A. Removal of the Bushes
(1) Mechanically remove the bush.
(2) Make sure that you do not heat the part on which the bush is installed, you can damage the internal structure of the part because it is made of aluminum alloy.
(3) Clean the part with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a cloth to remove the remaining bonding compound and sealant.
(4) Dry carefully.
(5) Make sure that the surface is clean.

B. Installation of the Bush
(1) Cold-curing with an activator.
(a) Apply Dry lubricant-Anti Seizing PTFE Loaded - (Material No.03QDB1) on the inner side of the bush in order to prevent damage by the sealing compound.
(b) Apply the Adhesive Activator-- Anaerobic - (Material No.05XAB1) on the areas that you must bond and then apply Retaining adhesive-Cylindrical fitting Medium strength - (Material No.05ABE1) .
(c) Rotate the bush to insert it.
(d) The bonded surfaces must not come into contact with your fingers.
(e) Hold the bush in its hole with a tool.
(f) Let cure for 4 hours at 23 deg.C (73.40 deg.F).

(b) Apply the activator Retaining adhesive-Cylindrical fitting Medium strength - (Material No.05ABE1) on the areas that you must bond.
(c) Rotate the bush to insert it.
(d) The bonded surfaces must not come into contact with your fingers.
(e) Hold the bush in its hole with a tool.
(f) Let cure for 4 hours at 84 deg.C (183.20 deg.F) with the thermocouples which are in the bush.

(e) Hold the bush in its hole with a tool.
(f) Let cure for 4 hours at 23 deg.C (73.40 deg.F).
NOTE: Use the activator in less than 2 minutes.
(2) Warm-curing without activator (a) Apply Dry lubricant-Anti Seizing PTFE Loaded - (Material No.03QDB1) on the inner side of the bush in order to prevent damage by the sealing compound.
(b) Apply the activator Retaining adhesive-Cylindrical fitting Medium strength - (Material No.05ABE1) on the areas that you must bond.
(c) Rotate the bush to insert it.
(d) The bonded surfaces must not come into contact with your fingers.
(e) Hold the bush in its hole with a tool.
(f) Let cure for 4 hours at 84 deg.C (183.20 deg.F) with the thermocouples which are in the bush.
C. Application of Protection Sealant
(1) Apply Polysulfide Sealant-General Purpose Fillet - (Material No.06AAB1) on the periphery of the seal between the two parts and use Coating_- Flexible Structure (Material No.04QAB2) to protect the sealant bead in the skydrol areas.
(2) Remove the protection sealant from the inside of the bush with Textile-Lint free Cotton - (Material No.14SBA1) and Non Aqueous Cleaner-General - - (Material No.08BAA9) .
