REPLACEMENT linings clutch disc
Disassemble the clutch disc and replace it with the details, except
Friction pads are not recommended. If wear or damage
details of the slave drive
(Excluding wear of working surfaces of friction linings)
loss of elasticity of the spring plate, clutch disc warping (if
it can not be correct), replace it.
In parts a special kit 412-1601954-20 -
two friction linings with rivets, which can be
used to replace defective linings.
In the absence of specific sets of possible, using
as a slave drive guard, drill a new friction
20 holes lining d4, 1 mm, and ten of them (through
one) drilled on the passage to the d8 mm, and then drilled
drill d8, 5 mm with an angle of 140 ° the remaining ten holes
stand the dimensions specified in section B-B (Fig. 71).
To replace worn out or very greasy linings
Perform the following steps.
1.Ostorozhno without hitting a plate spring drive
drill drill d3, 4 mm brass rivets holding the friction
lining to the spring plates of the slave drive, and
Remove the pads.
2.Vnimatelno inspect the spring plate
disk and check for cracks on them, shallow scratches on the
the outer contour and some holes. If there is no defect,
can be made to the disk priklepku new linings.
3.Nalozhite friction pad on the
Spring platter so that the holes in the spring
plates facing the convex side to the attachment, coincided with the
countersunk holes friction lining. Overlay
positioned so that countersunk holes facing outwards
a large diameter.
Brass tubular rivets 4.Vstavte 2 (Fig. 72)
so that their heads were located on the outside of the friction
plates 1 and gently saw off them with a special
mandrel or riveting machine of the spring plates.
5.Sposobom referred to in parxagraph 4, second rivet
friction pad. At the same countersink holes lining one
should coincide with the openings nezenkovannymi another.
6.Posle priklepki both linings check
position of rivet heads, and they should be recessed with respect to
the working surface of not less than 1.0 mm (size a).
In the absence of brass rivets plant production (normals)
They can be manufactured on site (see Fig. 72).
7.Proverte thickness clutch disc assembly with
plates in compression under load 430 kg,
equipartitions on the surface of the pad. Measured on the working
surfaces, friction linings, it must be within
7,1-7,6 mm. The deviation from parallelism of the working surfaces
overlap with the specified load shall noxtexceed 0.18 mm.
End-face run-out 8.Proverte working surfaces
friction linings relative to the driven spline hole
clutch and landing slots at the drive shaft transmission.
To test socket beats a slave drive to put the splined
mandrel (or the input shaft gear.) By rotating the mandrel in the
centers, fix the indicators, the legs are
directly or through intermediate levers come in xcontact with
working surfaces of friction linings slave drive on the extreme
points. General indications for each of the indicators should
be within 0.60 mm.
If the runouxtexceeds 0.60 mm, corresponding to part of the slave drive
straighten the arm with the fork, then recheck
