Hyster S6.0FT, S7.0FT, S135FT, S155FT 2013 Repair Manual

I’ve repaired dozens of Hyster drive axles over the years. When you’re staring at a wet brake assembly off an S6.0FT or S135FT, you don’t want instructions written by someone who’s never held a torque wrench. This 2013 Repair Manual for the Hyster S6.0FT, S7.0FT, S135FT, S155FT is the factory document – 90 pages of procedures that start with disassembly and end with torque values you can rely on. No aftermarket guessing.

Planetary Reduction Gear Repair Steps

The manual walks you through removing the planetary reduction gear, then cleaning and inspecting every spline, bearing, and seal. Page 15 shows the clean-and-inspect checklist – don’t skip it. A worn needle bearing here can lock up the wheel end. The spec says check for cracks in the carrier. That’s the kind of detail you get when the document was written by engineers who designed the part, not a copy shop.

Does This Manual Cover the Brake System?

Yes – and it’s the wet brake section that makes this manual worth having. Brake Repair starts on page 22 with remove and disassemble, then clean and inspect, then assemble and install. The manual tells you to use HYSTER APPROVED parts, and it lists the seal kit numbers. If you’ve ever had a brake piston hang up because the wrong o-ring was used, you’ll appreciate that. For deeper brake system coverage, check the Hyster Brake System Service Manual 1800 SRM 1247.

Torque Specs on Page 83

Torque specifications are listed on page 83. Every fastener in the drive axle assembly – from the bevel pinion nut to the differential case bolts – has a factory ft-lb value. I’ve seen a shop try to reuse a torque-to-yield bolt on a differential carrier because they didn’t have the spec. That repair came back on a flatbed. This manual gives you the numbers, and it tells you when to use Loctite or thread sealer. That’s not something a generic PDF will do.

3 Major Sections to Know Before You Start

Differential repair is the heart of this manual – pages 40 through 57 cover remove, disassemble, clean, inspect, assemble, and install. The bevel pinion section (page 61) is just as thorough. Drive Axle Installation starts on page 75 and includes shimming procedures. You also get a special tools list on page 82 – don’t try to do the pinion depth without the right gauge. If you’re working on a similar model, the Hyster Service Manual 8000 SRM 1409 might also be relevant.

Use the Torque Specs – Don’t Guess

Even if you’ve done a hundred differential rebuilds, the spec for the S155FT bevel pinion nut may be different from the S6.0FT. This manual covers all four models – S6.0FT, S7.0FT, S135FT, S155FT – with distinct values where they differ. The safety precautions on page 2 are not boilerplate; they call out the risk of battery disconnect on electric models and proper blocking procedures. Read them. I’ve seen a lift truck fall off blocks because someone didn’t follow the manual.

Differential Repair: Factory Sequence

Disassembly steps are numbered. Clean and inspect gets its own subheading. The manual expects you to have a dial indicator and a press. If you don’t, the special tools list tells you what to buy. This is not a book for beginners who want to “feel” their way through a repair. It’s for people who want the repair done right once. For general transmission knowledge, you can reference Manual Transmission basics, but for Hyster-specific assembly, stick to this manual. Another good resource is Manual Transmission theory – different context but same principle of proper disassembly order.

Frequently Asked Questions

Is this manual for the S6.0FT and S7.0FT only?

It covers S6.0FT, S7.0FT, S135FT, and S155FT. All four models.

How many pages is it?

90 pages.

Are torque specifications included?

Yes – page 83 lists every torque value for the drive axle, differential, bevel pinion, and brake assemblies. These are factory numbers from Hyster, not guesses. Missing torque by 10% on a differential ring gear bolt can cause a catastrophic failure. The axle shaft nut is 500 ft-lb; the brake piston housing bolts are 35 ft-lb. You don’t want to estimate that. The manual also specifies when to use Loctite and thread sealant, which is something many aftermarket documents skip. I’ve seen too many shops skip this step and pay for it later.

Is this an OEM or aftermarket manual?

This is a genuine Hyster factory repair manual, published in 2013. Part number 1652523. The scan is from the original SRM 1318 document. No third-party edits.

If you need to rebuild a drive axle on any of these Hyster models, get the document that the factory techs use. Access the Factory Manual and keep it on your tablet next to the bench. Your torque wrench will thank you.
