What is the first step in replacing the master link on an old chain?

Moving the master link into an accessible position is the first crucial step in replacing the master link on an old chain. This action allows for proper access and visibility, which are essential for safely and effectively removing the old master link without causing damage to the rest of the chain or associated components. By positioning the master link appropriately, the technician can more easily manipulate it, ensuring a smoother process for replacement.

In contrast, removing the entire chain would be unnecessary and overly complicated when the goal is simply to replace the master link. Lubricating the master link before accessing or replacing it does not make sense, as the focus should first be on positioning it correctly for removal. Cutting the chain is an extreme measure that would result in additional work and material waste, deviating from the procedure unless absolutely necessary due to chain damage. Thus, moving the master link into an accessible position stands out as the logical first step in the replacement process.
