Yanmar GK
Power steering fluid capacity & service interval
Yanmar GK power steering fluid capacity is 7 liters. Service intervals include checks at 10 hours and changes at 50 hours or 300 hours. The data covers 4 configurations.

Additional Notes
- The Yanmar GK's power steering fluid is part of a combined transaxle and hydraulic system, meaning the 7-liter capacity figure covers all three functions within a single shared fluid circuit rather than a dedicated power steering reservoir alone.
- Both the GK160 and GK200 share an identical 7-liter capacity for the transaxle/hydraulic/power steering system, indicating no variation in fluid volume between the two engine configurations across the 2013-2020 model years.
- Under normal use conditions, the fluid check interval is set at every 10 hours of operation, reflecting how frequently the system level and condition are expected to be monitored between full change intervals.
- The normal-use change interval for both the GK160 and GK200 is 300 hours, which represents the standard recurring service cycle for the combined transaxle, hydraulic, and power steering fluid.
- A first-change-only interval of 50 hours applies to both the GK160 and GK200, meaning the initial fluid change occurs significantly earlier than the 300-hour recurring interval, a practice commonly used to remove break-in contaminants from new mechanical components.
- The first-change-only specification carries no check interval, only a 50-hour change point, distinguishing it from the normal-use schedule where a 10-hour check interval accompanies the 300-hour change cycle.
