Komatsu Mini Excavator Parts by Model, Number and Cylinder Type

For the PC05-5 and PC05-6, Komatsu parts cover all five primary cylinder components with a 30 mm rod throughout. Bore size is 50 mm for the boom, boom swing, arm, and bucket cylinders, or 60 mm for the blade lift cylinder. The PC10-5 lineup covers the same five cylinder components, and each product page includes a part number. Its boom cylinder (20N-63-56700) uses a 35 mm rod and 70 mm bore.

The bucket cylinder (20N-63-76500) uses the same rod with a 60 mm bore. PC15-2 seal kits cover the boom, arm, bucket, and blade lift cylinders, with boom and arm kits sized at 40 mm rod and 70 mm bore. These Komatsu parts come in a range of options, so you can replace a worn seal without guesswork.
