Permatex #3, aviation gasket sealant.
Only need it on the areas where the ring makes contact with the gear box housing to get a good seal and prevent corrosion.
Thanks for the input on the Permatex although the manual states to use No.2 and not No.3.
What "Manual" are you reading????? Volvo's OEM manuas do NOT recommend Permatex anything,
I apoligize for some misinformation.
On page 44 of the OEM manual it clearly states you need to replace the two Orings on the double bearing box. I had said you didn't need any seals and that was wrong.
It also states on the same page of the OEM manual to use Permatex #3 and it goes on to mention using a locktight on the 4 bolts that hold the ring.
Hope it goes together well for you.![]()
