Parts Identification:
Primary function is the identification and listing of all replaceable parts for the Kubota L2550DT tractor, with corresponding illustrations and part numbers.
Assembly Disassembly:
Provides detailed illustrations of how components and systems are assembled and disassembled, crucial for part replacement and repair.
Component Level Analysis:
Breaks down major systems into their individual component parts, allowing for precise identification of needed spares.
Optional Equipment Identification:
Illustrates and lists parts for optional equipment such as double air cleaner, under muffler, orchard kit, auxiliary control valves, and swinging drawbar.
Depth:
High. This is a master parts manual, offering a highly detailed breakdown of every component. While not a repair manual, it provides the foundational knowledge of part relationships and assembly crucial for repairs.
Fluid Checks:
While this is a parts manual, it implies the need for regular checks of engine oil, coolant, hydraulic fluid, and transmission/differential oil, for which parts are listed.
Engine Oil Type:
Specific SAE viscosity grade (e.g., 10W-30 or 15W-40) would be detailed in a service or owner's manual, but oil filters are listed.
Hydraulic Fluid:
Kubota UDT (Universal Tractor Transmission Oil) or a compatible fluid is typically used. Hydraulic filters and lines are covered.
Wear Items:
Common wear items in tractors of this age include clutch components, PTO clutches, hydraulic seals, and engine seals. The availability of detailed parts for these systems in the manual is a key benefit.
Advantage:
This manual is invaluable for identifying and sourcing replacement parts, including gaskets, seals, bearings, gears, and filters, essential for maintaining the tractor's functionality.
