Expert Maintenance Tip:

For the CAT E200B series, the SPK10/10 pump relies heavily on proper lubrication during startup. Crucial: You must fill the pump case with clean hydraulic oil through the highest drain port before starting the engine. Running the pump "dry" will cause immediate bearing failure. Additionally, if the previous pump suffered a mechanical break, you must flush the hydraulic tank and lines and replace all filters to prevent debris from damaging the new unit.
