What's the proper method of removing the bearing that is pressed into the case for the water pump shaft? I assume you need to remove it to replace the inner seal?

I took the entire cover to the shop. They popped the old stuff out and pressed the new ones in for me. $25 or so for the work. Worth it to me.

i am thinking of making a press out of a very large old socket, the end is wider then the diameter of the bearing. some threaded rod couple of nuts and some washers. then i can use the old bearing to press the new one back in...


Home made press for Water Pump Shaft Bearing.

1 6" 3/8" Standard bolt

4 3/8" hex nuts

4 3/8" x 1=1/2" fender washers

1 32 mm Socket

Popped the bearing out in 30 seconds.

Total cost at Home Depot $1.52 (already had the 32 mm socket)

You're seriously over thinking the matter. Just drive the bearing out with a pin punch by working through the seal. No big deal.

Like GreyRacer513 said, Just drive it out pretty even and you shouldn't have a problem. In general If a bearing has to come out its a good Idea to put a new one back in.
