Ford 4400 timing

Getting ready to pull the distributor to retime the motor, in the book it says that there s a arrow in the rectangular inspection opening, but I don t see it. Do you just line up "0" (I guess "0" is top dead center) in the middle of the opening then adjust the distributor? The tractor has electronic ignition and the vacuum advanced is still attached.

Flywheel should be stamped 0-2-4-6-8-10----20----30.

The arrow is on the plate, not the flywheel.

(quoted from post at 17:35:12 06/17/19) The arrow is on the plate, not the flywheel.

Thanks, I'll wipe of more grime off that plate. When we got the tractor, the tractor was missing the cover for that.

Ended up not finding the mark on the plate.

I just checked a 5000 - no mark. I then checked a 7710 and the mark was there. The arrow simply shows the center of the opening.

Thanks, I was planning on getting "0" as close to he center as possible.

Depending on the year, pre 68 times at 4 degrees BTDC
post 68 times at 2 degrees BTDC

So it s 2 for tdc? I wonder why the book has tdc at 0?

Bern · Jun 18, 2019

TDC is zero. 2 degrees is 2 degrees.

Do you know what TDC means? It means Top Dead Center. The degree scale is referenced and begun at this
point.

Yes I do know what TDC means. I was wondering what BTDC means?

BTDC = BEFORE Top Dead Center. So, any number other than zero would be BTDC. You'll notice that the numbers
on the flywheel are only on one side of the zero, which just happens to be the leading side as you rotate
the engine in the normal direction of rotation. All gas and diesel timing events are done BTDC. None of them
are done ATDC.
