Hyster S40FT, S50FT, S60FT, S70FT, S55FTS (G187) Forklift Trucks Pdf Repair Service Manual

Hyster S40FT, S50FT, S60FT, S70FT, S55FTS (G187) Forklift Trucks PDF Repair Service Manual

The Hyster G187 Repair Service Manual covers the S40FT, S50FT, S60FT, S70FT, and S55FTS — a group of model names that also appears under the H187 series code. That overlap matters. The G187 and H187 share model designations but represent different production generations with their own hydraulic system configurations, electrical layouts, and component specifications. A technician pulling an H187 procedure to service a G187 machine — or vice versa — is working from the wrong generation document. If your machine's series plate, parts record, or service history shows G187, this is the correct manual.

At 4,000 lb to 7,000 lb capacity on pneumatic tyres, these machines handle distribution center dock work, light manufacturing floor operations, and yard-side material movement — environments where direction change frequency is high and mast cycle counts accumulate quickly. The S55FTS short mast variant sits within this lineup as a configuration specifically built for restricted overhead clearance, carrying channel, roller, and cylinder specifications distinct from the standard variants flanking it.

Manual Technical Specifications

Systems and Repair Coverage

Complete diagnostic, disassembly, and rebuild procedures for all five G187 variants:

• Engine Overhaul and Fuel System: Cylinder bore measurement, piston ring and valve clearance data per variant, head surface and valve seat service, head bolt torque sequence — LPG regulator pressure and mixer calibration, petrol carburettor rebuild and float adjustment, and diesel injection timing and nozzle return testing each documented with independent procedures
• Mast Assembly and Hydraulic Circuit: Channel wear and roller clearance for standard FT variants, S55FTS short mast specifications held in a separate section with its own values, lift cylinder bore and drift assessment, seal kit replacement, tilt rod seal service, relief valve setting, load-hold valve test, and pump flow and pressure output verification
• Powershift Transmission and Torque Converter: Converter stall test and rpm reading interpretation, clutch circuit pressure testing across forward and reverse with per-capacity values, pack disc and plate wear measurement, pack clearance specification, G187 frame-specific transmission removal sequence, valve body spool inspection, and symptom-led fault diagnosis
• Drive Axle and Differential: Shaft removal and spline wear check, ring and pinion mesh geometry setting, carrier preload adjustment, housing weld inspection, hub bearing end-float specification, and seal replacement procedure
• Electrical System and Interlock Diagnosis: Alternator output and starter draw testing, solenoid coil resistance and actuation values, seat switch and directional interlock tested individually at component level, parking brake circuit check, engine sender test values, and gauge and warning lamp circuit diagnosis
• Steering Axle Repair: King pin bore wear limit and replacement procedure, toe-in specification after axle rebuild, and hub bearing preload adjustment
• Brake and Tyre Service: Drum wear limit and lining thickness minimum per capacity variant, wheel cylinder bore inspection and bleed sequence, pedal travel specification, parking brake adjustment, tyre inflation pressure per load rating, and wheel nut torque after tyre work

Why This Manual Matters for G187 Service

• The G187 series code is the critical identifier — same model names appear on the H187 generation, and the two are not interchangeable from a service documentation standpoint
• G187-specific hydraulic layouts and electrical configurations mean component test values and assembly sequences differ from what H187 documentation shows for the same named model
• S55FTS short mast data is held separately from standard variant specifications — it does not share roller clearance values or cylinder stroke limits with the S50FT or S60FT
• Clutch circuit pressure values vary across the capacity range — the manual documents per-class values rather than applying a single figure to all five machines
• High direction-change frequency in dock and distribution environments makes transmission clutch pack condition the most consequential wear area on these machines — the pressure test procedure here identifies deterioration before it becomes a full rebuild

Getting This Manual From Manualskart

Manualskart lists this manual under the G187 series code specifically. Customers searching for S-series documentation who need the G187 generation rather than the H187 will find the correct document here without having to cross-reference series plates against multiple listings.

• Download available immediately after purchase — no processing delay
• Permanent access from a single purchase with no ongoing charges
• Full-text searchable PDF — torque values, circuit references, and part identifiers are all keyword-findable
• Formatted for printing individual sections at workshop scale
• 30-day refund if the series code does not match your machine
• SSL-secured checkout via PayPal or card

Frequently Asked Questions

My machine shows S60FT — how do I know if I need the G187 or H187 manual?
The model name alone does not determine the correct manual — the series code does. Check the data plate on your machine or your service and parts records for the series code. If it shows G187, this is the correct document. If it shows H187, that is a different generation requiring its own publication.

What makes the G187 hydraulic and electrical procedures different from the H187?
The G187 generation carries its own hydraulic circuit configuration, solenoid valve specifications, and electrical layout. Component test values, assembly sequences, and wiring references reflect the G187 build standard — not the H187 revision. Using procedures from the wrong generation produces incorrect results on both systems.

Is the S55FTS short mast section easy to identify within the manual?
Yes. The S55FTS mast data — channel dimensions, roller clearance values, and cylinder stroke specification — is documented in its own section rather than embedded within the standard variant procedures. There is no ambiguity about which values apply to the short mast configuration versus the full-height variants.

What engine fuel types are covered?
LPG, petrol, and diesel configurations are all covered with separate procedures for each fuel system. Engine mechanical overhaul procedures that are common across fuel types are consolidated, while fuel-specific calibration, timing, and adjustment procedures are documented independently for each configuration.
