Fitting Superflex Bushes
- Remove all dust, previous bush residue, paint and old grease
from contact surfaces prior to fitment.
- Ensure any original outer shell is not inadvertently left
in place. A common mistake where the old rubber bush has unbonded
from its shell. In some instances the outer shell is intentionally
left in place. This is explained where necessary in our online
shop.
- Do not fit new bushes to worn, rusty, or distorted fittings.
Worn components must be replaced.
- Lightly coat bush contact surfaces with assembly lubricant
(where supplied) prior to fitment.
- Insert the stainless steel tubes (where applicable) after
the bushes are installed into their housing.
- Immersing high-interference fit bushes in boiling water,
can assist fitting in a very cold climate.
- Before the final tightening, suspension arms must be at
normal ride height.
- When replacing original componentry, ensure that all nuts
and bolts are tightened to original manufacturers specifications.
- Bushes must not come into contact with alcohol-based solvents
such as MEK, methanol, or methylated spirit.
Using Original Outer Shell
If the Superflex bush re-uses the original outer shell,
the OE rubber bush must be removed by the following procedure.
This procedure applies to the following Superflex bushes
: SPF0276, SPF1005, SPF1312, SPF0638, SPF1104, SPF0807K,
SPF0767, SPF0234K, SPF0235K, SPF1940, SPF1411.
Note: This procedure must be carried out in a well ventilated
area.
- Use an oxy-acetylene torch or blowlamp to warm the outer
shell, this will destroy the bond between the rubber and
the shell. The rubber bush can then be removed.
- Further heating can be used to removed any remaining
rubber from inside the shell. Use a wire brush and emery
paper to finish cleaning the inside of the shell.
- Using supplied assembly lubricant, grease the inside
of the shell and the outside of the polyurethane bush
then, with the aid of a vice, clamp, drawbolt or small
press, push the bush into the steel shell.
- Grease the inside of the polyurethane bush and the outside
of the crush tube (which the bolt fits through). Then
press the crush tube into the centre of the polyurethane
bush.
- The assembled bush can now be fitted to the vehicle.
Note: The original centre crush tube is required for SPF0807K,
SPF0767, SPF0234K & SPF0235K.
