Stuck Race

While disassembling an MMI pedestal pump that had failed bearings, the outer race from one of the bearings stayed behind in the pump housing. It moved partway out before the bearing disintegrated.

Now I have this race stuck in the housing. It's too narrow to use the wood dowel tool to tap it out (just chews the edge off the dowel) , and I don't want to use a steel drift pin for fear of scarring up the inside of the housing because of the angle required to reach it through the impeller chamber hole.

Any clever suggestions?

Ed, take a large cold chisel and grind an angle punch on it to get into the housing. Might as well try something pretty much nothing to loose.

I don't visualize your situation yet but a slide hammer is one of my go-to bearing pullers. I also have a 3/4-inch brass drift I use when I don't want to mar metal. Perhaps a copper pipe instead of wood(?)

Edward, lots of light taps. Sorta worry it out and be sure it is on something "Solid" to mke the strikes worth while. Keep working around the circle.

May try a bit of heat. I'm not sure but I think the coefficient of expansion is greater in the housing. Worth a try throwing it in the oven before you start tapping.

I have extracted literally hundreds of bearings in my hobbies and work! The hrdest thing for me to learn was that most always it was faster to "fashion" a punch or the pawls on my slide hammer than the knocking out of the bearing.

I worked on old wet cylindrical grinders most all of my life. You have not seen the havoc grinding dust from carbide can create unless you've done it!!!

PS

Edward, the short small diameter is for the seal and a nic or two won't hurt as they can be "smoothed" and a bit of sealant will take care of the rest.

Good luck.

I'm sure my heat gun would be in my tool kit for this job. Put the impeller cavity up, put the heat to the area by the bearing, and it might just drop out.

A lot of great ideas,which I will have to try when we get home. Still just over a week away.

As for the slide hammer/custom tool, are you just envisioning hooks of some sort? No way to get a disk of the correct size above the race.

Would the old bent flat head screwdriver trick work?

Do I understand you've replaced the pump and don't need it for the remainder of the trip?

Ed,

A bit pricey but this is the tool for the job.

Yes. I had the old pump with the bad bearings in my spares locker, and wanted to rebuild it before touching, and possibly screwing up, the working (but leaking ) pump. Alas, I couldn't do it and had to bite the bullet and commit to removing and rebuilding the leaking pump. Fortunately. All went well and it's up and running. Now I'm just trying to have a spare ready for next time!

But if it lets me buy a $122 rebuild kit instead of a $315 pump, I'm still ahead of the game! Besides, it's an excuse to buy a new TOOL!

Don't forget about tool rental.
And the cheapest yet; borrow it.

This Harbor Freight Three-Jaw Pilot Bearing Puller turned out to be the perfect solution. Worked like a champ. And at $19.99, its hard to argue with!

Great find, edwardc. A bearing puller is an incredibly satisfying tool to use in situations like this - especially a cheap one! I would not have guessed HF offered one small enough for this purpose - for $20 this should be considered the job’s standard tool. Forget the bent screwdriver!

I own a large two-arm puller (not HF) for stubborn brake rotors, which, after all curse words have failed, works amazingly to the point of cracking an entire rotor off like a dry cookie. Also, a set of smaller 3-arm HF pullers that a few weeks ago sweet-talked a Vespa’s stuck CVT pulley off its splined shaft like a Sunday walk in the park.
