How to get fill plug out of AMC 20

Okay, so the time has come for the rear gear oil to get changed, but when I looked at the fill plug it seemed to have a very strange pattern to it. Am I just missing something obvious or what?


Thanks

Sean

Re: How to get fill plug out of AMC 20

Mine took a 3/8" allen wrench. It took awhile to dig all the crud out of it. I then when to Auto-Jerks and got a magnetic fill plug that I could get a Wrench on.

Hope that helps

Be very careful, you will strip that stupid thing out, then end up having to do what I did to get it out...weld a bolt to it. Then throw it as far as you can and go down to the store and get a real plug, you know, the plumbing type with a square head you can actually put a wrench on. Oh, and good luck.

DO NOT strip that thing out!!! Use a manual impact driver to remove it once you've given enough time for PB blaster to do it's work. Dig around the plug with something sharp to give the break free a place to go. I believe it is a hex head of some sort. Get the right one in a socket form (ie one that will fit on the end of a manual impact driver) and hammer away. I've removed several of these on people's rigs and the first was the worst...had to drill the POS out.

Re: How to get fill plug out of AMC 20

i have a better way.. take all the torx out..you'll probably have the use a chisle on most of them... then throw away the torx and put stainless steel bolts in instead. while the cover is off, you can get fancy and tap a hole for a drain plug into the cover

Re: How to get fill plug out of AMC 20

So basicaly, it sounds like I should just take it to a quick lube and let them do it. I don't want to mess around with something like this, especially since I have to work on it parked on the street or an empty parking lot since I'm now at school.

Thanks for the help guys

Re: How to get fill plug out of AMC 20

taking it to quick lube will probably do 1 of 2 things:

1-They tell you they cant do it, mainly because they are afrai to break it.

or

2- They will tell you they will do it and break and then you will have to go through the claims hassle.

What i would do:

Leave what is in the for a few more days, go to a boneyard or somewhere and get another diff cover, very carefully remove the plug (buy a new one) and then if all goes well swap the covers if all doesnt go well at least you dont get thrown out of school for causing a hazard waste spill

Re: How to get fill plug out of AMC 20

The plug isn't on the cover, it's a AMC 20, the plug is on the front side, facing the front of the vehicle. Can I get to it from the inside if needed? What a pain in the ass.

I'm renaming my Jeep: P.O.S.

Thanks

Re: How to get fill plug out of AMC 20

ok this is what you do.. find a 4x4 shop.. or a auto shop.. or a metal shop.. some place with a welder.. go up real nice like and ask them to weld on a bolt to that thing.. if anything.. they will charge you like 5 bucks.. so they can get a six pack on the way home.. then drive home and wrench it off.. and like mentioned above.. put a real plug in that thing.. with the square head sticking out..

Re: How to get fill plug out of AMC 20

The best place to put a drain plug on the model 20 is in the bottom of the casting, just before the lower rib. Use a steel 1/8th pipe plug, with a hex head or a allen head. The next time you remove the cover for service, drill and tap the hole. It makes fluid changes much easier!

P.S. A little liquid teflon pipe sealer on the fill and drain plug threads makes removal much easier the next time, and prevents leaks.
