3406E Jake Housing mounts torque specs

Hello friends,
First time poster here. Was wondering if anybody can confirm if I have these toque specs correct. I am doing some fuel injector and electrical diagnostics and just put it all back together under the valve covers. My Jake housing on the 3406E (6TS) is 340A. I have 4 mounting bolts and 2 rear nuts (pictured below). I know these all have different names, but to avoid confusion I am mentioning placement.

I believe they all torque down to 80 ft lbs, more specifically 50 ft lbs - 1/4 turn - 80 ft lbs

And the valve covers bolts along with valve cover base 13 ft lbs.

Also notice the one mounting bolt is a different diameter? This is the only model I’ve seen this on, anyone know what that’s about and if it’s torqued the same? I would think so. I’ve circled all mounts, the orange and red is the smaller diameter bolt. I believe it’s 5 or 7/16 off the top of my head and the rest are 3/4” and the nuts are of course larger.

Thank you anyone that has any input!

 

The different diameter is just the 12point head and fits approximately a 13mm socket. It’s the same under each cover so it doesn’t look to be a replacement of any sort.

I called a CAT shop and that’s where I got the 80 ft lbs from and they sent me a snap shot of the quick guide which had me confused for a moment. Anyway I tightened all down to 80 and honestly when taking them off they felt way tighter.

And after all that I must have messed up setting the housing back in, looked to all be lined up, but the engine is turning but won’t fire. So now I have to start over on that or do an overhead.

Never done any of this before, but it seemed simple enough. I took my time.

 

Thank you for that info. This actually came to my mind late last night and I’m about to go try that. Hopefully turning the engine didn’t get air in the system. Had that happen once and took an entire day to get it all bled out. Hopefully that’s it I was beginning to wonder if I somehow mixed up the order of the Jake housing. I had it all organized, but it was late and I may have overlooked that
