4. Remove oil filter (7). After you remove the oil filter,
discard the oil filter. The oil filter will contain oil.
5. Clean the housing base for the oil filter. Make sure
that all of the old filter seal has been removed.
6. Apply a thin film of clean oil to the seal of the new oil
filter.
7. Install the new oil filter hand tight until the seal of
the oil filter contacts the base. Note the position of
the index marks on the filter in relation to a fixed
point on the filter base.
Note: There are rotation index marks on the oil filter that
are spaced 90 degrees or 1/4 of a turn away from each
other. When you tighten the oil filter, use the rotation
index marks as a guide.
8. Tighten the oil filter according to the instructions that
are printed on the filter. Use the index marks as a
guide. For non-Caterpillar filters, refer to the
installation instructions that are provided by the
supplier of the filter.
Note: You may need to use a Caterpillar strap wrench,
or another suitable tool, in order to turn the filter to the
amount that is required for final installation. Make sure
that the installation tool does not damage the filter.

Note: Run the machine for at least five minutes in order
to pressurize the hydraulic system.
You should look at oil level gauge (5) in order to check
the level of oil in the hydraulic system. The oil level of
the hydraulic system is correct when the oil level has
reached the line that is marked "MAX" or if the oil level is
halfway between the red line and the blue line on the oil
level gauge. If necessary, add Caterpillar TDTO to the
correct oil level by the following method:
1. Lift latch (6), and loosen hydraulic tank filler cap (7)
slowly in order to relieve the pressure in the
hydraulic system. Remove the hydraulic tank filler
cap.
2. Top up the hydraulic oil to the required level and
install the hydraulic tank filler cap. Clean up any oil
that has spilled. Refer to Operation and
