6.1 Fitting the fast closing clamp Speedy 2 balance Standard
1. Check installation contour for Speedy for dimensional accuracy and surface finish. Important: The
chamfer 1.6 +0.2 x 30° on the ø110 bore must be dimensionally accurate, otherwise the fitting space
for the O-ring will be too small. (Heavy curvature of the cover, the cover will not fit flat) All parts must be
clean, this statement also applies to all supply lines. (Deep bores, etc.)
2. Grease the three O-rings ø4 x 1.5 and place them at the bottom in the locating bores. Note: It is
absolutely necessary to fit the 3 ø4 x 1.5 O-rings and the 3 ø101 1.78 O-rings during the assembly
procedure.
3. Grease all sealing surfaces in the locating bore well and fit them in the correct order in the bore.
Pay attention to the indexing pin position.
Never carry out hammer blows in the locating bore of the SPEEDY otherwise it can damage the
seals. It can also make the SPEEDY burst apart (cup springs are pre-tensioned).
4. Then insert the compression springs with ball cage and retaining ring into the centre bore of the piston.
5. Fit the locking ring into the disc groove. Make sure that the centring diameter surface is not damaged.
6. Tighten fast closing clamp to 10 Nm using the supplied screws DIN 912 M6. Only use the screws
supplied, or screws DIN 912 of quality 10.9. Tighten all 8 screws using torque wrench on the fast
closing clamp.
Note:
To check the flat surface around the cover with a feeler gauge, try to insert it between the
plate and the disc. If it is possible to insert the feeler gauge, remove Speedy according to removal
instructions points 1 – 5 and start again at point 1 of the assembly instructions.
Important:
The ball bearings are loose inside the ball cage. All the balls must be present and able
to move freely. Make sure that the locking ring sits properly.
7. After fitting all SPEEDY devices, apply pressure to the fast closing clamping plate. Refer to the
enclosed instructions for the permitted pressure which may not be exceeded (see Specifications in
Chapter 9)
Important:
Only apply pressure to fast closing clamping plate when it is screwed in position.
Verify the check dimension A on each SPEEDY. Only when the check dimension is reached is the
correct function of the SPEEDY ensured. If the check dimension is not achieved on one or more
SPEEDY devices, the related SPEEDY devices must be removed as described in the removal
instructions points 1– 5.
