NATYAZHITEL OF THE LOWER CHAIN
| PERFORMANCE ORDER |
| 1. Make sure that demountable surfaces of a natyazhitel and a cover dry and pure. |
| 2. Establish new laying, having oriented so that the cut on laying was combined with a lubricant opening of a natyazhitel. |
| 3. Establish a natyazhitel and tighten bolts with the set moment. |
|
NATYAZHITEL OF THE TOP CHAIN
| PERFORMANCE ORDER |
|
1. On cars of early releases the boot of a natyazhitel has to be taken aside and recorded by a hook. Establish a natyazhitel assembled on a head of cylinders. Tighten bolts of fastening of a natyazhitel with the set moment, remove a hook (it is specified by an arrow). Make sure that the block of a boot of a natyazhitel with a force rested against a chain. |
| 2. On cars of late releases take aside a block of a natyazhitel and record a bar. Establish a natyazhitel and tighten bolts with the set moment. Get a bar and be convinced that the block of a boot of a natyazhitel with effort rested against a chain. |
| 3. Be convinced of purity and lack of traces of moisture and oil on the condensed surfaces of a viewing cover of asterisks of cam-shafts and heads of cylinders. If on a cover laying was established, then replace laying, having established it on a head of cylinders. If consolidation was provided with sealant, then put it on all perimeter of a cover with a continuous layer. Establish a cover and tighten bolts and nuts with the set moment. |
| 4. Establish an arm on the right support of the power unit and tighten bolts with the set moment. |
|
