3.2.1. Removal and installation of the oil pump
For removal and installation of the oil pump it is necessary to execute following operations:
- To merge engine oil. If the operating time of the oil filled in in the engine still is insignificant, it can be collected for a reuse.
On dismantle of a gear belt it is possible to address to подразд. 2.7.1. The general sequence of carrying out of operations is that:
- To turn on above bolts of fastening of a cover of a gear belt and to remove it;
- To dismantle поликлиновой a belt;
- To turn away a bolt of fastening of a belt pulley of a cranked shaft. For this purpose to include any transfer and to brake the car a lay brake, not to admit rotation of a cranked shaft. To remove a pulley;
- To turn away bolts of fastening of the bottom safety guard of a gear belt and to take out it;
- To liberate a gear belt, having weakened a tension roller, and to remove a belt;
- To turn away bolts of fastening of the oil pallet (see подразд. 3.1);
- To turn away bolts of fastening of a cover of a cuff in a forward part of the block of cylinders and to remove a flange with consolidation. From the interior of a cover there is a condensing plug – it is necessary to examine it. If the cover is damaged, it is necessary to replace it. Before flange installation again to establish the plug in a cover, carefully having greased it;
- To beat out from a cover a cuff of a cranked shaft;
- To disconnect the oil pump from the block of cylinders, to remove a chain from an asterisk of a cranked shaft and to take out upwards the pump with a chain.
Fig. 92. Check of a tension of a chain of a drive of the oil pump: a=4,0-5,0 mm
Pump installation is spent to sequences, return to removal. To achieve a tension of a chain of the pump demanded by the instruction, it is necessary to fix the pump bolts on the block of cylinders that it could not move, and then press a thumb a chain as it is shown on fig. 92
. The amplitude of fluctuations chains (size) should make 4,0–5,0 mm. Otherwise it is necessary to weaken a tension of bolts of the pump, to move it and again to tighten bolts. If a chain and (or) the pump have been replaced, the given size should be finished to 3,5–4,5 mm. Again to check up. Then to tighten bolts of fastening of the pump the moment 20 Н·м
To establish a flange of a sealing ring with a new sealing ring and a new lining and to tighten bolts in regular intervals the moment 10 Н·м. At installation and a tension of a gear belt it is necessary to follow the instructions containing in подразд. 2.7.1.
