Hyster HR45-25, HR45-27, HR45-31, HR45-36L, HR45-40LS, HR45-40S, HR45-45LSX (B227) Forklift Parts Manual
These HR45 reach stackers spend their lives loading and stacking containers in rough yards, ports, and rail terminals, so parts get hammered by dust, twist, and heavy lifts. This parts manual is what I use to match what I’m seeing on the machine to the correct Hyster part callout, especially when options and revisions differ between HR45-25, HR45-27, HR45-31, HR45-36L, HR45-40LS, HR45-40S, and HR45-45LSX. If, for example, I’m tracing a hydraulic leak in the boom circuit or isolating a damaged spreader component, this book lets me positively identify the exact valve body, hose, or bracket before I place an order.
Applications & Use Cases
- Confirm correct components when tearing down boom, spreader, or mast assemblies so you don’t mix up similar-looking pins, shims, or cylinders.
- Cross-check configuration differences between the HR45 variants when you’re swapping parts from another unit or a donor machine.
- Verify superseded or updated parts with the illustrated breakdowns before ordering, reducing returns and downtime.
- Trace hose and harness routing so you can route replacements cleanly and avoid rubbing or pinch points.
- Label and bag parts during overhaul, using the manual’s naming to keep hardware and subassemblies organized for reassembly.
FAQ
Q: Can I use this manual on a tablet in the yard?
A: Yes, it’s practical to keep a digital copy on a tablet or laptop so you can zoom in on diagrams right beside the truck.
Q: Is this useful if I only need one small fitting or sensor?
A: Very much so; you can follow the exploded views to the exact subcomponent and avoid guessing at similar fittings or connectors.
Safety Note
Always lock out, support, and isolate the reach stacker safely before inspecting or matching any parts from this manual.
