A 833 - How tight should the fill / inspection plug be ? does anyone recommend using the white plumbers tape on the threads ? thanks

ps , while we are at it , what is the spec for foot pounds on the rear axle fill plug 8 3/4 sure grip ? i can't seem to find either .

PST592 liquid thread sealant.

As for tightness, they are tapered pipe threads so need nothing more than snug.

I like dry and 30 ft Lbs. As said it's pipe threads, it's not going to fall out or vibrate loose.

When you have to pull hard with a long wrench that is way too tight.

Tight enough not to leak is pretty much my plan. Pipe joint sealer is probably a good idea.

The PST592 performs 2 functions; keeps it from sweating, and acts as an antiseize the next time it comes out

I use teflon tape, get it pretty tight.

I went to mechanics school and worked in dealerships and shops on mainly American cars. I've never seen any new car have sealer on these plugs. I've never read in a service manual to put any sealer on these drain/fill plugs.

How many leaks do you see on these? Not many.

Now you could use it as it won't hurt anything.

Now the Teflon tape is a real bad idea on a transfer case as many of them have an oil pump inside and you wouldn't want to plug that with the fragments of tape.

NPT threads in general need a sealer, just because of the form of the male and female threads. If you’re careful you shouldn’t get any inside. The case isn’t under pressure so less critical.

I have had problems sealing up 833s in the past so maybe I’m over doing it on the plugs. Since I started getting the right parts from Brewers and using the right sealers, I don’t have any leaks.

Auto manufacturers warranty their cars against leaks and they built multiple millions of cars with no sealer on these NPT oil drain/fill plugs. Good enough for me because. mine don't leak either. LOL

If YOU need think they sealer, well then they need it

If you crack the case its too tight !!
