Engine Oil Change; Transaxle Fluid Change - Husqvarna MZ 52 Operator's Manual

Engine oil change

NOTE: Change the engine oil when the engine is warm.
Refer to the engine owner's manual for the correct
replacement oil and filter change recommendations.
WARNING! To prevent burns, the engine should be
shut off and allowed to cool slightly so the engine is still
warm but the surrounding surfaces and oil are not.
1. Park on a level surface. Apply park brake.
2. Clean the dirt and debris from the area around the oil fill
cap.
3. Remove the cap/dipstick.
4. Locate the drain hose at the left rear of the engine. Place
an adequately sized container under the end of the drain
hose and remove the oil drain plug.
5. Allow the oil to fully drain from the engine.
6. Replace the drain hose plug and tighten securely.
7. Fill the engine with new oil to the bottom of the fill tube
threads. Check the level with the dipstick.
8. Replace the oil fill cap securely when the oil level is FULL.
9. Refer to the Service Journal for oil checking and changing
intervals.
LUBRICATION

Transaxle Fluid Change

This transaxle is designed with an external filter for ease
of maintenance. To ensure constant fluid quality levels and
longer life, an oil filter change interval of every 200 hours is
recommended.
The following procedure is performed with the transaxles
installed in the mower and the mower on level ground. Apply
the pump release valve for each transaxle and set the park
brake.
1. Remove the three filter guard screws and filter guard.
Clean any loose debris from around the perimeter of the
filter.
2. Place an oil drain pan ((12" or more diameter and 8 qt.
capacity is optimal)) beneath the oil filter. Remove the oil
filter from the transaxle.
3. After the oil has drained, wipe the filter base surface and
apply a film of new oil to the gasket of the replacement
filter.
4. Install the new filter by hand, turning it three-quarters to
one full turn after the filter gasket contacts the filter base
surface.
5. Reinstall the filter guard. Torque screws to
65 in/lbs. each.
6. Repeat steps on the opposite side.
7. Drain old oil filters of all free flowing oil prior to disposal.
Place used oil in appropriate containers and dispose of it
in accordance with laws in your area.
8. Remove the top port plug (see illustration) from the left
side and right side of the transaxles prior to filling with oil.
This will allow the transaxles to vent during oil fill.
9. Remove the cap from the transaxles' expansion tank
located on the vehicle frame.
10. Fill with 20W50 motor oil until oil just appears at the bottom
of each transaxles' top port (approximately 2 quarts per
transaxle, 4 quarts total). Install the top port plug into each
transaxle as the oil level reaches the port.
11. Install and torque the top port plugs to 180 in./lbs.
12. Continue to fill the transaxles through the expansion
tank until the FULL COLD line is reached (this will take
approximately 23 additional ounces).
13. Reinstall the expansion tank cap by hand. Be careful to
not overtighten.
