Excess abrasion of the hole in the
support arm connection block
Replace the support arm block
Main shaft positioning spring failure Replace
Main shaft is not stable and the gear
box cover bolts are loosen
Tighten the bolts
Deformation of shift bar leading to
shift interference
Adjust the shift bar or replace it
Reversing shift failure
Reversing fork abrasion
Readjust the reversing cable or
replace the reversing fork
Reversing cable failure Readjust the cable or replace it

the fork move freely
Reversing gears can not be
resetted
The loosening of reversing shaft
makes the gear be blocked to a
standstill
Tighten the reversing shaft
back bolts
Reversing shaft spring failure Replace the spring

The reversing shaft is loosen
Reversing shaft back bolts of are
loose
Tighten the back bolts
The matching between reversing
shaft and gear box body is too loose Replace
Too loud noise from the
gears
Deformation and bent of the bevel
gear and reversing shaft
Replace
Too much lateral clearance due to
excess abrasion of gears
Replace the gear
The matching between bevel gear ,
reversing shaft and gear box body is too
loose
Replace
