Velvet dip stick

I know I ain't too smart at times but I'm wonderin' how a fitting that is always submerged in oil got so rusty that you couldn't fit it over the tube?

No this is on the outside of trans, with the tube on it that holds the screen on the inside of tranny.
Hope that make better sense.
I went back and redid previous post to make it clearer...

1 red - threaded part to lower tran where screen should be
2 blue - part of same fitting rusted
3 yellow - hose to cooler

Well that picture seems to tell me that the same guy that handled your wiring job akso dabbles in plumbing

Here are a couple of pictures showing what the screen and associated parts look like.

We'll call it a typical setup since they changed some over the years, but this came from a mid 80's   10-17.





You need the elbow fitting and depending on what the hoses you have are you may also need hoses to properly mate to the fitting. It's 3/8 male NPT on one end and 1/2 inch flare on the other.

Like you said SkiDim has the parts

They'll sell you some different fittings like part number 122611 and 122711 that will work or you can get their part number 122511 that works in place of the other 2 and is what Borg Warner used..

By the way, did you physically look in the hole to make sure the screen that slides over the tube isn't in there. They tend to stick in there and have to be pulled out or maybe like Duane said, somebody chucked it.

John,
Check the hose end size. It's may not be a JIC-7 but rather a JIC-8. A - 7 will have an OD of 11.5mm (.44") and a - 8 OD will be 12.7mm (.5")

I will take a bright light and look in there for screen.
Thanks Ken for reminding me....

JIC fittings at McMaster

John,
I went to Lowes and my suspicion is correct.Don't even try to use it. Just because the threads fit, doesn't mean it's the correct fitting. Return it the next trip back to the store.
The Lowes fitting is a 45 degree flare

And for another suggestion I'll suggest that you talk to SkiDim about whether you have a need for a JIC 37 degree fitting like Pete thinks or whether the original hose takes an SAE 45 degree fitting

I measured the angle of what was in the transmission and shown in the picture from earlier today and it's a 45 degree angle. mated to an original PCM hose with an Aeroquip tag complete with the PCM part number.. But I'd verify this just to be sure.

Now whether Pete thinks that's right or not, that's a completely different story.

I happened to find a trans Ken worked on where he mixed up the fittings back yard hacking. . I sure hope there's a couple quarts of ATF on board:

That's way beyond my capabilities Pete

I recall only ever seeing a 90 degree coming out of that port on Nautique installed BWs.

We're all used to seeing a 90 degree fitting there Zach.

The discussion is about the angle of the taper on the end of the fitting where the pen in the picture is pointing to.

A 45 degree angle is commonly called an SAE fitting and a 37 (really 37.5) is a JIC or AN fitting..

The JIC is for high pressure hydraulics among other things.

The SAE is for lower pressures.

A B/W transmission is not exactly high pressure hydraulics in action

The regulator in the transmission will keep pressure under 200 psi. Per the B/W installation manual cooler pressure is about 40 psi at 2000 rpm. That's going to the cooler not the higher pressure to the clutches

Maybe with really cold fluid and about 6 thousand RPM you might see 250 ish to the clutches

You could fill a book with info on fittings but generally with the JIC stuff they're made of stainless steel for the higher pressures involved along with better sealing ability due to the angle/amount of contact between the sealing surfaces.

Generally is the key word since you can find either kind of fitting in a variety of different metals

Pete

You have a B/W, why don't you go find that fitting and unscrew the hose and measure the angle.   

It's the same fitting over at the cooler, you can remove it without losing any fluid that way

Couple of updates:

After I got fittings apart here is what I got-



And took advise earlier on Raw Pump brass plate-



Thanks
