500 Hour Service Interval Guide for a John Deere 650K Dozer – Part 6
Written by Luis Montes Updated On April 9, 2025
Part 5 covered changing the final drive oil on the John Deere 650K dozer.
Although not exclusively a part of the 500 hour service for this equipment, this last post will show how to change the hydraulic filters.
On the Tekamo HD YouTube channel, you can watch Keith (an expert heavy equipment mechanic) service the hydraulic oil filters.
The 650K Dozer Has Two Hydraulic Filters
The John Deere 650K hydraulic oil filters are in the right rear service door. The machine features two filters: a hydraulic oil filter and a transmission oil filter.
Plenty of oil will come out when you remove the old filters, so put a catch pan underneath. There’s enough room for a pair of pliers. Turn the filters clockwise to break them loose.
Before installing the new filters, lubricate their seals with a thin oil film. You can use some of the oil dripping from the housing.
The oil film prevents the seal from binding and twisting against the housing as you tighten the filters.
Although the operator’s manual mentions using a wrench to install the filters, we recommend doing it hand-tight, as people tend to overtighten spin-on filters when using tools.
