E-P Equipment CPCD50, CPCD60, CPCD70, CPCD80, CPCD100 2007 Service Manual

I’ve been turning wrenches for 28 years, and I’ve seen more half-assed repairs on forklifts than I care to count. The problem is always the same: someone guessed a torque value, used a generic wiring diagram, or skipped the bleed procedure. That’s why when you’re working on a 5–10 ton R-series — whether it’s a E-P Equipment CPCD50, CPCD60, CPCD70, CPCD80, or CPCD100 — you need the factory book. This 2007 Service Manual is the real deal: 92 pages of OEM data, written by the people who built the truck. No aftermarket translation errors, no missing pages. Just the specs you need to do the job right the first time.

Torque Converter and Gearbox: The Heart of the Drive

Chapter 2 covers the hydraulic gear-box and torque converter. If you’ve ever had a forklift that surges or won’t engage, you know the transmission is the first thing to check. This manual walks you through the converter removal, seal replacement, and the exact torque sequence for the bell housing bolts. For the charge pressure spec, see page 2 — it’s given in psi, not some converted metric guess. The R-series uses a counter-shaft transmission with a single-stage torque converter; the manual lists the pump flow rate and the stall test procedure. You won’t find that in a Chilton book.

Transmission Axle: Disassembly and Reassembly

Chapter 3 is the transmission axle — that’s the drive axle on these trucks. The manual includes the shim selection process for the differential pinion depth, and the bearing preload specs. Page 73 (yes, I said page 73) gives the final drive gear backlash: 0.008–0.012 inches. If you set that wrong, you’ll be pulling the axle again in 500 hours. The section also covers the parking brake adjustment inside the axle housing — a step most techs skip because they don’t have the factory tool specification. The manual tells you the exact tool diameter to use for the brake shoe gauge.

Brake System: Factory Procedure for Safety

Chapter 7 is the brake system. I’ve seen brakes bled with a bottle and a hose, and the pedal still goes to the floor. This manual gives the bleed sequence for the dual-circuit hydraulic system, the master cylinder pushrod clearance (0.5mm), and the brake fluid specification (DOT 3 or 4, not some off-brand garbage). The parking brake adjustment procedure requires a specific clearance between the lever and the cam — the manual provides the measurement in inches. Safety first: the manual also warns against using compressed air to clean brake components without proper PPE. That’s the kind of detail that keeps a shop out of a lawsuit.

Hydraulic System Troubleshooting: Page 36

Chapter 8 covers the hydraulic system. The lift and tilt circuits are the most common failures on these trucks. The manual includes a troubleshooting table that lists symptoms — slow lift, drift, noisy pump — and the likely causes with page references to the repair procedures. The control valve disassembly is explained step by step, with the relief valve pressure setting (factory spec: 2100 psi). The manual also shows the correct way to prime the hydraulic pump after replacement; if you skip that, you’ll burn the pump in ten minutes. I’ve watched it happen.

Electrical System Diagnostics: Page 42

Chapter 9 is the electrical system. Wiring diagrams are included for the starter circuit, alternator, and the seat switch interlock. The manual gives the voltage drop specs for the main power cables (less than 0.5V at full load) and the starter solenoid pull-in current. If you’re chasing a no-crank condition, the troubleshooting tree on page 42 will save you an hour of poking around with a test light. The manual also covers the glow plug system for the diesel engines, including the resistance values and the controller check procedure. No guesswork.

Who Needs This Manual and Why

If you’re a home garage enthusiast who bought a used CPCD50 to move machinery around your property, this manual is for you. The factory diagrams show you how to adjust the steering axle (chapter 5) and the steering system (chapter 6) without taking the whole truck apart. For a professional mechanic, this manual cuts your diagnostic time in half. The appendixes (A and B) contain the maintenance schedule and the bolt torque charts for all major fasteners. You don’t have to wonder if a bolt is M14 or M16 — it’s listed with the torque in ft-lbs. And since the manual is OEM, the torque values are certified by the manufacturer. I’ve seen aftermarket books list the wrong torque for the cylinder head bolts on the LR4108 engine — that’s a head gasket failure waiting to happen.

Source Authenticity: OEM vs. Aftermarket

This is a factory scan of the original 2007 printed manual from E-P Equipment Co., Ltd. The PDF is a direct copy of the 92-page book, not a third-party rehash. The table of contents matches the physical manual exactly. When you buy this, you’re getting the same documentation that a dealership technician would use. The manual includes the foreword that explicitly warns: “Forbid repairing the truck if you haven’t been trained.” That’s not a disclaimer — it’s a safety directive. The OEM spec ensures that the torque converter removal procedure, the transmission axle shim selection, and the brake system bleeding sequence are all correct. I’ve used aftermarket manuals that skipped the entire steering axle section. This one doesn’t.

Does this manual cover the CPCD80 and CPCD100 models?

Yes. The manual covers CPCD50, CPCD60, CPCD70, CPCD80, and CPCD100. The R-series variants (RG16, RW28, etc.) are all listed in the front matter.

Are the torque values in imperial units?

The manual gives torque values in N·m, but you can convert. The backlash and clearance specs are in millimeters. For example, the differential backlash is 0.2–0.3 mm (0.008–0.012 in). The manual is metric, but every pro knows the conversions.

What about the LPG versions (CPQD models)?

The manual includes CPQD50/60/70-RW17-Y in the model list. The fuel system differences are covered in the engine section (refer to the engine maintenance manual for the specific engine). The forklift service procedures are identical for the chassis and hydraulics.

Does the manual include wiring diagrams for the electrical system?

Yes. Chapter 9 (Electrical system) includes full wiring diagrams for the starter, alternator, and safety interlocks. The manual also provides the voltage drop test procedure and the glow plug resistance values for the diesel engines.

You’ve read the specs. You’ve seen the chapter breakdown. Now stop borrowing a beat-up copy from a buddy and get your own. Access the Factory Manual from AutoRepairManuals. It’s the same 92-page OEM document that E-P Equipment issued in 2007. No missing pages, no aftermarket errors. Just the data you need to keep that CPCD50 or CPCD100 running like it should.
