Someone please tell me if this is NOT "zero." Otherwise, I think I've got the gist of it. The greenbook seems to have a typo- it says to lock the IP gear with 5193, then turn the back sprocket to set the pump! That seems rather impossible.

You are right dont bother with the locking pin. It seems misleading.

First bring engine to as accurate TDC as possible.
Set dial indicator gauge with about 2 turns preload. You want to be sure the IP bottoms out before the gauge does.

Gripping the just loosened rear cam shaft sprocket with a tool in the spokes, wind it backwards until the dial gauge reading goes to its minimum. This is the "zero" you want.

Set the rim marker and the dial to that zero position.

Now turn the cam shaft sprocket forwards till you get about .9mm or the position you have chosen. Tignten up the sprocket center bolt a bit, enough to make sure it wont move but don't torque it.

Now using the crankshaft bolt turn the engine backwards a bit. It should go back to that same zero mark on the dial indicator.

Now turn the engine forwards again till you reach TDC. Read the gauge. This is how far your timing is advanced.

Make fine adjustments till you get the figure you want. You will find that you have to go a teeny bit higher than the value you want for it to come right.

Once you are happy with the position, torque up the rear bolt. I do this by reacting against the already tightened front camshaft bolt with a wrench but others prefer other ways.

Its quick and easy once you have grasped it.

Good luck,
