What type of loctite do I use to stop the final drive outer racer from spinning in the case please?

638 retaining compound should be ok, but please take advice from your stockest. Selection is dependant on how loose the bearing is, temperature and load. They should have a quick refrence leaflet for selecting the correct product.

Key thing is to get things clean and dry. You will need to clean both surfaces with a solvent like brakekleen or the retaining compount will not work.

Thanks pjjms

Some of the Loctite numbers I see quoted here at times seem to (maybe) differ slightly from those in Oz. You need to use a retaining compound and prep the surfaces using a Loctite Primer product. Be mindful that the bearing has quite some surface area so the Loctite will have no problem preventing the raceway "creep". I suggest you select a low strength grade. Heat will be required on the FD housing if/when you finally need to removed the bearing. Hope this helps, Dennis.
