Engine Family:
JI Case 'Duke' series, gasoline and LP Gas variants.
Displacement:
Typically 124 ci (2.0 L) for gasoline models (e.g., VA, VAC) and potentially larger for diesel variants if applicable to the specific 'VA' sub-series covered, though the manual emphasizes gasoline/LP.
Cylinders:
4-cylinder inline
Horsepower Gasoline:
Approx. 28-35 PTO HP (Varies by specific model and year within the VA series).
Torque Gasoline:
Varies, but designed for consistent pulling power at lower RPMs.
Carburetor Types:
Likely Marvel-Schebler or Zenith carburetors, specific models identifiable via part numbers.
Fuel Type:
Gasoline or Liquefied Petroleum Gas (LPG)
Transmission Type:
Constant mesh, sliding gear transmission.
Gear Ratios:
Specific gear ratios are detailed within the manual's component breakdowns for internal transmission parts.
Speed Options:
Typically 4 forward speeds and 1 reverse speed, with some models offering a high-speed option or creeper gear.
Engine Oil Change:
Recommended every 50 operating hours or annually, whichever comes first. Specific oil viscosity to be confirmed in accompanying Operator's/Service Manual.
Grease Points:
Daily or weekly greasing of all lubrication points (wheel bearings, pivot points, linkage) as indicated in the Operator's Manual.
Air Cleaner Service:
Regular cleaning or replacement of air filter elements, frequency dependent on operating environment (dusty conditions require more frequent service).
Engine Oil Type:
API Service Classification CC or CD (for diesel, if applicable to sub-models) or SD/SE (for gasoline). SAE 30 or 10W-30 recommended based on ambient temperature. Check Operator's Manual for precise specification.
Transmission Hydraulic Fluid:
Case IH Hy-Tran UT or equivalent. Capacity approx. 4-5 gallons. Critical for transmission, differential, and hydraulic lift operation.
Coolant:
Ethylene glycol based antifreeze mixture for gasoline engines. Capacity approx. 2-3 gallons. Specific mixture ratio for freeze protection is essential.
Carburetor Performance:
Common issues with older carburetors include gumming, worn jets, and leaking float bowls, requiring rebuild or replacement.
Hydraulic Leaks:
Wear in seals, O-rings, and pump components can lead to reduced hydraulic lift capacity or leaks.
Ignition System Reliability:
Deterioration of spark plug wires, distributor cap, and points can affect engine performance and starting.
Steering Wear:
Worn kingpins, bushings, and tie rod ends can result in excessive play in the steering.
Manufacturer:
J.I. Case Company, a major American manufacturer of agricultural machinery.
Series Introduction:
The VA series, including VAC (light utility, with 'C' for cultivating), VAH (heavy utility), and VAO (overhead valve engine), was introduced in the mid-1940s and produced through the 1950s.
Key Innovations:
The VA series was known for its versatility, affordability, and the introduction of features like the Case Eagle hitch, Power-Adjusted Tread (PAT) rear wheels, and the option of LP gas fuel.
Production Years:
Primarily 1945-1955, with variations and successors in the Case lineup.
