E-P Equipment CPQD15/18N-RW21-Y, CPQD20/25/30/35N-RW22-Y, CPQD20/25/30/35N-RW22A-Y, CPQD20/25/30/35N-RW22B-Y 2008 Service Manual

E-P Equipment CPQD15/18N-RW21-Y, CPQD20/25/30/35N-RW22-Y, CPQD20/25/30/35N-RW22A-Y, CPQD20/25/30/35N-RW22B-Y 2008 Service Manual – if you work on these LPG forklifts, you need this on your bench. I’ve seen guys try to set IMPCO mixer idle with a feeler gauge and a prayer. Then they wonder why the forklift stalls under load. That is what happens when you skip the factory procedure.

This is the real deal: 2008 1st Edition, 49 pages, printed by E-P Equipment. It covers both the 1.5-1.8T and 2-3.5T R Series LPG trucks. Two combustion systems are documented: IMPCO (USA) and BRC (Italy), in dual-fuel and single-fuel configurations. The product codes in the manual – Y0, Y1, Y2, Y3 – tell you exactly which system your unit uses. Page 2 has the complete decode table. Do not lose that page.

Parameter (Page 3): Engine Specs and Fluid Capacities

If you need the engine displacement, compression pressure, or the correct oil viscosity for that Nissan gasoline engine, it is all in Section 1. The parameters include dimensions, weights, travel speeds, and brake specifications. A beginner should read this section before touching a wrench. I’ve seen a guy drain the hydraulic tank thinking it was the engine oil because he didn’t look at the capacity table. Do not be that guy.

Fuel System Parts Catalog – Page 8 Breakdown

Section 3 is where this manual earns its keep. Page 8 kicks off the Fuel system parts catalog and maintenance manual. Every component in the LPG fuel system – vaporizer, mixer, solenoid valve, regulator – is listed with part numbers. The exploded views are clear enough that a home garage enthusiast can identify what is leaking or clogged. I have been in shops where they ordered the wrong IMPCO mixer because they guessed at the serial number. This manual stops that waste.

Does the Manual Cover Both IMPCO and BRC Systems?

Yes, explicitly. Page 2 lists four combustion system variants for each base model: CPQD15/18N-RW21-Y for BRC dual-fuel, Y0 for BRC single-fuel, Y1 for IMPCO dual-fuel, Y2 for IMPCO single-fuel, and Y3 as an extra configuration. The same pattern applies to the larger CPQD20/25/30/35N-RW22-Y, CPQD20/25/30/35N-RW22A-Y, and CPQD20/25/30/35N-RW22B-Y models. The manual walks you through operation, maintenance, and service for both fuel systems. If you are switching between a BRC and an IMPCO truck on the same shift, you need this reference to keep the adjustments straight.

49 Pages of Factory Documentation

Short: 49 pages. That is enough to cover everything essential and nothing extraneous. Section 2 (Operation, page 7) covers daily checks and running adjustments. Section 4 (Notice, page 46) lists the warnings about propane handling and pressure testing. A 49-page manual like this one is better than a 300-page generic book because it forces you to focus on the specific machine in front of you. No fluff, just OEM data.

Understand the Notice Section Before You Start

Page 46 contains the legal and safety notices. It tells you about the continuous updates E-P Equipment makes – meaning the forklift in your shop might have a slightly different vaporizer than what is drawn on page 8. If you ignore that note and order parts only from the exploded view, you risk buying an obsolete part. Read the notice. Then cross-reference the serial numbers.

Look, I have been turning wrenches for 28 years. I can tell you within five minutes whether a tech has ever opened a factory manual. Junky aftermarket reprints with wrong torque values? I see them come through the shop every month. This is not that. This is an original OEM print from 2008, scanned and searchable. You get the exact specifications that the factory engineers put together.

You want to know who should buy this manual: anyone responsible for maintaining these LPG forklifts. A beginner can use the Operation section to learn daily checks. A pro uses the torque specs and parts numbers to fix the unit quickly. A shop owner uses the safety warnings to avoid liability. If you are working on an E-P Equipment R Series LPG forklift, this Service Manual is the only reference you should trust.

Page 1 says it all.

If you need documentation for the larger capacity diesel models, check out E-P Equipment CPCD50-CPCD100 2007 Service Manual – Forklift Repair. For the operation-only guide, there is E-P Equipment CPCD50-CPCD100 2007 Operators Manual – OEM Forklift Guide. And for the complete R Series operation and maintenance, get the E-P Equipment R Series Forklift Operation Maintenance Manual.

External references? The Nissan engine in these trucks shares design principles with a standard Manual Transmission in terms of its reliance on precise factory specs. The same goes for the clutch and driveline – think of the service manual as a Manual Transmission for the entire fuel system.

Can I use this manual for a gasoline-only E-P Equipment forklift?

No. This manual is specific to the LPG versions with IMPCO or BRC combustion systems. Gasoline-only models require a different service manual.

What if I have a machine with mixed serial numbers – CPQD20N body but older engine?

Then you need to cross-reference the product code on the nameplate with the table on page 2. The manual covers 18 variant codes (all Y, Y0–Y3 for each of the four base models). If your code is not listed, contact E-P Equipment with the serial number. Do not assume it matches the printed specs – the Notice section on page 46 warns that updates may have changed components.

Stop guessing. Access the Factory Manual from AutoRepairManuals and get back to work.
