Short Version: I forget which way the outer shaft seal faces on my injection pump and can not find specific info online.
I had thin oil and found out the front seal on my injection pump was shot after a dye test. The machine is new to me so I'm unsure what condition it is truly in.
I ordered the rebuild kit and stripped the pump down, pulled the front seals and realized the seal in my kit was no good, it was too large and was only one seal. I had a twin seal pump. While waiting for the seals to come in I have forgotten the orientation of the seals that I pulled out. Obviously the internal seal has spring facing toward the diesel but I'm unsure of the direction of the outer seal.
Reading online I have found diagrams of a DPA mechanically goverened pump with the seals in tandum and both springs facing internal diesel side but I have also seen a person mention (on a post about a 580C) that the seals should be in "butterfly" orientation with inner seal facing diesel and outer facing oil.
If anyone know for sure, please chime in. I'm about to guess with a 50/50 chance and my track record for 50/50 is that I'm wrong 85% of the time.
Tractor is a Case 580 SE
Pump is a U3042F150 CAV DPA
On a side note, if anyone is also on the HEF, be warned the reset password feature seems to be broken so better write your pass down if it's not an easy one to remember!
Thank for the long read guys!
