Title: Seal bolt torque.
Post by: Bodd on July 22, 2019, 10:46:21 AM

Does anyone know the torque setting for the seal bolt in the picture, I have a slight weep from one of mine and don't want to over tighten it.

More likely to be the sealing washer damaged than wrong torque

Agrees with Bryan. We have had minor leaks on these on un refurbed engines regularly and it is always the sealing washer that is to blame, not the torque of the nut. Never seen a torque setting for the nut. In fact, thinking about it even my CB550/4 mongrel which has had the engine re built had a weep, so we replaced the washer again then it was all ok. It is a very leak prone area 🙄

Thanks guys, I think I will change the washers and see how it goes, when I rebuilt the engine about 4 years ago I couldn't find the torque setting then either so I used the same as the sump drain bolt.
