CHANGING HYDROSTATIC TRANSMISSION AND HYDRAULIC SYSTEM OIL FILTERS
NOTE: Except for the initial
Initial Break-In Period Filter Change
During the initial hours of tractor operation, contam- inants caused by the normal
Hydro Pump Filter — Part No.
NOTE: A large volume of oil may drain from the transmission while performing the 25 hour change of the oil filters. If collected in a clean container and kept free of debris, this oil may be reused in the transmission/ hydraulic system.
Perform the INITIAL change of the transmission and hydraulic system oil filters as follows:
•Remove any belly mounted attachments.
•Clean the areas around the hydrostatic trans- mission and hydraulic system oil filters. Refer to Figure 43.
•Position a CLEAN, suitable container below the hydrostatic transmission filter. See Figure 43.
•Apply a light coating of clean transmission oil to the gasket of the new hydrostatic filter.
•Remove the old hydrostatic filter by turning it counterclockwise, and immediately replace with the new filter. Turn the filter clockwise, by hand, until the gasket contacts the filter base on the transmission housing; then tighten the filter an additional 1/2 to 3/4 turn.
•Position the collection container below the hydraulic system filter. See Figure 43.
•Apply a light coating of clean transmission oil to the gasket of the new hydraulic system filter.
•Remove the old hydraulic system filter by turn- ing it counterclockwise, and immediately re- place with the new filter. Turn the filter clock- wise, by hand, until the gasket contacts the filter base on the transmission housing; then tighten the filter an additional 1/2 to 3/4 turn.
•Clean the area around the transmission oil fill plug/dipstick to prevent debris from entering the transmission (Refer to Figure 42) and remove the plug.
•Following the instructions previously provided in CHANGING TRANSMISSION/HYDRAULIC SYSTEM OIL, refill the transmission with the clean salvaged oil or with new hydraulic oil.
•Reinsert the oil fill plug/dipstick into the trans- mission housing and turn clockwise until tight.
•Start the engine and allow it to run for a few minutes. Shut the engine off, then check for leaks and recheck the oil level in the transmis- sion housing.
NOTE: If a front end loader and backhoe are in- stalled on the tractor after the first 25 hours of operation, it is recommended that the filters again be changed after the first 25 hours of operation with these attachments installed.
Regularly Scheduled Oil Filter Changes
Change the hydrostatic transmission and hydraulic system oil filters along with the hydrostatic trans- mission/hydraulic system oil after every 200 hours of operation. Refer to the previous
CHANGING TRANSMISSION / HYDRAULIC SYS- TEM OIL and follow the instructions for changing the oil and filters.
