seal materal type

jim henke · May 27, 2011

I have D47U cat with a Isaacson tracdozer blade asembly that came off of a AC HD 9 that my Dad put on the D4. Does anyone know what type of packing or seals go in the main dozer cylinders where the pushrods come out of the cylinders as there is a packing nut? I assume is it probably like oakem or something like that. the cyl"s work fine other than leaking at the pushrods, have tightend the packing nuts to the point of no more if anyone can help, thank you very much

I would use Teflon (PTFE) impregnated packing. Hydraulic repair (or the Net will find it for you. Jim

Try to find out the name of the cylinder. Then look on the web for a manf. website and see what is put on originally. Some of the cylinder seals on the rod ends have a wiper seal that "wipes" dirt and grime off the rod while retracting.
