Check Fluid Level on Hydrostatic Transmission
• After THROUGHLY cleaning the outside of the case
near the expansion tank, and the chassis. Carefully
remove the expansion tank.
• Insert the scale through the expansion tank opening
until it stops, at about 5-5/8" (142.8 mm).
• The oil level should be between 3-5/8" and 4-3/8"
(92.07 mm and 111.27 mm). (2.0" to 2.75" [64.69
mm - 69.85 mm] if measured from the top of
casting.)
NOTES
If low add ONLY Tecumseh's hydraulic oil part
#730228A.
New Hydrostatic Transmission replacement units come
with oil. It is a good practice to check the level before
installing. DO NOT OVERFILL.
We do not recommend checking the fluid level of the
Hydrostatic Transmission unless there is a specific
problem that may be caused by the fluid level. Any
contaminants that get into the Hydrostatic Transmission
can destroy it in a short time.
4-3/8" (111.12 mm)
