I am about to embark on a very perilous journey. I am going to replace the bearings on my Torsional damper. I realise that some have been fitted backwards and failed and some have been fitted correctly and failed and I have a theory that the ones that were fitted correctly probably filled up with crap and failed prematurely due to this as there was no way for this stuff to be flushed out. So I will be fitting a bearing with NO seals so the oil can flow through it keeping it clean. My other choice is to install a fully sealed pre-greased bearing the same as the one they supply in the kit for the back end. Decisions, decisions!!! Please Chime in Lads.
