10.5. Removal, survey and installation to the place of coupling squeezing mechanisms

Release bearing

Survey

 PERFORMANCE ORDER

1. Remove transmission and strongly establish it on a working surface.
2. Rotate the release bearing in the directing plug, listening to the sounds made by it; existence of the scraping or roaring sound indicates or existence of pollution in the bearing, or malfunction of the bearing. In both cases the release bearing has to be replaced as it is described below.
3. Similarly, if the release bearing hardly rotates or too strongly dangles on the place, it indicates its excessive wear and the bearing is subject to replacement.
4. In view of the insignificant price of the release bearing, and also considerable difficulties connected with ensuring access to it it makes sense to replace always the release bearing, irrespective of its state at removal of transmission for survey or replacement of coupling.

Removal

 PERFORMANCE ORDER

By means of two screw-drivers take the release bearing from the directing plug of the executive cylinder on a main shaft of the transmission. For simplification of its installation into place, pay attention to its orientation.

Installation into place

Install the bearing into place, having pushed the goffered cuff of a boot back and having just put on the bearing the directing plug of the executive cylinder.

Case of the executive cylinder

Removal

 PERFORMANCE ORDER

1. Remove transmission and strongly establish it on a working surface.
2. On a wall of the case of the executive cylinder weaken nipple connection on the bases of hydraulic tubes of giving and return. Disconnect both tubes from a cylinder casing.
3. Weaken and remove three screws of fastening of the case of the cylinder to an internal surface of a dome of coupling. Through a main shaft of the transmission take out the case from a coupling dome. Remove and throw out a sealing ring, at installation new has to be used.
4. Wring out corrugated cuffs of boots and take out the release bearing from the directing plug.
5. Then remove corrugated cuffs of boots.

Installation into place

 PERFORMANCE ORDER

1. Put on a corrugated cuff, a boot the directing plug and install into place the release bearing.
2. In a flute of a back part of the case of the executive cylinder establish a new sealing ring; for deduction of a ring in a flute in the course of installation grease it with slightly universal lubricant.
3. Apply the case of the executive cylinder to a coupling dome. Grease carvings of three fixing screws with a compound for fixing of carvings, then establish and tighten screws.
4. Establish into place hydraulic tubes of giving and return, then strongly delay nipple connections.
