Blow out the cylinder head and mounting holes for the
seal and nonreturn valves with dry, oilfree com
pressed air, and if necessary wipe off any adhering
sealing compounds with a clean cloth. If necessary,
also remove sealing compound from the balls 

(serial

no. 65 27 132) and springs 

(serial no. 65 27 131) of

the nonreturn valves (see figure 4).
Check the Orings 

7

 (serial number 65 27 119) of all

the valves and replace if necessary.

8

Carefully insert the complete nonreturn valves in their
previous mounting holes.

9

Place the cylinder heads on the table, with the mount
ing hole for the piston seal at the top. Centre the
mounting tool (serial number 65 27 117) with the mark
ing “T1757, THIS SIDE UP” on the top of the cylinder
head.

10

Insert a new piston seal 

(serial number 65 27 118),

with the open side (spring) facing down, in the conical
hole of the mounting tool, and press it evenly and
straight into the cylinder head using the previously re
moved pressure piece.

11

Check the piston play in the guide sleeve. To this end,
fully remove the pistons on each side of the pump,
while firmly holding the guide sleeve 

(serial no. 65 27

120) and pressure disk 

(serial no. 65 27 372). With

the plate firmly held, piston 

must have a maximum of

0.1 mm play in the sleeve. If the play is greater, both
parts must be replaced.

12

Check the piston for scratches and wear.

13

Clean the piston up to the retaining plate, removing any
adhered impurities.

 Keep free of oil and grease

.

14

Allow the piston to project the same length from the
pump sides, and carefully push the cylinder heads into
their original position above the pistons (

OUT 

must be

at the front in each case).

15

Tighten the cylinder head bolts with a torque wrench
(20 Nm or 175 in.lbs), working in diagonally opposed
sequence.

16

Connect the pipes and check for leaks.

17

Remount the thermostat.

18

Flush the system.

MAINTENANCE AND SERVICING

7

Продуйте головку цилиндра и монтажные отверстия
для уплотнителей и невозвратных клапанов сухим
безмасляным сжатым воздухом; при необходимости
сотрите чистой тканью любые следы герметиков. При
необходимости также удалите герметик с шариков 

5

(код заказа 65 27 132) и пружин 

(код заказа 65 27

131) невозвратных клапанов (см. рис 4).
Проверьте уплотнительные кольца 

(код заказа 65 27

119) всех клапанов и замените при необходимости.

8

Осторожно вставьте собранные невозвратные кла
паны в их прежние монтажные отверстия.

9

Поместите головки на стол, установочным отвер
стием для уплотнителя поршня наверх. Центрируй
те монтажный инструмент (код заказа 65 27 117)
маркировкой “T1757, THIS SIDE UP” поверх голов
ки цилиндра.

10

Вставьте новый уплотнитель поршня 

(код заказа

65 27 118) открытой стороной (пружиной) вниз, в
коническое отверстие монтажного инструмента, и
вдавите его равномерно и прямо в головку цилинд
ра, используя предварительно вынутую нагнета
тельную часть.

11

Проверьте зазор между поршнем и направляющей
гильзой. Для этого, полностью снимите поршни на
каждой стороне насоса, твердо удерживая направ
ляющую гильзу 

(код заказа 65 27 120) и упорную

шайбу 

(код заказа 65 27 372). Если твердо дер

жать пластину, то поршень 

должен иметь зазор в

гильзе не более 0.1 мм. При большем зазоре обе
части необходимо заменить.

12

Проверьте поршень на наличие царапин и призна
ков износа.

13

Очистите поршень до стопорной пластины; удалите
любые налипшие загрязнения. 

Сохраняйте его

свободным от смазки и масел

.

14

Позвольте поршням выступать на ту же длину по
сторонам насоса, и осторожно установите головки
цилиндров на их исходное положение над поршня
ми (в каждом случае 

OUT 

должно быть впереди).

15

Затяните болты головки цилиндра ключом с огра
ничением по крутящему моменту (20 Нм), пооче
редно по диагонали.

16

Подсоедините трубки и проверьте  утечки.

17

Установите на место термостат.

18

Продуйте систему.
