Installing your new Dizzy, Plan A
- FOLLOW THE DIRECTIONS THAT COME WITH YOUR DUI. These have already been posted in this thread previously.
- I ended up using only the thin shim that came with the unit to help seal the connection from the shaft flange and keep the oil from coming out. I didn't have any bottom-out issues.
- Remember that photo that you took of your old dizzy when you took the cap off? Now is the time to study that real hard and work to put your new dizzy in the same way. I DID NOT do this and had to resort to plan B (see below).
- If you did take this photo, have verified that your dizzy shaft is NOT bottoming out, and you're ready to roll...
- Turn the dizzy "pointer" 30 degrees clockwise to where it was in the photo. This means that if the dizzy pointer was pointing directly at the passenger side headlight when you pulled it out, you would rotate it to point at the driver's side headlight (roughly). This will allow the dizzy to engage with the teeth on the way down, turn 30 degrees counterclockwise (from the driver's side headlight back to the passenger side headlight) and settle right into place just like your photo.
**DISCLAIMER. Even if you took the photo (which, again, I did not), I think my Plan B of finding Top Dead Center is a better option.
PLAN B
- Because I didn't have any idea where my old dizzy's "pointer" was pointing, I had to start from scratch which was to find Top Dead Center (TDC) on Piston #1 and work my way from there.
- To find TDC (the point where your #1 piston is a the highest point of its stroke), I had to:
- Pull the #1 spark plug
- Rotate the motor manually to manipulate the pistons so that piston #1 is a the top of it's stroke using the huge bolt on the bottom/front of your motor where your belts attach to or use a long screwdriver to do the same.
- Also keep an eye on your flywheel for the BB or a line etched on it. In my case I had a BB AND a line that were 180degrees off from one another. I mistakenly thought that I had TDC when I lined up the etched line and I was actually 180 degrees off and had to find the BB instead.
- A helpful tip here was to plug the opening of the #1 sparkplug with my thumb while someone rotate the motor. I could feel the air pushing against my thumb indicating that the piston was on the way up. When the BB showed up on the flywheel, I knew I found TDC.
- Now that you've found TDC, it's time to drop your dizzy in. The
attached instructions saved my life. Follow them step by step.
- Word to the wise: you'll need to use a long screwdriver to make sure that your oil pump slot (at the very bottom of the opening in your motor where the dizzy shaft goes) will line up with the dizzy shaft. This might take you a few tries to get right.
- Aim the dizzy "pointer" 30 degrees clockwise (almost at the #3 spark plug). This will allow the dizzy to engage with the teeth on the way down, turn 30 degrees counterclockwise and settle right into place pointing just to the right of the #4 spark plug (see the attached PDF for photos of how this should look).
- Finger tighten the dizzy clamp bolt (you'll need to turn the dizzy for timing so don't crank it down).
- Once you're here, you're almost home.
Install Dizzy Cap, Hook Up Spark Plug WIres, Hook-Up Power
- The DUI dizzy cap does NOT have numbers on it which I thought was a factory mistake. Turns out they know exactly what they're doing and I had no clue what I was doing (shocker).
- With your dizzy "pointer" aimed just to the right of the #4 spark plug and your #1 piston at TDC, when you put your dizzy cap on, the pointer should be VERY close if not directly pointing right at a connection for a spark plug wire on the cap.
Congrats! You've just found where your #1 spark plug wire connects.
- Go ahead and connect the remaining spark plug wires in the correct firing order going CLOCKWISE. In my case, I'm running a 2F which has a firing order of 1-5-3-6-2-4. A great way to remember this is the saying "15 is too young, 36 is too old, 24 is in the middle..."
- Go ahead and hook up the 3-pin connector from the bottom of the dizzy to the cover just like it came in the box.
- Then connect the 12ga wire from terminal #87 off of your relay into the "BATT" connector on the dizzy.
- Your motor should fire right up.
If motor doesn't fire
- You may be 180 degrees off from TDC like I was. If your motor isn't firing, find TDC again using the same steps as above and pull your dizzy cover. If it's pointing exactly opposite of the #4 spark plug, you have joined my 180 club and will have to pull your dizzy and re-install.
- If you are right where you need to be and it still won't fire...I'm no more help to you. Sorry
If motor fires, let's get to Timing
- I reached out for help locally to borrow a timing light from a Rising Sun 4x4 club member here in Denver because I didn't want to purchase one.
- With the motor running, we hooked up the adjustable timing light and pointed it at the flywheel with a setting of 0.
- Very gently, I turned the distributor until the BB was hitting the indicator line perfectly. This meant that we were at 7degrees which is the factory setting.
- We then adjusted the timing light to 6 degrees to get to our advanced timing of 13 degrees. Once the BB was landing on the indicator line, I clamped the dizzy clamp bolt down tight and we were done.
Here is one last photo of the finished product that I hope is helpful.
And one more photo highlighting where I ran the heater hose below the dizzy.
Hope this helps someone in the future.
