CASE Construction CX16B, CX18B Mini Excavator Service Manual 9-88670 English
$ 17.99 USD
Official Manual Overview
Command the intricate hydraulics and tight-quarter performance of the CASE CX16B and CX18B Mini Excavators with this uncompromising OEM Service Manual. Far exceeding basic maintenance charts, this master reference provides dealership-level technicians with complete teardown and reconstruction metrology for both the standard fixed-frame and the advanced adjustable crawler width undercarriage configurations. It enforces strict diagnostic baselines for the equipped YANMAR 3TNE74 1.006L diesel engine and demands absolute mathematical precision when calibrating the variable displacement axial-piston hydraulic pumps, dictating an exact 210 kgf/cm² (2990 psi) main relief threshold and strict 280 kgf/cm² (3980 psi) overload limits for the boom and dozer circuits. From rebuilding the two-speed planetary travel motors to mapping the complex internal logic of the 10-spool multiple control valves, this guide delivers the exact factory-grade parameters required to eradicate pressure loss, diagnose CAN/electrical harnesses, and restore flawless trenching precision.

Core Selling Points
- Surgical Hydraulic Core Metrology: Rebuild the machine's fluid power heart with absolute factory precision. This manual dictates the exact internal teardown sequences for the main hydraulic pump and 10-spool control valves, enforcing critical torque specifications such as 103.9 ± 10.4 Nm for the pump’s V2 capscrews and a delicate 3.92 to 4.9 Nm specification for the internal spools, preventing catastrophic casing warpage and internal hemorrhaging.
- Complete Yanmar Engine Reconstruction: Unlike standard chassis-only manuals, this volume features a massive dedicated section for the complete mechanical overhaul of the equipped Yanmar TNE series diesel engines. It demands absolute mathematical certainty from machinists, establishing a strict 0.090 to 0.271 mm tolerance for the crankshaft thrust gap and enforcing a 0.610 to 0.778 mm baseline for piston top clearances to restore peak compression.
- Planetary & Slew Motor Overhauls: Stop throwing away expensive travel and swing drives. The literature guides technicians through the microscopic breakdown of the reduction gears and hydraulic motors, demanding an exact 42 Nm fastening torque when mating the slew motor to the gearbox housing, while detailing the exact extraction sequence for the roller gerotors, distributor plates, and brake disc packs.
Features & Highlights
- Dealership-Tier Pressure Calibration: Equip your workshop to tune the hydraulic architecture using specified 500 kgf/cm² (7110 psi) gauge kits. Mechanics are explicitly instructed to calibrate the P1 and P2 main relief circuits to a precise 210 kgf/cm² (2990 psi) standard, and strictly adjust the boom and dozer port relief valves to an aggressive 280 kgf/cm² (3980 psi) to guarantee maximum trenching breakout force.
- Deep-Level Electrical Interrogation: Bypass parts-cannon diagnostics with comprehensive wiring matrices. The guide completely maps out the Sequence Box (E-14) and relay networks, providing specific multimeter benchmarks—such as verifying exactly 12V across the yellow and black wires of the CN-109F connector to instantly isolate a failed two-speed travel solenoid from a severed chassis harness.
- Sequential Symptom Flowcharts: Navigate elusive operational failures with highly logical "YES/NO" diagnostic trees. Troubleshoot "Incapable of Travel" errors by sequentially checking the 35 kgf/cm² (500 psi) pilot pump secondary pressure, verifying the No. 2 fuse integrity, and measuring the exact liter-per-minute internal drain rate of the travel motors to definitively condemn a scored spool or a blown seal.
Problem Solver
- Cures Phantom Starting & Smoking Issues: Troubleshoot Yanmar injection failures scientifically. The text provides exact mathematical formulas for shimming the injection nozzles, explicitly stating that increasing the pressure adjusting shim by exactly 0.1 mm will raise the indirect injection pressure by 7 to 10 kgf/cm², instantly curing black exhaust smoke and erratic idling.
- Resolves Destructive Track Throwing: Recover from severe undercarriage degradation on both the fixed-frame and adjustable crawler width configurations. The manual establishes strict wear limits for the lower rollers and idlers, while mandating the crawler tension droop be precisely adjusted to a 35 to 45 mm window using the grease cylinder, ensuring flawless stability on steep grades.
- Eradicates Unexplained Overheating: Eliminate hidden thermal events that threaten the engine block. Exhaustive procedures guide builders through testing the wax-pellet thermostat by submerging it in heated fluid, requiring physical verification that the valve initiates opening precisely between 69.5°C and 72.5°C and achieves an 8.0 mm minimum lift at 85°C.
Important Pre-Purchase Advisories
- Comprehensive Chassis & Engine Volume: This specific OEM manual serves as the ultimate all-in-one technical blueprint. It exceptionally combines the exhaustive chassis systems (hydraulics, cab electronics, adjustable undercarriage) with deep, micrometer-level internal rebuild data for the Yanmar diesel engine series, eliminating the need to purchase a separate engine overhaul book.
