Characteristics of reaming process of Bare Engine

(1) Select reamer: Bare Engine select reamer according to the standard size of piston pins and clamp the reamer vertically on the bench vise.

(2) Adjust the reamer: Usually, one cut is enough to adjust the blade to expose 3~5mm on the flat surface of the Isuzu Engine

Yes, the future cuts 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 little back cutting will cause the reamer to jump during the reaming process, and the dumplings will have edges or bell mouths.

(3) Reaming: When reaming, hold the small end of the connecting rod with one hand and apply slight pressure downward, hold the large end of the connecting rod with the other hand, and pull the connecting rod evenly in a clockwise direction for reaming. When reaming, ensure that the connecting rod axis is perpendicular to the knife axis to prevent the Isuzu Engine from being biased.
