3.3.8.2. Crankshaft

Installation

PERFORMANCE ORDER
1. Arrange the block so that the lower part was turned up.
2. Turn out bolts of covers, get covers and spread out them as their installation.
3. Get from covers and the block of cylinders old loose leaves and absolutely wipe covers and beds.
4. Clear an external surface of new radical loose leaves with oil flutes, and carefully enclose them in a bed of the block of cylinders.
5. The corresponding response loose leaves enclose in covers, having combined ledges with samples.
6. Loose leaves not to grease.

Check of gaps

PERFORMANCE ORDER
1. Establish persistent half rings in deepenings of the block of cylinders. On engines 2F and 3F-E of a half ring are established near a support of the 3rd bearing, on engines 1FZ-FE – near a support of the 4th bearing.
2. Establish the crankshaft and measure gaps in radical loose leaves. For this purpose put on a piece of a calibration wire (it is specified by an arrow) on each radical neck of the crankshaft parallel to its axis.
3. Clear surfaces of loose leaves in covers, establish covers and tighten bolts in three steps with the set moment, beginning from the center and being displaced to the periphery.
4. Unscrew bolts and carefully lift covers, compare thickness of each of crushed a provolok to a scale on packing and define gap size. Crankshaft rotation at measurements is not allowed.
5. If the gap does not correspond to norm, the wrong selection of dimensional group of loose leaves can be the reason.
6. Be convinced that at measurements between bearings and surfaces of covers there were no pollution or oil. If the width of the crushed wire on the ends strongly differs, the radical neck of the crankshaft has a konusnost.
7. Remove from necks the remains of a wire and remove the crankshaft.
8. Grease with molybdenic greasing radical loose leaves and a face surface of the persistent radical bearing. Establish in the block of cylinders of section of a back (demountable) epiploon and a cover of the back radical bearing.

Final installation of the crankshaft

PERFORMANCE ORDER
1. On the engine 1FZ-FE establish in the block of cylinders oil nozzles and control valves.
2. Be convinced of purity of necks of a cranked shaft, then establish it in the block of cylinders. Clear surfaces of loose leaves in covers and put on each of them a thin layer of greasing.
3. Establish covers on the former places so that shooters were turned towards a forward part of the engine.
4. Wrap bolts of covers of radical bearings.
5. Tighten bolts of all covers except a cover of the persistent radical bearing with the set moment. Bolts tighten in 3 stages, beginning from an average part and being displaced to the periphery.
6. Tighten bolts of a cover of the persistent radical bearing with the moment of 1,0-1,2 N of m.
7. In easy blows of a lead or brass hammer shift the crankshaft back to combine persistent surfaces of radical bearings and the crankshaft.
8. Release bolts of covers and again tighten with the set moment, beginning from an average part and being displaced to the periphery.
9. On cars with automatic transmission replace directing bearing of the crankshaft.
10. Check freedom of rotation of the crankshaft.
11. Check axial люфт the crankshaft (see subsection 3.3.7.4). Люфт should correspond to norm if new bearings and persistent half rings are established are not worn-out.
12. On cars with an one-piece back epiploon establish a new back epiploon.
