Takeuchi TR03 excavator now only tracks in a circle.
No track drive on the left hand side.
No visible oil leaking from the track drive motor.
a quick connect of the pressure gauge and all is confirmed - Track Drive motor Down.
Right at the end of this post are two interesting video's detailing Final Drives and Motors.
And so we begin on our adventure.
Check the oil!
You saw right Buddy - not a drop after ten minutes.
After taking off the track and removing the final drive motor we get it into the shed.
Extract the final drive cover by patiently fishing out the lock wire through a tiny hole
drilled in the cover.
Cover off - not looking good!
The first set of planetary gears are badly worn - very sharp edges -
seems a bearing has collapsed as well.
Second set of planetary gears - not looking good here either.
There is a muddy , greasy , paste all over , it's not grease and smells of hydraulic oil.
A picture paint a 1000 words.
Not only has the final drive seal failed - letting out all the good transmission oil -
The pump drive motor has also failed bleeding or leaking into the final drive.
With all the work in the mud - the final drive seal allowed free entrance to all the finer contaminants..
And so we have our special mixture of outstanding grinding paste.
Self destruct darling.
Out of curiosity we stripped the drive down to examine the damage.
Notice how the splines have worn away and the condition of the drive gear.
Better shot of the drive axle and gear.
Only one solution here - replace old boy!
