Inspection before removal
Inspection: Total backlash of gears
• “Total backlash of gears” is the gear backlash produced when
the PTO gear, PTO idler gear A, PTO idler gear B and drive gear
are all in mesh with each other.
• Measure the total backlash of gears by inserting a lever type dial
gauge into the threaded holes A in the flange of the PTO head
assembly.
• If the measurement is out of specification, check each gear for
wear and replace if necessary.
• Check the PTO idler gear A, PTO idler gear B and drive gear for
wear. (See TIMING GEARS <WITH FLYWHEEL PTO>.)
