Should you be able to slide the rotor and rollers together easily on a roller vane gerotor?

In the context of a roller vane gerotor, the rotor and rollers are designed to work together in a specific manner. The assembly of these components should not be excessively difficult, but they should also not slide together with ease. This is because the design of the gerotor relies on the precise alignment and interaction of the rotor and rollers to maintain proper clearance and ensure efficient operation under pressure.

When the assembly is too loose, it can lead to insufficient contact or engagement between the rotor and rollers, which affects the efficiency and output of the hydraulic system. It could also result in excessive wear or premature failure of the components due to improper lubrication or increased clearance, inhibiting the optimal functioning of the pump.

Thus, while the assembly process should not be overly challenging, the fit should still be secure and provide the necessary resistance to ensure the parts are working cohesively. Therefore, asserting that the rotor and rollers should be very difficult to assemble accurately reflects the importance of maintaining a proper fit for the effective operation of the hydraulic pump.
