Bernina 930 Boo Boo
 

My wife has a Bernina Record 930 she inherited from my late cousin. We were putting patterns on quilt squares tonight when my wife told me her Bernina has a slight defect. Patterns #13 and #19 are supposed to be different, but they are the same. It looks like they got two #19 cams in the machine instead of the #13 and #19.

Not that we are going to do anything about it at this late point, but it just show to go ya that anybody can goof.


Also a question for those of you with Berninas. This machine has developed a whistle at low speeds. Sounds like it's coming from the hand wheel end, but it's hard to tell. I'm gonna pop the top off and take a see look tomorrow, but has anyone here had this happen to their 930?

There is a plastic fan on the 930 attached to the motor. You may consider taking off the side rear panel but have caution. The plastic hand wheel is on very tight and interfaces with the drive gear on the main shaft. It interfaces with a screw which attaches to the rear drive gear and secures a washer over the balance wheel engagement spring.

That said, I'm suspecting that the sound is related to the plastic fan wheel on the motor or one of the two belts (notched) are a problem.

Lastly, it may just need to be oiled in the rear area...

Be careful with it, it's very delicate and plastic like...

Interesting. I've not heard of this one before.

I have a Bernina 930- my favorite of all machines I've ever owned. I have never noticed this but will check it out on mine and let you know if yours is just a factory fluke or if others are the same and interesting problem. You may have an original in more ways than one lol.

Dan,

When I cleaned it early last year I didn't remove the hand wheel or the end plate, or the panel on the back. I couldn't figure out how to get it off. And I didn't want to break anything. How do you remove that panel?

Joe

I know this is going to sound like blasphemy but the Bernina Record 930 has way too many plastic gears in it. 4 at least, that I can see. Plus the hand wheel and it's parts are plastic. Yuck. There's also a bunch of little pieces in the linkage and controls that are plastic too.
Nice machine but I'd never pay the prices I've seen after having the top off of this one.

Anywho, here's a question.
Would it hurt to put some Tri-Flow grease on the plastic gears?
There is traces of old grease on them already, so I know they've been greased at least once.


When I cleaned and serviced this machine early last year I think I missed about half the oil spots on it. Either that or they mated and spawned more. :)

You seem to know about the 930 and I have a question. I bought a used machine and cleaned it up. It stitches beautifully, but as you stop the stitching, it has kind of a hard click. Is this normal for this machine?

Triflow is the way to go with the modern plastic machines. Access to the rear requires taking off the hand wheel. Very gently wiggle about 1/8 or less while pulling outwards. VERY GENTLE... The screw that locks the hand wheel protrudes into the plastic of the hand wheel, so too much of a twist will crack the handwheel or deform it. It is a nightmare. Once the handwheel is off, simply remove the screws. Some are under the machine, others are on the rear plastic. DO NOT for force anything. Then carefully remove the rear...it interlocks with the rear panel but will almost fall off once the screw behind the handwheel is removed. PM me if you need more help.

If it's the same "click" my wife's 930 makes it's when the machine raises the needle bar. It does that every time you stop sewing. To lower the bar just press on the heal end of the foot controller.

Dan,
Got your PM and responded.

That is how I figured it would come apart. I didn't try it because I wasn't sure about that plastic ... yuck ... hand wheel. I cleaned it as good as I could with a brush and vacuum then oiled it last night. Much quieter now. And it turns easier. I didn't hear the whistle when I test ran it either. But then again I was sitting off to the side when my wife was sewing with it earlier.

As good as that machine is, gads I hate the plastic bits.
