The hydraulic system implement pump case drain oil filter is located beneath the cab platform. Open the access door that is directly behind the operator cab.
Remove the hydraulic implement pump case drain oil filter and dispose of the filter properly. Make sure that the old filter seal is removed from the filter base.
Apply a thin coat of oil to the seal on the new filter.
Install a new hydraulic oil filter hand tight until the seal of the 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 hydraulic filter that are spaced 90 degrees or 1/4 of a turn away from each other. When you tighten the filter, use the rotation index marks as a guide.
Tighten the filter according to the instructions that are printed on the filter. Use the index marks as a guide. For non-Cat filters, use the instructions that are provided with the filter.
