Wrenching on a Same Diamond 230 or 260? This 604-page workshop manual PDF is the factory service book for both tractors, covering the transmission, braking system, front axle suspension, and full hydraulic circuit. You get a complete electrical section with wiring harnesses, connector layouts, and earthing points, plus hydraulic schematics and error code tables for chasing electronic faults through the SerDiA diagnosis software. Page after page of step-by-step procedures walk you through the air compressor, air conditioning, cab, engine, and front lift. Set the fuel pump drivebelt to 40 Nm, and torque standard M12x1.75 hardware between 66.5 and 73.5 Nm. No more chasing electrical gremlins with a multimeter and a prayer. Bookmarked with a full text layer; search any spec by keyword, jump straight to the section you need, and get back to work.

Same DIAMOND 230, DIAMOND 260 Common Problems This Manual Covers
Same Diamond 230 hydraulic functions weak and noisy, loader and steering response slow after hours of work
Check hydraulic oil level and condition first; milky or dark oil means change it and the hydraulic filter together. Trace the circuit against the hydraulic schematic to isolate which branch is starving. If the pump comes off for inspection, prefill the casing with 1.3 L of oil (page 350) before cranking.
Manual Section: Transmission Hydraulic System p. 350Engine cranks slowly or will not start after winter storage, dash lights dim during cranking
Clean both battery terminals to bright metal and load-test the battery before touching the fuel side. Check cable ends for green corrosion creeping under the insulation, a common failure after storage. If the battery support has to come out for access, rig a hoist first; the assembly weighs 60 kg (132.2 lb.), covered on page 250.
Manual Section: Diamond Ii 230-260 Section 30 p. 250Brake pedal feels soft and spongy, pedal travel increases, tractor pulls to one side when braking
Bleed the brake circuit at both outlets first; trapped air gives you that long, spongy pedal. If the pedal still sinks, pull the master cylinder and check the piston bore against the 23.81 mm spec on page 40. Keep test pressure under the 120 bar maximum rating, and verify the brake light switch adjustment while you are in there.
Manual Section: Braking System Maintenance p. 40Shuttle and powershift changes harsh or delayed, transmission warning shows on the Infocenter intermittently
Check transmission oil level and condition on level ground before blaming electronics; low or burnt oil causes harsh engagement. Connect the EDS tester, pull stored codes, and match them against the error code reference. Reseat suspect harness connectors, and torque any loosened M12 mounting bolts to 66.5 to 73.5 Nm per the chart on page 14.
Manual Section: EDS Diagnostic System p. 14Cab air conditioning blows warm on hot days, compressor cycles on and off rapidly
Clean the condenser core and check belt tension before hooking up gauges; a plugged core mimics a low charge. If rapid cycling continues, recover the system and recharge to the full 1900 g quantity listed on page 265. Add the 210 cm³ compressor oil charge only on a first fill after component replacement, not on a top-up.
Manual Section: Air Conditioning System Maintenance p. 265Frequently Asked Questions
What are the torque specifications for wheel nuts on the SAME Diamond 230/260?
The wheel nuts for the SAME Diamond 230/260 (M22x1.5) must be tightened to 500 Nm ±10% (369 lb.ft. ±10%). It is important to tighten the wheel nuts gradually in a crosswise sequence. p. 318
What do error codes on a SAME Diamond 230/260 mean?
Error codes on the SAME Diamond 230/260 refer to electrical faults in the engine system, such as the cable harness or sensors. For example, code 8112 indicates a (M17) Rack travel sensor fault, while 8600 indicates a CAN-Bus-Error. These codes can be read and cleared using the SERDIA software. p. 127
How do I clear fault codes on a SAME Diamond 230/260?
Fault codes can be cleared using the SERDIA software. In the 'Error memory' menu, select the error location using the mouse and click the 'Clear EM' button to delete the error. p. 126
What is the capacity of the engine cooling system for the SAME Diamond 230/260?
The engine cooling system capacity for the SAME Diamond 230/260 is approximately 34 liters (9 US gallons). p. 256
What is the correct tension for the alternator drivebelt?
The alternator drivebelt should have a static deflection of 400 N immediately after fitting, and 250 ± 5 N under load after 15 minutes of operation. p. 256
