Do I have a flywheel notch for timing? no BB?

[FJB7340]

I installed the pertronix electronic ignitor II with the flamethrower II coil and I got everything installed. I turned the key and it fired up without too much hesitation.

I got my timing light out and went to time it but I can't find the BB that Im supposed to have on my fly wheel. All I can see is a notch. My timing light can be adjusted up to 60 degrees. I started at 0 and went all the way to 40 degrees before I saw a notch. I kept going all the way to 60 degrees and the notch was the only thing noticeable on the flywheel I could find.

My engine ran pretty well before the install. I drove it almost daily and I would think if my timing is supposedly this far off my engine would run at all. Why can't I see the bb?

Im seeing one of these 3 notches in my timing light set to 40 degrees advanced. Between 0 and 40 I can't see the BB.

It should look like this and I believe the BB is 7* degrees before top dead center.

OK. Thanks. I guess I need to retard it a bit by turning back the dizzy? Because I havent seen the BB or the TDC line by advancing it via the light.

You might want to remove the clutch inspection cover and clean the BB and the TDC marks, sometimes they are too dirty to see with the timing light, however, if the flywheel is OEM the timing marks should be there.

The BB and TDC is clearly visible at 6:30 on the flywheel.

Ah! It hadn't even crossed my mind to remove the cover and clean the bb and TDC mark. They very well could be too dirty to see as a PO removed the window cover and didn't put it back.

BB is 7*BTDC...

As Mike suggeted, I removed the inspection cover and slowly rotated the flywheel, until I found the TDC mark and the BB... then I cleaned and painted them with a fine white marker... makes it easy to see with a timing light.

You can rotate the flywheel, using a socket on the alternator pulley nut.

So I removed the inspection cover and there it was. It was pretty dirty so I cleaned it up and dotted it with a white marker. Thanks guys. She runs good now and I even got it up to 50mph for the first time and ran smooth! Now just a little fine tuning on the carb. and I think Ill be good to go.

It's funny how this post came up a day after I removed my clutch And flywheel and I had a few questions about the condition of things .then someone said to look by the timing Window in the Bell housing. I did not know that is were you time the engine from. I am constantly learning something new on this site.

The location wasn't exactly intuitive to me... I always found the timing mark on the crank pulley.

I was also told to mark the crank pulley when I got it timed but I couldn't really find a good stationary place to mark off of for reference. Where is yours marked?

Sorry, I wasn't clear... PRIOR to my FJ40, I always found the timing mark on the crank pulley.

The FJ40 has NO timing mark on the crank pulley...

I wouldn't bother marking the crank pulley... Just use the timing marks on the flywheel... The line is TDC... The BB is 7*BTDC.

A Paint Pen, Nail Polish, pain... all make finding the mark a lot easier. I painted the bearing and a circle around it to make it easier to find. Timing was so much easier afterwards.

I also would highly recommend reading the manual. I couldn't get my hands on a FSM back in 1991 when I bought my 40... and it wasn't in my budget. I did read the Haynes manual cover to cover more than once... Mud is also a huge asset, because even the best manuals don't explain all the parts that I've mixed and matched from different years, vehicles, and sources over the years. And, you'd have study the manual very closely to find all the "hidden" ground locations on a 40, or learn about all the things that can go wrong.
