Hi all.
I'm replacing the bucket ram seals on my 3C3 with a seal kit (Interpart but can't read number) that came with the machine. My ram has a one piece piston head. I've replaced all the seals that came off & I have 2 O rings left over. The thin one is 1 1/2" id & 1 5/8" od, the fat one is 1 5/8 id & 2"od. I am assuming one of them is part no 7 on the diagram for the 2 piece piston head. They are both a bit of a stretch to get over the thread on the end of the piston.
So my question is are these 2 O rings only for the 2 piece piston head & can I put my ram back together without them
