Hyster H25XM-12, H28XM-16CH, H32XM-16CH, H25XMS-9, H32XMS-9 Service Manual

I’ve been a tech for 28 years and I can tell you the difference between an OEM manual and something printed off a forum. Hyster H25XM-12, H28XM-16CH, H32XM-16CH, H25XMS-9, H32XMS-9 Service Manual is the real deal – direct from the factory. You don’t get 128 pages of fluff. You get the actual procedure for pulling the transmission, rebuilding it, and setting the control valves to factory spec. No guesswork. That’s what pays the bills.

128 Pages of Factory Procedure

This Service Manual runs exactly 128 pages. That’s not filler – it’s every step needed to service the transmission, control valves, and related systems on these Hyster models. Each page was written by the engineers who designed the equipment, not some third-party writer who never held a ratchet. You get the same documentation a dealer tech would use.

Transmission Repair: Remove, Disassemble, Assemble

The manual walks you through removing the transmission, then disassembling each clutch drum – first, reverse, second, third, forward. After that, cleaning and inspecting the housings, oil seals, bearings, gears and shafts. Then assembly in reverse order with exact procedures. Essential for a job where one misstep means oil leaks or clutch slip. Every fastening point is called out with the correct sequence.

Torque Specifications: Grade 5, Grade 8, and Elastic Stop Nuts

You need the right torque for fasteners, and this manual gives you separate tables for Grade 5, Grade 8, and metric grades 8.8, 10.9, 12.9. Plus O-ring port plug torque and pipe plug torque (Table 6 through Table 8). Rely on aftermarket specs and you’ll either strip threads or have bolts back out. These are verified factory numbers – the kind that keep a transmission sealed for years.

Does This Manual Cover the Control Valve Removal?

Yes. The manual includes a full section titled ‘Control Valve Removal and Installation’ and then ‘Control Valve Disassemble and Assemble.’ It breaks down removal of the right and left cover, disassembly of the modulator valve components and regulator valve components, then reassembly. If your H25XM-12 or H28XM-16CH has shift issues, you need this.

Check the Troubleshooting Section Before You Diagnose

Don’t start tearing into the transmission without checking the troubleshooting chart. It covers general symptoms and likely causes. Might save you hours of labor if the problem is in the control valve or a simple adjustment. For basic theory of how a manual transmission works, see Manual Transmission.

Safety Precautions: What Page 2 Tells You

Page 2 lists the safety precautions. Disconnect the battery connector, use correct blocks, wear safety glasses, use Hyster approved parts. This isn’t legal filler – it’s how you avoid getting crushed or electrocuted. The manual uses WARNING and CAUTION symbols with orange and yellow backgrounds. Read it before you start anything.
