My "new" axle is missing the axle vent tube. Any ideas how to replace/install one?
all you need is to find a nipple that is either threaded or press fit, that hole can be tapped to thread one into...
My D60 is fitting-less too. I'm gonna seal it up and add a fitting to my diff cover. Not sure why any of the diff cover makers haven't done this already.. but it makes sense to me. Lot easier to add whatever fitting you want to a standard thick-steel cover. Harder to mess with a cast axle housing.
but you need that vent tube fairly high so to eliminate the possibility of it hitting anything and you dont want fuel sloshing up and down the line...
wouldn't that make it more exposed to dammage also??
I think what im gonna do is go to Autozone(or anyplace for that matter) and buy new fittings, as mine are missing them also. Get a larger size, and drill the holes out to that size so theres no sealing problems.
oops,when i read your response i thought you ment high as keeping the breather high.
What are the fittings called? I don't even know what to ask for. I don't want to confirm to the Autozone guy that I have no clue what I am asking for.
i beleive "vent tubes". They should have a big bin full of different sizes behind the counters. Just ask to see their vent tubes, and go back and pick some out...
Although i dont thing there will be much shavings falling into the axle housing, pop the cover off and put a rag over the diff approx under the hole. That way if shavings do go into it, they will be caught, making it less chance to mess something up, which i dont think much will do anything. Squirt some diff fluid over the diff and everything if your concerned.
When you go to tap the hole,grease the sh*t outta the tap, it should trap most if not all the shavings.
The vent tube on the axle I just rebuilt was completely rusted away.
I drilled it out, cleaned out all the pieces and then tapped it to 1/4 NPT.
After that I just threaded a hose barb into the hole and away I went!
Ive heard of this, but i dont have any knowledge about NPT or anything of the like. Could you point me in the right direction on doing this?
NPT is just National Pipe Thread. It's just an identifier.
There's no big voodoo to it. You just drill out the busted vent tube to the proper size (7/16" hole for 1/4 NPT threads) and tap threads into the hole. Same as tapping any other threads.
The stock tube is pressed in, so you don't even have to worry about any existing threads.
mine was completely rusted and broke off. i used the drill and got as much out as possible and used a magnet to get the shavings out. then i tapped a new hole and put a new one in. problem solved. i dont know what the threading was, but i didnt care, im not planning on taking it out ever again. i used sealant just to make sure it had a good seal as well.
