mechanical seal instalation help

[JEL]

whats the best way to put that water pump mech seal in? thanks

I pretty much destroy the mech seal to get it out. I use a pair of needle nose pliers and rip out the seal so I just have the piece of metal in plain site. I then use a pair of wire cutters and begin to hack the metal piece out by twisting the metal so the seal sort of shrinks onto itself. Once the seal is out I pop out the oil seal and use a comparable size socket to pop the old bearing out.

When I install the new bearing (I grease the bearing outer race and case)I use a comparable size socket and press the bearing in till its flush with the case.For the oil seal I use a over size socket and press the seal in till flush with the case. Before I press in the mechanical seal in place. I grease the outer part of the seal and the case area. I then line up the mech seal and press it in as much as I can with my thumb(not much). Once I know it is fairly level I put the pump shaft in.I use the old seal that was on the impeller and push the impeller on the shaft and get the bolt on and tighten it down until it bottoms out. I then loosen it up and add some washers in back of the nut and tighten it down again until the seal is flush.Once that is done I install grease the new seal for the impeller and press it in and then I apply a liberal amount of grease to the mechanical seal and put it all together.

Thats about it!
