Description

FMC B350 Aircraft Tow Tractor Service Manual – Perkins 1004-4T

This is the complete Operation and Maintenance Manual Including Illustrated Parts List for the FMC B350 Aircraft Tow Tractor equipped with the Perkins 1004-4T diesel engine. Published by FMC Corporation/APSD Airline Equipment, Edition 4 (September 1997), Revision 1, this manual applies to tractor serial number 95799 and up. It is the same technical document used in airline ground support operations for the B350 – covering everything from daily operation through component overhaul, with the full illustrated parts list bound in.

The FMC B350 is a turbocharged, four-cylinder diesel tow tractor with a power shift transmission, full-time no-spin four-wheel drive, hydraulically operated two-wheel steering, and hydraulic four-wheel brakes. This service manual covers all of those systems in detail, along with the 24-volt negative-ground electrical system and the aircraft coupler assembly. Whether you are operating the tractor, performing scheduled maintenance, diagnosing a fault, or ordering replacement parts, this is the reference the FMC B350 service manual gives you.

What This FMC B350 Manual Covers

The FMC B350 aircraft tow tractor service manual is organized into six chapters that follow the machine system by system, then provide the parts breakdowns to keep it running.

Chapter 1 – General Information and Operating Instructions

General description of the chassis, axle and wheel assemblies, engine, fuel system, cooling system, air intake and exhaust, transmission, steering, hydraulics, brakes, parking brake, electrical system, and controls and instruments. Operating instructions cover pre-operation checks, normal and cold starting and warm-up, mobile operation, stopping, and shutdown procedures.

Chapter 2 – Maintenance

Routine service on every major system: chassis and body inspection, axles, wheels and tires, engine, fuel system, cooling system, air intake, transmission, drive shaft, steering, hydraulic system, brake system, accumulator servicing, parking brake adjustment, electrical system, and the towing apparatus. Includes troubleshooting tables for axle, engine, engine air intake, engine cooling, engine fuel, transmission, drive shaft, hydraulics (steering), hydraulics (pump), hydraulics (brakes), and electrical faults. Removal and installation procedures for the engine-transmission assembly, transmission, front and rear axles, hydraulic pumps, accumulators, brake valve, steering valve, and steering cylinder are also included, along with hydraulic pump adjustment and accumulator charging.

Chapter 3 – Overhaul

General overhaul guidance pointing to the manufacturer’s data for components or systems that require overhaul, including notes on non-repairable items that should be replaced rather than rebuilt.

Chapter 4 – Illustrated Parts List

Fully illustrated parts listings broken down by assembly. Sections cover ballast, coupler assembly, hood and hatches, dash cover, seats, the engine and transmission installation, engine and transmission mounting, radiator, air cleaner, fuel system (chassis and engine/transmission), fuel tank, exhaust, axle and drive shaft installation, front axle, rear and front drive shafts, park brake (chassis and engine/transmission), tire and wheel installation and assembly, chassis hydraulic installation, hydraulic tank, accumulator, steering assembly, brake valve, engine/transmission hydraulics, accelerator installations, engine/transmission electrical, engine protection system, battery, chassis electrical, gauge cluster, warning light assemblies, main wiring harness, dash panel wiring harness with ignition, shifter relay panel module, shifter electrical, shifter wiring harness, and the final assembly/identification section covering decals, placards, and non-skid.

Chapter 5 – Optional Equipment

Coverage of the optional equipment fitted to B350 tractors, including cab installation, cab ventilation fan, heater/defroster, cab sound insulation, front and rear wiper washers, rear window wiper, rotating amber beacon, turn signal/hazard/high-low beam lights, front coupler work light (spot), rear work light (flood), intercom jacks and cable system, roof-mount 12V radio wiring, tachometer installation, transmission oil temperature gauge, rear coupler mirror, inside rear-view mirror, and emergency stop button electrical.

Chapter 6 – Manufacturer’s Data

Manufacturer’s reference data supporting the overhaul and service work in the earlier chapters.

What This Manual Gives the Technician

This is the reference document behind correct service on a Perkins 1004-4T-powered B350. Torque values, fluid capacities, operating pressures, and adjustment ranges appear throughout the procedures rather than in a separate annex, so the FMC B350 service manual can be worked from directly at the machine. The troubleshooting tables are structured as trouble, probable cause, and remedy, which lets a technician move from a symptom to the correct repair path without guessing at what a fault might be. Because the illustrated parts list is included, the same document is used for parts lookup – the exploded views and itemized tables cross-reference the FMC part numbers and the vendor part numbers where a component is a purchased item.

For the drive train, the manual documents the Rockwell front steering axle (planetary-drive-steer), the rear non-steering planetary-drive axle, and the Funk 2263 power shift transmission with its electronic shifter, downshift inhibit, and parking brake interlock. For the hydraulic side, it covers the closed-center hydraulic system with its pressure-compensated piston pump, in-tank and high-pressure filters, accumulators with dry air pre-charge specification, steering control unit, steering cylinders, and the pedal-operated dual brake valve. For the electrical side, it covers the 24-volt negative-ground system with its dual 12-volt batteries in series, 55-amp alternator, starter motor, sending units, switches, warning light assemblies, and both main and dash panel wiring harnesses.

Systems and Assemblies Documented

The FMC B350 aircraft tow tractor manual treats every system on the tractor as a distinct service subject, so the technician is not left to infer procedures from generic diesel knowledge:

• Perkins 1004-4T turbocharged diesel engine – forced-feed lubrication, fuel/water separator, fuel filter, injector pump, injector timing, valve tip clearance, fan belt tension, and turbocharger service
• Funk 2263 power shift transmission – oil level and pressure checks, filter replacement, drain and refill, shifter control, and torque converter
• Rockwell planetary axles – carrier and planetary lubrication, trunnion bearing service, tie rod ends, king pins, and axle shaft universal joints
• Hydraulic system – pump removal and installation, pressure compensator adjustment, filter replacement, hose routing, tank servicing, and accumulator charging
• Brake system – pedal-operated dual brake valve, wheel cylinders, drum brakes, brake lines, lining wear limits, and bleeding procedure
• Parking brake – lever, cable, caliper, disc pad clearance adjustment, and linkage servicing
• Steering – steering valve, steering column, steering cylinders with ball joint ends, and hose routing
• Electrical – battery, alternator, starter, gauge cluster, warning lights, main harness, dash harness, shifter relay panel, and shifter harness
• Coupler and towing apparatus – two-level coupler with 2-1/2 inch pin diameter, pin weldment, and mounting hardware

Why This Manual Matters for the B350

The B350 is used to maneuver aircraft under a wide range of climatic conditions, and the service procedures in this manual reflect that. Fluid selection changes with ambient temperature, accumulator pre-charge must be verified before certain hydraulic work, the transmission must not be shifted through a complete stop, and the parking brake is designed to hold the tractor rather than to stop it. Getting those details right is what keeps a B350 tractor reliable, and this manual is where those details live in the manufacturer’s own wording.

The illustrated parts list is equally important. Because the manual lists item numbers that cross-reference directly to exploded diagrams, the correct part can be identified from the drawing before an order is placed – whether that part is an FMC-manufactured weldment or a vendor-supplied component identified by Federal Supply Code. For any B350 owner, fleet operator, or shop doing scheduled service, this is the document that ties the whole machine together.
