Part of the Kubota Parts Manuals.
This is the Kubota parts catalog for the 1600 and 1600DT compact diesel tractors, supplied as a downloadable PDF. It documents the D950 engine and every major system with exploded diagrams and factory part numbers, so you can identify the exact component you need before you order.
The catalog is organized by assembly: engine, transmission and drivetrain, chassis and body, the two-wheel-drive front axle used on the 1600, the four-wheel-drive front axle on the 1600DT, and the RS1300 rotary implement. Each diagram ties a numbered callout to its part, covering the clutch, shafts, differential, steering, control valve, radiator, and more.
Owners, mechanics, and restorers use it to cross-check part numbers, plan a rebuild, and avoid ordering the wrong bushing, bearing, or seal. It is the reference for keeping an older 1600 or 1600DT running with correct replacement parts.

Kubota 1600, 1600DT Common Problems This Manual Covers
Hard starting from fuel or ignition parts
Diesel no-start and no-shutoff faults often trace to the fuel shutoff solenoid, ignition switch, or corroded wiring. The chassis and body section shows the switch, battery, and fuel filter parts you may need to replace.
Manual Section: Chassis and Body p. 67Weak drive or worn clutch
Loss of pulling power can come from a worn clutch or drivetrain components. The transmission and drivetrain diagrams identify the clutch, shafts, creep unit, and differential parts by number.
Manual Section: Transmission and Drivetrain p. 30Slow or weak hydraulics
Sluggish hydraulic response is often a control valve or oil pressure pipe issue on these older tractors. The chassis and body section documents the control valve and pressure pipe parts for repair.
Manual Section: Chassis and Body p. 67Overheating from cooling parts
Overheating during heavy work usually points to the water pump, thermostat, or cooling components. The engine section lists the water pump, water flange, and related parts by their exact numbers.
Manual Section: Engine p. 5Front-drive axle wear on the 1600DT
The four-wheel-drive front axle develops play in the bevel gears, knuckle arms, and differential over time. The dedicated 1600DT front axle section identifies each drive shaft, bearing, and gear part.
Manual Section: Front Axle (1600DT) p. 97Engine oil leaks and worn seals
Aging engines seep oil from the crankcase, oil pan, and gear case as gaskets and seals harden. The engine section provides the exploded views and part numbers to order the correct replacements.
Manual Section: Engine p. 5Frequently Asked Questions
