I was thinking about using epoxy as I used it on an exhaust before and it sealed well.

give clear silicone(fish tank quality) a go, you'll find it does the job well...no problems getting it off should you need to. I've used it for exhaust gaskets on 2 stokes...last I bought was £5.00 for a small tube

15193314268391737277795.jpgWell after a good wait I got what I needed. I looked around loctites site maybe I was on the wrong part of it or wrong site but they had very poor descriptions for the wide variety of choice between there products. I ended up going to buy 620 but after being on ebay found 641. I was looking at 574 sealant but the price and the fact the 595 says it is flexible and also your recommendation Jon I went for the 595.

I was wondering about the sealer and thought is it better to put it on and just torque it up straight away or should I partially torque it till it just starts to set then torque it right up ? I was going to take the inner seal off the bearing but was wondering what your recommendation for that would be Jon as I have removed factory fitted bearings off a few engines that had both seals fitted.

I have used the original orange RTVR to good effect but only because as a mechanic I had it on stock. However I have also used very cheap clear silicone. I run as thin as I can a bead of silicone and spread it to a thin layer.I wait . a minute or two until the layer gets a film on it .I then screw it up until it starts to squeeze out then wait a few minutes more . Then tighten down.Doing it this way reduces chances of blobs forming inside then breaking off and rolling round and maybe causing probs inside. Not very likely at this size but on full size these blobs could block an oil way. Clean off any oozed stuff with a sharp blade. Job jobbed.You now should have a perfect seal that will last. Any silicone should do but if you can get an industrial, mechanics, or even a glass sealant type ( aquarium seal ) so much the better. They are usually a bit stronger and don't be impatient. Allow time for the initial setting to take place as even if the even if the softer bit squeezes out the SKINS will remain as the seal. Good luck.
