Casappa hydraulic pump repair

The hydraulic pump of the backhoe loader brand CASAPPA is one of the key components of the hydraulic system, responsible for supplying the required flow and pressure of hydraulic oil. These pumps are usually gear or piston type, with flow capacities ranging from 60 to 120 liters per minute and operating pressures between 180 and 250 bar, providing high efficiency in energy transmission. The precise gear design and optimized sealing system significantly improve performance, reduce leakage, and increase the overall service life of mechanical components.

The main reasons for CASAPPA hydraulic pump failure are oil contamination, cavitation, overload, or high operating temperatures. Early signs of malfunction include pressure drops, unusual noise, and reduced cylinder movement speed. Continued operation with a damaged pump can lead to severe issues in valves and control systems, which drastically increase the overall repair costs. Timely maintenance and oil monitoring are essential to minimize these risks.

Repairing a CASAPPA hydraulic pump typically involves disassembly, inspection of internal wear surfaces, checking seals, and replacing O-rings and bearings. In cases of major damage to gears or pistons, replacement of main components becomes necessary. Repair costs usually ran

New holland combine hydraulic pump repair

The hydraulic pump of a New Holland combine is typically an axial piston type with a swash plate design or, in some models, a vane type with a flow capacity between 90 and 130 liters per minute. This pump can generate an operating pressure range of 220 to 260 bar and is mainly responsible for powering the steering system, cutting cylinders, and feeding mechanisms. Correct pump type selection and monitoring of output flow under heavy working conditions are crucial to prevent efficiency loss and hydraulic oil overheating.

The mounting location of the New Holland combine hydraulic pump is usually on the engine’s side, close to the main gearbox. This placement allows the pump to receive direct mechanical power from the drive shaft, and the connection is commonly made via a flange coupling. At this point, high-pressure lines and return hoses to the hydraulic reservoir are installed, which must be sealed with O-rings designed to withstand pressures up to 250 bar to avoid leakage.

Repairing the New Holland combine hydraulic pump involves disassembling internal components, inspecting pistons, valves, and bearings, and measuring tolerances precisely with a digital micrometer. If wear greater than 0.05 millimeters or cracks in the housing are detected, the affected parts must be re

layland truck clutch disc

The used clutch disc and pressure plate for vintage Leyland trucks are a suitable option for replacing worn components due to their simple design and durable materials. These discs are typically made of hardened steel with diameters ranging from 400 to 420 millimeters, and the clutch plates feature friction linings resistant to heat up to 320°C. The diaphragm springs can withstand torque between 600 and 900 Nm, with an allowable wear gap between disc and plate of less than 2 millimeters. Using tested, quality used components maintains torque transfer accuracy and reduces slippage in medium-duty cycles, restoring approximately 60–70% of the clutch system’s service life compared to new units.

From a performance perspective, used Leyland clutch plates must be installed on the flywheel with proper lubrication and precise alignment to prevent excessive heat and uneven wear. Foreign particles or oil on the friction surface reduce the coefficient of friction and lower clutch efficiency. Depending on age and condition, used components are typically priced between \180 and \300, and with proper inspection for wear and cracks, the cost per 1,000 operating hours is more economical than new aftermarket alternatives.

From an engineering standpoint, Leyland clutch disc and plate des
