HST Pump Rebuild — Komatsu D51-22 (Arkansas)
We recently completed a full rebuild of an HST pump from a Komatsu D51-22 for a customer in Arkansas who reached out to us after multiple repair attempts by other shops failed to resolve the issue.
Our team performed a complete teardown, inspection, and precision rebuild of the pump, addressing the root causes that had been previously overlooked. The unit was restored to proper operating specifications, returned to service — delivering the performance and reliability the customer had been chasing for months.
This project reflects our commitment to solving complex component problems correctly the first time, even when others cannot.
