If you look at the roll pin on the aftermarket distributors, on one side of the gear the pin hole is directly above a gear tooth. If you look at the other side of the gear you will see the pin hole is between the gear teeth. Rotating the gear 180 degrees corrects the phasing of the shaft and allows everything to line up. Apparently it is a crap shoot when you buy an aftermarket distributor as to which way the gear is installed.
Distributed shaft slip on a points distributor will cause large points gap differences at different rpm’s I was 550 miles away when it happened to me drove it home on the sweet spot which was 50 mph before I figured it out it was a long day
Dex I just want to say this because I recently worked in a factory making capacitors but every thing I mean everything is out sourced theses days nothing is 100% made in house anymore and my factory had military contractors and made medical equipment sometimes all that to say all your paying for with more expensive items is quality control are parts where made right here in America that was are stick but what it really means is it’s assembly in America with American standards of quality control and it’s been this way since the 80’s at least all this to say the cheap and expensive parts share a lot of the same parts and what makes one more expensive and better is that quality control and making sure the more expensive items are actually to spec not just assembled
I could be wrong but the original Jeep distributor shaft is drilled offset and you can’t get that drive gear 180 out.bloody good job 👍🏻 on the video. I went through this several years ago and you sharing the information is very helpful and good of you.
I had an issue with a Spectre distributor for a small block Ford. It was too tall, and caused a bind when I clamped it down. Luckily I shut it off before things went south.... but it violently spun the distributor around. Soooo, I also found a used distributor, and we're golden.
ALSO make sure that the lower bushing oil return back to motor are drilled or grooved before they have bushed the bushing in. I had one leaking engine oil from new and I drilled along side the bushing and housing
I tried the gear 180 reversal and it worked for a few miles then started missing and pretty sure cel also. I had to take good parts from the new one and use my old shaft so the pickup would match.
Hey dex. Quick question got a 01 xj 4.0. I swamped it. Anyway I got it all cleaned up and cleaned out. But even with starting fluid I can’t seem to get this thing to start. Love all the videos brother! Any tips would help!
Did the same thing to the Chinese distributor I put in about 20k miles ago. The original one was so bad it was making a chirping sound and loosing cam signal!
My cj5 has a xj motor and I'm just about to change the timing chain, and harmonic balancer, I had 2 exhaust explosions that we're like bombs, thats an indicator of a retarded timing system, but everything except the block is new. So. I was wondering about the distributor that is also new, the things you just showed are exactly what I've seen , but I dident understand why, now you just hit the nail on the head , I was getting it ready today, tomarow everything will change, and I'll be shure to let you know if my jeep still does 4.0 wheelies 😅 oh yeah. Dex 👍
Hey Dex, is there a way to message you and get in contact or is it by phone call only? I have a 97 XJ that was built in February of 97. It has manual windows and locks. I've been searching years trying to find 2 good replacement front door panels because mine doesn't have the foam arm rests. My Jeep didn't have them when I,bout it 5 years ago and it's always drove me insane because I wanted to fix it. I'd like to be able and send you a picture of my panels for color comparison. I think it's Ash Gray possibly?? I live in East TN and wish I was closer to be able to just stop by your shop with my Jeep and see if you had any good front panels for sale. I can send you a picture, but I don't have the contact information to do so. Thanks and Take Care! Jon
If you look at the gear, the roll pin hole is in a valley on one side and a ridge on the other. So, basically it’s either right on or a half tooth off depending on it being installed correctly or incorrectly. I put a new distributor in my Jeep and it started throwing misfire codes for every cylinder. I pretty much started pulling my hair out. But consulted the forum people and one of them said it may come from the store installed wrong. And it was.
Yeah, the roll pin hole lands between gear teeth on one side and in the middle of a tooth on the other side. Actually, most distributors I've disassembled are this way and in some cases it matters. The reason I've had to replace the gear most of the time is because the cam might be billet or cast iron and the gear material isn't compatible, thus needs to be changed.
Hey Dex I really like this video what you're doing, however do you know, are you aware, that you're only showing one type of distributor which doesn't fit in my 4.0? Apparently you chose the late model engines to do this video on, because my 1988 4.0 has no distributor like what you're showing. It has those things that you cut off, but whatever that little black plastic pieces that you put inside the distributor with the wires hanging off of it, mine doesn't have any of that, my wires go in through the bottom of the distributor, are you aware of this? Okay it doesn't actually matter too much if you just do whatever, so I just want to say this for all those out there that might have the same motor without that very distributor that you're trying to show. Because there are two types of Distributors obviously at this point, and they do not have the same features at all. Even though there's a still the same distributor. Okay peace
You're supposed to stick something in those alignment holes to keep the rotor from moving as you drop the distributor in. The aftermarket distributors should come with something to lock the 4.0 or 2.5 position in, and it's even recommended to cut one of the ears of the tab off, nothing new. This new caveman fad about rotating the distributor gear is ridiculous lol. RUclips is doing it all wrong, I never seen so many missing steps 😬.
I love how you are willing to try about anything and share it. 😊😊😊😊😊

aftermarket workers smoking that gas on break time putting the gears on backwards!!! great quality control
lol you better know it
Dex, I drive a 93 yj Renegade and basically just keep it on the highway but man I love your channel and hope you stick around a long time

No shut. Let me guess larger caps that's been a thing. Even fords and Chevy's are made in China then assembled here. How is that possibly cheaper?
I've found white box parts are often better quality than reboxed name brand.
This helped me to much it was backing firing at 1500 rpm and replaced everthing couldn’t figure it out don’t this works perfect now thanks so much

Back pocket knowledge is priceless!
I have worked on my jeeps with 4.0 l for many years and never known that ! Thanks for showing in a video !!
7:56? Past ur bed time?? 😂🤙 The more you know with DeX💫
YOU ARE ONE AWESOME FRIEND THANK YOU FOR GIVING US THIS INFO.
Bro !! Hell yeah man, I needed this video so bad
First.
Also have been waiting for this video, I remember the original video and comment you referenced.
Thanks, Dex
Dex , there's nothing your doing that's not worth it. You do a fine job,
I'm pating you on the back for good measure. Peace.
Love it. I can do that to mine sitting in the corner... because it gave me a check engine light.

All one has to do is drive out roll pin rotate gear 180 right, that's awesome, Dex. You the man good advice thanks fella
You bet
@@dexjs question. What would it take to swap out a 2.5L 4cyl, with a 4.0L 6cyl?
Other than the engine, transmission, mounts, exhaust...?
Thanks😎☕
Awesome information thanks for the time and effort to help us out.
Great info! Scene at the end is hilarious 😂
Another very useful video! 👍🏻👍🏻
I appreciate the videos you make!

Knowledge is power.
Thanks DEX.JEEPS.
Lmao the thumbnail outro
Worth noting for renix jeeps removal of that alignment tab to adjust timing is an official tsb
Good stuff, thanks 👍

great job thanks for sharing
Great video!
Thanks!
look at the keyway on the Hal balancer compare to TDC
Thanks dex
Good stuff. ❤❤❤😊
You are awesome ❤️
Did the same thing to the Chinese distributor I put in about 20k miles ago. The original one was so bad it was making a chirping sound and loosing cam signal!
Nice fix🎯😎☕
Recently purchased a Yj any recommendations on a junk yard 4.0 motor. I’m not looking to rebuild it. I just want to get the Jeep up and running.
My cj5 has a xj motor and I'm just about to change the timing chain, and harmonic balancer, I had 2 exhaust explosions that we're like bombs, thats an indicator of a retarded timing system, but everything except the block is new.

Nice! 😊
Hey dex do you have any 4.0 equipped vehicles with true duels? Like REAL duel pipes three cylinders per pipe
Now I know, and knowing is half the battle🇺🇲
G I Joe! Lol
Dos that need ecm for distribution i know you need ecm for gas but

Wait...? They Said rotate the gear driving the dist. 180° rather than the housing... The symmetrical gear? Genuinely curious

So, basically it’s either right on or a half tooth off depending on it being installed correctly or incorrectly. I put a new distributor in my Jeep and it started throwing misfire codes for every cylinder. I pretty much started pulling my hair out.

What about a 1993 4.0
I bought one from O’Reilly’s it was off turned the gear 180 went right in.
I’m removed the gear and turned it 180
Maybe I should rebuild my old one?
👍🏻👍🏻👍🏻🇦🇺
You can take it one step further and re-use the original gear. It's a much better alloy than the soft aluminum gears from china. Do your cam a favor!
FIND NOS problem over 😀

This is the only one I’m aware of that China makes like this with this issue. Just going off things I hear and see.
All I can say is MAGA 👍🏻🇦🇺start making all things back in the USA 🇺🇸 problem over 😀.

A tire stem valve remover drops in perfectly.
