Kioti CK25, CK25H, CK27, CK27H, CK30, CK30H, CK35, and CK35H Tractor Workshop Manual 2008 (P/N D704-W01)

This Kioti/Daedong workshop manual, P/N D704-W01, June 2008 edition, covers CK25, CK27, CK30 and CK35 tractors and their CK25H, CK27H, CK30H and CK35H hydrostatic counterparts.

Searchable Text and Wiring Diagram Detail

Search, bookmarks and small labels: The main manual text supports PDF searches. Embedded bookmarks reach the main sections, although most use numbered Korean filenames rather than English chapter names. The dense main wiring diagram requires enlargement to read small wire codes and terminal labels.

One printable 402-page PDF, including the original cover, 16 blank pages and six ruled memo pages already included in the total.

Engine, Drivetrain and Hydraulic Service

The following selected coverage highlights outline the main workshop content. Other topics include tire ballast and unit conversion tables.

• Engine repair: Compression testing, cylinder-head and valve service, timing-gear installation, piston and crankshaft removal, and internal wear inspection.

• Fuel and cooling systems: Bosch K-type injection-pump removal, injection-timing adjustment, nozzle testing, radiator pressure checks, thermostat testing and water-pump replacement.

• Clutch and transmission: Tractor splitting, clutch inspection, synchro-shuttle disassembly, optional creep gearing, and rear and optional mid-PTO service.

• HST diagnosis and overhaul: Drive-fault troubleshooting charts, charge and high-relief pressure checks, pump and motor disassembly, and pedal-damper adjustment.

• Axles and wet disc brakes: Front differential overhaul, bevel-gear backlash and bearing-preload adjustment, rear axle removal, brake disassembly and disc-wear checks.

• Steering and lift hydraulics: Gerotor steering-unit rebuilding, tandem-pump disassembly, joystick-valve inspection, and lift control (MLS) valve and linkage adjustment.

• Electrical troubleshooting: Wiring diagrams, starting and charging circuit diagnosis, glow-plug and relay tests, and instrument-sender checks.

Written for servicing personnel, this manual includes internal overhaul work and hydraulic tests that require workshop equipment and component-measurement skills.

Engine Inspection, Injection and Cooling

The engine sections cover the TD1300 and 3A139/3A150/3A165 families. Cylinder-bore measurements, piston-ring end gaps and crankshaft-bearing clearances are accompanied by factory specifications and allowable limits, helping a shop assess worn components before planning replacement.

Step-by-step procedures cover separating the engine and clutch housing, internal engine disassembly and reassembly. The illustrated timing-gear marks matter: the manual warns that misalignment can cause severe engine failure.

Injection timing is checked with the engine installed, with shim-based adjustment and a reference to DAEDONG special tool kit G0611-B0010. Internal injection-pump disassembly is reserved for authorized service personnel and requires delivery adjustment on a designated test bench.

Cooling coverage includes radiator-cap leakage checks and thermostat opening tests. For the water pump, the manual recommends replacing the complete assembly because internal disassembly and assembly require special equipment.

Clutch, PTO and Axle Inspection

The drivetrain coverage distinguishes the manual models’ dual clutch from the HST models’ single clutch. Inspection goes beyond pedal adjustment to release-lever height, clutch-disc wear, pressure-plate flatness and spline backlash.

PTO power train diagrams distinguish manual and HST layouts. Differential service includes shim placement and tooth-contact assessment; front axle work includes tapered-bearing preload and floating-seal installation. The brake chapter also covers the EU handbrake cable.

HST, Steering and Lift Faults

HST troubleshooting charts address failure to move, loss of power, overheating and failure to stop in neutral. Hydraulic circuit diagrams and the steering hydraulic schematic connect the diagnostic checks with the affected flow paths and assemblies.

The steering assembly drawings identify the small check ball in the deepest end-cap bolt hole and the Gerotor timing relationships. Incorrect rotor, shaft and spool alignment prevents proper steering-motor operation.

Joystick coverage explains float, bucket regeneration and load-check functions. MLS service includes power-lift fault diagnosis, cylinder inspection, position-control settings and draft-control adjustment where fitted. Worn speed-control valve internals require replacement of the complete valve.

Electrical Fault Tracing and Scheduled Service

The main circuit diagram and combination-meter circuit are supported by wire-color identification and terminal references. Component tests address the stop solenoid, starter motor, preheat controller and fuel-level sender, giving a shop checks to use alongside the circuit troubleshooting tables.

The maintenance schedule is backed by filter service, lubrication, fluid changes and fuel-system bleeding procedures. Review the opening OEM safety precautions before working with high-pressure hydraulics, batteries or a split tractor.

Examples of Valve Settings and Head Fastener Data

Cold valve clearances: The 3A139 and 3A150 tables specify 0.25 mm intake and 0.30 mm exhaust. The TD1300 specification gives 0.1 mm for both intake and exhaust.

Cylinder-head screws: For 3A139/3A150/3A165 engines, the servicing section lists 103.0–107.9 Nm with oiled threads, staged tightening and an illustrated tightening sequence.
