UJF6042 X motor headaches - what is this part?

[btxmedia]

UJF6042 MKI X motor stalled out the other day, got up to 140F degrees and started smoking. Shut it down and I've pulled the motor.

Service manuals say it's actually just an E300532 motor for the JV33 series, same pulley too. In fact M007619 is the JV33 motor with pulley but no one actually has this in stock anywhere.

So I have a spare bare E300532 motor coming tomorrow but no way to get the drat pulley off my burned out motor.

I have drilled out the set screw, and can get the shaft to spin free from the pulley - but now there is some kind of retaining clip holding the shaft in place. I think it's built into the M207793 "TN15-24 pulley" itself? Anyone know how to pull this thing off?

Backup plan is to see if Mimaki will sell just the pulley and set screw to put onto the bare motor.

For some humor the service manual ominously says: "As the fixing screw of the coupling to the X motor shaft is locked, it cannot be removed. Therefore, you cannot remove the X motor BKT. "

Got it working last week. Here are some notes for whoever comes across this:

1. E300532 part number is indeed a bare motor. Despite what some vendors part diagrams label it as - it is a bare JV33 family X motor with no pulley, bracket, etc.
2. The service manual takedown diagram for the 6042 is incorrect. It shows the X motor with what I think is the 3042 assembly bracket on it. I am not 100% on this though.
3. The pulley itself is attached with just a set screw. After removal of set screw you have to extract the pulley. I put it in a vice and tapped/knocked it off.
4. Set screw is easy to strip out. It is a M4 size, 4mm long for replacement. I had to retap the threads after drilling it out. Pulley is soft aluminum so it was a fast rethread.
5. Retaining clip doesn't matter, it stays put for removal and attachment.
6. Set screw has a hairwidth of clearance inside the motor assembly bracket so it can't be more than 4mm long.
7. If you have the parts all ready it's not a hard job to swap it out.
