I just looked at several of my posts from weeks ago and it's there.
A little "x" in a box at the far right hand side of the screen.
If you hover on it it says "delete this post".
Yeah pretty weird, it's on my most recent post but none of my previous posts. Probably a glitch in the forums older software.

Hey Tom,
I have an extra new Weatherhead 602x3 brass T for the bellhousing if you need one.
Payback for the gasket you sent me.

It looks like the vent line is suppose to tie into the bell housing where the plug is installed just forward of the clutch boot. I'll have to modify this.

Exactly Wes.
Two female 3/16 inverted flare over a 1/8 male pipe thread.

That's odd? The M38 ORD 9 lisiting shows part number 143481 on page 32 which lists the fitting as "Tee, flared tube, inverted' brass, 1/4" tube, 3/16" tube, 1/8" male pipe side." Note the two female ports are different with one being 1/4" tubing and the other being 3/16" tubing. Yet there are two listings for each of the two tubes under the vent system 1st listing is Line Assy's and the second listings read Tube Assy's but both are about the same length and diameter 3/16". Looks like the Army listed the wrong T fitting in the Ord 9. _________________ Wes K

I believe the "T" (PN 143481 Pg 32 of ORD 9) actually has two female ends and the base leg end is male 1/8" pipe thread.
Thanks Wes. I found the info and diagram in the Refernece Book as well, I have the Tee fitting on order and will add that into the vent circuit as soon as it arrives.

I agree. The ORD9 has a typo.
And from what I can tell, there's no such T made with 3/16 inverted flare on one side and 1/4 inverted flare on the other.
Every T that I found in the Eaton Weatherhead catalog has both sides the same tube size.
Pretty sure the Eaton-Weatherhead 602x3 is the correct T for the ORD9 143481 ---> 3/16 x 3/16 x 1/8
I looked again at Tom's photo and it looks like maybe he plumbed with 1/4-inch tube instead of the 3/16's tube called out in the ORD9.
If that's the case, the T he needs is 602x4 ---> 1/4 x 1/4 x 1/8, and I don't have one of those.
As mentioned above, I have an extra 602x3 if he wants it. _________________ Ron D.

Thanks Ron, really appreciate the offer. Like you noticed the previous owner used 1/4" tubing. I have a 1/4 x 1/4 branch tee on order, hoping it will arrive this week so I can get it installed and get the floors back in.
Tom Explained the piston's origins on the M38 facebook page:

John Andrews Yeah pretty wild, I have no idea how they got bent that way. The piston is out of a 1956 Ingersol Rand KVS. A single turbo V6 that produces 1000hp at 330 RPM. Used to compress natural gas. I maintained and rebuilt these units for years. Bare piston weighs 400 lbs, makes a great vice stand 👍.
Good eye, that's a restored 69 Z50 that I did years ago. "

Thanks Wes. Sorry for the delay.
The power piston is out of a 1955 Ingersol Rand KVS Engine/Compressor. The engine is a single turbo natural gas fired V-6 unit that develops 1000hp at 330 rpm and drives two double acting integral compressors that are used to pump natural gas. This piston was changed out due to exceeding out of round specifications. Bare piston weights 400 lbs and the valves have a 1" stem.
The piston has two threaded holes in the dome of the piston used to remove the piston from the liner, I fabricated an adapter plate that bolts onto the piston using these holes and allows me to bolt the vice onto the plate.....Bam vice stand. The piston works great as it's heavy enough to hold the vice in place but easy to twist and "Walk" the assembly around the shop as needed.
Just your standard Chevy 350 . The lifters are hydraulic and a single head weights about 700 lbs.

Vent line modification. When we purchased our M38 the vent line going from the trans/transfer case to the vacuum pump wasn't tied into the bell housing like it was suppose to be. With the floor panels removed now is the time to modify the vent line and get it tied back into the bell housing.
Brass inverted flare branch tee. This is installed into the bell housing.
Marking out the bend location on the tubing.
Making up the flared ends on the tubing.
I made the tubing fit up tight to the case so it wouldn't stick up and interfere with the floor panels once installed.
Now to bolt up the floor panels.
I had ordered new (reproduction) shift boots for both the transmission and transfer case. The aftermarket transmission boot was very high quality and just like the original, the transfer case boot was thin and cheap feeling. I tracked down some NOS transfer case shift boots from Dan at Classic Military Vehicles. The NOS units are nice and pliable and look like brand new, they also fit and look correct. I picked up a couple extra to store away in the parts bin in case these eventually fail, but since the Jeep is stored indoors and out of the sun they should last for years.
Floor panels re-installed.
Getting closer to being back on the road again.....soon!
