I'm just trying to do it the lazy way. Lol. Thanks for setting me straight.

 

There's a lot of tension on that cover from all of the oil on the inside. I have a small suction cup that sometimes works. I have also JB welded 2 nails onto the cover (head against the cover) and use nail stems as handles to slowly rotate the cover around and gently pull at the same time. This usually works, but if it's in the truck all the oil in the pump will end up in the valley and still make a mess.

 

Got the pump pulled. And dang u ain't kidding that plate don't want to come out of there. I can get it to rotate with with my finger but no comie outie!! Do u think some grey rtv will have enough holding power to pull it out?

 

I also found the main gasket was leaking a little at the bottom by the ipr and possibly the o'ring where the ipr mounts to the hpop. So I think I had multiple leaks but the o'ring for the back plate was definitely leaking.

 

I doubt grey rtv would bond strong enough. Maybe goop or some stronger adhesive might?

 

Just looking to see what I had laying around. So that plate is in there pretty good then. I used it on the plate over the hpop drive bolt and it was a pita to get off. I had to drive a screwdriver between the plate and the front cover to get it off. I went ahead and tried it since I didn't have anything else. So tomorrow I will pick up some good stuff. But it wa worth a try. We will see tomorrow. Lol

 

Well the plate came right off with this setup

But the issue I'm having is that the old o ring isn't circular. It's flat on one side and pointed on the other. The new o'ring fits in there but doesn't seem like it would seal up very good. I don't have to compress the plate at all in order to get the c-clip on.

 

What did you end up using to bond that rod on there?

 

Grey rtv

From what I have read, my back plate went on way too easy. And there was no chance of the o'ring getting jammed into the c-clip groove.

 

This is just putting the plate in by hand

 

When I just replaced mine (on my old pump) it seemed to be the exact way you described it as well. It went on super easily with the new o-ring and it confused me from everything I read. I don't know if the oil is supposed to soak into the o-ring and expand it, or if something else is amiss.

I couldn't use the pump though because it was the wrong year for my truck, so I sold it on ebay for 180 bucks since it worked well before I pulled it but wasn't sure really the condition otherwise. It's amazing how much of a core charge people ask for rebuilt pumps!

 

My t-500 only has about 20k miles on it. The thing that really throws me off is the shape of the old vs new o'ring. The cross section of the old is a triangle and the new is a circle.

 

I think I recall my old o-ring being a different cross section as well. The new was definitely circular in cross section, but the old did seem different (maybe triangular but I didn't pay too much attention.)

I can only guess that the oil seeps into and swells the o-ring, pressing it up against the housing and plate. Maybe the spot it has to fill is triangular in shape for the cross section. I could be completely wrong though..

 

I'm really hesitant to put this thing back in. Maybe I will email clay at riff raff and see what he says. This just don't seem right.

 

Well I put it back in and no sign of leaking. I guess only time will tell.
