hi i have a d6r it suddenly stopped moving .so i opened up the transmission case to check and found oil dirty and milky. i changed the oil but still the same problem. then i opened the final drives and saw oil leaking with pressure from the left side .i pulled out the final drive to found brake seals wornout. i changed the seals.checked by starting but leaking from left side didnt stopped and milkiness of oil is not even changing or d6 not moving can any expert help.
hi Today i went below D6 again and opened magnetic screen and changed all the possible /3 orings and fixed it back .to check at least the foaming of oil disappeared. then i checked the oil level . the level was low and filled with more oil. now the dozer started moving slowly only on forward direction i changed the gears in reverse ,in forward ,even in neutral but no change. it was only dragging to forward. can any one suggest what to do next????
hello mate First tell me the Serial Number of the dozer. check the transmission pump First of all maybe u have a worn plate
hi thanks today i will check and c .i will let you know. well yesterday i opened transmission and took ouy main relief valve with all 5modulating valves . washed it thoroughly with degreasser and fixed back (also checked the solonoids with12v battery supply found it working). while fixing i found on the harness for the fourth valve that is responsible for second gear engagement ,was broken then i soldered that wire .after soldring i fixed it back. then tested the dozer no change .then i tried setting main relief valve but no change. what do i do next .
