Removal, check of a condition and installation of the converter of rotation (hydrotransformer)



1. Establish a transmission the rotation converter up.
2. Turn a plastic finger of the converter of rotation on 1/4 turns counter-clockwise.
3. Tighten handles (065) on the rotation converter
4. Take the rotation converter.


The case of the converter of rotation has the following nominal overall dimensions:

Diameter, mm
Height, mm
New assembly
Maximum permissible value


1. Establish the rotation converter assembled with the secondary pump a leading flange up on a measuring plate (05).
2. Measure dimensional height of "A" of the case of the converter of rotation. If the result of measurement exceeds limiting admissible value, replace the converter.



1. Grease a flange (32) means of Molykote.
2. Establish a plastic finger and turn it on 1/4 turns clockwise.
3. Unscrew handles (065) from the rotation converter.
4. By means of a calliper measure size of a vystupaniye of "A" of the converter of rotation over an interfaced surface of a case of transmission. The nominal rate makes 9.6 mm.
