Need to replace the piston seals on the bucket cylinder. Current seals are V packings, 3 in one
direction and two in the other. Should I stick with this technology (which seems to be a bit hard to
locate) or go with something else, like a polypack)? IF I find V seals that I can order by bore and
groove size, do they all have the same shape, so they would fit the machined bronze (?) divider
between the two sides? The machine is an old Trojan Model 111 backhoe from Yale and Towne, but I
think the originally seals were even different (O-rings, I think, from the manual). No need to use
the original. Thanks for any advice. By the way, if I turn around the solid backing sections for the
V rings, I get grooves of width 3/8 and 9/16 where I could install new seals other than V rings. (ID
would be 2.75 and OD (bore diameter) 3.5 .)
