Basic Maintenance-removing shifter knob
 
Since Mean Max pioneered the "Basic Maintenance" series of threads for the YJ Forum, I figured it best to keep the trend going (or should this be "How To" ?). This particular chapter may be felt to be rather weak, but I have seen a number of posts asking about this, with stories included about busting off the threaded portion of the shifter shaft by brute force, etc while trying to twist it off the shaft.
Removal of the shifter knob or reorienting the knob so the shift pattern doesn't read upside down or sideways is pretty straight forward. This of course can be done in the Jeep, I just took mine off so I can take better photographs for demonstration purposes.

The technique is identical for the shift knob on the Transfer case shifter.

The goal is to get from here:

There is a jam nut, or locknut if you prefer, that locks the knob itself onto the shaft once the knob is threaded on. The Jam nut has 2 flats cut into it that a 3/4 open end wrench or a medium sized adjustable wrench will fit across.

You need to un-Jam the nut by turning it clockwise down the shaft (as if tightening it) away from the bottom of the shifter knob, while holding the shifter knob still, and/or turning the shifter knob simultaneously counter-clockwise. If you find that your Jam nut is tight against the shoulder on the top part of your shifter shaft, then your goal is to hold the Jam nut still with your 3/4 open end wrench, while you can then turn the shifter knob counter-clockwise/lefty-loosey up the shaft.

Installation is the classic "reverse of disassembly" but I suggest as in all things Jeep, put a dab of antiseize or bearing grease on the threads. This does not take a lot of force, but consider a squirt of PB blaster first if you find things rusted or frozen. Re tightening the Jam nut also should not require a massive amount of torque either, just thread the jam nut to about a half turn above the shoulder on the shaft at the bottom of the threaded portion, spin the knob down to it, then hold the knob in proper orientation shift-pattern wise, while tightening the jam nut up against the base of the shifter knob.

nice write up. i took mine off a couple days ago to extend the shifter a littler. cost under $2 bucks:thumbsup:

Good job. I could see how some might think this is VERY basic, but like you, I have noticed that others are having problems with this very thing. I suppose most assume they are one piece and end up jamming the jam nut farther into the knob.

Excellent information! :thumbsup:

I think I have an old shifter laying around with the threaded portion busted off. I planned on doing a "how-to" thread on making a repair for that, but I think everyone will be best served by my incorporating it here in this thread, as long as it's okay with my good pal Opihi59. :D

Max :cheers2:

Max--by all means, add it in. It will make this thread more complete.

In addition, there is a shifter "extender" available thru places like Quadratech that screws on to lengthen your shifter like for folks with a bodylift. If I just had a lathe laying about, I could make my own. This is one version: RockNob 3/8X16 - Rocknob Shift Lift 3" Shifter Extension in 3/8" x 16 Coarse Thread for 76-95 Jeep® CJ-5, CJ-7, CJ-8 Scrambler & Wrangler YJ - Quadratec

Is this the same process necessary to remove the 4WD shifter?

From the first paragraph of the text, post #1. Yes, the technique is the same for removing the shift knob on the Transfer case (4WD) shifter.

If you are removing the shifter lever itself, I have another thread in the FAQ covering that topic. It is in this thread:
http://www.jeepforum.com/forum/f12/s...hifter-513891/

Please let me know if you have any further questions, or run into problems when you do this. :thumbsup:

Max,

Ever get around to that repair for the busted of thread portion someone (a friend of mine, definitely not me) :o broke the threads off their shifter yesterday

Thanks!

Mike

Good thread, Only a idiot would break the bolt taking the knob off. Impatient dolt!

I did it myself about 5 years ago, and was so mad at myself for doing it. After I broke the bolt I just sat there wondering how I could do such a dumb thing.

Now I just laugh about it. Good write up, Thanks Opihi!

Anyone know where to get the shifter knob jam nut? My transfer case shifter didn't have one when I bought it.

-Cheers.

I've passed a few up on Cherokees in junkyards in the past, shoulda scored them when I had the chance. You can pursue this option if you have a JY nearby. Otherwise, go to your local specialty hardware store, and get a 3/8 X 16 Jam nut. It is half or less as tall as a regular hex nut, and it will work fine until you come up with the proper part, or you may find it will do so well that you won't bother to swap it out later on.

You can see what I am referencing when I use the term Jam nut versus a regular Hex nut. They're cheap, the price shown is for 100 pieces. You should be able to come across these at any good hardware store.

Thanks for the info. I was thinking of just grabbing a jam nut at work, but was hoping for an OEM matching look to my transmission shifter. I'll hit up the junkyard soon and hope I find a 5sp Cherokee.

Hmmm I may have run across one of those broken thread issues. I took my t/c aftermarket knob off and there are some crappy 1/2" threads on the shifter. I guess the PO broke it and used a die to cut the new threads. I just bought 3/8X16X2" extensions and I was surprised to see the bigger threads. The 5 speed has a Hurst T handle shifter of all things and the jam nut is so far in I cant catch it with a wrench. Jeez the PO f#@*ed up everything he touched.

Opihi59 09-20-2012 10:38 PM

Well, if someone wants to send me a shifter with a broken off threaded section, I'll fix it and do a writeup on it, and mail it back to you fixed. How about it?

PM me and I'll send the address, and I'll even show you my thread in the FAQ on how to remove the shifter shaft from the shifter stub so you don't have to mail me the whole tranny. :thumbsup:
