I need help with my IP.

I need help with my IP.
I need help with 2 things. First off, I removed it just like I was told not to.
I have the whole timing gear for it off and I don't know how to time it.
My book says I should have marked it first.
The other thing is the govener is messed up. Before I pulled the motor I over revved it twice.

Not sure if this helps:
(I know the text telling you to draw a line won't, but if there are windows/holes in the gear as the image shows maybe??) Looks like there should be a hole or dot at the top of the gear that should line up through the center of the gear through the center of the cam gear and the center of the crank....
1984---87
1. Perform steps 1 through 4 as described for 1983 models.
2. Using suitable tool, remove plugs, then turn engine over by hand to TDC of compression stroke of No. 1 piston. To determine that No. 1 piston is at TDC of compression stroke, position injection pump drive gear dowel at four o'clock position. The scribe line in vibration damper should be at TDC.
3. Draw a line on front of injection pump drive gear at six o'clock position where the one locating chamfer meshes between the two chamfers on the camshaft gear.
4. Remove injection pump drive gear.
5. Reverse procedure to install, noting the following:
1. With drawn line on injection pump drive gear at six o'clock position, install gear and align all drive gear timing marks, Fig. 11. Use extreme care to avoid disturbing injection pump drive gear after it is set in position.

If you didn't mark it, I believe seeing the timing marks without pulling the front of the motor off is next to impossible.
I remember something about a shiny butter knife being used to see the mark on the cam gear.
IIRC ... Rotate the cam gear mark to the top, then set the IP gear aligning the marks, install cover, install IP.
There is a whole thread on this issue around here someplace with really good info, to bad it isn't in a sticky.
I lost all my links, thus have lost all that good info I had bookmarked!
-Enjoy

There is a dot on the crank gear.
The cam gear has a dot that goes next to the crank gear dot.
When those two are beside each other, there will be a y on top of the cam gear.
The IP drive gear also has a y on it.
When the engine is in time, all four marks make a straight line from top to bottom right thru the center of each gear.
And at that time, the timing mark on the harmonic balancer should be right on the TDC mark on the timing gear cover when you install it.

I actually removed my gear recently because I had to repair the aluminum cover. I don't have a dental mirror, but I do have a mechanic's mirror with a nice telescopic stem and the mirror is thin enough to fit between the front engine cover and the camshaft gear to read the timing mark. I realigned everything without having to pull the water pump or front engine cover. No more oil leak either.
Wish I found this thread sooner because you can indeed find that timing mark without having to open up the front of the engine. Its still is much easier to leave the gears there and remove the pump and lines separately, but its not the end of the world if you remove the timing cover as long as you have a thin mirror like that handy.

Thats what I get for putting to much faith in Haynes.

Thanks to all of you guys.
I can't wait to have this running!

I have read Haynes and Chiltons both.
Both books have good points and bad points.
Either is better than none.
That said, when I am working on my engine I am not after the how to, but I still use a Haynes manual to double check myself on torque values and patterns.
You could use a Chiltons manual for the same thing.
This forum may take a bit longer than reading either of the above to get your answer, but at least after you get a couple replies you will have the best info you can get.
I don't remember which book it is, but it actaully tells you to loosen the lines at the injectors, unhook the throttle cable and fuel supply and electrical connections, then remove the four bolts holding the IP drive gear cover down and removing everything as one unit.
Want a better book, find a Helm's, but it is not going to be cheap.
I see them on E Bay for around 100 dollars every so often.
