Bolens Iseki TX1300/TX1300F & TX1500/TX1500F Tractor Manual Set, 1978–1981 (P/N 553533-2)

The parts list connects exploded assemblies with parts codes and model-specific quantities. Use it alongside the repair procedures and test data in the service volume; the operator booklet covers everyday operation and routine care.

The service volume also retains comparative TX1000/TX1000F and KE55 family data. The parts volume's model-quantity columns determine application to the four tractors listed above. The operator booklet is expressly limited to safety, operation, and general maintenance; major repairs belong to the service volume.

PDF Navigation and Download Contents

Text search and diagram navigation: Manual body text is not searchable in any of the three files. The service PDF has seven bookmarks for major sections; the parts and operator PDFs have none. Small wiring labels require zooming, particularly in the softer operator-volume diagram.

One ZIP contains three printable PDFs totaling 283 pages. These totals include two parts-list cover pages and one Service Memo page, two preliminary pages in the service volume, and the operator booklet's front cover and storage back page.

Engine Overhaul, Tractor Driveline and Rotary-Hoe Service

The following is a selection of the covered work, rather than a complete contents list. Further topics include X501 ridger and X501-R single-furrower setup.

• Engine overhaul: Cylinder-head and valve work, piston/connecting-rod and crankshaft service, main-bearing replacement, oil-pump inspection, and engine reassembly and adjustment.
• Fuel-system tests: Injection timing, nozzle spray and opening checks, injection-pump leakage checks, governor inspection, and fuel-system air bleeding.
• Chassis and driveline: Step-by-step tractor splitting, clutch and transmission work, PTO and differential service, brake and steering adjustment, and 2WD/4WD front-axle service.
• Hydraulic lift: Lift assembly, control-valve adjustment, and system bleeding, supported by component drawings and the related service and adjustment data.
• Electrical diagnosis: Starting-circuit checks, starter no-load diagnosis, alternator output testing, regulator checks, and glow-system inspection, with wiring and grounding-location drawings.
• Parts identification: Factory exploded views with Ref. No. callouts, parts codes, model-specific quantities, standard parts codes, and separate early/late component applications.
• Rotary hoes: SR1000CD/N, SR1100CD/N, and SR1200CD/N tractor mounting, tilling-blade layouts, shaft removal, power-train and section views, and setup differences.

This set is best suited to experienced owners and technicians who have the lifting, pressing, measuring, and test equipment required for internal engine and drivetrain repair; routine operation and maintenance are handled separately in the operator volume.

Exact Model and Build Identification

TX1300 and TX1500 are the 2-wheel-drive models; TX1300F and TX1500F are the 4-wheel-drive versions. E31 identifies low-lug tires, while E32 identifies turf tires.

The parts catalog assigns KE70-11GF two-cylinder diesel engines to TX1300/TX1300F and KE75-11GF engines to TX1500/TX1500F. Its separate Fig. 7A fuel-supply plate is labeled for KE70-11GE and KE75-11GE engines, making the engine suffix worth checking before fuel-system parts are ordered.

Serial-specific parts: The clutch-housing and pedal plates separate TX1300 through S/N 103150 from 103151 and later; TX1500 through 103882 from 103883 and later; TX1300F through 013253 from 013254 and later; and TX1500F through 007348 from 007349 and later.

Engine listings mark later cylinder-head hardware at engine No. 1300 43399 and higher and 1500 35633 and higher. Piston/ring applications split at 1300-series engine S/N 51000/51001 and 1500-series engine S/N 32790/32791. These breaks link the applicable parts codes to the build rather than relying on the model name alone.

Engine Inspection, Fuel Tests and Cooling Work

Engine chapters document disassembly, inspection, reassembly, and adjustment of the cylinder head and crankcase. Compression standards, correction and usable limits, and engine and cylinder-head section views support the inspection work.

Tools and repair cautions: The manual identifies the MD998130 piston-pin setting tool and ST33210-0 main-bearing installer. KE70 pressed piston pins and KE75 full-floating pins require different handling; using the wrong method can damage the piston or connecting rod.

Incorrect main-bearing orientation or lost oil-hole alignment can obstruct lubrication and damage the bearing and crankshaft.

Fuel-system depth: The injection-pump section view accompanies delivery-valve and plunger leakage tests, nozzle checks, and governor work. The manual specifies that injection-pump disassembly and assembly require high technical skill and suitable facilities.

Cooling-system work: Water-pump construction, cooling-fan and belt inspection, belt-tension adjustment, and radiator removal and installation are covered.

Starting-Circuit and Charging Tests

The starting-circuit checks address battery condition, connections, wiring, grounding, and switches before starter removal. Combined with the no-load test and symptom/cause chart, they support diagnosis of a starting fault before treating the starter itself as defective.

Starter and alternator section views accompany the electrical tests and specifications.

Transmission Layouts and Assembly References

The driveline illustrations show 2WD/4WD power-train layouts, transmission construction, and shift patterns alongside the assembly and adjustment procedures.

Reference sections contain torque charts, stud-bolt and lock-wire lists, sealing-agent locations, and lubrication and capacity data.

Rotary-Hoe Setup and Routine Tractor Care

The rotary-hoe chapter distinguishes side-drive CD and center-drive N units. Blade arrangements cover flat tilling, inside and outside hilling, standard tilling, and applicable extension-rotor setups; a separate mounting note applies to TX1300F tractors through serial 5000.

The operator booklet covers controls, starting and cold-weather use, hydraulic operation, lubrication, routine adjustments, problem-solving charts, three-point-hitch assembly, and storage.

Tractor splitting, raised-implement work, and PTO service require secure support, engine shutdown, and electrical isolation.

A Preview of Valve and Oil-Pump Inspection Data

For the KE70 and KE75 engines, the service data lists intake and exhaust valve clearance as 0.014 in. (0.35 mm) with the engine cold, alongside the valve timing and inspection specifications.

The oil-pump inspection data gives a standard body-to-outer-rotor clearance of 0.15–0.20 mm and a usable limit of 0.30 mm, providing a comparison between the standard clearance range and the wear limit.
