Micro hydraulic pumps capable of reaching 30,000 RPM were not found in the sources explored. Various companies like HAWE North America, Hydro Leduc, and Antares Engineering Services offer micro hydraulic solutions, however, RPM specifications weren’t available on the examined pages​1​​2​​3​​4​. To find micro hydraulic pumps with such high RPM, specialized vendors or manufacturers may need to be contacted directly.

The number of pistons in an engine can vary depending on the type and size of the engine. Common configurations include 4, 6, or 8 pistons. The specific number is determined by the engine’s design and intended use.

When the shaft speed of a hydraulic pump increases, the flow rate of the hydraulic fluid typically also increases. This has several consequences for the hydraulic system. Firstly, faster fluid flow can result in increased system pressure, possibly pushing the system’s limits and risking damage or failure of components. Secondly, higher flow rates might lead to quicker actuator movements, which could impact the precision and control of operations. Lastly, increased speed can generate more heat, potentially causing the hydraulic fluid to overheat, leading to a reduction in system efficiency and increased wear and tear on components.

Adjusting valves on a hydraulic roller cam is a critical maintenance operation for ensuring optimal engine performance, reducing wear and tear, and achieving the correct valve timing. This procedure is particularly important for hydraulic roller cam setups, as they are designed to operate with a certain preload on the hydraulic lifters. The process usually involves rotating the engine to specific positions, loosening and tightening the rocker arm adjustment nuts, and sometimes using a feeler gauge for precise measurement. Incorrect valve adjustment can lead to poor engine performance, increased noise, and potential mechanical damage. Each engine type and camshaft may have specific procedures for valve adjustment, so it’s crucial to consult the engine’s service manual for detailed instructions and torque specifications. This is a task often performed by experienced mechanics, but DIYers can also undertake it with the proper tools, precautions, and technical guidance

My car has no compression, and I most likely bent the valves. Can I swap out the engine head and be good? Or did the pistons get damaged too? Is there a way of telling without taking the whole engine apart?
