Crown SP 3400 Parts Catalog

I have watched guys spend half a shift hunting down a part number for a Crown SP 3400 because they were using a reprint or some third-party sketch. That is lost time and lost money. This is the real deal – an OEM Crown SP 3400 Parts Catalog, 210 pages, factory-sourced, with every section from covers to mast cylinders. If you are touching a SP 3400, you want this on your bench, not some PDF scavenged from a forum.

Hydraulic System and Valve Block Coverage

You want to see how deep this goes? The Parts Catalog breaks down the hydraulic system into sections like Power Unit – One Speed Lift and Power Unit – Two Speed Lift, and then goes straight into the Valve Block. There are six different valve block variants: one speed lift, two speed lift, and both with auxiliary lift options. Each one gets its own exploded view with part numbers. Not a generic diagram – specific Crown part numbers. Page 32 shows the Valve Block – One Speed Lift. If you are rebuilding a pump or swapping a valve, you can point to the exact o-ring or cartridge.

Get the Right Part Number the First Time

Aftermarket parts catalogs are garbage for this. I have seen them omit the temperature and brush wear sensor section for the pump motor. This manual includes Pump Motor – Temperature & Brush Wear Sensors. Crown put that in there because those sensors fail and you need the correct replacement. The same goes for the drive motor sections and the steering gearbox. Every part is indexed by serial number cut and revision. You cannot guess with lift truck hydraulics – one wrong seal and you are pulling the mast again. This manual kills the guesswork.

Who Needs a 210-Page Parts Catalog?

If you are a one-man shop maintaining a fleet of SP 3400 walkie stackers, or you are a dealer tech who sees these daily, you need this. The manual covers the mast (TL and TT), the lifting fork cylinder, the platform load deck, and even the pallet grab. For home guys who bought a used SP 3400 at auction – this will save you from ordering the wrong brake pedal or steer motor. The parts catalog does not tell you how to rebuild the brake, but it gives you the Crown part number so you buy exactly what goes back in.

Lifting Mechanism: Mast TL and TT Breakdown

The mast sections are split into three parts each. Mast – TL Part 1 of 3, Part 2 of 3, Part 3 of 3. Same for Mast – TT. That level of detail means you can see every roller, every chain anchor, every section of the mast channel. The Crown SP 3400 uses a two-stage mast on some builds – the manual separates the parts so you don’t mix up TL and TT hardware. Also included: Lifting Fork Cylinder under the Cylinders section. That is a single cylinder but they give you the seal kit number.

Frequently Asked Questions about the Crown SP 3400 Parts Catalog

Does this manual include torque specs for the drive motor bolts?

No. This is a parts catalog, not a service manual. It gives part numbers, exploded views, and quantities. For torque values you need the factory service manual. Use the same caution as any lift truck repair – refer to the service manual for assembly specs.

Can I use this manual to order parts for a Crown SP 3400 built after 2006?

Yes. The catalog covers SP 3400 series and includes revision A from 02/2006. Later production runs may have minor part changes, but the serial number cut columns help you match. Cross-check with Crown dealer if your unit has unusual options.

Does it cover the electrical system?

Yes. Sections include Traction Panel, Distribution Panel, Lift/Power Panel, Control Modules 1 and 2, Switch Panel, Height Sensor, Connectors, and even the control cable for TL and TT masts. Over 20 pages on electrical components alone.

Is this a direct copy of the Crown factory document?

Yes. The manual is scanned from the original Crown document (order number 812727-006, revision A). Every page matches the factory print. No reprint, no missing pages. That is how we sell it.

You can keep digging through catalogs from other brands, or you can get the factory document that matches the truck on your lift. This manual is part of the largest collection of OEM shop manuals in North America.
