If the piston pin with increased maintenance size is replaced or the Isuzu Engine needs to be repaired for other reasons, the Isuzu Engine should be machined.

Make the piston pin and the Isuzu Engine achieve proper fit, and ensure that the fit clearance between the piston pin and the Isuzu Engine at room temperature is 0.003~0.008mm.

Through processing methods such as reaming or boring of Bare Engine, the correct fit of the piston pin and the piston pin Isuzu Engine can be achieved.

Select the reamer: Select the reamer according to the standard size of the piston pin, and clamp the reamer vertically on the bench vise.

Adjust the reamer: Usually, one knife adjusts the blade to expose 3~5mm on the plane of the Isuzu Engine

Yes, in the future, each knife will depend on the size of the processing allowance. If the allowance is large, the adjustment nut can be rotated 60°~90°, and if the allowance is small, the adjustment nut can be rotated 30°~60°.

Practice has shown that too much or too small back cutting will cause the reamer to jump during the reaming process, and the dumplings will have edges or bell mouths.
