Removing motor fan plate, nicely?

[calvin]

Hello!

I've got an old 3/4 GE Motor from a Greenie and I'm trying to figure out how to remove the fan plate. Specifically, if it's screws (without any head) holding the plate on to the motor case or if it's rivets. How I go about removing them relies somewhat on whether I can get a screw in there later.

Picture showing what I want to remove:

If it's rivets I'll just drill the whole thing out and tap the holes for some screws. If it's screws then I'll try to be more gentle.

Any suggestions or insights on how to do this better would absolutely be welcome and appreciated! You guys rock!

is there a hole on the back side of the pins (rivets)?
if there is I would try using a pin punch to remove the pins.

Why do want to remove it? The stator and rotor can be removed by removing the other end cover. I don't see a reason to remove the rivets.

Wow! Lightning fast replies!

Unfortunately there's no hole on the other side so I can't push it through that way, although drilling the holes in there to remove them if they're rivets would be easier than drilling out the rivets (maybe).

I want to remove them because:
- The long threaded rods that hold the motor casing together are trapped under the fan plate in this old model. They're old and I want to replace them.
- Since the threaded rods were trapped under the fan plate, I had a hell of a time getting the nuts on the other side off, so I'd like to make access a little easier for next time.
- The fan plate itself has a lot of rust on the underside I want to clean.

When I rebuilt my Greenie 3/4 horse motor I took off the snap ring that holds the washer, spring, and sheeves on the shaft. In your case, removing the nut would allow you to take the same items off and provide access to the fan and the plate that you are trying to get to. I would not advise taking the rivets out but if you are you will most likely have to grind off the heads, drill out the holes and then tap them for screws all while trying to not crack the aluminum base!

Now you've scared me :P. What I really want to be able to do is remove these pesky rods (without drilling more holes into the face plate...).

My original picture is just one I already had on my phone, below are pictures of the current state of the front of the motor casing:

Do not remove those rivets!!!!

IIWM, I would cut the remaining original original and remove them.

Use all thread and kep nuts on that end.

I am not sure if that will interfere with the fan vanes.

May need to use split washer and thin jam nut????

You beat me to it. That is exactly what I would have said.

Since you got it apart and cleaned the rods look just fine. Well taken care of it should come apart again with no problem. How many times do you think you will have to take it apart in the next 60+ years?

Looks like one came out the hard way.

I guess that one will need to be replaced(?)(if you can't get it straight) but it would be a lot less work to clean up the other ones and get a coating of rust proofing on them and some grease/oil on the threads.

Then the only issue is that one bent one and getting one back in its place but a die grinder might be able to give you some added room to work it back in.

OK, I won't remove the rivets. I had a feeling no one took the fan plate off for very good reasons.

Good points all around, I'm going to preserve the remaining 3 screws that I didn't remove the hard way...

I have replacement screws already so I will just put a new one in there and leave the rest as is. I definitely have a bad habit of forcing my way through something then thinking about it...haha...
