What size is the bolt that holds fan blade on Coleman Mach 15 AC blower motor?

[TXfreeze]

I'm replacing the.blower motor on the AC, I've watched a couple videos on YouTube but they don't say what size wrench to us to remove the fan blade e one said you need a 5/30 I have a 5/32 but it looks.more like a Torx to.me, I just want to get the darned thing.off anyone know what I need to loosen it? Thanks

Im not trying to be a smart a** with this quest but If you have to get it off why not just get up there and pull the cover off to find out?

Ah come on! Why not take a small tool pouch up and get it off on the first run??

No worries, I've already got the cover off. I'm all set to.replace the motor with a new one but I can't budge that one screw. If I can't take the fan blade off I can't race the motor, I may have no choice but to extract it and replace it with a.machine screw, if I can't figure out which is the suitable tool.to remove it with.

I've tried various Allen hex wrenches and sockets no go, might be stripped might need to extract..

I’m not positive but the threads my be left hand

So. they are left hand hex screws not torx? Thing is in the video here , at 1:30 it's really hard to tell so I slowed it down to 1/2 speed so I can see and it appears he's turning the wrench to the left? If they are left hand screws than wouldn't it be to the right to loosen?

Try a torx wrench. A T30 is a size and Allan wrenches are in inch or metric that 5/30 leads me to believe it is not Allan

5/30 is what the guy on the video said he had and he said it was an Allen, maybe he was confused, what I've tried is a 5/32 Allen. Well I don't have a torx wrench I need to get one, I was just watching a extraction video and if it's a stripped hex head it could be extracted with a torx just have to hammer it in, upon further observation it indeed looks like it's a stripped hex, I think it was already stripped because when I put the hex wrench it it wouldn't catch at any rate looks like i need torx either way. I don't think an easy out extractor is going to work and I don't have any bolt extractors need to get those too, I also need to figure out what bolt I will replace it with although at the moment I will have to temporarily use the bolt screw I have till I can get a replacement. Turns out I have Torx in my socket set I tried T30 it's too big I'm going to try the hammer trick see if that works.

My favorite bolt extractor is a left hand drill bit.

I would like to.report the replacement is done, I would like to but that's further from the truth, the truth is I finally found a Torx bit that was right under my nose in a compartment on the top of my toolbox, when I found it I just knew it would fit and sure enough it did and the shaft collar is now loosened. Now if anyone tells you its easy to remove the fan blade off a rusted motor shaft. they either haven't had to remove it or are lying, I can't get the dammned thing off, I've sprayed penetrating oil, WD40 silicon it won't budge an inch, I've tried gentle side to side motion like the video said prying, pushing, pulling, hammering nothing ,its like there is a clip or something in front of it holding it in. My only option now is to cut the shaft off so at least I can get the motor and fan out, try go get it off on a work bench, worse case scenario I need to replace the fan blade.

Try blast off maybe freeze off,seems to work in many cases.

Coincidentally bought some blaster Multi Max at Wal-Mart yesterday ill give it a shot. I searched Freeze Off only coming up as a skin tag remover remover, so I take it actually freezing it , is that done with dry ice?

Thanks ill keep it mind for the future, Well nothing budged it so I wound up cutting its just as well because all the pounding cracked part of the fan, I found a replacement on Amazon, thats the least of my problem, I went to mount the new motor and accept for where the motor screws for the lower support stand goes not one of the damned mount screws aligns with the mount plate, I either don't have the right motor although its rated and wired the same, its a bit wider,.also like in one of the videos I had to reverse the 3 screw on the motor so it mounts from the front. looks like I'm going to have to drill 3 new holes in the plate keeping the shaft centered is the problem since I don't have a work bench to work on it, what would you do?

I’ve replaced fam motors on (2) of (3) units. It is a torx 30 , conventional lefty loosey. Hold the blade and use a drill or impact driver with a torx bit. A set of torx bits will always come in handy.

Evap fan was a t handle allen for the longer length reaching through the fan. The condenser fan blade was a clamp with a sheet metal screw through the clamp. The Allen was either 9/64 or 5/32. I found the evap fan blade was not close enough to the evaporator and was drawing air around the side of the blade instead of the evaporator. Make sure when you put the fan blade back on that it is as close to the evaporator as it can be without rubbing on the Styrofoam.
