How would I install the fan? I have had no luck looking on the internet.

FYI - the parts list showed that the trans or parts needed to come from Tuff Torque. I tried to look it up or find a KB but could not. Some are held on with a nut and some with a spring under them and a snap ring on top. The one caveat someone gave is if it is a nut don't put a lot of stress on the shaft the nut threads onto. Lock the fan and not the trans.

Not familiar with that exact model but if it is like most K46 the pulley above the fan is held on with a snap ring and the fan just slips on the splined shaft. Fans are available for around $40. Just Google "K46 fan"

K46BT IPL is showing a snap ring holding the fan on.

Fan part number is 1A646083070.

Eight serial number breaks for the Husqvarna (HOP) K46BT listed but they all appear to use the same fan setup.

I did remove the locking ring but the fan doesn’t sit low enough to reinstall. I ordered the part number listed but not working.

there is a spring washer under it. Did you compress the fan onto the spring washer?

I didn’t . There’s no give or flexibility after I removed the locking ring. So am I to assume that I compress the fan and then reinstall the locking ring? I soak the area with Blaster Spray hoping that lose it up. This is very frustrating.

So what I would do is first measure the fan thickness to be sure it is the same. Look at the part number on the old one.

I might pull up a little on the shaft with my hand to see if it has any play in it. The parts photo and some articles refer to a spring (wavy) washer under the fan. That would need compressing.

I can't promise you this will work, but I have put on stubborn snap rings on other things by putting them around the shaft, and then sliding a socket over them and tapping the socket lightly. That compresses the washer under it and forces the snap ring down. Without a photo of how far off in thickness you are, it is hard to give a valid answer what the problem is. Be sure the splines are clean and no debris sitting on top of the washer or under it.

all I see in the image is a dirty pulley and a shaft sticking up with a slot for a snap ring. Is the fan under the pulley? What am I supposed to be looking at? FWIW when I take things apart I usually clean them, inspect, ( and maybe paint) before putting them back together. Your photo was so small that I had to blow it up to see it, and that makes it blurry.

Thanks for your input. I have struggled with this replacement and have also reached out to Tuff Torq. Apologies for the photo quality had trouble with file . Basically what I have after removing the snap ring. Appears to be a washer followed by some plastic core around the stem when I removed the snap ring. Wondering if the plastic I’m seeing is the core of the previous fan. Thinking about trying to remove the plastic ring to see if this allows the washer to slide down the shaft so I can install the fan. Thoughts?

I think I’ve removed most of the old fan. Assuming after removing the stop clip the washer would just pull off. The washer is moving at all. I’ve soaked it overnight with WD40 no luck. Very frustrating.
