Takeuchi TL26 Track Loader Parts Catalog (P/N PT5-101Z5)

• Machine Coverage: Takeuchi TL26 Track Loader, serial numbers 2620002–2621060. OEM Book No. PT5-101Z5, supplied as a 289-page PDF containing 288 manual pages plus one dealer page.
• Undercarriage: “Track Roller,” “Front Idler,” and “Track Adjuster” exploded views identify individual shafts, bushings, seals, and hardware alongside complete assemblies.
• Hydraulic Components: Parts breakdowns cover piston and gear pumps, travel motors, and control, pilot, and self-level valves. Cylinder listings identify replacement seal kits; hydraulic tank and piping pages detail filters, fittings, and hoses.
• Electrical Parts: “Control Box” and “Electrical” drawings identify instrument panels, wiring harnesses, relays, and switches through serial-dependent parts listings. Battery components are cataloged separately.
• Loader and Cab: Arm pins and bushings, quick attachment mechanisms, and bucket parts are cataloged alongside canopy and heater components. Front-door listings distinguish versions with and without a wiper.
• Engine Components: Separate Isuzu sections cover internal engine parts and overhaul-kit contents, with further breakdowns for fuel-injection equipment, starters, and generators.

This OEM parts manual supports component identification and repair parts ordering. It is suited to mechanics and parts staff who are comfortable matching exploded-view callouts to itemized parts lists. The documentation maps out the main frame, control levers, and pedal linkages across serial-number-dependent variations.

Engine Versions and Serial-Number Coverage

The engine and accessories listing distinguishes three installations:

These engine catalogs extend beyond mounting hardware and accessories. Cylinder heads and blocks, crankshafts, pistons, connecting rods, and valvetrain parts have their own listings. Fuel-system coverage reaches injection-pump, governor, feed-pump, and nozzle components. Cooling and lubrication sections identify water pumps, oil pumps, filters, and related piping.

Production Changes That Affect Parts Selection

Track-roller illustrations divide at S/N 2620710. The later listing includes a revised roller assembly with bearings and different shaft and seal components, making that break relevant when selecting undercarriage repair parts.

Travel-motor groups and main hydraulic piping change at S/N 2620810. “Pump Drive” drawings divide at 2620834, while valve-and-accessory layouts divide at 2620835. These are separate changes; the catalog provides the applicable range for each assembly.

Other configurations include a seat assembly with an integrated switch and a quick attachment change at S/N 2620202. These distinctions help match replacement parts to the equipment actually installed.

Parts Lists, Interchangeability, and Manual Scope

Numbered references connect the drawings to part numbers, descriptions, quantities, serial applicability, and remarks. The numerical index links part numbers back to catalog pages and item numbers. Introductory guidance explains assembly contents, interchangeability codes, and items supplied only as part of a kit or assembly.

This is a parts catalog, not a step-by-step repair manual. Electrical pages show component and harness arrangements rather than wiring schematics. Exploded views do not provide disassembly sequences, hydraulic pressure tests, torque tables, or seal-clearance specifications. For work involving raised loader arms or pressurized hydraulics, use the appropriate service manual and its safety procedures.
