Snug down the rocker just until you begin to feel resistance. 7. #1 is now on compression stroke (both valves closed/ rockers loose) while #6 cylinder is on the exhaust stroke.Repeat With The Next Cylinder In The Firing OrderThe next cylinder in the firing order is #5. Shaft style rockers are best (less deflection). But how do they work? %%EOF When doing the first maintenance for a new or overhauled engine, conduct valve-clearance checking to timely regulate and correct the initial changes of the valve clearances. On a 6 cylinder model #1 and #6 cylinders rise and fall together from TDC (top dead center) to BDC (bottom dead center). When rotating the fan, there should be no vibration or excessive axial movement. Most people do not realize that we can make subtle performance improvements by slightly reducing or increasing the recommended lash settings. Foley Industrial has built out this helpful guide for torque values and valve settings on Perkins and other engines. Different types of engines have different valve clearances; the same type of engine has different valve clearances in cold and hot states; the same type of engine has different intake and exhaust valve clearances. The heads of the intake and exhaust valves are directly located in the combustion chamber, and the entire head of the exhaust valve is located in the exhaust passage, so the temperature is very high. For example, by reducing the amount of (hot) valve lash, the valve will open slightly sooner, provide slightly more lift (valve opening), and will close slightly later. The double of the double-row no-entry method means that the clearance between the two valves of the cylinder at the top dead center can be adjusted, the row means that the clearance of the exhaust valve of the cylinder can be adjusted, and the no means that the two valve clearances of the cylinder can be adjusted. (4) When the piston of No 1 cylinder is at the TDC on compression stroke, check with a feeler gauge the intake valve clearance of 1, 2 and 4 cylinder, as well as the exhaust valve clearance of No 1, 3 and 5 cylinders. 3-JKj?'{RmHM3F'x3G>gP For engines with the same number of cylinders, if the working sequence is different, the valve adjustment sequence is also different.
