Who Is This Manual For?
If you own or work on an Allis-Chalmers One-Eighty, this manual belongs in your shop. It's especially useful if you've just purchased a used tractor without paperwork, you're performing your own routine maintenance, you need correct service intervals and fluid specs, or you're adjusting the hydraulic lift system or three-point hitch for a specific implement. This is the operator's manual — the same book that shipped with the tractor — so it focuses on safe operation, preventive maintenance, and owner-level adjustments rather than full teardown procedures.
What's Covered Inside
The manual is organized into clear sections so you can find what you need quickly. Here's an overview of the major topics:
Operation & Controls
Covers everything from mounting and dismounting the tractor safely, to gear shifting, engine start-up and shutdown procedures for both the gasoline and diesel engines, fuel tank operation, coasting guidelines, towing, and proper use of the operator's seat and instrument panel. A dedicated section on diesel starting fluid is included for cold-weather operation.
Engine Break-In & Operation
Includes the factory-recommended break-in period procedure, separate starting and stopping sequences for gas and diesel powerplants, and guidance on fuel storage to prevent contamination and degradation.
Hydraulic Lift System & Three-Point Hitch
One of the most detailed sections in the book. Covers lift arm lever operation, position control, remote ram levers, and TRACTION BOOSTER operation. The adjustment procedures go deep: feed-back linkage, high-volume bleed-off, large pump relief valve, lever friction, position control linkage, pressure release, rate-of-lower, torsion bar preload, and both the TRACTION BOOSTER linkage and system relief valve. Three-point hitch coverage includes hitching to Category I and II implements, draft arms, drawbar setup, lift links, sway blocks, upper link / beaming tube, and both hydraulic and mechanical shift procedures.
Scheduled Maintenance & Service Intervals
The manual lays out a clear, interval-based service schedule so nothing gets overlooked:
- Every 10 hours: Check engine oil level, hydraulic oil level, cooling system, front axle, sediment bowl, and three-point hitch.
- Every 50 hours: Inspect batteries, final drive oil level, hydraulic oil and filter, and transmission oil level.
- Every 75 hours (diesel): Change engine oil.
- 100 – 300 hours & every two months: Service distributor points (gas), engine oil and filter (gas), spark plugs (gas), and TRACTION BOOSTER linkage.
- Every 500 hours: Repack front wheel bearings and replace the fuel filter.
- Every 600 hours: Service the air cleaner, distributor points, final drive oil, and hydraulic oil.
- Twice a year: Inspect front support and replace the hydraulic oil filter.
Adjustments
Step-by-step adjustment procedures for the carburetor, fan belt, valve lash, clutch, and brakes — the kind of routine tweaks that keep the tractor responsive season after season.
Air Cleaner Service
A thorough walkthrough of the oil-bath air cleaner system including element inspection, cleaning with compressed air or water, servicing the air cleaner cup, and proper reinstallation of the filter element.
Tires & Weighting
Covers recommended pressures and inflation procedures for 13.6×38 and 15.5×38 rear tires, optional Hydromatic tractor tires, and how to properly weight the tractor for different field conditions.
Electrical
Includes the alternator overview and complete wiring diagrams for both diesel and gasoline models — invaluable for tracing electrical issues or restoring original wiring.
Additional Sections
The manual also covers general safety precautions, recommended lubricants and fuels for both gas and diesel engines, a consolidated service chart, tractor storage procedures, troubleshooting tips, power take-off operation, and parts ordering information.
