need to get a bonding compound to seal a vespa main oil seal in - what are people using ?

SIP say Loctite 542 which is thread lock for fine hydraulic/pneumatic threads ?

yamabond 4 - which is the instant gasket ?

Before I never used anything, until I had a problem and after checking my seals I still could not see a problem. But was told if everything else is ok, it must be the seals. So I used gasket paste and put an even bead on the edge and around the front of the seal, hoping that if I blow a seal again it should make it more obvious, this of course only works for the flywheel seal. I did watch that mike brewer program and the mechanic soaked the seal in oil overnight before fitting, saying it gives a far better seal. As for Loctite I hate the stuff, especially on cylinder studs.

I used to use bearing and seal adhesive until I was advised by a well known Vespa tuner to use Yamabond ie Threebond 1104

Cheers Wack I was heading the yamabond 4 or threebond 1194 route just wanted a bit of confirmation

Now to get some - where did you get yours from Wack 63 ?

Search EBay I think it was around £15 to £20 a tube

for anyone who is interested threebond 1104 was replaced 1194 and has just replaced with 1184

just got some direct from threebond/techsil

200g tube with a use by date of end of December 2013 !!
