Title: Stupid question... But where is it?
Post by: jfrabat on April 01, 2014, 08:05:02 AM
OK, I know I have changed this in the past (some 6 or 7 years ago; the time I changed it after that was done by the mechanic, as the Jeep was already in the shop), but I do not recall where the heck the Oil Pressure Sending Unit was located.  I tried looking in the FSM, but I did not find it.  Any ideas where it was?

passenger side between the alternator and the distributor and below the dist level but above the oil pan gasket line, you can't miss it.

Thanks.  I remembered it was on that side, but I could not find it...  I'll look again this weekend.

if you can't find it then it's missing :lol: - might explain why is not working

He'd then be able to spot the location by the fountain of oil squirting out.

Oh, I found it...  now if I could only get it out!  Between the engine mount, ac compressor, engine block, and distributor, there is no way to get a wrench in there!  I tried a ratchet set (using the impact drill socket, as the are longer), and it would have worked, but the socjet topped out about an eigth of an inch too short (darn senser is just too long!).  Any ideas on how to get it out?

Hmm, I don't remember it ever being on that tight.  I think I ended up unscrewing the brass fitting with the sensor.

Oh, you can 'miss it'. If it's the same one as on my 2.5L '98 TJ, it doesn't look like any other oil pressure sending unit I've ever seen. It's also the most damned expensive one, too.

The brass fitting is not too tight; I could unscrew it by hand if the sensor was not in the way.  Problem is, with the sensor attached, it will not rotate 360°, so no dice there.

In this pic it does not look too tight, because I have the phone resting on the engine mount (IIRC).  But there is no way to get a wrench in there (not to mention that the only wrench I have that will fit the sensor is the adjustable one, which is not the smallest!).  But you can see the bottom of the compressor in the top of the picture.

use a combination wrench at an angle and another one to get leverage at the other end, that's how I changed mine.
or if you can spare one bend it (get it red hot) and would fit even better.
one of the articulated ratcheting wrenches would work best (although I have no idea if it fits in there.
another thing you can do is to cut a socket (just the hex part) and weld it to a pipe so you have enough inside reach to go over the body. 

as a more ghetto solution you could try and destroy the plastic part to make room for the socket but careful not to break the thread or the elbow in the block.

unfortunately, I do not have that size combo wrench...  I think it's time to go to the hardware store!

Hmm, did they move the sensor forward on the later YJ's?  I don't remember mine being that far forward.

always been in the same spot, i think they just added an elbow when the larger sender came with it so it point up rather than to the side.

Mine's on a elbow as well.  Just didn't think it was that far forward.  I haven't had any issues with mine adter I swapped it back in 2002, I think.  Was pretty easy to remove.

The elbow on mine wen bad while on a trip lost all oil pressure and had NO tools to work on it.  A plumber pulled over to se if he could help and we took everything out with a set of vice grips.  He had the correct size brass plug to plug where the elbow went.  Would not take a dime and told me to help someone down the road.  Was a pain in the posterior but it worked well enough to get me home.

If I don't go to the beach this weekend, I will try to pull this out once again.

Well, I am glad to report it is finally out.  Had to buy a new wrench to be able to get to it, but $10 later, it is FINALLY done.  Unfortunately, it will take my hands and arms a couple of weeks to recover from all the cuts and scrapes from the cut zip ties that I met along the way...  SO, officially as of today, the only thing on the Jeep not working as it should is the e-brake.  Now I have to find a way to reduce the length of the cable (I already maxed out the adjustment thingy under the Jeep) for them to really bite.  Any suggestions?

'They' used to make a little piece just for that. You could buy it at PepBoys or WallyWorld or most any local parts store. It was a little piece of metal rod that hung over the brake cable with a little hook with a nut on the end to draw the cable tight. Since I know what I'm looking for, I'll check a few places in the morning. If I find it, I'll post the store and part number.

Thanks Hunter!  I'll also try to find a local parts store with something like that...

Now, just to be clear, the Jeep already has something like this (http://shop.advanceautoparts.com/p/dorman-help-brake-cable-adjuster-universal-03006/5014557-P#); the problem is that over the years, the cable has lost tension, and now the tensioner is maxed out and the e-brake still has a hard time engaging.

EXACTAMUNDO!! That's the dingus. If you're really stretched out, you can use two or more.
I found them at NAPA. There's a guy on ebay that sells them for $3.97 a piece. $4.95 shipping for as many as you need.
You'll find if you look at the picture, when you go to put the dingus on, you'll want the nuts where the hook is and the hook where the nuts are.

adjust the brake shoes  but unscrew the e-brake cable adjustment first

OK, need a little more explanation here...  Sounds like you are on to something which I want to hear!

there's a spreader on the bottom between the brake shoes which you can adjust thru a hole on the back plate which is usually covered by a rubber plug. loosen the cable nut first to be able to adjust this spreader to max, then readjust the cable. easiest to understand if you take a wheel off and the brake drum

the other thing is to make sure your shoes are not worn out.

You get the E-brake recall.  Had mine done years ago.
