GENERAL INFORMATION

REASON
WAY OF ELIMINATION
The complicated gear shifting
Wrong adjustment of coupling To adjust.
Jamming of draft or cable of the drive To grease or find the reason and to eliminate.
Jamming of a rod of a fork of gear shifting Check fastening of the spherical hinge of the lever, an inhaling of bolts of a cover of the mechanism of management of the check point, wear of rods and openings of rods in a check point case, deformation of epiploons, correctness of installation of back section of a case. If necessary repair.
Jamming of details of the internal device of the check point: forks, rams or synchronizers To sort, check a condition of details. To replace the worn-out or damaged details.
The coupling case in a back part of a case of coupling is not centered
The brand of the filled-in oil does not correspond to recommended To replace oil.
Wear of the blocking rings of synchronizers and conic surfaces of the conducted gear wheels To check a gap between a gear wreath of the conducted gear wheel and the blocking synchronizer ring. The gap has to be not less than 0,77 mm. If the gap meets standard, then it is necessary to check wear of conic surfaces of the blocking ring and the conducted gear wheel.
Gnash at gear shifting
Wrong adjustment of coupling To adjust.
Jamming of draft or cable of the drive of coupling To find the reason of jamming and to eliminate, grease the rubbing places.
The coupling case is not centered To check coaxiality on an opening in a back part of a case of coupling.
Low level of oil or brand of the filled-in oil does not correspond to recommended

To replace oil. To check existence of a leak of oil (if low level is noted). To eliminate leaks.

Wear or damage of details of gear shifting or synchronizers To sort and check a condition of details. To replace worn-out details.
The increased noise from transmission
Low level of oil or brand of the filled-in oil does not correspond to recommended To replace oil. To check existence of a leak of oil (if low level is noted). To eliminate leaks.
Weakening of an inhaling of bolts of fastening of a case of coupling or case of transmission To check an inhaling, to tighten bolts a dynamometer key.
Hit in a case of the check point of third-party particles (dirt, metal sawdust, shaving, etc.) To merge oil, to wash out a case and to fill in fresh oil.
Wear or damage of details of gear shifting, gear wheels, details of fastening of bearings To remove the check point, to sort and check a condition of details. To replace the worn-out and damaged details.
The coupling case is not centered To check coaxiality on an opening in a back part of a case of coupling.
Spontaneous switching off of transfer
The coupling case is not centered To check coaxiality on an opening in a back part of a case of coupling.
Weakening of fastening of the lever of gear shifting To check wear of a fork of the lever, to tighten the weakened connections.
Wear of a nylon insert of the coulisse or weakening of a nut of the coulisse To remove the gear shifting lever, to check wear of a nylon insert or weakening of an inhaling of a nut. To repair or replace.
Wear or damage of a main shaft of the check point or roller bearings To replace a main shaft of the check point or roller bearings.
Wear or damage of the mechanism of gear shifting: forks, rams, rods, coupling, clamps, springs, wear or damage of a cover To remove the check point, to remove the top cover and to check a condition of details in a check point case cover. To replace the worn-out and damaged details.
Wear or damage of teeths of gear wheels, synchronizers, the raised axial side play of a shaft of the check point owing to wear of persistent washers or the conducted gear wheels of a secondary shaft of the check point To remove the check point, to sort and check a condition of details. To replace the worn-out and damaged details.
Wear of the plug of the directing bearing

To replace the plug.

One of transfers does not join
Wear or damage of the mechanism of gear shifting: forks, rams, rods To remove the check point, to remove the top cover and to check a condition of details in a check point case cover. To replace the worn-out and damaged details.
Wear of a ball of a clamp, breakage of a spring of a clamp or weakening of a cover of clamps To tighten cover bolts, or to replace worn-out details.
Wear or damage of the lever of gear shifting To replace the lever.
One of transfers is not switched off
Wear or damage of rods (or rod), deformation of a fork, weakening of the screw of the ram, loss or wear of a spring of an average clamp To check a state and to replace worn-out details.
Breakage of teeths of gear wheels of an intermediate shaft, main shaft, or shaft of an intermediate gear wheel of a backing To check a state and to replace worn-out details.
Wear or damage of the lever of gear shifting, wrong assembly or breakage of the mechanism of gear shifting, wear or damage of teeths of gear wheels, synchronizers and details of their fixing To sort the check point, to replace worn-out details and it is correct to collect.
