How to adjust the valve of six-cylinder diesel engine

The adjustment of diesel engine valve clearance should be carried out in the cold state, when the valve is completely closed and the valve tappet is lowered to the lowest position. Before adjustment, remove the cylinder head cover, pry the crankshaft according to the rotation direction of the engine, and find out the compression top dead center of the first cylinder.

1、 ? Find the top dead center of cylinder compression:?

Among the six diesel tractors, except LT665, all other models are looking for a cylinder to compress the top dead center. The method is as follows: GBC pry the crankshaft according to the rotation direction of the engine.

2、 ? Identify the intake valve and exhaust valve, and select the clearance value:

There are two ways to arrange the cylinders of diesel engines. In-line cylinders count from front to back. Looking forward from the rear end of the V-engine, the right row is 1, 2, 3, 4, and the left row is 5, 6, 7, 8.

3、 ? Determination of adjustable valve by expression method;

4、 ? Adjust with the specified clearance value:

When calculating the compression top dead center of the cylinder, for the valve that can be adjusted according to the expression method, the thickness gauge should be inserted between the valve rod end and the valve rocker head, so that the thickness gauge can move back and forth slightly and be slightly blocked.
