Technical notes
The 211-7826 is a 170 mm-bore cylinder liner for Caterpillar's 3500 family of large-bore diesel and gas engines, including the 3508, 3512 and 3516 (and the 3512B marine variant). The liner is a replaceable wet sleeve pressed into the engine block; the piston and ring pack run against its honed cross-hatched bore, which the iron casting protects against wear while transferring combustion heat to the surrounding coolant jacket. One liner is required per cylinder. Caterpillar has assigned newer part number 523-8663 to this position, and 211-7826 itself supersedes the earlier 110-6993, 8N-6861 and 118-9494 liners. When ordering, confirm the specific 3500-series build and configuration, since the family spans diesel, gas (G3500) and marine ratings, and pair the liner with the correct seals and packings during installation.
