Operator Station:
Open operator station with a seat, steering wheel, and controls. Seat belts may not have been standard on early models.
Engine Oil Change:
Recommended every 50-75 operating hours or annually. Consult the manual for specific IH oil recommendations.
Transmission Oil Change:
Typically every 200-300 operating hours, depending on usage severity.
Greasing:
Regular greasing of all grease fittings (pivot points, U-joints, etc.) every 10-25 operating hours.
Engine Oil Grade:
Likely SAE 30 or 10W-30 API CD/SE rated oil. Specific viscosity depends on ambient temperature. Refer to manual for exact IH specifications.
Transmission Hydraulic Fluid:
Likely a Type A Suffix A Automatic Transmission Fluid (ATF) or an equivalent hydraulic fluid. Check manual for exact IH specification and capacity.
Coolant:
For gasoline engines, a mixture of permanent antifreeze and water (50/50) is typical. Capacity depends on radiator size.
Carburetor Problems:
Vintage carburetors can be prone to gumming up, leading to rough running or starting issues if not properly maintained or if stale fuel is used.
