When a reciprocating mud pump is running roughly, it can indicate several potential issues that need to be solved. Here are some steps to help troubleshoot and potentially solve the problem:   1. The plunger/piston and liner are assembled with too big interference fit value： Solution：Loosen the nuts and decrease the interference fit value；   2. The connection rod bearings are too tightly installed： Solution：Check the clearance and adjust it to right scope；   3. Misaligned assembly between plunger/piston, linking rod and cross-head： Solution：Check and eliminate the misalignment；   4. Some connection parts are loose： Solution：Check and tighten the connection parts；   The above methods are only for reciprocation mud pumps of Elephant brand.
