Replacing the cuffs inside the hydraulic unit. Oil leak from the Chery QQ robot selespeed robot
Hello everyone
The video was filmed quite a long time ago, the car successfully drives after the repair without new oil leaks. Also a little later I will add to everyone the sizes of the seals that I used.
The sizes of the cuffs that I changed are 20 x 13 x 5 mm, these are the sizes of the factory cuff. I installed polyurethane 20 x 13 x 5.5 mm.
The retaining ring that holds the plug is 34 mm thick 1.5
The O-ring that is on the plug is 27 mm internal diameter thickness is approximately 2.5 -2.7 it is difficult to measure a used ring.
