How is the position of the exhaust balance shaft of the overlord 2 7 correct?

How to be right: Have timing marks, and make marks with yourself. Why:

Knowing the camshaft, the camshaft turns up and pushes the valve. The car needs to be balanced, and the generator can't shake, so when moving, one is up, and the one is symmetrical under the cylinder, based on this idea, this is one of them, and the second is that the piston movement of the generator is separate from our valve movement, but our engine piston must be ready to inhale, or exhaust, how to make them a whole, it needs to be timed. The result is to inhale at the right time, open the intake valve, open the exhaust valve at the right time, exhaust.

Newbies just need to remember the timing mark. It doesn't have to be complicated.

If the engine valve mechanism, crank connecting rod mechanism, and intake and exhaust system are not aligned, the engine can not be properly coordinated to make the engine work. Timing belt: Timing belt is an important part of the engine valve system, which ensures the accuracy of intake and exhaust time through the connection with the crankshaft and a certain transmission ratio.

The belt is used instead of gears because the belt is quiet, has little variation and is easy to compensate. Obviously, the life of the belt is definitely shorter than that of metal gears, so it is necessary to replace the belt regularly.

The timing chain has three colored plates, marked on the balance shaft on both sides and the crankshaft in the middle.

The installation method of the balance shaft is as follows;

1) There are 3 tinted links on the timing chain, 2 of which are chrome-plated silver-gray and 1 is copper-plated brownish-yellow. Align the timing markings on the intake side balancer sprocket with the copper-plated links.

2) Turn the timing chain clockwise, align the chrome links with the timing marks on the balance shaft drive sprockets on the crankshaft, and the chrome plated links are at about 6 o'clock after alignment.

3) Place the timing chain on the water pump drive sprocket. Targeting doesn't need to be very strict here.

4) Adjust the last chrome link so that the timing markings on the exhaust side balancer shaft drive sprocket line up with it.

5) Install the balance shaft timing chain guide plate and bolts, and the bolt tightening torque is 15N·m. Install the balance shaft timing chain small guide plate and bolts, and the bolt tightening torque is 15N·m. Adjustable guide plate and bolt of the timing chain of the balance shaft are installed, and the bolt tightening torque is 10 N·m.

6) Turn the balancer shaft timing chain hydraulic tensioner plunger 90° in its hole and press the plunger, turn the tensioner back to the original 12 o'clock position, and insert 1 paper clip through the hole of the plunger body and insert it into the plunger of the tensioner.

7) Install the balance shaft timing chain tensioner and bolts, the bolt tightening torque is 10N·m, and remove the paper clip from the balance shaft timing chain tensioner.

Note: If there is no timing between the balancer shaft and the engine, the engine may vibrate abnormally or make noise.

Balancer shaft technology is a simple and very practical engine technology, which can effectively reduce the vibration of the whole vehicle and improve the driving comfort.

Working principle] In the working cycle of the engine, the piston moves very fast, and the speed is very uneven. At the top and bottom dead center position, the speed of the piston is zero, while the speed reaches its highest in the middle of the top dead center. Due to the repeated high-speed linear motion of the piston in the cylinder, a large inertia force must be generated on the piston, piston pin and connecting rod.

The old Toyota domineering four-cylinder engine displacement timing chain is right.

Install according to the mark, and press the right side tightly on the left side.

Don't touch the engine timing cover and timing.

Point-to-point.

3.Balance the convex place of the shaft down (the convex place you should know to put in the middle of the shaft like axis C yes it is not clear how to say exactly).

4.It's OK to install it, if it's wrong, the engine is shaking, haha, it's very shaking, it's abrupt.

Highlander balance shaft and crankshaft mark need to be matched with camshaft mark, the specific operation steps are as follows:

1. Pair the Highlander balance shaft mark.

2. Pair the Highlander camshaft mark.

3. Pair the camshaft mark on the other side.

4. The balance shaft mark on the other side.

5. Finally, the timing mark of the upper crankshaft is completed.

The center of gravity is downward. Top dead center of the first cylinder of the crankshaft.

The top dead center is not OK.

For the parallel position of the four pistons, first turn the crankshaft to the top dead center and then turn 90 degrees clockwise, align the small dots on the top of the signal disc with the seam of the large tile cover and the cylinder block, and then put the balance shaft mark on it directly (the two shafts of the balance shaft have dots and the marks on the top of the shell are aligned, and the two points must be aligned with the marks).

No thanks, everyone shared.
