can't seem to find this - checked the torque values over at old britts - unless I completely missed them...

on the aft side of the oil tank, there is a filter/banjo fitting - thinking it takes a 1-1/8 socket - question, what is the torque value for that assembly. also, the small drain bolt (with copper washer) - torque? I set it at 8 ft-lbs, but not sure it its correct.

thanks....
 
If you tighten both nuts too loosely they will unscrew themselves from all the vibrations and barf oil all over the place.
If you overtighten them the brazes will crack and oil will leak out too.
Try to find somewhere in the middle.
 
I smear Loctite 518 on all sealing washers, like the alloy washers on that banjo bolt. It ensures very small imperfections will seal, even if the alloy can’t deform enough.
30 ft. lbs.
I just pulled that out of my arse, remembering putting it together. Professional mechanics calibrated elbow.

As for the drain plug....
I’ve never used a torque wrench on a drain plug in 50 years.
Google search “3/8-24 torque value”
It’s in steel threads.

...or, tighten 'til it strips, then back it off a 1/4 turn - :D

OK, thanks for the replies, and almost sorry I asked. obviously putting too much thought into this. I guess this is where standard mechanic practices apply - ;)
 
1. Tighten to two farts and a grunt

2. Tighten till bolt snaps then back off a little

equals 4 ft pounds in Mark 3 manual
 
well now, isn't it a quandary to try and torque a very large bolt onto an oil tank mounted with small rubber isolation bolts?
I'm guessing it takes a very soft copper washer and a deft torque wrench. I avoid losening mine for fear of unleashing
an oil leak.

How about Dowty washers? They take very little torque to achieve maximum sealing.

During high school auto mechanics, one of the students asked the instructor "how tight do I put head bolts to?" Nothing about engine model, bolts size; nothing. So, the instructor says "Go as tight as you can, then two more turns". The kid says "Okay" and walks away. All the instructor could do is shake his head.
