This 678-page Takeuchi TB138FR Workshop Manual (OEM #CG5E001) covers your Compact Excavator down to the last O-ring, from the YDP-MP2 and YDP-MP4 engine variants right through to the drive, slew, and travel systems. You get full wiring diagrams for chasing electrical faults, hydraulic schematics that trace pump, control valve, and cylinder circuits, plus a dedicated troubleshooting section built around real symptoms: won't slew, won't travel, boom drifts. Check carrier roller wear against the factory allowable value of 69 mm before you condemn a part, and follow the piping cautions on reassembly so you're not chasing a leak you created yourself. No more guessing whether that roller is still within spec. This PDF is bookmarked and searchable, so you can jump straight to Section IV or the engine chapter, pull it up on your tablet, and get back under the machine.
