Removal and installation
3-2
Installation of the single-axle spring
assembly
1.
Thoroughly clean and check the spring
buffer and shackle bush. If necessary,
replace. Check that all contact faces are
free of dirt, grease and paint. Tighten the
centre bolt and the spring clamp bolts.
2.
Install the wedges and filler blocks (if
applicable), in the correct position. When
installing the spring assembly to the axle,
check that the centre bolt is correctly
positioned in the appropriate recess.
3.
When reusing the U-bolts, check for
corrosion and damage. If necessary,
replace. If they are to be re-used,
thoroughly clean the thread and remove
any paint.
Tighten the U-bolts provisionally. Do not
forget the hardened steel washers.
4.
Before installation, thoroughly clean the
shackle pins and shackle bushes.
Apply lubrication grease to the shackle pins,
shackle bushes and shackle-bush sealing
rings.
5.
Fit the shackle pin in the correct position
(lubricating nipples on the correct side).
Take care not to damage the sealing rings
and washers in the process.
6.
Fit a steel ring on either side of the spring.
In the event of play between the side of the
spring and the spring bracket, oversized
washers must be inserted. For the
oversizes available, see the main group
“Technical Data”.
If possible, to the left and right of the spring
(or of the spring shackle) fit washers of the
same thickness.
7.
Lower the chassis until the shackle pin (2)
just touches the spring bracket (1), but can
still be rotated. Then rotate the shackle pin
until its flat side is parallel with the bottom
of the spring bracket.
8.
Secure the lock plates (3) with the locking
bolts (4). The lock plates (3) should rest
against the flat side of the shackle pin (2).
