Installation
|
|
- Clear interfaced surfaces and combustion chambers. Blow carving openings under bolts of fastening of heads of cylinders the compressed air to remove from them oil and dirt.
- Make sure that the directing are established in blocks of cylinders.
- Establish heads of cylinders with new laying and bolts.
|
|
Pay attention that bolts have various length, roll them in the corresponding openings. Make sure that laying is laid on the corresponding blocks of cylinders (on laying labels of "L" – left are put, - and «R» – right). The thickness of laying gets out according to Specifications. |
- Tighten bolts of fastening of heads of cylinders in sequence, return specified illustrations item 54 (Removal) and with demanded efforts (see. Specifications).
- Further installation is made in sequence, return to an order of dismantle of components. Pay attention to the next moments:
- Tighten fixture according to requirements of Specifications;
- Use a new submitting tube of TNVD;
- Use new consolidations of nozzles;
- At installation of a cover of a head of cylinders use new laying, and also put hermetic (No. 87 81 841 according to the Saab catalog) on surfaces;
- At installation of the pipe connecting blocks of cylinders, use new laying and grease fixing bolts with means of Molycote 1000;
