It helps you receive more accurate answers if you identify the make/model of the vehicle you are asking about. This is easily done automatically by simply adding that information to your signature element at the end of your post.
Using the correct service pubs and parts listing is very important as is occasionally referring to the civilian jeep manually that is most equivalent to your make/model jeep. Often times the civilian manual which is meant for use by both mechanics and owners will have more detail on certain procedures.
1 - And as is the norm all surfaces need to start out clean & dry.
2 - Make sure you pean the existing bolt holes in your pan back outward so the edge of the pan is perfectly even/flat.
3 - Follow directions in service manual for installation If sealant is required it will be mentioned. It is seldom used by pro's unless the manufacturer's data specifies a need for it. It makes the seal to pan surface slippery allowing the seal to migrate outward or inward during tightening which leads to unwanted leaks. Sometimes there will be light damage to either of the metal surfaces that will not clean up smooth. It is common practice to use a drying sealant or epoxy to smooth those out.
4 - Bolt tightening sequences if critical are usually published in the service manual. If nothing is published then the industry standard is to insert and snug the bolts in a diagonal crisscross then go back and torque them in a similar crisscross. _________________ Wes K

Differences in equipment are one reason it's a good thing to ID the vehicle you are discussing. Another thing is to help folks offer you the appropriate manual selections that may help.
The main problem with the old Army manuals is they are written on the assumption that they will be used by trained motor pool technicians. To get why and how answers from them is virtually impossible. One would have to review a motor pool technician's technical training course text books for these answers.
With the M38 the appropriate manual selections for this issue are the TM 9-1804A
This is all the Army thinks it needs to tell you.
Then you go to the index and look up "Torque Specs" Ahhh Page 121 Par 148 & 149, great.
Page 121 has NO TORQUE SPECS nor are any torque charts found anywhere in this manual!
Let's take a look at the Civilian Jeep service manual for the CJ series early (Up to 1964):
Voila, they even give the torque specs here. A note of caution here. This paragraph assumes the engine is on an engine stand and inverted so all you need do is lie the oil pan on the bottom of the block.
