vent lines

I have an 83 CJ7 with stock axles. The rear has a fitting that will work for attatching a rubber hose to extend the vent. The front on the
other hand just has a hole in it. It isn't threaded or anything. Should I thread it or get a fitting that presses in there? What has
everyone else done?

Re: vent lines


When I bought my CJ7 and finally put it on the road 3 years later I had noticed my vent was broken off the front pumpkin. What I did was go to the nut and bolt store and get a 3" (I used grade 8) bolt and nut, also get a tap and drill bit. I brought this stuff home and cut the bolt down to a size I could work with and then drilled a hole thru the center, drilled the correct size for the tap in the old vent hole, tapped it out, installed the bolt and locked it down with the nut and wha-la a new vent tube. you might have to increase your vent line size but thats about it. Hope this does it for you, later.

Re: vent lines

I had the same thing with my original Dana 30. The fitting that goes in there is pressed in and it is a pain to install. The problem is that the way the tubing is bent you can't put equal pressure all around it to press it in. I worked and worked to get mine in and finally got it done. If I had to do it over again, I would drill and tap the hole for a pipe fitting with a barbed end to attach a rubber vent line to. Of course, I would do it at the same time as a fluid change to make sure that none of the filings made their way into the gears. If you want to try and press one of the original type fittings in, send me a private e-mail and I will send an extra one to you.

Re: vent lines

I put a brass hose barb in the hole on mine with Loctite Weld (same thing as JB Weld). A year and plenty of hard wheelin' later it's still holding up.


Sometimes it is easier to beg forgiveness than get permission.
