Here is a pic of it...You have to have it to replace the crank sensor on the newer Foeds...Jim
Yes, there's a special tool that is inserted into the crankshaft during this procedure. See http://www.etoolcart.com/browseproducts/Ford-Cam-Positioning-Crankshaft-TDC-Timing-Pin.HTML If he forgot to remove the tool before he started the engine, it will do damage to the crankshaft.
DOHC ENGINESee Figures 13 through 21A camshaft alignment timing tool (No. T94P-6256-CH or equivalent) and a crankshaft Top Dead Center (TDC) timing peg tool (No. T97P-6000-A or equivalent) are required for this procedure.Make sure the correct notch in the pulley is indexed to the lower cylinder block. Refer to the accompanying illustration.Fig. Fig. 13: A camshaft alignment timing tool ...Fig. Fig. 14: ... and a crankshaft TDC timing peg tool are required when removing and installing the timing beltRemove the spark plugs.Rotate the crankshaft to TDC.Locate and remove the plug bolt by the Crankshaft Position (CKP) sensor (refer to the illustration) and install the TDC timing peg.Fig. Fig. 15: Remove the plug bolt by the Crankshaft Position (CKP) sensor and install the TDC timing pegRaise the car and support it with safety stands.Unfasten the splash shields bolts and remove the shield.Lower the car and remove the water pump pulley.Remove the valve cover and the timing belt covers.Align the camshafts and install the camshaft alignment tool on the back of the camshafts as illustrated.Fig. Fig. 16: Align the camshafts and install the alignment toolWARNINGIf the camshaft belt is being reused, mark the direction of the camshaft belt to the rotation of the camshaft prior to removal, or premature wear and belt failure could occur.Loosen the tensioner pulley bolt and relieve the tension on the belt by disconnecting the tensioner tab from the timing cover back plate.Slide the belt off the sprockets.Inspect the belt for wear and replace as necessary.Fig. Fig. 17: Timing belt routing-2.0L DOHC engineTo install:If, for any reason, the engine was disturbed, the camshafts moved or the sprockets replaced, perform the following procedure:Make sure the correct notch in the pulley is indexed to the lower cylinder block.Position the crankshaft just prior to Top Dead Center (TDC).If not already done, locate and remove the plug bolt by the Crankshaft Position (CKP) sensor (refer to the illustration) and install the TDC timing peg.Rotate the crankshaft clockwise against the TDC peg.Installation of the alignment tool into the exhaust camshaft may require the camshafts to be rotated clockwise.Install the camshaft alignment tool on the back of the camshafts.Install the timing belt and engage the timing belt tensioner tab into the upper timing cover backplate.A3/8inch drive, 10mm, 2 inch torque adapter offset is required to tighten the tensioner bolt.Using a 6mm Allen wrench, adjust the tensioner until the index marks are aligned and tighten the bolt to 17-20 ft. lbs. (22-28 Nm).Rotate the crankshaft clockwise against the TDC alignment peg, then remove the camshaft alignment tool.Remove the TDC peg tool and install the plug bolt.Install the timing and valve covers.Install the water pump pulley and the splash shield.Install the spark plugs.If the engine or the camshaft were not disturbed in any way, or the sprockets were not removed, perform the following procedure:Install the timing belt and engage the timing belt tensioner tab into the upper timing cover backplate.Fig. Fig. 18: Engage the timing belt tensioner tab into the upper timing cover backplate ...Fig. Fig. 19: ... then use a 6mm Allen wrench to adjust the tensioner until the index marks are alignedFig. Fig. 20: A 3/8 inch drive, 10mm, 2 inch torque adapter offset is required to tighten the tensioner bolt (arrow)-2.0L DOHC engineA3/8inch drive, 10mm, 2 inch torque adapter offset is required to tighten the tensioner bolt.Using a 6mm Allen wrench, adjust the tensioner until the index marks are aligned and tighten the bolt to 17-20 ft. lbs.

The top dead center (TDC) on a John Deere 6420 can be found using a timing tool or by aligning the timing marks on the crankshaft pulley and camshaft. Make sure the engine is at operating temperature and turned off before attempting to locate TDC. Follow the manufacturer's instructions for your specific model to ensure accuracy.
The crankshaft pulley should have only one timing mark, and that is the one for TDC There are 5 markings. Looking from the front of the motor the marks start at right 15btdc, 10btdc, 5btdc, TDC, 5atdc. Top dead center will be the second marking from left then.
I really need to know how to tell if i have a loose crankshaft or crankshaft position sensor. Or could it be the timing belt . We just put in a new water pump but the timing belt was on TDC when we were done. PLEASE HELP !!!! Its running pretty crappy...
timing is set on a ZX2 by finding top dead center (TDC) on cylinder number 1 and aligning the cams. Once this is done, properly set the tensioner. TDC can be located by using a crankshaft locking tool. the cams can be aligned by inserting a flat piece of steel into the slot on the ends of the cams opposite the end with the cam gears.
Timing marks determine if the car is set on TDC(Top Dead Center). Just to make sure it is in time use a Timing Light. The timing marks are located on the sprocket under the valve cover and on the crankshaft. Timing marks determine if the car is set on TDC(Top Dead Center).

You have to set your camshaft at a position of firing at number piston ,that is if the camshaft gear does not have a visible timing marks and in relationship with the crankshaft position it has to be position number one piston at TDC
In K9K engine series: If you mean the tdc in order to lock crankshaft to replace timing belt, in front of the engine near the flywheel zone right below the oil pressure valve there is a small bolt (usually with a torx head "star"). Removing that bolt and inserting a special locking tool through that hole ,will lock crankshaft right on the tdc. No he means the TDC Sensor which is on top of the bell housing it is held in place on a banana shaped plate which is bolted to the engine with 2 10mm bolts.
u need a special tool which holds camshafts in timing and crank needs to be 30 degrees after tdc.
When the engine is at #1 TDC, the dot on the crankshaft sprocket is at 12 o'clock, and the dot on the cam sprocket is at 6 o'clock.
You can find it on the crankshaft pulley and there is a hole in the camshaft pulley which must be line up with the mark on the cylinder head at TDC.
