I started to replace the seal in the car yesterday. I got that top stubborn bolt off after I removed (and cleaned) the fitting for the injector line. Notice where the bolt is.
Then I got the bottom with a very tight Torx bit. Worked great. Went inside to eat dinner and returned to see tragedy had set in. I thought it was going to take some force getting them apart, but the several days of WD-40 let gravity separate them without Andrew's bolt being tightened as required to keep everything in place.
I thought I could get it back together if I carefully pushed them together, so I tightened Andrew's bolt, and them the two new bolts until the seal was just exposed by 1 - 2mm... I tried to peal off the old o-ring, but it was partially fused to the housing from the heat of over heating... There was on piece that was on the back side of the housing where it was impossible to remove it and have a clean groove for the new seal.. so I had to remove the body anyway. Once appear, there was no way to just put it back together...
So, on to resealing a spare pump that was pulled from a running engine. I cleaned it inside and out first. Looks really good inside.
Since it looked so good inside, I decided to only replace the top seal, the body - body seal, and the shaft seal with Viton seals. Someone posted on the net how to do the body seal using gravity to hold everything in place... I also used Andrew's bolt and it worked great !
I was amazed how much the o-ring would stretch. It looked perfect before closing.
Getting the old shaft seal out was a pain
But the new one went in w/o issue.
Next was the process of swapping pumps and retiming. MAN did I dodge the bullet on that belt not tracking right !! I got the top 2 IP bolts off but the bottom one is becoming hard to get at. Looks like I might have to remove the alternator & A/C mounts to get at the bottom bold.
