I just tried to do a sreenshot at Ronnies on PC, and it asked to cut out. In the past when trying to copy and paste text a message would pop up. Now you can do that too. Not sure the site or new version of windows, or browser. But either way, I said to go look at it yourself. So I really don't care.

You must be doing something incorrectly. I am on a computer and just saved the image using the right click feature and took a screen shot and saved it.

Your attention is invited below to the posted images.

Additionally, you can go to the H-D parts lookup and it is easier to look for parts and download images with the right click feature:

Your welcome, have a nice day

Yes it will now allow me, even lets me to draw a border around it. In the past a pop would come up on the screen. I used to try and copy and paste parts numbers when building spreading sheets for big jobs.

If they are the type of thread that is NPT, wouldn't they seal without tape or goop, meaning it is just loose, causing the weep/leak?

Big bleeping deal ladies
Who you calling ladies, you FN kunt. You were wrong, always wrong. Can’t shut up as asked let alone proven to be wrong in all that you say.

Everyone knew it wasn’t an oil cooler. You’re trying to deflect and still talk game. Then your bitchass calls us ladies?

F you and the forum mods that won’t ban your sorry *** for life.

You ruin everything about this site. Everything.

(I will get an email saying it wasn’t nice and my comments removed and this F will still be shitting on threads, good and bad ones.)

Tape/sealant is mainly to prevent galling of the threads. NPT usually will seal themselves; however, they can cause damage to the female side on the aluminum case as stated above, too tight and you can crack the case.

In the picture it probably is not tight enough but if you tighten further the angle of the fitting may be in the wrong orientation. If you are not going to use OEM parts, I would put a straight fitting in there so I could get it tight enough, a short piece of tubing, then a 90 tubing fitting with the rest of your hose running to the oil cooler.

The fitting is 1/4 npt. In an ideal world, they wouldn't leak but this world ain't ideal. You could remove the hose and try to get another turn on the fitting but I'd suspect that you should add a little pipe sealer. Tape is generally frowned upon but it can be used in a punch. The reason is the paranoia of having the tape get inside. When doing so, I start the tape about a thread back from the end. This will keep the tape from getting inside but if it's ever removed, you need to take care that all the tape remnants are removed.

Yes threads into case are NPT. Get rid of that 45deg angle hose barb adapter and use straight. That connection should not be used as an oil cooler connection. Seal pipe threads with loctite pipe thread sealant. Use OEM hoses as shown in diagrams. Other ends of hoses connect to like fittings in transmission case. Internal passages in transmission case go to oil pan. Lower hose is supply from oil tank to oil pump. Upper one is oil return to tank from oil pump return side. Use proper clamps, not worm drive. You can use some dulled nippers to tighten the clamps if you don't have the tool.
If you have a oil cooler, it should have an adapter connection at the oil filter mount

So it seems if I disconnect the hose, snug the fitting, which turns with a finger now, re-attach the hose on the other side of the cable below, it should be good?
