Find Top Dead Center
(TDC)
First find the T on the right side of the crankshaft then you can see the marks on the camshafts
if you can't see the marks on the camshafts turn the crank one more lap
Now you have to find the exact TDC, to get the beast result.
You need a dial indicator that you put in the sparkplug hole at cylinder 1 or 4.
Then you need a degree wheel, mount it on the left side of the crankshaft.
Make an arrow that points to 0 (TDC) on the degree wheel. Then set the dial indicator to 0
Turn the engine forward until the dial indicator reads 0.1 mm, note the degree on the degree wheel.
Then turn the engine backwards until the dial indicator reads 0.1 mm again, note the degree on the degree wheel.
In the middle of this tow degrees you will have the exact TDC.
Turn the engine forward to the degree that's was in the middle.
If you have another degree than 0 (TDC) adjust the arrow to 0 (TDC)
Now you have the exact Top dead center (TDC)
