Setting 0* top dead center December 20, 2010 12:13AM
Where is TDC the pitons is there for a couple of degrees it 0* when the pitons is there? When the piston starts to leave? when the pistons is doing nothing. application for setting timing tape and pin on a fluid dampener

TDC= top dead center. Dead=no movement. Center=the middle of no movement.
Record when piston stops coming up, and starts down. Split the differance for TDC.

a degree wheel,dial indicater,piston stop are used to find this.there is a area where the crank will move slightly and the piston will not.there are many variables to that area.mine is 4 degrees.

With degree wheel on crankshaft, rotate engine until piston contacts piston stop. Note degree wheel reading. Rotate engine the opposite direction until piston again contacts stop. Note degree wheel reading. Halfway between the two readings is exact TDC.

are all timeing tapes the same distance apart?

no, you will need to buy timing tape according to the diameter of your dampner.

See if this helps. What works on an M in this example for the most part goes for any other engine.

Timing tape graduation is specific to dampener diameter. The larger diameter dampener, the farther apart the graduations become. If a tape is not available, the dampener/flywheel can be marked in the following manner. Diameter x pi = circumference. Circumference divided by 360 = increment between degree marks. You can also mark the dampener using the degree wheel. From TDC, rotate the crank in 1 degree increments and make a corresponding mark on the dampener at each degree.
