Caterpillar DP20 MC Forklift Engine Service Manual (99729-96100)

A Cat DP20-series diesel counterbalanced truck moves pallets and materials around the plant, yard, or loading area. This manual is for the mechanic working on the engine when the truck is out of warranty or the shop has inherited it without proper documentation. I've used manuals like this when the repair window is short and guessing costs a weekend. This is the engine book of the set, covering specifications, systems operation, testing and adjusting, disassembly and assembly, torque values, and clearances.

What this manual helps you do

• Trace engine systems and understand how they operate.
• Check engine performance using the stated testing and adjustment procedures.
• Diagnose running, starting, cooling, lubrication, and fuel-system faults.
• Rebuild engine assemblies with disassembly and assembly guidance.
• Verify torque values, clearances, and related service data during repair.

Who this is for

This suits a plant maintenance technician, dealer technician, independent forklift repair shop, or rental fleet mechanic working on Cat diesel trucks. The companion chassis manual, also available, covers the truck-side systems such as the power train, hydraulics, steering, brakes, mast, and forks.
