The Deutz- Fahr Agrostar 6.61 is the biggest model in the range for that year set at 140hp. It is powered by a 6 cylinder Deutz air cooled engine then coupled to a Deutz manual transmission with a hi-low splitter (some would say its very ZF looking)
Reason for Job:
Tractor was suffering from low transmission pressure, also had become noisy and difficult to change gear
Main problems found:
After splitting the tractor we found the transmission lubrication pump had worn to the point of failure
In turn this had caused a number of bearings to fail and chip a couple of teeth of gears
We also found 2 synchronisers had worn out of tolerance which was creating the difficult gear changes
Wash tractor thoroughly
Remove front end then remove transmission
Strip transmission and identify problems
Replace bearings, broken gears and synchronisers
Re-fit gearbox then mate front end on
Then give a hour on dyno to check for leaks at temperature
Finally a 2 hour road test to ensure tractor is working correctly and leak free
