The fluids used in Hydro-Gear products have
been carefully selected, and only equivalent, or
better products should be substituted.
Typically, an engine oil with a minimum rating
of 55 SUS at 212°F (100° C) and an API classification
of SL is recommended. A 20W-50 engine
oil has been selected for use by the factory
and is recommended for normal operating
temperatures.
FLUID CHANGE PROCEDURE
This transaxle is factory filled, sealed and does
not require oil maintenance. However, in the
event of oil contamination or degradation, oil
addition or change may alleviate certain performance
problems.
1. Remove the transaxle from the vehicle.
2. Clean the expansion tank and oil fill port
areas of any debris.
3. Remove the oil fill port fitting.
4. Position the transaxle so the oil will drain
completely out of the housing.
5. After all the oil is drained from the transaxle,
remove the expansion tank by removing the
self tapping bolt (10-32 x ½) that holds the
tank support bracket.
6. Remove the tank and drain the oil from the
tank. DO NOT remove the vent cap from the
tank. DO NOT remove the tank hose or
o-ring unless a replacement is needed.
7. Install the tank by first inserting the hose
into the opening in the expansion tank.
Push the tank opening over the o-ring to ensure
a proper seal.
