Checking the left lower arm
1 – mandrel for centering the ball joint; 2 – lower arm; 3 – hole for mounting pins of device A.95716; 4 – device A.95716 for checking levers
Checking the left upper control arm
1 – ball joint; 2 – mandrel for centering the ball joint; 3 – upper arm; 4 – finger for centering hinges; 5 – device A.95716
The deformation of the upper and lower arms is determined using device A.95716.
Install the lower arm so that mandrel 1 (see fig. Checking the left lower arm) for centering, it was articulated with the cone of the ball joint pin of the lever, and the installation pins of the device entered the holes 3 of the lever axis.
The centering mandrel must fit into the right or center hole of the device, depending on which lever is being checked, right or left.
A sign of lever deformation is the impossibility of inserting the device into the holes 3 of the lever axis without force from the fingers, as well as poor articulation of the mandrel 1 with the cone of the ball joint pin.
The upper arm is mounted on the fixture (see fig. Checking the left upper arm) in an inverted position so that the mandrel 2 for centering exactly coincides with the tail of the ball joint pin 1, and the pin 4 passes through the holes of the rubber-metal joints of the lever.
The amount of deformation of the lever is determined by the difficulty of inserting pin 4 into the holes of the lever hinges and by the poor articulation of the conical socket of the mandrel 2 with the conical surface of the pin of the ball joint 1. Pin 4 should enter the holes of the hinges without much effort. If the deformation is small, the levers are adjusted, and if large, they are replaced.
