REPLACEMENT support feet
Support Heel 7 compression spring 5 is held in assembled
position by a spring-conical ring 12
and the central hub 11, which after installing a retaining
slots in the heel compression spring is inserted fully into the shoulder
the internal diameter of the heel and zakernena in six places by
pressing the central hub 11 in the radial direction in the
groove on the inner surface of the heel. Conical spring
ring 12 due to its elasticity selects the axial clearance after
Build heel to push the spring, and compensates
defined within the wear of the surfaces of these parts in
When a significant wear, which is not
compensated by the elasticity of the conical spring ring
or when the last vacation due to a significant heating
working surface of the heel due to violations of operating rules
the car is loosening the heel. When starting
off and the car on track when working clutch appears
characteristic rattle and knock at the site.
To replace worn heels, remove the center bearing bushing
fixing the heel, as shown in Fig. 58, the deformed flange
a central hub with a hammer and chisel 2.
To prevent damage during removal of the supporting sleeve
feet and other parts of clutch recommended
place the heel of the supporting mandrel locking repair
tool, just as shown in Fig. 59, the base
which must be securely held in a vise.
If there is a lathe cut the thrust flange of the central
bush cutter. To install the new bearing heel offers
prepare and implement a set of maintenance tools (Fig. 61).
After removal of the worn surface of the heel look levers
compression spring in xcontact with the fifth. If, after stripping
worn surfaces of the ends of the levers compression spring dimensions
noxtexceed indicated in Fig. 60, the spring can be used
to build a new base heel. Check also
the height of the conical spring ring 12 (see Fig. 57), which
in a free state should be in the range 2.5-2.8 mm. At
at a height appropriate to replace the new ring.
Dimensions and data for material and heat treatment of parts that make
in the scope of the above tools are shown in Fig. 62.
Before replacing the supporting heel, make sure that all parts
used the repair tool and collected details of the
traction rather clean.
The installation of the supporting heel make in the following sequence:
1.Zazhmite in the grip of the base repair tool with locking
mandrel (see Fig. 59).
2.Pomestite supporting workers' heel flat butt down in the fixing
mandrel repair tool. Brush with a thin layer of grease LSZ-15
countertops tip levers compression spring, and set
mechanism of adhesion to the supporting heel so that the working surface
pressure plate facing up.
This should ensure that the compression spring levers
located between the protrusions on the surface of the radiused heel.
3.Set conical spring ring 2 (Fig. 63) concave
side to push the spring, and cover it with a central flange
a sleeve, inserting the latter into the hole compression spring.
4.Vvernite a guide (Fig. 64) for the base zakernivaniya
adaptation to failure, pressing the central hub to lock in
end flange of the supporting heel.
5.C using a core (Fig. 65) zakernite central hub 2
groove on the inner surface of the heel support six uniformly
located around the circumference of the field. When zakernivanii
Cairn keep as closely as possible at an angle of 30 ° to the horizontal, as
shown in Fig. 65. The flat part of the core of this should
build on the site guide.
