4.1.15. Removal and installation of a bent shaft and radical bearings

Removal

PERFORMANCE ORDER
1. Remove the engine from the car and then remove all components from the engine.
2. Turn the engine a bent shaft up. Keep in mind that covers of radical bearings of a bent shaft various therefore note their arrangement.
3. Unscrew bolts and uncover radical bearings.
4. Lift a bent shaft and remove a back sealing ring of a bent shaft.
5. Remove radical inserts from the block of cylinders and covers of radical bearings of a bent shaft.

Installation

PERFORMANCE ORDER
1. Check that the block of cylinders both a bent shaft pure and dry, and openings for oil supply pure. If there is an opportunity, blow openings compressed air and fill them with oil.
2. Clear a back part of inserts and the place of their installation in the block of cylinders and covers of radical bearings. Establish inserts on the places.
3. Keep in mind that the ledge on an insert has to enter accurately a groove (it is specified by an arrow) in a cover or the block of cylinders.
4. The central radical insert also defines an axial side play of a bent shaft. The inserts installed in the block of cylinders have an opening for lubricant supply. The insert established in the central cover of the radical bearing also has an opening for lubricant supply.
5. Oil a working surface of inserts pure engine.
6. Install a bent shaft in the block of cylinders of the engine.
7. Grease the lower inserts in covers of radical bearings with pure engine oil and check that ledges on inserts are in cover grooves.
8. Establish the central cover of the radical bearing and fix it by bolts, having tightened them the required moment.
9. Establish a new back sealing ring of a bent shaft, then apply a thin film of sealant on a cover flange.
10. Also fill with flute sealant from two parties of a back cover of the radical bearing of a bent shaft.
11. Establish a back cover of the radical bearing of a bent shaft and fix it by bolts, having tightened them the required moment.
12. Establish a forward cover of the radical bearing of a bent shaft. Apply a sealant layer on bolts and fix a cover by bolts, having tightened them the required moment. The cover has to be established aflush with the block of cylinders of the engine.
13. Turn a bent shaft of the engine and check that it rotates easily and smoothly. Using a probe edge, check an axial side play of a bent shaft. If the axial side play of a bent shaft exceeds admissible limits, so radical inserts of the inappropriate size are set or they are worn-out.
