Engine block must be flushed (fig. 1)
Preparing to assemble the engine parts.
We press the front crankshaft oil seal into the front cover (Fig. 2).
Outside, on the front cover there is an engine speed limiter (Fig. 3).
We remove all the insides from the speed limiter and put a solid gasket and attract with the body.
We screw the studs for mounting the fuel pump into the front cover
At the factory, the fuel pump is bolted on. We install studs (Fig. 4), which will eliminate unnecessary problems in subsequent operation.
It happens that when a bolt is lost, a larger bolt is installed and this bolt rests against the camshaft gear, which leads to wear of the camshaft gear (Fig. 5)
Preparing the crankshaft. If the shaft was bored, then we blow the channels after boring with compressed air
We twist the technological plugs of the oil channels (Fig. 6).
We countersink the holes on the shaft with a ball from the bearing (so that there are no sharp edges on the working part of the shaft bearing (Figure 7)).
On the back of the crankshaft, an oil-fighting thread can be applied, in the place where the shaft is pressed against the packing (fig. 8). This increases the tightness of this joint.
Inspect and grind, if necessary, the camshaft (Figure 9)
If we remove the inside of the speed limiter, then we modify the bolt that secures the camshaft drive gear
Use a grinder to cut off the rolling of the flag and remove the flag and spring. Get bolt 2, as in the figure (Figure 10)
This is done so that the bolt flag does not rest against a solid gasket under the rev limiter housing.
In order not to make a mistake when assembling and installing gears, it must be taken into account that the mark on the crankshaft gear is on the 12th tooth, counting from the tooth opposite the slot for the key counterclockwise (Figure 11).
We press in the babbitt bushings of the camshaft (of course, steel-aluminum bushings can be used) (Figure 12)
To press the bushings, we use a tool (Figure 13)
