Abstract
The present invention relates to a grease replacement method of replacing grease in a case (84) including a sealable gear chamber (31, 36) accommodating a gear (85) as a member to be lubricated, a grease injection port (61, 62) configured to inject grease into the gear chamber (31, 36), and a discharge port (32, 37) configured to discharge the grease in the gear chamber (31, 36), and a grease suction device to be used to perform this method. The grease replacement method includes a suction step (S2) of sucking the grease in the gear chamber (31, 36) from the grease injection port (61, 62) with the discharge port (32, 37) being open, and discharging the grease outside the case (84), and an injection step (S4) of injecting new grease into the grease injection port (61, 62) and supplying the new grease to the gear (85). This facilitates discharging of old grease.
