My Shadow motor is coming together nicely now.I am contemplating barrel and head fitment,and the pushrod tubes are being replaced with a set of Maughans solid turned stainless items.Very nice too-substantial.
What is the accepted wisdom as regards seals? I have the standard items ET123 upper and ET104 lower.
Certainly, the upper seal seems OK, and with the rigidity/quality of the new tubes,only one washer atop the flange seems sufficient-is there any need for a second one under the flange on top of the nut (or room-given the thickness of the Spares Co. ET123`s)?
Perhaps more importantly, the bottom seal ET104, it seems, cannot be removed without lifting the head? Thus, I want to get this one right first time- the standard hydraulic type seal seems to fit OK, but I have heard mutterings that a tight O`ring is better......which works best? All advice greatly appreciated, Regards, Bob.
