Curator's pick: Liner Puller Tool for Cummins N14
Without this specific tool, you risk scarring the block or wasting hours with makeshift pry bars. It provides the consistent vertical force required to pop stubborn sleeves without the drama often found in generic universal kits.
⚠ Worth knowing: Using the assembly lubricant and stabilizer is mandatory for the initial break-in period, but if your block's counterbores are already pitted or out of spec, no kit in this list will prevent a premature head gasket failure.
