We are faced with the task of replacing a silent block with an outer metal collar with a silent block without an outer metal collar. Knowing the dimensions of the seat and the dimensions of the silent block in advance, we selected a mandrel for pressing out and a support for the lever, taking into account that it does not interfere with the exit of the silent block from the seat. Dismantling the old silent block. We install the support on the press. We put the lever with the silent block on top of the support, install the mandrel, pre-selected according to the dimensions of the silent block. We set all this coaxially with the press rod and begin pressing out the silent block. We carefully monitor that there are no distortions, so as not to damage the seat in the lever with the mandrel. And we begin to increase the load on the press, the main thing is without jerks. The silent block comes out of the seat. The silent block has been safely dismantled from the seat. Old silent block. Preparing the seat. After dismantling the silent block, we assess the condition of the seat for dirt, rust and burrs. If we leave dirt, rust and burrs in the seat, we can damage the silent block without the outer metal collar. We remove dirt and rust with a wire brush, if possible, going over the entire surface of the seat. If there are burrs in the seat, we take a file for this. We use a file to remove burrs that can damage the silent block. After making sure that there are no shavings in the seat, we can proceed to installing the silent block without the outer metal collar. Preparing the silent block for installation We have a silent block that we must mount in place of the old silent block that was just pressed out. In the package, we have a silent block without an outer metal collar, grease for mounting this silent block, and we also have instructions for installing a silent block without an outer metal collar in the package. In order for the installation of a silent block without an outer metal collar to go smoothly and without losses, we need to lubricate the silent block and the seat in the lever with the grease applied to the parts. Our silent block is symmetrical, which side to press the silent block is not important. The side into which the silent block will enter the seat must be lubricated. We also lubricate the seat. The lever and silent block are ready for installation. When installing a silent block without an outer collar, the force on the silent block must be applied to the inner sleeve, using a mandrel with a diameter equal to the inner diameter of the inner sleeve. Please note that the distance between the flanges is less than the width of the seat. But this will not prevent us from installing the silent block, because the seat diameter of the silent block is larger than the seat diameter in the lever. Due to the deformation of the inner part of the silent block, it will stretch and the thrust collars will go beyond the seat. Due to the elastic deformation, the silent block will be fixed in the seat. Installation of a new silent block. To install a silent block without an outer metal collar, we use the same stand on which we dismantled the old silent block. Let me remind you that we install the silent block on the lever, on the seat, with the lubricated output side. We install the mandrel we selected in the silent block and begin installing the silent block. We align the entire structure coaxially and increase the pressure on the press. Initially, the silent block may not go straight into the seat, this is determined by the difference in the diameters of the seat and the silent block. The silent block begins to enter the seat, but with a slight skew. Gradually increase the pressure on the press. The silent block entered the seat, we continue pressing it in. In order for the second flange to come out of the seat, we slightly push the silent block into the lever in the seat. We relieve the pressure on the press, pull out the silent block and look. The silent block did not reach, so we continue installing the silent block. We set the entire structure coaxially, we begin to increase the pressure on the press. Checking the quality of installation. We look, the second flange came out of the seat. In order to eliminate the asymmetry of the seat and the silent block, we clamp the inner metal sleeve of the silent block in the clamps and with movements, rotating, align the silent block in the seat. Here we see that the silent block is located symmetrically in the seat. The thrust flanges closed the seat on both sides. The lever is ready for installation.
