Which of the following is the recommended method of pulling dry liners from a cylinder block?

Using a puller and shoe assembly is the recommended method for pulling dry liners from a cylinder block. This method is effective because it allows for even force distribution when removing the liners, minimizing the risk of damaging either the liners or the cylinder block itself. The puller provides a mechanical advantage that ensures a secure grip and control during the removal process, which is crucial for avoiding complications that could arise from improper handling.

When using a puller and shoe assembly, technicians can effectively manage any resistance that may be encountered due to factors like buildup of carbon deposits, corrosion, or variation in thermal expansion. This method ensures that the liners are removed in a manner that maintains the integrity of the surrounding engine components, which is essential for maintaining optimal engine performance and preventing the need for more extensive repairs.

Other methods listed are generally not recommended due to their potential for causing damage or complications. For instance, the arc welding method can introduce excessive heat, leading to warping or cracking. The heat and shock cool method involves thermal stress which can potentially damage the cylinder block. Fracturing the liner in position can create debris and lead to further complications in the engine assembly. Therefore, the puller and shoe assembly stands out as the safest and most efficient technique in this scenario.
