Engine Overview
Operators of W14 loaders fitted with the 336 engine often praise its reliability and adequate power for forestry loading tasks. One operator shared a story of extending the engine life beyond 10,000 hours with diligent maintenance including timely oil changes and use of quality lubricants. Another shared the challenge of sourcing remanufactured engines but emphasized that direct OEM replacements guaranteed performance and parts compatibility.
Terminology
The Case W14 loader’s engine replacement with the original 336 diesel engine or equivalent ensures optimal performance for demanding forestry and loading tasks. Understanding engine specs and ensuring proper installation and maintenance guarantees the longevity and efficiency of this classic loader model. The Case 336 engine remains a workhorse power unit balancing power and reliability in mid-sized industrial machines.
- The Case W14 loader is powered by the Case 336 cubic inch (5.5 liter) diesel engine.
- It is a 4-cylinder, 4-stroke, liquid-cooled engine with a bore and stroke of 4.625 inches x 5.00 inches (117 mm x 127 mm).
- Gross horsepower is rated at 93 hp (69.4 kW) at 2200 rpm.
- Net horsepower is approximately 83 hp (61.9 kW) at 2200 rpm.
- Maximum torque is around 236 lb-ft (320 Nm) at 1550 rpm.
- The engine uses a dry air cleaner and electric starter with 24 volts.
- Oil capacity is about 11.4 liters (12 quarts), and coolant capacity is about 26.5 liters (28 quarts).
- Equipped with a full powershift transmission featuring four speeds for versatile operation and ease of control.
- Loader hydraulic system pressure is approximately 2200 psi (15168 kPa).
- Bucket capacity varies with specifications but typically around 1.1 to 1.2 cubic yards (about 0.96 m³).
- Operating weight and precise dimensions vary with configuration but are designed for strong, steady performance in log and lumber loading applications.
- The Case 336 engine is integral to the W14 loader’s performance. Replacement engines must match specifications precisely to maintain machine balance and performance.
- When replacing the engine, attention must be paid to proper mounting alignment, cooling system reconnection, and electrical wiring integration.
- Regular maintenance of cooling and lubrication systems extends engine life and prevents premature failure.
- Follow scheduled maintenance for oil changes, filter replacements, and coolant system checks to ensure engine reliability.
- Inspect starter motor and electrical systems regularly due to 24-volt starting requirements.
- Maintain air cleaner integrity to prevent dust and debris intake common in forestry operations.
