I have a video housing passed on to me for repair. As part of its overhaul I am replacing all of the shaft seals in the unit ( it had hung around unused and was leaking due to corrosion then destruction of the seal ).
The seals are Quad Rings ( BS010 1/4" ID * 1.78 ).
My current problem involves getting the new quad rings into the groove in the seal body prior to shaft installation. The ring groove is some 1/8" ( 3.2mm ) down inside of the shaft outer and fiddle as I may I am having a hell of a job getting the ring in place. Quad rings by nature do not want to roll at all.
So if anyone has 'been there, done that" I am not too proud to take advise. If I need to make an insertion tool of some type that is no problem, I have a machine shop.
