Dead Sewing Machine - Motor Seized

[fossyant]

MrsF's Toyota Oekaki Renaissance quilting machine has died. It flashed of F1 or some such and stopped. The hand wheel just clicked if you turned it - turns out the belt skipped on the motor cog - everything else spins fine.

Under 'can you look at it' instructions (I know nothing about sewing machines), I've managed to split it in two. After pulling to bit's, the motor is exceptionally stiff - tried to free it, but on examination it only runs in bushings,not bearings so is likely to go again.

Finding a spare is difficult, but I've found a similar motor but it's 5500 RPM rather than 6400. Same model bar 1 letter FDM NS(D)70 - I've found a FDM NS 70 (70 being watt).

Same fittings and same little sticky out post for the gear wheel to go on. Will she notice a slight drop in speed. This isn't a normal sewing machine though, it's a freehand quilting machine - Oekaki is 'drawing' in Japanese !

Bet the slower motor wouldn't be noticed.

She doesn't run it at full whack anyway as it's effectively 'drawing a thread' so you take the time.

can you dismantle to motor? Change the brushes, maybe polish up the doofers and generally refurbish it? It's theoretically not hard, I used to do this with starter motors and alternators on my apprenticeship when i was a youngster. dismantle, clean, polish, reassemble.

I did, but the circuit board fell to bits. Mtot ordered, boss not bothered as it's massively 'geared'.

I would try the slower replacement motor and see how your wife gets on with it.

Replacement motor arrived last week, but I was away. Very slightly slower 'apparently' but it's back together and working.

Hardest part was aligning all the tabs on the casing to get it together.

According to a sewing machine shop, Toyota have stopped making Sewing Machines and no longer have a UK parts department.

@fossyant , you're probably aware of this however, there is a specialist sewing machine sop in Heywood. I wouldn't be surprised if they do repairs or could source parts too....

I doubt if the slower speed will make any difference.
I do have some experience in domestic Singer and some industrial machines as well as knitting machinery. Nothing Japanese tho'.

Yeh, we know. They had her Brother £4k machine for 6 months (before covid) awaiting a few small service parts. Hence she didn't want to lose use for months.

It's like faulty e-bikes - you have to wait for 'bits'.

The Toyota is running fine, slightly slower, slightly noisier according to the boss, but it works fine - it's quite a specialist machine though.

The replacement motor just needed 4 washers to space it better, so that the belt drive was aligned perfectly.
