Part of the Case Repair Manuals.
All 80 pages of this Poclain 600 CK Technical Manual PDF (OEM #S406321) cover one machine: the 600 CK crawler excavator, from undercarriage to boom tip. You get full hydraulic schematics for the high and low pressure circuits, wiring diagrams for the electric circuit (batteries, relay, preheater plugs, alternator, starter), and component breakdowns of the HP power pump, modulator assembly, and 3 S 30 valve bank. Undercarriage coverage runs from the pinion-type reduction gear to the idler tensioning shock absorber. Follow the factory pressure-setting procedure to set the S30 relief valves, dial in the regulators, and confirm swing and track drive pressures before your excavator goes back to work. These old Poclains don't forgive guesswork. Bookmarked PDF that opens on any device; take your tablet to the machine and start wrenching.

Poclain 600 CK Common Problems This Manual Covers
Hydraulic oil weeping from the swing joint, puddle under the upper structure after parking overnight
Clean the swing joint area completely, then run each hydraulic function for 5 minutes and trace where fresh oil appears. Oil weeping between the rotating faces means worn swing joint seals and O-rings; replace them as a set, not one at a time. The upper structure layout on page 10 shows the joint position relative to the hydraulic fluid tank.
Manual Section: Upper Structure p. 10Several automatic lubrication points dry, grease not purging from bearing ring or track roller fittings
Remove the line from each dry point and hand-grease the fitting until clean grease purges from the bearing. A fitting that takes no grease at all is seized; replace it. Trace the lubrication line back for crushed or blocked sections using the roller bearing ring layout on page 11, then recheck every point after 10 hours of operation.
Manual Section: Roller Bearing Ring p. 11Frequently Asked Questions
What is the total hydraulic fluid capacity of the Poclain 600 CK?
The total capacity of the hydraulic circuit for the Poclain 600 CK is 1600 litres, while the capacity of the tank itself is 1100 litres. p. 30
How do you fix poclain 600 CK boom slow and weak, won't lift rated load even with engine at full throttle?
Check main relief pressure at the S30 valve bank following the pressure-setting procedure on page 73, with a 0 to 400 bar gauge on the test port. If pressure creeps down under load, pull the relief valve and inspect the seat for wear, then check pump seals for external leakage before condemning the pump. p. 73
How do you fix hydraulic oil overheats after an hour of digging, power fades until the machine cools down?
Clean the hydraulic oil cooler core first: blow it out from the fan side with compressed air held under 90 PSI (620 kPa). Verify oil level with the machine parked level and cylinders retracted. Foamy oil in the tank means aeration; tighten the suction line fittings at the pump inlet, then recheck temperature after a test run. Cooler details start on page 55. p. 55
How do you fix sluggish, inconsistent hydraulic response on all circuits, spools feel normal but functions drift under load?
Test for internal leakage before pulling the valve bank: hold a loaded bucket off the ground and watch the cylinders; drift over 25 mm (1 inch) per minute points to worn spool bores or seals. Trace the affected circuit on the hydraulic schematic, then match seal kits against the parts diagram on page 32 before ordering. p. 32
How quickly can I access this Poclain 600 CK manual after buying?
