HIDALGO-BATISTA, Elio Rafael  and  ROMERO, William. Six Sigma as Strategy of Maintenance in the Corn Harvester Massey Ferguson Model 7252. Rev Cie Téc Agr [online]. 2020, vol.29, n.1  Epub Mar 01, 2020. ISSN 2071-0054.

This article summarizes the results of a research aimed at implementing the Six Sigma methodology as a maintenance strategy in the Massey Ferguson model 7252 combine, and from this implementation, to know the current sigma level of the belt transmission system, a mechanism whose failures, cause low readiness of the system and the machine. The content of the work shows the particularities of the six-sigma method. The results obtained after the implementation have allowed knowing the sigma value of the transmission system between two and three σ, which does not allow transmitting the power with quality, torque and revolutions that the internal combustion engine of the machine offers. The repair cycle for the transmission subsystem, composed of two technical services, was completed. These results are applicable in similar systems, where high levels of operational safety are required.

Keywords : repair cycle; failures; transmission system and root cause.
