Looking for a Case 1650K service manual PDF with real factory data? All 319 pages of this workshop manual (OEM #6-46470) cover the Case 1650K Crawler Dozer, from the engine and torque converter through final drives, undercarriage, and dozer hydraulics. You get hydraulic schematics for the blade and ripper circuit, wiring diagrams for the electrical system, and page after page of exploded views spanning the transmission, brakes, and steering differential. Open the transmission section and you're straight into clutch, modulating valve, and torque converter rebuild procedures. Tighten the torque converter securing screws to 6.8 to 7.4 daNm (50.15 to 54.58 ft lbs), and hold spool-to-seat clearance at 0.22 to 0.25 mm. Your dozer is down and daylight is burning. Bookmarked PDF that opens on any device; carry your tablet to the machine and start wrenching.
