I have the same pump as this on Steve was working on so I thought I could revive this topic and see where it went. I pulled the belt off to replace and the pump turns but a bit hard by hand. Don't know but that may be normal out of the water so I would like to be prudent and either put it all together and not fix whats not broken, or look a little deeper.

We may be having a apples and oranges moment.

Here is my pump assembled



This is the pump with the front and back covers removed from the body and impellers removed


This is the front cover with impellers



This is the front cover assembly with the snap ring and spring installed


This is where I am at now.

Awesome, Tim.

Just to make sure I follow:
1. The first picture is the back cover, right? Mine is different. It is just a bushing. What year is your pump? It looks like it is an improved version.
2. What is in the front cover, where the pulley is? Is there a bearing or just a bushing? This is what I am trying to get to. It feels a little crusty.
3. My seal and spring are retained with a snap ring. I have removed the snap ring and spring. Does the seal just pull out the shaft? How do you recommend pulling the seal off the shaft?

Thanks for the help and great pics.

First remove the snap ring on the front, it hold the bearing in place.


I would replace the bearing and the seal kit. You can get the bearing at NAPA, nothing fancy,it's standard, same as a throwout bearing for a car. Take it with you so they can measure it.

This is the order of the seal kit, it will leak if not in the right order. The ceramic piece first.

The hard part is keeping the spring compressed and it not pushing the shaft key out and lining up the impellor at the same time.
