Operating Instructions
Removal
1. Refer to the vehicle service manual, and follow the manufacturer's recommended procedure to remove the
strut assembly from the vehicle.
2. Mark the position of the spring in relation to the lower platform and top mount; this notes the correct position
for installation.
3. Choose the lowest possible spring coil to insert into the lower left jaw; hand tighten the locknut. See Fig. 1.
4. Load the opposite side of the same coil in the lower right jaw; hand tighten the locknut.
Note: It may be
necessary to move the compressor arms to access the coil.
5. Choose the highest possible spring coil to insert into the upper left jaw; hand tighten the locknut.
6. Load the opposite side of the same coil in the upper right jaw; hand tighten the locknut.
Note: The bridge accessory is designed to be used with the strut spring compressor on strut springs that
cannot be compressed enough to remove the retaining nut. Refer to the instructions on the next page.
7. Before servicing the strut assembly,
align the strut spring with the forcing screw
on the strut spring
compressor as shown in Figure 1.
8. Equally space the top arms on the top trunnion as shown in
Fig. 2. The forcing screw must be centered between the two
top arms.
9. Operate the actuating screw to compress the spring only until
the strut cartridge is loose in the spring mounts.
IMPORTANT:
It is not necessary to over-compress the spring. The
spring should be compressed only until the strut tube
is loose in the spring.
10. Remove the piston rod nut, and service the strut as required.
Center the
forcing screw
between the
two top arms.
