The gearbox is the very part of any machine that often and at the same time unexpectedly breaks down during operation. Service centers have the necessary equipment and specialists who can solve the problem, but it is much more pleasant to fix everything yourself.
It will not work to go over the gearbox "on the knee", you need a garage or a well-equipped workshop. You will also need work experience and a professional set of tools:
- a set of spanners;
- heads;
- sandpaper;
- glue TB-1324;
- pullers for shafts and bearings;
- new oil, mechanical vice;
- screwdriver, hammer;
- sealant.
It is necessary to be aware of the internal structure of the boxes, as they can differ significantly from one another. Find a manual that only works for your gearbox.
Operating procedure:
- Remove the gearbox from the vehicle. Wash the outside of the box body and clean it. Remove the oil dipstick from the unit. Disconnect the gearshift lever.
- Unscrew the nuts that secure the housing cover. You should not disassemble the shift forks and synchronizers if this is not necessary - navryatli without proper experience you will be able to put them back together. Note that the shaft nuts are very tight.
- After removing the synchronizers, try to wrap them with tape, otherwise they may just fall apart. All seals in the box must be replaced with new ones, the bolts must be cleaned of glue and a new layer of glue must be applied during assembly.
- Carefully inspect the crankcases, they may have mechanical damage - the result of wear. If the cracks are large, then the part requires urgent replacement. Minor scratches can be removed with sandpaper or a grinding disc on a grinder.
- Carefully assess the condition of the bearings as well as the seating areas. At the moment of rotation, the bearing should rotate without jamming and squeaks. If necessary, replace the forks with new ones; the seats should not have any mechanical damage.
- The axle shaft seals must be perfectly flat. It is advisable to change all of them. Evaluate the work of the magnet, you can clean it. Assemble the checkpoint in the reverse order. Place the magnet. Lubricate all rubbing surfaces with ordinary gear oil.
- Seal the surfaces of the rear cover of the gearbox with a sealant specifically designed for metal parts. Select the bearing adjusting ring in the event that you have changed housings, crankcases.
- After the unit is assembled, fill it with new oil of the appropriate brand. Reassembly must be carried out very carefully so that unnecessary spare parts do not form and there is no need to disassemble for a new one (this is far from the most pleasant experience)
Following all of the above instructions, the car owner will be able to disassemble the gearbox of his car, avoiding stupid mistakes
