Fan wheel on Heater needs to be replaced

[JDJohnson]

I pulled the heater out trying to find out what was making this loud noise and it seems that the fan wheel is very lose. Up and Down motions, don't know what the problem is without taking off the fan wheel itself. But how do you get it off? I'm thinking some kind of fan puller.
Anyone have any thoughts.

What model heater? Photos?

I have two old heaters that I've pulled from mid-70s models. Both have working blowers--the kind with the combined combustion gas and living space blowers.

Pics would help...It also might be the bearings.

Ok I'm trying to figure out how to put the pics on here. Until then here is what i have found out. There was a Hex scew holding the fan onto the shaft, both sides. The shaft itself is loose so it apears i will need a new motor. I am remodeling my airstream and have a LOT of pics and would love to show them off but don't know how yet. The Fan number is 231165 year is 1987 on the cover.

Hi, The model number of the furnace will help. Two sites that may help. Here and here. This thread may help you too. Here

Thank you so very much for the links on how to's. So since I knew I had to fix a wood rot area under the sink I decided to work on the heater at the same time. I can only upload 4 pics at a time so I will start with the floor then move to the heater. Just in case you may won't to see that as well.

Now to the heater, the number on the out side is NT-25/30. the number on the moter is 231165 and it is very loose. It seem it will cost over $200 to replace!
The pic of the motor is blue (sorry about that). Here is the pic of the fan with the hidden hex screw.

Looks like your on the right track. The set screw holds the fan on and the replacement motor for the NT 25/30 K is #231166 and it's $200.00 plus. A new furnace will cost around $500.00 for a new one. Just a thought.

I bought a new motor on ebay for my NT-34 for around $50 plus shipping.

I will replace the motor and put everything back in. I re-stained the wood cabinet and have plans to replace the counter top. I also want to put some stainless steel or something to that effect on the wall around the sink. I am going to try and upload all of my remodeling pic's so everyone can see them. I know from viewing everyones so far they have help me with idea's and making my decisions on what to do. Thanks for the help and idea's ya'll have giving me.

John,
Thanks for starting this thread, and to all the helpful responses from forum members.

I've been lurking with interest. Even though I mostly use my Cat heater, my furnace has been screeching at start up, so a replacement motor looks to be in my future.
