Not saying it is Ideal... But desperation has been the reasons for many new discoveries...Originally Posted by 29232F2F3B420 link=1235086981/0#0 date=1235086981
1: So your using SG to repair the Blue seal ? Pic would be good ;)
As there are a couple of SG types... I never gave it a thought as some are brittle while others have some flex. What type did you use ?
2: I also used a small ball hammer and peened the Group Collar on the one that FL provided... Any panel beaters would also be able to do this with ease. Trick is to take it slow and gental... Not like a bull at a gate... Great minds think alike ( Fitter and Turner - Long time ago).
While not ideal... It did make a significant difference... However as the material has been now worked a bit... It will be interesting to see how well it might last. I was even tempted ( If I can get another OLD collar) to take it to work and see about adding an insert and or looking at some brazing etc to see if I could in fact strengthen / add a hardened section to the main area. Too much stuffing around and not able to be done by most users.....
I get the feeling that the Group Lugs are the main cause as they are stepped rather than tapered like most. Thus instead of a gradule prasure being applied across a larger surface area. The step engauges and then forces its way in, causing a single preassure point that deforms the group collar.
SB should do a recall and provide new PF Heads to all and save on Collar replacement ;D
