Caterpillar P4000 Forklift Component Service Manual (99729-87120)

This Cat P4000 is a counterbalanced forklift for moving loads around warehouses, yards, and plant floors. This manual is the workshop supplement for component-level repair on that truck. A maintenance technician reaches for it when an assembly needs to be diagnosed, dismantled, inspected, adjusted, or rebuilt by the book.

What this manual helps you do

• Diagnose faults in the P4000 component assembly covered by the manual.
• Follow removal, disassembly, inspection, and reassembly procedures.
• Check service data while setting adjustments and verifying component condition.
• Trace related wiring, controls, or mechanical connections during fault finding.
• Rebuild the assembly in the correct service sequence, with the chassis manual as the companion reference.

Who this is for

This suits warehouse maintenance technicians, plant maintenance teams, dealer technicians, independent forklift shops, and rental fleet mechanics working on Cat P4000 trucks. It is a trade workshop manual, while the P4000 chassis service manual and operator handbook are the companion volumes also available. In my experience, having the component procedure beside the truck saves guesswork when the repair gets audited.
