a. Make a reference mark (in-line) on socket (A) andcylinder head surface (B).
b. Loosen cap screw at least 1-2 turn.
c. Retighten cap screw (using a torque wrench) untilreference marks align and record torque.

添加剂主要用于保护冷却水道表面不被损坏。如果冷却中未使用添加剂或添加剂含量偏低,将会造成以下损坏:
水道表面腐蚀
矿沉积
水道表面锈蚀
冷却水积垢
缸套穴蚀
冷却水起泡
在使用中,冷却水添加剂会被不断地消耗,其浓度也会随之,因此应定期向发动机内加入补充用冷却水添加剂(补冷剂)或向长效冷却液中加入长效冷却水剂(长效剂)来冷却水添加剂的浓度。
CAT柴油机喷油器同步
需要工具:
6V3119齿杆同步表。
喷油器同步就是所有的喷油器齿杆到一相关位置,使每个喷油器到各缸的燃油量相等。这一工作是在控制连接件在某一固定位置时(称为同步位置),通过把每个喷油器齿杆到相等位置来完成。喷油器同步的如下:
1、固定盖(3)的顶螺栓是同步销(2),从前端驱动壳体上取下同步销(2)和柱塞(1),不要损坏垫圈或取下盖(3)。
2、从同步销(2)上取下垫片,把同步销装入取下柱塞(1)的螺孔里,拧紧同步销(2)。
3、把器端轴转到燃油“开”(ON)位置,直到燃油停止杆(4)的平面与同步销(2)。这就是同步位置或零参考点,喷油器时,把控制连接件固定在这一位置。
4、拆下伐盖。
5、燃油停止杆靠着同步销后,把6V3119齿杆同步表(5)喷油器体和齿杆端之间的喷油器齿杆园面上,用螺丝刀来调节控制杆(6)。转动控制杆上的螺丝,一次一点直到齿杆同步表(5)刚好固定在喷油器体和齿杆端面的凸肩之间。从控制杆(6)上取下螺丝刀,以便在用齿杆同步表(5)检查喷油量时连接件上无压力。当用齿杆同步检查喷油量时,带有螺丝刀的连接件上有任何压力都将使得指示不准确,为连接件处于状态并准确的喷油量,再重新连接件检查喷油量。把9-16或5-8连接板手套在将控制杆(6)和直角杠杆固定在一起的螺帽和螺栓上,拉动控制杆两到三次,然后再检查喷油量。
6、如果必要的话,用齿杆同步表其它喷油器,在进行所有的时,放开调速器端轴。
7、装上伐盖。
8、检查燃油量,必要时进行。对于这一点请参考“喷油量”。
喷油量
需要工具:
6V3139定时和燃油工具组。
5P4814套筒。
6V3075千分表(米制)。
5P7263触点,76.2MM(3.00吋)长。
6V3119齿杆同步表12.7MM(0.50吋)。
喷油量检查
喷渍量就是把燃油螺丝调到规定位置,燃油螺丝通过喷油器齿杆的大行程而柴油机的输出功率。
7. Lubrication hole must be open.
8. Measure pin bushing ID and compare to pin OD to determine oil bance.

9. Insert pin from either side of rod bushing. If pin is free on one end, but tight on the other, the bore could be tapered (A). If pin enters freely from both sides, but is tight in the center, bore is bell mouthed (B).
A—Tapered Bore

拆下凸轮轴
NOTE: It is not necessary to remove cylinder head fromengine for camshaft removal. If push rods arebent or show excessive scuffing, it may benecessary to remove cylinder head for inspectionof block, head and camshaft followers. (SeeREMOVE CYLINDER HEAD in Group 020 or021.)
New service camshafts he fixed gears.Camshaft and gear are replaced as an assembly.
1. Drain engine oil and coolant, if not previously done.
2. Measure valve lift. (See MEASURE VALVE LIFT,earlier in this group).
3. Remove rocker arm assembly and push rods. (SeeREMOVE CYLINDER HEAD in Group 020.)
4. Remove timing gear cover. (See REMOVE TIMINGGEAR COVER, earlier in this group.)
5. Remove cap screws (A) and camshaft activated fuelsupply pump. See REMOVE FUEL SUPPLY PUMP inSection 02, Group 090 of CTM207 (Mechanical FuelSystems), REMOVE FUEL SUPPLY PUMP in Section02, Group 090 of CTM331 (Level 12 Electronic FuelSystems with Stanadyne DE10 Pump) or REMOVEMECHANICAL FUEL TRANSFER PUMP in Section 02,Group 090 of CTM220 (Level 11 Electronic FuelSystems with Denso High Pressure Common Rail).
NOTE: Two-valve head engine shown. Cooling of
four-valve head engine is similar.
The cooling system includes the radiator, coolant
pump (A), and thermostat(s) (I).
Coolant is circulated from the coolant pump into the
coolant passage adapter (B) and circulates around the
oil cooler plates (D). From the oil cooler, coolant flows
into the main coolant gallery (E). From the gallery
coolant flows into the coolant jacket (F), around the
cylinder liners, up through the block deck passages
(G), and into the cylinder head. In the cylinder head,
the coolant flows through passages (H) around the
intake and exhaust ports, valve seats, and injection
nozzles. Coolant flows toward the front end of the
cylinder head and exits through the coolant
manifold-thermostat housing (J). Engines may be
equipped with a dual thermostat assembly (K).
During the warm-up period, thermostat(s) (I) are closed
and coolant is directed through a bypass circuit (L) into
suction side of coolant pump. The coolant continues
circulating through the cylinder block, cylinder head,
and coolant pump to provide a unib and fast
warm-up period.
NOTE: The following test procedure requires that the air
intake be sealed off to pressurize the system.
Using a plastic bag to seal the air intake filter is
used as an example.
CAUTION: Do not start engine during this test
procedure. Plastic bag (or whatever
material-b used to seal intake) can be
sucked into the engine.
exhaust system.
??Rough, irregular exhaust sound, or misfiring.
??Air bubbles, gas trapped in radiator-overflow tank.
??Loss of coolant from overflow.
??Excessive cooling system pressure.
??Coolant overheating.
??Low coolant flow.
??Loss of cab heating (air lock).
4. Shut engine down. Recheck crankcase, radiator, and
overflow tank for any significant differences in fluid
levels, viscosity, or appearance.
5. Compare your observations from above steps with the
diagnostic charts earlier in this group. If diagnostic
buations provide conclusive evidence of combustion
gas, coolant, or oil leakage from head gasket joint, the
cylinder head must be removed for inspection and
repair of gasket joint components.
