Cub Cadet T2-HP - Manual (Page 14)

10 T2 ®
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 per-
formance 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) and ratchet
fastner that holds the tank to the housing .
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 .
8 . Install the tank and self tapping bolt making
sure not to cross thread the bolt . Torque the
bolt to the lower value of the torque speci-
fication listed in the Table on page 15.
9. Fill the transaxle at the oil fill port according
to Figure 3 .
10. Install the oil fill port fitting.
eXpansIOn Tank funCTIOn
The expansion tank allows the T2™ to operate
free of air entrainment and provides maximum
lubrication to the mechanical and hydraulic
components in the transaxle .
As the T2 transaxle is operated, oil in the
transaxle housing heats up which causes the
oil to expand. The oil flows through an internal
hose to the bottom of the vented expansion
tank . As the oil cools, the oil in the transaxle
housing contracts, causing the oil level to go
down in the housing . This creates a nega-
tive pressure in the housing causing the oil
to be drawn back into the case . This keeps
the transaxle housing full of oil at specified
operating temperatures .
