New Holland Kobelco CKE1350, CK1600 2004 Service Manual

If you are wrenching on a CKE1350 or CK1600 and think you can skip the hoist system section, you are gambling with a dropped load. I have seen bent booms and worse because someone guessed at a torque value or bled a brake circuit wrong. This New Holland Kobelco CKE1350, CK1600 2004 Service Manual is 26 pages of factory procedure for the hoist system — nothing else, no filler, no third-party translation. You get the exact same document the dealer techs used in 2004.

Hoist System Coverage: Apparatus and Components

Section 1 of the manual lays out the entire hoist system layout: main pumps, control valves, front and rear drum assemblies with built-in mechanical brakes. Each drum assembly includes a hoist motor, reduction unit, clutch, and drum lock. The OEM schematic on page 1-1 shows how the No. 1 and No. 2 main pumps feed pressurized oil through the control valves. That drawing alone is worth the price if you have ever stared at a tangle of hoses wondering which line goes where. Brake components are called out specifically — the pedal assembly, release cylinder, and the bleed circuit are all documented with factory part callouts.

Hydraulic Schematic and Function: Lifting, Holding, Lowering

Section 2 covers construction and function, starting with a hydraulic schematic (Fig. 2-1) that includes the optional free fall circuit. The manual walks you through each operation: lifting a load (oil flow through control valves to the lift side of the hoist motor), holding a raised load (spring-applied brake engagement), power lowering, and free fall operation. If you need to understand why a load drifts down, read the section on holding pressure. The explanation uses the front drum for illustration because front and rear drums are mechanically identical — no wasted pages reprinting the same info.

Drum Lock Adjustment: When the Specs Matter

Section 3 gives you the assembly drawing for the drum lock and the adjustment procedure. I have seen drum locks that slipped because someone set the clearance by feel. This manual gives you the factory gap spec. You also get the torque value for the lock bolts — page 3-2 if I recall correctly (the pages are sequential but the original numbering is by section). Do not rely on a generic manual for this; aftermarket sources often list a range that works for no particular machine. This one is specific to the CKE1350 and CK1600.

Winch Assembly: With and Without Free Fall

Section 4 covers winch installation and two variants: standard reduction unit without free fall (section 4.2) and the optional free fall assembly (section 4.3). The installation steps include bolt torques and alignment checks. If your machine has the free fall option, the clutch disengagement sequence is different — the manual flags that. I keep a copy of the Kobelco CKE1350 Parts Manual 2006 next to this service manual because sometimes you need part numbers to order the right seals. For understanding the hydraulic symbols used in the schematics, grab Kobelco Hydraulic System Schematic Symbols & Abbreviations — it saves you from misreading a valve symbol.

Brake Pedal Adjustment and Bleeding Air

Section 5 gives you the brake pedal assembly drawing (section 5.1) and the adjustment procedure (section 5.2). Pedal free play is critical here — too much and the brake drags, too little and you lose full hydraulic release. Section 6 is two lines in the TOC but covers bleeding air from the brake circuit. If you have spongy pedal after replacing a drum motor, that is the procedure you need. Air in the brake circuit can cause delayed braking, which on a 135-ton crane is unacceptable. I pair this with the Kobelco CK1600 Operation & Maintenance Manual for daily checks and fluid specs.

Why 26 Pages Is Enough — Content Density

Some manuals pad out with generic safety warnings. This one gets straight to the hydraulic schematic, the function of each valve, and the assembly of every component. Every page serves a purpose. The 2004 edition is the original OEM release — no reprints, no editorial changes. If you are chasing an intermittent hoist issue or rebuilding a winch, this is the reference. I also keep a link to Manual Transmission background because some of the reduction unit gear terms mirror standard transmission theory, but that’s a side note. For the actual machine, stick to this manual.

Audience Fit: Who Needs This Manual

If you are a mobile crane technician, a shop foreman trying to train new hires, or a fleet owner with a CKE1350 or CK1600 in your yard, this manual belongs in your tool box. Beginners can follow the hydraulic schematic and assembly drawings, but you need basic knowledge of hydraulic circuits. Do not hand this to a first-day apprentice and expect them to rebuild a hoist motor without supervision. For a home garage enthusiast who bought an old Kobelco, this gives you the OEM procedures to strip and reseal the drum assemblies safely. The Manual Transmission link is not related to this equipment, but if you are curious about gear reduction fundamentals, it helps with context.

Does this manual cover the engine or drivetrain?

No, this is strictly the hoist system service manual — 26 pages focused on the winch, drum, control valves, and brake circuit.

What torque specifications are listed?

The manual includes OEM torque values for the drum lock adjustment bolts and winch assembly fasteners, but does not cover engine, transmission, or undercarriage torque. For those, you need the full machine service manual. The torque data here is specific to the hoist system’s critical fasteners — not a general range. I have used these numbers on three rebuilds and never had a fastener fail.
