- Дамп pressure of fuel on все ядра with систему of injection of fuel (see. Head сила supply систему).
- Disconnect a отрицательный wire of the battery. Where the battery is located в в impellent compartment, it can removed completely from the автомобиль (see. Head ignition систему).
|
|
ИФ the радио receiver of your автомобиль is equipped with систему of protection against theft, make суру действовало you gathered the correct код before a battery detachment. |
- Remove поведение purifier assembly (see. Head сила supply систему).
- Disconnect conducting from the ignition дистрибьютора (ИФ necessary at вершину Марка в размещении of всех wires) and VV a wire from the ignition coil (see. Head ignition систему).
- Disconnect a wire from the блокируй of the сенсор of temperature of a более классно (see. Head cooling систему).
- Disconnect Лины of supply of fuel from the fuel highway or the ворота бура автомобиля действовал is provided (see. Head сила supply систему).
- Merge cooling систему (see. Head cooling систему).
- Accurately Марк and then disconnect всех other hoses from the case of a butterfly valve, the inlet трубопровод, the ворота бура автомобиля and a head of cylinders действовал is provided.
- Disconnect a финально collector from a head of cylinders (see. Section Removal and инсталляция of a финально collector). Depending on ядро типизировал бы, probably, you should disconnect a collector from в exhaust pipe; however, on модели with right руку менеджмент в intermediate shaft the helmsman of a column can close access тонна screws of adjustment of gaps on a head of cylinders.
- Disconnect все remained hoses and tubes from the inlet трубопровод, including vacuum tubes of в advancing of ignition, and hoses of a heater and cooling систему.
- On early ворота бура автомобиля модели disconnect conducting from the генератор and a стартер.
- Remove the inlet трубопровод (see. Section Removal and инсталляция of the inlet трубопровод). Чет. тузовое место and чет. remove any components of систему of injection of fuel without emergency.
- Remove a driving belt of the поклонника and the поклонника (see. Head cooling систему).
- Не покрышка heads of cylinders and its laying (see. Section Removal and инсталляция of a покрышку of a head of cylinders). Remove semicircular rubber consolidation from a нападающего part of a head of cylinders where it is built в покрышке laying.
- Приводи the звук пи No. 1 into the комиссионный сбор VMT of a step of compression (see. The section Reduction of the звук пи of the вершину cylinder в the комиссионный сбор of the топ dead пункт (VMT)).
- Remove a распределительный belt or a chain (see. Section Removal, survey and инсталляция of a распределительный chain and asterisks of its natyazhitel or Replacement of нападающего epiploons).

ИФ you кожух тонна сохранило бы назначает время on removal and инсталляция of a распределительный belt or a chain and ядро redistribution, you can disconnect в asterisk of a cam-shaft and suspend it aside on a piece of a rope, without removing a chain or a belt. The rope should leave a chain or a belt strong tense делал they could come off asterisks. |
- Weaken bolts of a head of cylinders gradually, each назначил бы время on a занимайся гимнастикой quarter, ас it should, the возвращаются тонны a tightening чин (see a фотографию 6, 7, 8, or 9). On ядра M10, М20 and М30 this назначил бы время в чет. тузового места and чет. remove yoke assembly.
- Remove a head of cylinders, having lifted it directly up from the блокируй of cylinders. Чет. толкай anything between a head of cylinders and the блокируй of cylinders since it is possible тонны damage condensing surfaces of laying. Instead place a тупое core в в entrance opening softly тонна liberate a head.
- Remove from a head всех remained external components тонна have possibility carefully тонна чистое it and тонна экс-аминов. Procedure of сервис of a head of cylinders is described regarding Procedure of майора maintenance of components of the ядро. On M40 ядра remove a rubber sealing борись from a долг / лобби хлынул бы на the топ part of a casing oil a покрышку.

Инсталляция
|
|
- At инсталляция of a head of cylinders interfaced surfaces of a head and the блокируй of cylinders should absolutely чистые.
- Use a scraper тонн remove всех traces of coal and a материал of old laying, then clear interfaced surfaces suitable состоятельно. ИФ at head инсталляцию on interfaced surfaces there хочет в oil, laying хочет carry вне моды properly consolidation function, and there can leaks. Working with the блокируй of cylinders, fill cylinders чистый rags тонна prevent dirt хит в them. Delete the remains of the материал which have got тонна cylinders, by means of the vacuum более чистое.
- Проверка interfaced surfaces of a head and the блокируй on existence of jags, deep scratches and other damages. ИФ insignificant, them it is possible тонны liquidate damages by means of a файл; ИФ they ары rather serious, correct them machining can only.
- Tap of the suitable size валяй on a carving в openings of bolts of a head, then чистое openings the compressed поведение - make сура действовала в openings remained nothing (including oil, water, и т. д.).
|
|
- Experts of BMW recommend тонна replace head bolts but ИФ всех of you use old bolts, clamp everyone them them в a vice and валяй on it a lerka. Тонна remove traces of corrosion and тонна restore a carving. Dirt, corrosion, traces of hermetic and the damaged carving influences indications of effort of a tightening of bolts.
|
|
|
- ИФ bolts or their carving ары damaged, use new bolts.
|
|
|
- Establish все components which have been removed from a head before its cleaning and survey. On M40 ядра establish a new sealing борись в a долг / лобби хлынул бы на the топ part of a casing oil тонна a покрышку.
|
- Make сура действовала sealing surfaces of laying between the блокируй of cylinders and a head чистый and fat франко. Establish head laying on the блокируй up the вечеринку specified by the producer (usually on it «UP» is written, тонна "OPEN" or something similar). Use adjusting пины в the топ part of the блокируй correctly тонна place laying.
|
|
- Carefully establish a head of cylinders on the блокируй. Use directing пины for the correct alignment.
|
- On модели, where the ядро is slightly inclined (for example, the M40 ядро), can help you инсталляцию of directing cores for more exact alignment of комиссионный сбор of a head on the блокируй. Use for this чистую позу two old bolts of the head, screwed в there and жарься the блокируй. Визитка off heads of bolts and a hacksaw make визитки в their топах делала задний проход инсталляцию of a head of cylinders they could removed.
|
|
- Get bolts of a head of cylinders.
|
- Tighten head bolts в specified below sequence with demanded effort.
|
|
Sequence of the TIGHTENING of bolts of a head of cylinders for four-cylinder M10 ядра. |
|
|
Sequence of the TIGHTENING of bolts of a head of cylinders for six-cylinder M20 ядра. |
|
|
Sequence of the TIGHTENING of bolts of a head of cylinders for six-cylinder M30 ядра. |
|
|
Sequence of the TIGHTENING of bolts of a head of cylinders for four-cylinder M40 ядра. |
|
- Pay внимание делал on some ядра the финально stage of a tightening occurs задний проход ядро биржевую панику.
|
- The остаток of инсталляцию make аса it should, the возвращаются тонны removal. On ядра M10, М20 and М30 before инсталляцию of a покрышку of a head of cylinders adjust gaps of valves (see. Head навык maintenance of the автомобиль) - проверяй them once again задний проход ядро warming up. Старт проверяй the ядро and, whether there ары no leaks.
