Hanging furnace blower motor question

[TT_Vert]

I have an AC motor that i've been limping along for some time. Universal Electric Co. JA2M194N I've disassembled it, cleaned the bushings, etc. but the bushings are just at the end of life. The motor is a 1500RPM 3.3" motor with a 2.25" exposed 5/16" shaft and it spins (Clockwise shaft end (CWSE) I need studs on the shaft side to secure it to its mounting fan shroud which secures it to the housing. This motor (and wires) are exposed and the OE motor has 3/8" flexible conduit as part of the housing to protect the wires. Every motor I've found only has the wires coming out of the motor housing so I have no way to shield them. I'm trying to stay up to code given this are HV wires but I cannot see a way to legally protect these wires. The motors I've found are a D602 and D124 from a company (Universal Electric Motors) that I had inadvertently thought was Universal Electric Co (Maker of the motor). These are both 1/4" shaft motors but I "could" sleeve it if need be or find a 1/4" fan that'd work. They've been very helpful but nothing exact has some up for me. The furnace is made by Modine but the part is unavailable according to their website. Any suggestions on how to either obtain the correct motor OR find a way to shield these wires to code if I go w/ one of these other motors that has no provisions for any conduit would be appreciated.
I did find this but the are saying it pulls 2.4A vs. this one drawing .5A which is find odd.

there was a very recent thread from a poster regarding Modine heaters, his has a cracked heat exchanger.
might be the same motor, he may be willing to part it out.
I'll see if I can find the thread

Modine, Modine what to do?

Back in 2011, I acquired a Modine PD30A0111 off of a CL ad for a couple hundred bucks and installed it in my shop. I have loved having this in my shop. I like the location and I like the feel of the warm air blowing across the shop. Unfortunately, when I was in the shop a couple days before...

Appreciate that, i just sent him a message to see if it's the same. In the meantime I'm open to suggestions from others.

I would try calling Modine rather than trusting what their web site says. If nothing else they might be able to recommend an alternative.

I'm waiting to hear back from them. Their site says they won't sell to anyone but their authorized repair places though so this will likely be fruitless.

1/4" x 5/16 " is a common bushing. This motor is supposed to replace yours. Original motor was made just for heater your not going to find a new motor that uses bx for the wires.

Thank you but the issue with the exposed HV wires still remains the same. I have no way to attach flexible (Or any conduit) to this motor to shield the wires to code. The OE motor has a ****** that 3/8" flexible threads onto. It's also strange that motor is drawing 1.3A vs. the others .5-.8A. On a 110A motor that's another 50W at least. Seems mighty power hungry.

Not sure the speed/power matches but for the wires it wouldn't be hard to bend up something to cover the wires. The motor has studs out the back so you could attach to those (but not cover the motor vents). Then attach a small junction box to convert to metal flex. Took me about 2 minutes with google to find this:
https://www.ktool.net/fasco-kit142-conduit-box-for-3-3-diameter-motor/
Looks like it would fit right over a stud. If not an exact fit maybe drill another hole or add a small plate for more offset.

That is an option if need be. I also found these which go into the square of the motor case where wires come out. I don't like the idea so much but an option. I found a motor which should work, already have a 5/16" shaft so i don't need to buy a sleeve AND has the ****** I need so I don't need those expensive adapter options. It's not exactly the same but I think I can make it work if need be. It draws 250 mA more than the current motor but I don't see that ever being an issue.

So after way too much research I found a motor that is identical w/ the exception of a slightly higher current draw (700mA vs. 500mA of stock) My stock motor listed at 500mA but was testing out at 330mA but it may have been due to the condition of the motor and it not spilling very quickly. Although I would assume that'd increase current draw. Has the ****** for 3/8" greenfield, 5/16" shaft, etc. Cheaper than anything else you'll find also.
