Adjusting the PTO shaft MTZ-80 is not only performed in specialized workshops, but also with their hands. This is a much cheaper process, especially if you have the suitable skills and to understand the peculiarities of technical equipment of the node. Consider the features of this procedure.

MTZ 80 PTO adjustment

First step

Adjusting MTZ-80 is performed in the following sequence (here these numbers correspond to the numbers indicated in the drawing).

Milestones:

  • The eccentric axle is in its original position so that the flatted “In” located in a vertical position on the right side. It must be locked by the stopper 17 and the bolt 16.
  • Next, disconnect the rod 4.
  • Twist the bolt 9, while freeing up the spring 6. For security purposes when turning the bolt 9 ensure that the glass 7 is constantly in contact with the seat until the unclamping spring.
  • Remove the hatch cover on the rear axle, getting access to the screws 13.

In some versions of the tractors adjusting the PTO MTZ-80 is no mechanism of external adjustments in his absence. This particular operation is performed the same way as described above, after repair or Assembly at the factory. On models with a compact cabin the index of the “B” is 50-60 mm.

The braking system and the lack of slip depends solely on the spring fixture. This is especially true of the availability of working areas and aggregating them leverage.

  • Establish glass in gathering with a spring in the recess of the tank, while there will be a slight rotation of the locking bolt. The force of compression spring with a glass – is not less than 200 kgs.
  • Made fixing the Assembly in a compressed state by means of a bolt which is screwed into the nut welded to the lid.
