 years!

You are correct. The cover on the flywheel to transmission are M10 x 1.5 metric. The clamp bolts on the bottom are 7/16" 14. The bell housing to block bolts are 3/8" 16. They did a whole mix of metric and standard on the drive line. The water pump has 5/16" 18 nuts holding the fan clutch on. Just get out the entire tool box.

I´m a little confused now. So these bolts really are used to hold the cooling lines with some sort of clamp?
But doghead posted they are not used on the cucv, just a few minutes after i started the thread? Dogheads post seams to be deleted now, hmmm.

Anyone has a picture of this clamp attached to the lines and the cover?
I guess i have to build one, because getting such parts here is not that easy.

I'd just make one from a piece of sheet metal, just make sure you slip a piece of rubber hose over the steel lines where they touch and are clamped to keep them from vibrating and wearing a hole through them. I speak from experience! You never leak out ATF when you have a spare quart or two

I was in the John Deere place a while back picking up some parts for my mower and saw that they offer those clamps in numerous sizes. Probably because tractors have hydraulic lines running everywhere. There were boxes of different sizes on the shelf. Nice plated clamps with the rubber insert. So maybe you should look there.

Hope this helps.

If you look back, I deleted my original post because I realized I was thinking of something different(I was incorrect).

The P clamps are listed in the -24P(parts TM). As well as the bolt that I supplied a link to.

I was out playing in my barn most of the day and thought I would take a few pictures for you. This is the original clamp and cooler lines. This is how they came from the factory. I hope that helps. And the fact that they are clean and painted helps you see the detail of each part. Happy Holidays.

Thanks! Really nice pictures! I thought my workhorse is kinda clean from below, but wow! That´s what i would call showroom condition.
So, if just such a small clamp needs to be fixed, i´ll reduce the thread with a threaded insert (Ensat) to metric M6 and use a rubber insulated stainless cable clamp to fix the lines.
