Hyster Fortis S40FT, S50FT, S60FT, S70FT, S55FTS (F187) 4-Wheel Cushion Tire Lift Trucks Pdf Repair Service Manual

Hyster Fortis S40FT, S50FT, S60FT, S70FT, S55FTS (F187) 4-Wheel Cushion Tire Lift Trucks PDF Repair Service Manual

The Hyster F187 Repair Service Manual covers the Fortis S40FT, S50FT, S60FT, S70FT, and S55FTS in their 4-wheel cushion tire configuration — rated from 4,000 lb to 7,000 lb for indoor industrial use. These model names appear across three series codes — H187, G187, and F187 — each representing a different production generation with its own hydraulic configurations, electrical layouts, and component specifications. The series code on your machine's data plate is the only reliable way to identify which generation document applies. F187 on the plate means this manual. H187 and G187 are separate publications covering different generations of the same named models.

The cushion tire fitment on the F187 Fortis also separates it from the H187 and G187 generations, which are pneumatic tire machines. Cushion tires place these machines firmly in smooth-floor indoor environments — manufacturing plants, cold storage facilities, and warehouse distribution centers — and the tyre removal and pressing procedure applies here where it does not on pneumatic variants carrying the same model names. The S55FTS short mast remains a configuration requiring its own separate specifications within this series.

Manual Technical Specifications

Purchasing From Manualskart

Three series codes — H187, G187, and F187 — share the same model names in the Hyster S-series range. Manualskart lists each generation separately by series code so the correct document reaches the correct machine. Searching F187 returns the F187 Fortis cushion tire generation, not an adjacent series with overlapping model names.

Why This Manual Matters for F187 Service

• Three generations — H187, G187, and F187 — share identical model names but carry different hydraulic configurations and electrical layouts that are not interchangeable across publications
• Cushion tire fitment separates the F187 from the H187 and G187 pneumatic variants — the tyre pressing procedure here applies to this generation specifically and is absent from pneumatic tire S-series documentation
• S55FTS short mast channel dimensions, roller clearance values, and cylinder stroke data are specific to that configuration — neither the S50FT nor S60FT specifications from any generation are a valid substitute
• Clutch circuit pressure values vary across the 4,000 to 7,000 lb capacity range — the manual documents per-class values rather than a single figure applied across all five variants
• High-cycle indoor operation accelerates mast chain wear and lift cylinder seal deterioration — the cylinder drift test procedure here allows condition assessment under working load before disassembly is committed to

Systems and Repair Coverage

Complete diagnostic, disassembly, and rebuild procedures for all five F187 Fortis variants:

• Engine Overhaul and Fuel System: Cylinder bore and wear measurement, valve clearance per variant, cylinder head and valve seat service, head bolt torque sequence — LPG regulator and mixer calibration, petrol carburettor rebuild and float adjustment, and diesel injection pump timing and nozzle return testing documented with independent procedures reflecting F187 engine installation specifics
• Mast and Hydraulic Lift Circuit: Standard mast channel wear and roller clearance for S40FT through S70FT, S55FTS short mast specifications in a dedicated section with its own values, lift cylinder bore condition and drift test, seal replacement, tilt rod seal service, main relief valve calibration, load-hold valve leak test, and pump output pressure and flow verification
• Powershift Transmission and Torque Converter: Stall test and rpm interpretation, forward and reverse clutch circuit pressure testing with per-capacity values, pack disc and plate wear measurement, transmission disassembly from F187 Fortis chassis layout, modulation valve spool inspection, and symptom-based fault diagnosis for engagement faults and converter temperature conditions
• Drive Axle and Differential: Shaft spline condition check, ring and pinion backlash and mesh geometry setting, carrier bearing preload, housing weld stress inspection, hub bearing end-float, and seal replacement — S70FT load tolerances identified where they separate from the lighter variants
• Electrical System and Safety Interlock Diagnosis: Alternator output and starter draw testing, solenoid coil resistance values per F187 specification, seat switch and directional lever interlock tested as individual components, parking brake circuit continuity check, engine sender test values, and instrument and warning circuit fault tracing
• Cushion Tyre, Steering, and Brake Repair: Cushion tyre removal and pressing procedure with F187 rim specification and post-press seating inspection, king pin bore wear limit and toe-in specification after rebuild, service brake drum wear limit and lining minimum per capacity variant, wheel cylinder inspection, pedal travel adjustment, and parking brake holding force test

Frequently Asked Questions

My machine shows S60FT — there are three series codes with this model name. How do I pick the right manual?
The series code on your machine's data plate is the only reliable identifier — not the model name. H187 covers one generation, G187 a second, and F187 this Fortis cushion tire generation. Each carries different hydraulic circuit configurations and electrical specifications. Check the plate before purchasing any S-series manual.

What makes the F187 cushion tire procedures different from the H187 and G187 pneumatic variants?
The cushion tyre removal and pressing procedure is specific to cushion tire machines and does not appear in the H187 or G187 pneumatic documentation. Rim specifications, tyre seating depth, and post-press inspection criteria all reflect the cushion tire configuration. Additionally, F187 component test values and assembly sequences reflect this generation's build standard.

Is the S55FTS short mast section clearly separated from the standard variants?
Yes. The S55FTS mast data — channel dimensions, roller clearances, and cylinder stroke limits — is held in its own section rather than embedded within standard variant procedures. There is no ambiguity about which values apply to the short mast configuration.

What fuel system types does this manual cover?
LPG, petrol, and diesel configurations are all covered with fully independent fuel system procedures for each. Calibration data reflects the F187 Fortis engine installation — not carried over from H187, G187, or any other related series.
