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 inserts and absolutely wipe covers and beds.
4. Clear an external surface of new radical inserts with oil flutes, and carefully enclose them in beds of the block of cylinders.
5. Enclose the corresponding reciprocal inserts in covers, having combined ledges with selections.
6. Not to grease inserts.

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. Install the crankshaft and measure gaps in radical inserts. 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 inserts 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. Turn off bolts and carefully lift covers, compare thickness of each of crushed a provolok with a scale on packing and determine gap size. Rotation of the crankshaft at measurements is not allowed.
5. If the gap does not meet standard, then the wrong selection of dimensional group of inserts can be the cause.
6. Make sure that at measurements between bearings and surfaces of covers there were no pollution or oil. If width of the crushed wire on the ends strongly differs, then the radical neck of the crankshaft has conicity.
7. Remove the remains of a wire from necks and remove the crankshaft.
8. Grease with molybdenic lubricant radical inserts and the face surface of the persistent radical bearing. Install 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 install oil nozzles and control valves in the block of cylinders.
2. Be convinced of purity of necks of a bent shaft, then install it in the block of cylinders. Clear surfaces of inserts in covers and apply a thin film of lubricant on each of them.
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. Tighten bolts in 3 stages, beginning from a middle part and being displaced to the periphery.
6. Tighten bolts of a cover of the persistent radical bearing with m 1,0–1,2 N.' moment.
7. Easy blows of the lead or brass hammer shift the crankshaft back to combine the persistent surfaces of radical bearings and the crankshaft.
8. Release bolts of covers and again tighten with the set moment, beginning from a middle part and being displaced to the periphery.
9. On cars with automatic transmission replace the directing crankshaft bearing.
10. Check freedom of rotation of the crankshaft.
11. Check an axial side play of the crankshaft (see subsection 3.3.7.4). The side play has to meet standard if new bearings are installed and persistent half rings are not worn-out.
12. On cars with a one-piece back epiploon establish a new back epiploon.
