Sealing problem on Husqvarna 340

[DaveyCrockett]

I fixed this saw about 15 months ago. It was leaking from the clutch side seal. It had broken the little metal plate that sits over the bearing at the bottom of the barrel. Where the bearing/seal sat the metal of the barrel looked a little shiny unlike the other side which showed the cast finish. The plastic of the shell was maybe a little scuffed but not bad. I fitted new bearings/seals and new little plate. Pressure and Vac tested OK. Job done. Now it's back leaking from around the clutch side seal.

 

I used Loctite grey silicone SI 5660. I didn't put any around the outside of the bearing/seals as there was no sealant there before.

 

Is the way to go to try to reseal with a coating around leaking bearing seal or as it looks like the plastic shell and barrel might now be oversize on the clutch side, is this saw history?

 

As a general enquiry, the sealant I use doesn't seem to bond very tightly. I'm guessing I should be de-greasing the surface and maybe abrading it slightly. What is the best practice to make sure the stick stays stuck?

 

Any advice welcome, Thanks, Crockett
