Hyster S40FT, S50FT, S55FTS, S60FT, S70FT (H187) Lift Trucks Pdf Repair Service Manual

Hyster S40FT, S50FT, S55FTS, S60FT, S70FT (H187) Lift Trucks PDF Repair Service Manual

The Hyster H187 Repair Service Manual covers the S40FT, S50FT, S55FTS, S60FT, and S70FT — five sit-down pneumatic tire forklifts spanning 4,000 lb to 7,000 lb capacity. These machines commonly split their working day between warehouse floors and outdoor yard surfaces, a duty cycle that puts steady wear on pneumatic tyres, brake linings, and transmission direction clutches in a pattern different from either a dedicated indoor or dedicated outdoor machine. The repair procedures in this document reflect that application profile.

One variant needs calling out before any service work starts. The S55FTS carries a short mast — its channel dimensions, roller clearance values, and lift cylinder stroke data are specific to that configuration and do not match the S50FT below it or the S60FT above it in the lineup. Physical similarity makes it easy to pull the wrong reference. This manual isolates the S55FTS mast data clearly so there is no ambiguity on the workshop floor.

Manual Technical Specifications

Systems and Repair Coverage

Complete diagnostic, disassembly, and rebuild procedures across all five H187 variants:

• Engine Overhaul and Fuel System: Cylinder bore and wear measurement, valve clearance per variant, head bolt torque sequence, and cylinder head service — LPG regulator and mixer calibration, petrol carburettor rebuild, and diesel injection pump timing and nozzle testing each covered with separate procedures
• Mast and Hydraulic Lift Circuit: Standard mast roller clearance and channel wear for S40FT through S70FT, S55FTS short mast data documented independently, lift cylinder drift test and seal replacement, tilt cylinder rod seal service, relief valve calibration, load-hold leak test, and pump output pressure and flow testing
• Powershift Transmission and Torque Converter: Stall test interpretation, forward and reverse clutch circuit pressure testing with values per capacity class, clutch pack measurement, transmission disassembly from H187 frame layout, modulation valve inspection, and fault diagnosis for engagement faults and converter temperature conditions
• Drive Axle and Differential: Shaft spline condition, ring and pinion backlash and depth setting, carrier bearing preload, housing crack inspection, hub bearing end-float, and seal replacement — S70FT load tolerances noted where they separate from lighter variants
• Electrical and Safety Interlock Diagnosis: Charging system output test, solenoid coil resistance values, seat switch and directional lever interlock tested as individual components, parking brake circuit continuity, engine sensor test values, and instrument warning circuit tracing
• Steering and Brake Repair: King pin bore measurement, toe-in specification after rebuild, drum wear limit per capacity variant, lining thickness minimum, wheel cylinder inspection, pedal travel adjustment, and cross-axle balance verification
• Pneumatic Tyre Service: Inflation pressure per load rating for each variant, tread depth and sidewall damage assessment, and wheel nut torque after tyre work

Why This Manual Matters for H187 Service

• S55FTS short mast roller clearance and cylinder stroke values are unique to that configuration — neither the S50FT nor S60FT specifications are a safe substitute
• Clutch pressure values are not uniform across the 4,000 to 7,000 lb range — the manual identifies where per-capacity values apply rather than using a single figure for all five variants
• The cylinder drift test lets technicians assess seal condition under working load before pulling the cylinder — reducing unnecessary disassembly on high-cycle machines
• Mixed indoor-outdoor operation accelerates brake lining and tyre wear differently than single-environment use — the brake and tyre procedures here account for that pattern
• Three fuel system configurations covered independently — LPG, petrol, and diesel procedures are not merged or approximated from each other

Frequently Asked Questions

Why does the S55FTS need separate mast specifications?
Its shortened mast structure has different channel dimensions, roller clearance values, and cylinder stroke limits from the standard variants on either side of it in the lineup. Using S50FT or S60FT mast data on an S55FTS produces incorrect clearances — this manual separates the S55FTS mast section clearly to prevent that.

What fuel system variants are covered?
LPG, petrol, and diesel configurations are all covered with independent procedures for each — regulator calibration for LPG, carburettor rebuild for petrol, and injection pump timing with nozzle testing for diesel. Engine mechanical procedures shared across fuel types use a single procedure set.

Do all five variants share the same transmission specifications?
Most transmission procedures are common across the H187 platform, but clutch circuit pressure values are documented per capacity class. The S70FT at 7,000 lb carries different clutch pressure specifications from the S40FT — applying the wrong value to either machine affects engagement performance under load.

Is this the correct manual if my machine plate shows H187?
Yes — this is Hyster's factory workshop documentation for the H187 series. If your machine plate, parts record, or service history references H187 alongside any of the five model names, this is the document that contains the correct procedures and specifications for your machine.
