Thoroughly clean the flange of the axle housing.
Apply LOCTITE 5910 sealant on the flange of the axle
housing to form a bead of approx. 5 mm diameter.
It must be uniform (no lumps), without any air bubbles, thin
areas or gaps.
Any flaws must be corrected in as short a time as possible.
Avoid using too much material to seal the joint.
Too much sealant would tend to come out on both sides of
the joint.
After applying the sealant, the joints need to be assembled
immediately (10 - 20 minutes).
To seal at a later date, there is product 21623 capable of
softening or liquefying the above-mentioned sealant.
It is essential to clean the surface to be sealed in order to
achieve good future sealing.
