Diesel fuel injection is the fussiest system on these compact tractors, and this 127-page manual starts there, then widens to the clutch, transmission, front axle, brakes, steering and rotary hoe on eight Bolens / Iseki G-series and TX variants. Engine teardown fills much of this Bolens / Iseki G152, G154, G172, G174, TX1300, TX1300F, TX1500, TX1500F service and repair manual PDF, and a power train diagram traces drive from the universal joint through the bevel pinion to the side gear case. Wiring diagrams let you trace the electrical system wire by wire, and the service data section lists torque values and every part that needs sealing agent. Set nozzle injection start pressure to 1707-1849 PSI (120-130 kg/cm²) and time injection at 25 degrees BTDC. Guess wrong and you pay for a second teardown. Print the bookmarked pages and let them collect grease on the bench while your tractor gets back in the field before the weather turns.
