Rebuilding a boom, splitting an axle or tracing a dead circuit goes quicker with 670 pages of factory procedure behind you, and this Massey Ferguson 8925, 8926 service manual PDF (OEM ID 8925/26) puts them in one file for both telescopic handler models. The hydraulic system takes the largest share of the book, covering the lift, extension and bucket positioning cylinders, while the hydrostatic drive, axles, boom, engine and HVAC each get a chapter. Wiring diagrams back up the electrical analysis section, and a fault code listing plus machine torque tables keep reassembly honest. Set the pump coupler gap to 0.0625 inch (1,59 mm), then check that the shaft turns at 4 to 9 ft.-lbs. (5,4 to 12,2 Nm) after break away. Resealing an extension cylinder is slow enough without hunting specs. Bookmarked and text searchable, the file rides on your laptop to whichever yard your 8925 or 8926 is working in.

Massey Ferguson 8925, 8926 Common Problems This Manual Covers
Massey Ferguson 8925 8926 telehandler hydraulic boom slow, action not smooth, and boom drifting down
Check hydraulic oil temperature and overall system operation first, then work through the slow action, non-smooth action, boom speed and boom drift checks in the troubleshooting chart. Verify the main relief valve setting on page 161 is 3843 PSI (265 Bar) before pulling the lift, extension or bucket positioning cylinder.
Manual Section: Hydraulic System TroubleshootingTelehandler hydrostatic drive overheating with warning lights on and machine not tracking in a straight line
Check which warning light is on and whether the overheating shows up with poor straight line travel. Then run the hydrostatic troubleshooting chart for machine movement, overheating and warning lights. Inspect the hydrostatic pump and hydrostatic drive motor last, using the Hydrostatic System section that begins on page 241.
Manual Section: Hydrostatic System TroubleshootingHydrostatic pump coupler gap set wrong or pump shaft turning too stiff after pump installation
Measure the coupler gap during pump installation and set it to 0.0625 inch (1,59 mm) as shown on page 315. Test the torque needed to turn the pump shaft: after break away it should fall between 4 ft.-lbs. (5,4 Nm) and 9 ft.-lbs. (12,2 Nm). If it reads outside that range, recheck the installation before startup.
Manual Section: Hydrostatic System p. 315Front or rear axle differential leaking oil with bearing wear, shaft spline wear, or a broken half shaft
Check the axle oil level, then drain the oil following the axle procedures in Safety Maintenance. Inspect the pinion and ring gear for damage, the bearings for wear and the shaft splines for wear, using the drive system troubleshooting chart and the front and rear axle and differential procedures in the Drive System section starting on page 317.
Manual Section: Drive System p. 317Battery not charging, alternator charging fault, or starter not operating on the telehandler
Test the battery first and get it fully charged before you chase anything else. Then check alternator charging and starter operation using the electrical troubleshooting charts. Follow the battery maintenance and electrical wiring safety steps on page 6 before you disconnect any cables, and work from the Electrical System section starting on page 511.
Manual Section: Electrical System & Analysis p. 511Cab air conditioning cooling poorly with blower motor or compressor not operating
Check blower motor operation and compressor operation first. Then connect gauges and compare your readings against the gauge pressure diagnostics in the A/C troubleshooting. When you recharge, fill the system with 1.76 lbs (0.800 Kg) of refrigerant as listed on page 628. If you replace the compressor, verify the oil charge at 150 to 170 cc using page 611.
Manual Section: Heating, Ventilation, Air Conditioning p. 595Frequently Asked Questions
What are the torque specifications for the wheel nuts on the Massey Ferguson 8925/8926?
The wheel nuts on the Massey Ferguson 8925/8926 must be tightened to a torque of 221 ft.-lbs. (300 Nm). It is required to check the wheel nut torque every 8 hours for the first 24 hours of operation. p. 21
What is the procedure for releasing the parking brake for towing the machine?
To release the parking brake for towing, turn each of the six screws on the front axle one half turn at a time, repeating until all six are fully in. This requires 4.5 to 5 turns. Ensure you record the number of turns to return them to the same position later. p. 19
What hydraulic/hydrostatic fluid does the Massey Ferguson 8925/8926 use?
Use Massey Ferguson hydraulic/hydrostatic transmission fluid. If it is not available, use 10W-30 or 10W-40 SAE motor oil, or 5W-30 for 0°F (-18°C) and below. p. 667
How do I bleed the service brake system?
To bleed the service brake system, start the engine, lower the restraint bar, and apply the service brake until a continuous stream of clean hydraulic fluid flows from the inside bleed screws. Repeat this process for the outside bleed screws while turning the wheels. p. 59
What is the torque specification for the extension cylinder rod end on the Massey Ferguson 8925/8926?
The extension cylinder rod end bolt must be tightened to a torque of 188-210 ft.-lbs. (255-285 Nm). p. 89
How will I receive this Massey Ferguson 8925 Service Manual?
You get a 670-page searchable PDF that downloads instantly after checkout. Open it on your laptop, tablet, or phone, and bring it right to the shop floor.
Can I print a copy of this Massey Ferguson 8925 Service Manual for the shop?
