The Massey Ferguson 8947 service manual PDF takes the 8947 telehandler apart system by system across 668 pages, from the lift, extension, tilt and steering cylinders through the hydrostatic drive motor, both axles and differentials, the boom assembly, engine and HVAC. Wiring diagrams and an error code listing cover the electrical system, while troubleshooting charts, torque tables and a service schedule support your routine and repair work. Axle oil checks and drains cover each differential and planetary carrier. Charge the A/C system with 1.76 lbs (0,800 Kg) of refrigerant, then tighten the compressor hoses to 22 ft.-lbs. (29,8 Nm). When your job is tracing the battery and alternator circuits or the 50 A switched power fuse, the wiring diagrams show how those connections run. Bookmarks jump you to each chapter, the text layer takes keyword searches, and the pages print cleanly as a working copy you can mark up.

Massey Ferguson 8947 Common Problems This Manual Covers
Massey Ferguson 8947 telehandler boom goes up slowly at full engine RPM with sluggish hydraulic action
Check the hydraulic fluid level, then confirm the oil is warm and the correct viscosity; page 58 lists cold or wrong fluid as a cause. Inspect the inlet side of the hydraulic pump for a suction leak, using cardboard or wood and safety goggles, never your bare hand (page 35). Confirm the load is within rated capacity. If all pass, suspect pump damage or an internal lift cylinder leak.
Manual Section: Hydraulic System Troubleshooting p. 58Boom creeps down on its own with the hydraulic control lever in the neutral position
Install an approved boom stop before working under a raised boom; page 1 forbids going under it otherwise. Inspect the cylinders for external leaks with cardboard or wood and goggles, never your hand (page 35). If they are dry, suspect an internal lift cylinder leak, then a damaged lift spool, per page 58. Torque the lift cylinder bolt to 255 ft.-lbs. (345 Nm) at installation (page 63).
Manual Section: Hydraulic System Troubleshooting p. 58Hydrostatic system overheating and the warning light comes ON while the telehandler is traveling
Check the hydrostatic fluid level and confirm the operator is running the machine at the correct RPM, per page 289. Inspect the oil cooler for a restriction. If the temperature still climbs, test the temperature sending switch and sender, and check for a plugged hydraulic filter. Suspect a worn or defective hydrostatic pump last.
Manual Section: Hydrostatic System Troubleshooting p. 289Starter will not turn the engine when the ignition key switch is turned to start
Clean and tighten the battery connections, then check the ground connection for good contact, per page 565. Check the fuses and inspect the wiring and solenoid for damage. Test the battery against the 12 Volt, 900 CCA @ 0° F (-18° C) rating on page 651. Wear goggles, protective clothing and rubber gloves around battery acid (page 569). If all test good, suspect a damaged starter or locked engine.
Manual Section: Electrical System Troubleshooting p. 565Alternator will not charge and the battery will not take a charge
Inspect the alternator belt for looseness or damage with the engine stopped (page 49); page 565 lists it first. Clean and tighten dirty or loose battery connections and confirm the ground connection makes good contact. Check the battery for damage, wearing goggles, protective clothing and rubber gloves (page 569). If belt and connections are good, suspect a damaged alternator, rated 12-Volt, 100 amp on page 651.
Manual Section: Electrical System Troubleshooting p. 565With the blower fan switch in first position, A/C compressor clutch does not click or engage
Check the fuse and replace it if blown, per page 608. Unplug the compressor connector and measure clutch resistance with a multimeter; no reading means replace the compressor clutch (page 609). Check for 12 volts at the pressure switch harness with key in RUN, engine off; no voltage means broken wires. Set clutch clearance to 0.01-0.02 in. (0.3-0.6 mm) per page 631.
Manual Section: Air Conditioning Basic Troubleshooting p. 608Frequently Asked Questions
What are the recommended service intervals for the Massey Ferguson Telehandler?
The service schedule requires maintenance at daily, 50, 100, 250, 500, and 1000-hour intervals. For example, engine oil and filter replacement is required at 500 hours, while hydraulic fluid and filter replacement is also required at 1000 hours. p. 25
What are the fluid capacities for the 8947 model?
The fuel tank capacity is 38.3 gallons (145 L). The hydraulic/hydrostatic system holds 33 gallons (125 L), and the engine cooling system requires 18 quarts (17 L). p. 115
What is the correct wheel nut torque for the Massey Ferguson 8947?
The wheel nuts must be tightened to a torque of 221 ft.-lbs. (300 Nm). p. 43
How do I troubleshoot if the battery will not take a charge?
If the battery will not take a charge, check the alternator belt for looseness or damage, inspect battery connections for dirt or looseness, check if the battery is damaged, ensure the ground connection is making good contact, or check if the alternator is damaged. p. 29
What is the procedure for bleeding the service brake circuit?
Lift and block the machine, ensuring jackstands are used. Loosen the bleed screws and use an assistant to apply the service brake until a continuous stream of clean hydraulic fluid flows without air. Tighten the screws after bleeding. Refer to page 90 for the specific sequence of inside and outside bleed screws. p. 89
Do I get instant access to this Massey Ferguson 8947 Service Manual?
All 668 pages arrive as one searchable PDF at checkout. Read it at the desk, then take the phone out to the machine.
