[QUOTE="Tom Gaynor, post: 2237, member: 4034"] [b]Zeppelins[/b] It saved me a lot of grief because i had bought a mainshaft seal and realised two things before I attempted to fit it. Firstly, the seal would cure the symptom, not the disease (thank you, HM and Prof), and secondly (thank you, Trevor Southwell) the contact between ESA and main bearing inner is already pretty narrow, and a seal makes it narrower still. So the ESA wears, the chain become misaligned, the chain snaps bursting the chaincase, all just as a truck carrying an entire class of schoolchildren and laden with nuclear waste comes round the corner overtaking a petrol tanker.............. I made some of that up, but if you do use a seal it's a point to check. However, the answer is to sort out the breathing when the self-filling chaincase / gearbox problem goes away. [/QUOTE]
