Nss Help

[yxmj]

Son started having no back up lights....by wiggling the shifter (auto trans) we could get them to work sometimes so we figures it was the Nuetral saftey (back up switch).

 

He found a nice write up on a cherokee forum on how to remove it and followed it....it was when he could not get it off i became involved....from what i can see he followed the instructions to a tee.

 

I can get my fingers on it and get it to wiggle but for the life of me can't get it to slide off. It seems to me i removed and cleaned on of these about 5 years ago and from what i recall it was easy and fast.

 

What are we missing.....anybody have advice or tricks? . :MJ 1: .  THANKS

I just pulled one of these off a Cherokee at the junkyard.  Since it's been awhile...and I did not have all my tools...I knew just sticking a screwdriver under it and wanking on it wasn't going to work...so I used a blade ON the threads and slowly (not a lot of force) pried it far enough out to get my fingers behind it...then I just kind of finessed it off.  Hard to explain, but you can't squeeze the threaded part, and you can't whack it from the other side.  I'm sure a little PB on the flat part of the shaft might help.  The one I removed was greasy as hell, so it made it a little easier.

Clean all of the shaft you can see with fine steel wool or the like. Use lots of penetrating oil. Get 2 shim shingles and tap one up under each side of the NSS carefylly.

Thanks Gentlemen

 

One thing that I forgot to mention that would not be a problem in Prescott or Paradise is that i was attempting this maneuver laying under the truck in the snow with the outside temp at  -7 Fahrenheit. ( so the bare finger trick only lasted till they froze  :yes: )

 

So here is my "New Trick"   I took 2  5/16 flat washers and welded them offset all the way to one side to 2 small chunks of steel rod. This allowed me to work one washer in and pry on the rod till i could get the other in. Worked them around until they were across from each other and pryed suddenly ...pop...off it came.

 

Giving it a soak now and will give it a clean to see if it can be re-used ....if not Parts Source is open till 5

 

Thanks again.   . :MJ 1: .

Just as an FYI...do the whole disassembly/cleaning on a big piece of carboard or on a cleared off work bench.  The springs that hold in the two removable contacts tend to get lost, and they are a $#%&@ to find, or replace. I've done the cleaning/disassembly a few times, I got overconfident. Luckily for me I had 2 NSS's to work with...but somewhere on my gravel driveway is a tiny spring that I can't find.

 

:doh:

Thanks for the tip PMJ.....having lost a few small parts in my day I was all ready set up similar to what you described.

 

Another removal tip.....the switch we took off in the JY was off a trans that was out and easy to get at so we could experiment. My son found a posting on a cherokee site that worked but I would have one comment.

 

Take out the adjustment (small) bolt first.....go heavy on the penetrating oil on the shaft and the large nut.....now un-thread the nut just enough that you can slip a large flat screw driver or prybar in and using the lip of the trans (were the pan bolts up) as a fulcrum....CAREFULLY pry it off....the one part I would add with this method is that you would run the risk of breaking one or more of the 4 threaded "Teeth" that the nut holds to the shaft....we were lucky....

 

All lights work.....as well as the neutral saftey......and it might be my imagination congratulating me on a job done....but i tink it is faster to catch when starting too???
