2.2.15. Cleaning of the block of cylinders
|
|
The caps established in channels of cooling of the block, can be taken hardly or even not to be taken at all. |
|
|
- Take from the block of cylinders of a cap. For this purpose with a hammer and a punch strike in the block on one party of a cap, big flat-nose pliers grasp for its other edge and pull out.
- Remove with a scraper from the block of cylinders all traces of a material of laying. Be very careful not to leave on condensed surfaces of the tease or a dent.
- Remove covers of radical bearings and separate from covers and the block of cylinders loose leaves of bearings. Note to which cylinder bearings belong and they were established in a cover or in the block, and then put aside.
- Take from the block all caps of oil pipelines, Caps are usually established very hardly - probably it is required to drill them and to clean openings a tap. At assembly of the engine use new caps.
- If the engine is strongly polluted, it is necessary to send it for cleaning by steam in a mechanical workshop.
- After block return from a mechanical workshop once again clean openings and channels of oil pipelines. In the majority of shops of autoaccessories there are special brushes. Wash out channels water while it will not begin to follow pure, carefully drain the block and grease all otfrezerovanny surfaces with light anticorrosive oil. If the compressed air is available, for acceleration of drying use it, and blow them all openings and channels of oil pipelines.

|
When using the compressed air protect eyes! |
- If the block is not strongly polluted or polluted by dirt, the corresponding cleaning can be made hot soap solution and a rigid brush. This work carry out carefully and allocate for it time enough. Irrespective of methods of cleaning be convinced that all openings and channels of oil pipelines are cleaned very carefully, the block is dried completely up and the processed surfaces are covered with light oil.
|
|
- Carving openings in the block for exact measurements of efforts of a tightening at assembly should be cleaned. For removal of a rust, corrosion, a carving compound or dirt wrap in each opening a tap of the corresponding size. If it is possible, clear after this operation of an opening of garbage the compressed air. Be convinced that dry - oil or other liquid can lead all openings to that at a tightening of bolts because of hydraulic pressure the block will burst. The turn now came to clear carvings of all bolts. Pay attention that BMW recommends bolts of a head of cylinders and radical bearings to replace new.
|
- Establish covers of radical bearings and a hand tighten bolts.
- After drawing on condensing surfaces of a suitable compound establish them in the block. Be sure that they are established plainly and against the stop, differently there can be a leak. For this purpose there are special tools, however, also successfully it is possible to apply a face head which can be inserted into a cap, the extension piece on 1/2 inches and a hammer.
|
|
- Put on new caps of oil pipelines non-drying hermetic and wrap them in block openings. Be convinced that they are reliably tightened.
|
- If the engine is not supposed to be collected further, for preservation it in purity cover the block with a big plastic package.
