Komatsu PC30MR-3 Rubber Tracks

The Komatsu PC30MR-3 uses 300x52.5Kx86 rubber tracks (Width: 300mm, Pitch: 52.5mm, Links: 86). Always verify the size stamped on your existing track or use the TrackTECH Rubber Track Finder before ordering.

Matching drive sprocket options for the Komatsu PC30MR-3 include Komatsu PC30MR-3 Sprocket | Part #1032265. When installing new rubber tracks, inspect sprockets for hooked, sharp, or uneven teeth because worn sprockets can shorten track life and damage the drive lugs.

Matching bottom roller or track roller options for the Komatsu PC30MR-3 include Komatsu PC30MR-3 Track Roller | Part #4340535. Replacing worn rollers before installing new rubber tracks helps keep the undercarriage aligned and reduces uneven wear across the track carcass.

Matching top roller options for the Komatsu PC30MR-3 include Komatsu PC30MR-3 Carrier Roller | Part #9237948. Top rollers support the upper track path and should be checked for bearing play, flat spots, and uneven wear during undercarriage service.

The 300x52.5Kx86 rubber track size is used across multiple compact machines, including 300x52.5Kx86, Case CX37C, Case CX33C, Hitachi EX40UR-3, Hitachi UE35, Hitachi ZX35U-5, Hitachi ZX33U, and Hitachi ZX30U. Always confirm by checking the size stamped on your current track and your machine serial number before ordering.

Yes, inspect sprockets, rollers, and idlers before installing new rubber tracks on the Komatsu PC30MR-3. Worn undercarriage parts can shorten track life, cause poor alignment, and create uneven wear. Shop matching parts from the linked products above or view all undercarriage parts.

Confirm fitment by checking your machine make, model, serial number, and existing track size or OEM part number. For rubber tracks, verify width, pitch, and link count.
