Your SK135SR has a weeping swing motor seal and the parts counter wants a number before they quote it: this 758-page Kobelco SK135SR, SK135SRL parts catalog PDF (OEM ID S3YY00003ZE04) holds it for the hydraulic excavator, SRLC included. Exploded views take the superstructure, undercarriage and attachments down to the bolt, from slewing ring and track rollers to boom, arm and bucket, each callout tied to a part number. Hydraulic components fill close to a quarter of the book, with the main relief valve, propel motor and swivel joint broken down piece by piece, and wiring diagrams trace the upper harness. Before you order a cartridge, match the main relief valve to its 350 kgf/cm² set pressure at 60 L/min, and port relief F2 to 400 kgf/cm² at 30 L/min. A guessed relief setting can split a hose. Search it, jump by bookmark, or print the valve pages for the bench; grease on paper costs nothing.
