Looking for the factory operator guide that fits the whole 1400B family? This 254-page manual (OEM #9801/4494) spans the 1400B Centremount and Sideshift, 1550B, 1600B, 1700B, and Sitemaster. Operating procedures cover cab controls, five distinct backhoe lever-pattern setups, loader work, and road-to-site travel prep, with safety warnings up front. Maintenance covers daily checks through the 2000-hour service, including fluid changes, filter swaps, and greasing charts across every drivetrain. Torque the ROPS/FOPS structure bolts A to 175 lbf ft (237 Nm) and the front wheel nuts to 300 lbf ft (405 Nm), straight from the factory, not a forum thread. When your machine is parked and the clock keeps ticking, skip the generic guesswork. Every section is bookmarked and searchable, so it opens fast on a tablet right at the machine.

JCB 1400B (Centremount) & variants Common Problems This Manual Covers
JCB 1400B and 1700B warning buzzer sounds and the machine loses forward and reverse drive without warning p. 171
Check transmission oil level first; the syncro shuttle transmission holds 20.8 L when full, per the fluid capacities on page 171. If the level is right, make sure the parking brake is fully released before you select a gear, then look at the hydraulic filter condition. Low oil or a clogged filter will set off the buzzer and kill the drive.
Manual Section: Transmission and Axle MaintenanceEngine cranks slowly or won't start, weak or missing charging indication on dashboard p. 155
Inspect the alternator drive belt for correct tension; maximum allowable slack is 3/8 in (10 mm), per the spec on page 155. Clean any corrosion off the battery terminals with a wire brush. If the belt and terminals are sound, test the visible fuses for continuity and confirm the battery holds a charge before calling for service.
Manual Section: Electrical System FaultsHydraulic oil temperature warning light on, loader arms or backhoe moving sluggishly p. 166
Confirm hydraulic fluid level at the sight glass before running the machine any further. The system holds 118 L total; top up to the correct mark with JCB High Performance Hydraulic Oil (ISO VG46) for ambient temps above 38°C (100°F). When you swap the hydraulic filter, tighten the dome nuts to 5 lbf ft (7 Nm) as specified on page 166.
Manual Section: Hydraulic System Diagnostics and MaintenanceParking brake warning light stays on after releasing lever, machine rolls on slope
Verify the parking brake lever has returned to its fully released position before operating. Cross-check the maintenance schedule for the recommended daily brake inspection. Top up the foot brake fluid reservoir if it reads below the MIN mark. Should the warning light stay on once lever position and fluid level both check out, stop work immediately.
Manual Section: Brake System MaintenanceEngine stalls and won't restart, low fuel warning light was flashing before shutdown p. 173
Fill the tank before any restart attempt; total fuel capacity is 90 L, as shown on page 173. If the engine ran dry, you will need to bleed the fuel system to purge air before it fires. While refueling, check engine oil and hydraulic levels too, in case anything else dropped during the run.
Manual Section: Engine Starting and Fuel System TroubleshootingFrequently Asked Questions
What should I check if the JCB 1400B or 1700B warning buzzer sounds and the machine suddenly loses forward and reverse drive?
Check the transmission system as described on page 171. The buzzer combined with drive loss typically indicates a transmission fault that requires inspection of the transmission control system and oil level before moving the machine.
How do I diagnose slow engine cranking or a missing charging indication on the JCB 1400B/1700B dashboard?
Inspect the alternator output and battery condition following the electrical diagnostic procedure on page 155. Confirm belt tension and check the charging system connections.
What steps address the hydraulic oil temperature warning light and sluggish loader or backhoe movement on the JCB 1400B/1700B?
Confirm hydraulic fluid level and condition first, then check for blocked cooler fins or a faulty cooling fan as detailed on page 166. Allow the system to cool before resuming work.
What are the ROPS/FOPS structure bolt torque specifications for the JCB 1400B and 1700B?
Bolts A: 175 lbf ft (237 Nm). Bolts B: 20 lbf ft (27 Nm). Bolts C: 82 lbf ft (110 Nm). All figures are on page 137.
Document Quality
This is a scanned PDF document with an OCR layer, allowing you to search and copy text. The text is generally crisp and readable, though some pages show minor fading or slight blur. Diagrams and illustrations are raster images, mostly clear with readable labels, but they will pixelate if zoomed significantly.
