What must be done when installing a new J3-axis reducer?

When installing a new J3-axis reducer, it is essential to ensure that the tapered dowel pin holes are properly reamed by hand. This process is critical because it helps achieve the correct fit and alignment between the reducer and the shaft. Proper alignment is crucial for the reliable operation of the machinery and to prevent premature wear or malfunction.

By hand reaming the holes, you can ensure that there are no irregularities or imbalances that might arise from using a power tool, which could inadvertently introduce deviations or inconsistencies in the holes. This careful approach leads to better seating of the dowel pins, enhancing the overall performance and longevity of the J3-axis reducer.

The other methods mentioned, such as using a power drill for precision, applying grease, or checking alignment with a laser tool, may be part of standard maintenance or installation procedures, but they do not specifically address the foundational requirement of properly preparing the dowel pin holes before installation.
