HIAB BZZ 250-135 2009 Parts Catalog

If you’ve ever ordered a replacement cylinder for a HIAB BZZ 250-135 and ended up with the wrong bore size or mounting bracket, you know the headache. That’s why this factory Parts Catalog exists — so you pull the right part number the first time. This is the 2009 edition, 23 pages, straight from HIAB. No reprints, no third-party guessing. Here’s what you get: exploded diagrams with OEM part numbers for every component, from the support frame to the electric safety valve. I’ve torqued enough bolts to tell you that guessing part numbers costs time and money. Use the real deal.

Liftchassis and Platform: Part Numbers for the Foundation

Chapter 1 covers the liftchassis with itemized parts like the lift arm (Part No. 67463, L=1350 mm), pivot bolts, and bumper bar assembly. Page 2 lists each component with quantity. Chapter 2 then gives you the steel platform parts including the rollstop cpl., warning flags, and support wheel (Part No. 67646, 93/55 mm diameter). If you need to replace a mounting bracket, you get exact OEM numbers — not a generic “fits all” part.

Cylinders and Valves: Where Mistakes Cost Time and Money

Chapter 3 is critical. Here you have the lift cylinder (67576, D=80 mm, Lh=1350) and tilt cylinder (69813, D=90 mm). These are hydraulic components that must match exactly — bore, stroke, ports. The catalog also includes the piston seals and bushing assemblies. Then Chapter 6.2 jumps to the valve system (31856, 24 volt). Mixing up a valve spool or coil can shut down your entire rig. This catalog gives you the exact part number for the valve block, solenoids, and associated hardware.

Why a 2009 Parts Catalog Beats a Generic Diagram

I’ve seen aftermarket diagrams that claim to cover “most HIAB models.” They don’t show the serial number breaks or the specific revision of the electric safety valve. This catalog has three sub-chapters for the electric safety valve (68155, 68155a, 68155b) based on serial number ranges: up to 136672, 136673–139046, and 139047 onward. That level of detail keeps you from ordering a valve that doesn’t fit your control system. For background on hydraulic systems, see the Automotive Industry Overview. Automotive Industry Overview is another resource worth checking if you’re new to mobile hydraulics.

Hydraulic Unit and Valve System: 24 Volt, 170 Bar Specs

Chapter 6 lists the hydraulic unit (68116, 6000, 24 volt, 170 bar). That’s your power source. The valve system in Chapter 6.2 is 24 volt and includes the pressure relief and directional control valves. Page 14 gives you the complete unit breakdown — filter, pump, motor. If you’re troubleshooting a dead lift, this chapter tells you exactly which seal kit or valve cartridge to order. No need to disassemble twice.

Electric Safety Valve: Three Serial Number Ranges

Chapter 7 splits into three sections based on your machine’s serial number. The electric safety valve is a critical safety component — it locks the boom if hydraulics fail. Using the wrong revision can bypass that safety function. The catalog lists each valve with its own part number: 68155 for early units, 68155a for mid-production, and 68155b for the latest. Check your plate and order accordingly.

Questions You Might Have About This Catalog

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. You get part numbers and quantities only.

Will this work for my BZZ 250-135 built after 2009?

This 2009 edition covers machines up to that year. HIAB often revises part numbers for later serial numbers. The catalog includes three serial number breaks for the electric safety valve, which suggests later updates exist. If your unit has a serial number above 139047, verify with HIAB that the valve (68155b) is still current. For the lift chassis and cylinders, I’ve seen these parts run for years with minor changes — but always confirm using your machine’s VIN or serial plate.

Can I use this catalog to rebuild a cylinder?

You get the part numbers for the cylinder assembly, seals, and bushings. Rebuild procedures (disassembly, honing, torque specs) are not included. You’ll need the service manual for that.

How do I find my serial number?

Look on the chassis plate near the lift arm. It’s a stamped metal tag. The serial number is usually a 6-digit number starting with 1 or 2.

If you’re working on a HIAB BZZ 250-135 and need the right parts the first time, this is the catalog to use. No guesswork. Access the Factory Manual now and keep your lift running.
