2.2.26. Инсталляция of звука пи / rods в collecting and проверяй of lubricant gaps в bearings of rods
|
|
- Before инсталляция of pistons/rods assembled вала of cylinders should irreproachably чистые, the facet and a cranked shaft should removed from the upper edge of each cylinder should established.
- Remove from a rod of No. 1 покрышка (address тонна the Марка маде at removal). Remove формовщика loose leaves of bearings and wipe surfaces of bearings of a rod and a покрышку чистые, leaving fibers, a fabric. They should irreproachably чистые.

Проверка of lubricant gaps of bearings of rods
|
|
- Clear a жарься surface of the new топ loose leaf of the bearing, then establish it on a rod. convinced действовал the ledge of the loose leaf of the bearing coincides with deepening в a rod. Чет. молот the bearing loose leaf into place a молот and very careful тонна leave on a surface of scratches or jags. Again convinced действовал the ledge of the loose leaf coincides with deepening в a покрышку, and чет. put some any greasing. It is essentially важно, действовал being interfaced surfaces of the bearing and a rod at this проверяй irreproachably чистый and without oil.
- Establish gaps of звук пи вокруг under углового удара 120 ° тонна each other.
- Put on each стучит of a покрышку of a rod a piece of a plastic or rubber тюбика.
- Grease the звук пи and вокруг with чистый impellent oil and establish on the звук пи a szhimatel. Leave a skirt of the звук пи of acting on 6 or 7 мм тонны insert the звук пи into the cylinder. Вокруг should compressed until they хочет appear aflush with the звук пи.
- Занимайся гимнастикой a cranked shaft действовал the поддразнивай of the bearing of a rod No. 1 appeared в NMT (the bottom dead пункт). Put on cylinder вала a layer of impellent oil.
- Carefully insert a piston/rod assembled into the cylinder No. 1, having directed a метка or визитку on the звук пи bottom towards в ядре работает принудительно, and остаток bottom edge of a szhimatel against the блокируй of cylinders.
- Strike on the upper edge of a szhimatel of вокруг тонна convinced действовал it on всех circle contacts тонна the блокируй.
|
|
- Slightly strike on the звук пи bottom with the wooden действовал бы of a молот, thus directing the rod on a поддразнивай of a cranked shaft. Working slowly ИФ at звук пи advance on cylinders resistance is felt, immediately suspend прессинг. Находи действовал disturbs and eliminate the reason. Under no борись в circumstances чет. apply force - it is possible тонны повозки a and / or the звук пи.
|
|
|
Звук пи вокруг before the entrance в the cylinder can jump вне моды from a szhimatel therefore render on a szhimatel of pressure. |
- When pistons/rods хочет assembled established, before a финально tightening of bolts of a покрышку of a rod it is necessary тонна проверяй a lubricant gap of the bearing.
- Визитка off a piece of a plastic wire of the corresponding size, it is a little less than a width of the rod bearing, and lay it on a rod No. 1 поддразнивай, параллельно тонна в axis of a cranked shaft.
- Clear a surface of the bearing of a покрышку of a rod, remove from rod bolts protective tubes and establish a rod покрышку. convinced действовала the метка on a покрышку coincides with a метку on a rod.
- Establish nuts, bolts and tighten with the effort specified в the Size table and adjusting data at the of the менеджмент. On ядра M10 and М30 reach финально effort в three stages.
|
|
Тонна avoid mistakes в measurement of effort of a tightening, apply a лица head with thin вала which хочет jam between a покрышку of a rod and a шпунт. ИФ a head gets jammed between a шпунт and a покрышку, raise a head действовало it did concern a покрышку a little. During this операцию чет. занимайся гимнастикой a cranked shaft. |
- Unscrew a шпунт and не покрышку a rod, being careful тонна shift a plastic wire.
|
|
- Compare width of the wire тонны вне моды flattened a scale printed on packing of a wire. Compare value тонны requirements of the Size table and adjusting data at the of the менеджмент Тонна convinced of correctness of a gap.
|
- ИФ the gap differs from demanded, loose leaves of bearings can the wrong size (действовало means need of acquisition of new loose leaves). Before making the decision on need of acquisition of other loose leaves, convinced действовал at gap measurement between loose leaves and rods or покрышки there is no dirt or oil. Итак again measure диаметры of a поддразнивай. ИФ the width of a wire что identical, the поддразнивай can have a konusnost (look the Section проверка of условно of a cranked shaft).

Финал инсталляцию of rods
|
|
- Carefully remove from a поддразнивай and / or bearing surface всех traces of a материал of a wire. careful тонна scratch a bearing surface - чет. it by a nail or edge of a credit card.
- convinced действовала тонна a surface of bearings irreproachably чистые, then put on both surfaces в equal layer of disulfidmolibdenovy greasing or impellent oil. For access тонна a surface of the loose leaf of the bearing of a rod it is required тонна толкай the звук пи в the cylinder - at вершина convinced действовала on rod bolts ИФ protective tubes ары applied, put on.
- Бак shift a rod on its place on a поддразнивай and remove from bolts of a покрышку of a rod protective tubes. Establish покрышки of a rod and tighten nuts / bolts with demanded effort.
- Repeat the семя procedure for other звука пи / rods.
- Важно circumstances is the following:
- At assembly кип в irreproachable purity external surfaces of loose leaves and internal surfaces of rods and покрышку.
- convinced действовал в each cylinder the corresponding pistons/rods assembled ары established.
- Визитка or метку on the звук пи should turned тонна в ядре работает принудительно.
- Grease вал of cylinders with чистый oil.
- At инсталляция of покрышки of rods задний проход проверяй of a lubricant gap grease surfaces of bearings.
- Задний проход the correct инсталляцию of всех pistons/rods assembled for этаж taking of obvious jammings by a hand занимайся гимнастикой several times a cranked shaft.
- Проверка латеральное люфт rods (look the Section Removal of a cranked shaft).
- Compare measured латеральное люфт тонна requirements of the Size table and adjusting data at the of the менеджмент Тонна convinced of its correctness. ИФ латеральное люфт before dismantling что correct and the cranked shaft and rods were established начально, it should remain. ИФ the cranked shaft or new rods were established new, латеральное люфт it can appear wrong. ИФ таким образом, rods it is necessary тонна remove and посылай for survey в a mechanical мастер-класс.
