Part of the John Deere Repair Manuals.
You have a 550B or 555B with a slipping powershift, a dragging steering brake, or a track that needs splitting. This John Deere repair manual covers that job from teardown to the pressure test that proves the fix.
Old crawlers punish guesswork. Run the power train tests for the wrong serial number break, or torque a final drive by feel, and you will do the job twice. The book covers the 4-cylinder turbocharged diesel, the powershift transmission and undercarriage. It also covers the dozer, loader, winch, ripper, log arch and both the 9300 and 9550 backhoes.
Repair procedures sit in numbered groups. The diagnostic tables, adjustments and pressure tests are in the 9000-series Operation and Test sections. Check the section contents for the group number and go straight to the page you need.
