This is not a forum for automotive data. But "tappet clearance" is a UK term, only. Try search for "valve clearance" and "Hilux 2400 cc" or Hilux 2400cc"

Hey there I need the exhaust and Intake(valve) clearance for a komatsu 300-6 please


note Perform the valve clearance check and adjustment at the engine cold state. 1.Remove all of the ignition coils. 2.Remove the cylinder head cover.
caution Turn the crankshaft always clockwise. 3.Turn the crankshaft clockwise, and align the timing mark on the exhaust camshaft sprocket against the upper face of the cylinder head as shown in Figure. Therefore, No.1 cylinder goes to the compression top dead center. 4.Using a thickness gauge, measure the valve clearance with the arrow shown in Figure. If deviated from the standard value, make note for the valve clearance.
Standard value:

    Intake valve 0.20 ± 0.03 mm (0.008 ± 0.0012 inch)
    Exhaust valve 0.30 ± 0.03 mm (0.012 ± 0.0012 inch)
5.Turn the crankshaft clockwise 360 degrees, and put the timing mark on the exhaust camshaft sprocket in position shown in Figure. Therefore, No. 4 cylinder goes to the compression top dead center. 6.Check the valve clearance with the arrow shown in Figure. In the same procedure as 4.
7.If the valve clearance is deviated from the standard value, remove the camshaft and the valve tappet. For the camshaft removal, refer to Camshaft Removal and Installation . 8.Using a micrometer, measure the thickness of the removed valve tappet. 9.Calculate the thickness of the newly installed valve tappet through the following equation.
A: thickness of newly installed valve tappet
B: thickness of removed valve tappet
C: measured valve clearance
Equation

    Intake valve: A = B + [C - 0.20 mm (0.008 inch)]
    Exhaust valve: A = B + [C - 0.30 mm (0.012 inch)] note The valve tappet ranges 3,000 - 3,690 mm (0.1181 - 0.1453 inch) and has 47 types per 0.015 mm (0.0006 inch). The thickness below a decimal point is stamped on the reverse side of the valve tappet. 10.Install the valve tappet selected through the procedure 9, and put the camshaft in position. For the camshaft installation, refer to Camshaft Removal and Installation .
    11.After installing the timing chain, measure the valve clearance using the procedure 3 to 6. Confirm the clearance is within the standard value.
    caution Completely remove all the old FIPG, which might be remaining among the components. 12.After completely removing the liquid gasket adhering on the timing chain case, cylinder block and cylinder head, degrease them with white gasoline.
    caution The cylinder head cover should be installed within 3 minutes of applying liquid gasket.
13.Apply a 4 mm bead of liquid gasket as illustrated.
Specified sealant:
    THREE BOND 1217G or equivalent
14. Install the cylinder head cover and tighten the tightening bolts using the following procedures.
(1) Temporarily tighten to the following torque in order shown in the illustration.
Tightening torque: 3.0 ± 1.0 N·m (27 ± 8 in-lb)(2) Tighten to the specified torque in order shown in the illustration.
Specified torque: 5.5 ± 0.5 N·m (49 ± 4 in-lb)15.Install the ignition coils.

After my mower gets hot it makes a ticking noise


It really depends on where the "ticking" is coming from. Was the ticking there before the leak was fixed?
If it is an 04 model, it is 10 yrs old. How many hours? Try to determine if it is coming from the area by the valve covers. You may have a tappet clearance issue. Check the clearance between the tappet and valves, check both sides (Twin 18 hp?). If any are out that is where the ticking is coming from. Could also be a worn cam, but sounds like a valve tappet problem.

Valve Clearance


Modern cars are hydraulically adjusted at the tappets so there is no adjustment. However the pivot points for the rockers can become seriously worn giving the same noise. The hydraulic tappets them selves wear and allow the oil pressure to drain off too quickly meaning there is a clearance every time the cam activates the tappet. I would have a leak down test done on the hydraulic tappet units and check the rocker shafts for excessive wear.

How can i make a tappet clearance of honda vtec 98


You will need a "tappet gauge/blade" and then here is what you have to do:
1. open engine head, its the cover of engine where HONDA is written.
2. Now jack up and one side of the car and put the car in 4th gear
3. Start from any one side, if the tappet is not in "UP" position then rotate the wheel (the jacked up side of car) and once the tappet moves up, stop there.
4. Loosen the nut of the tappet and put the tappet blade in between the tappet gap. Now using screw driver, tighten the tappet so that blade fits snugly between the gap and without moving anything (blade and screw driver) ask a helper to tighten the tappet nut finally.
5. Repeat above procedure for each tappet.

If you do it carefully, there will be no tappet sound at all.

Top End noice


Not a lot of information but I assume you're asking about some noise in the top end of your engine on your Heritage.

A Harley-Davidson engine is of an older design being that the valves are pushrod operated. It is not an overhead cam design like a lot of other bikes that try to look like Harleys. Harley has decided to stick with this design for as long as they can because it lends itself to what most Harley riders are looking for in their bikes, the traditional look lines and sound of the older motorcycles.

As such, there are a lot of components in the top end that must have some "running clearance" in order to operate. Push rods, rocker arms, rocker arm bushings, and such. A slight clatter or tapping noise in not uncommon. Now, it the noise if loud enough to make people turn their heads when you start the bike, you may have a problem. Usually a serious problem in the top end of the engine results in a poorly running engine as well.

You engine is equipped with hydraulic tappets. As the engine runs and things start to expand, the tappets are "pumped up" with oil to maintain a "zero clearance" in the valve train. If you have a tappet gone bad, it will make a loud erratic tapping noise that is sometimes accompanied by a bad running engine. You could have lost a roller on the end of a tappet as well. The Twin Cam engine was designed to help remedy the problem with the valve train geometry in the Evolution and earlier engines. It did straighten the pushrods up a bit but I still think it's possible to lose a tappet roller. If the noise is this loud, you will have to pull the tappet blocks and inspect the tappets to see if you have lost a roller.

Good Luck
Steve

How to measure tappet clearance with dial gauge


When setting tappets, it has to be born inind that the valve stem wears an indentation into the face of the rocker. This prevents a really accurate tappet adjustment, so the customer is right again. If you do not posess a tappet setting dial gauge, a normal engineers dial gauge will do just as well. The procedure is the same as using your feeler gauge except that you set the dial gauge up on the cylinder head with the pointer resting on the head of the rocker. Press down fairly firmly on the rocker valve end and zero the gauge. Next lift up on the rocker and read off the clearance, from the gauge, Use a magnetic base to support your gauge and repeat the pocedure for each valve pair.
