Consew 226R1 going opposite directions of controls

[marscstars]

HI!

I have a Consew 226R1 and have sewn for years on it or similar equipment, so I am not a rookie.  But that being said, I am feeling like a complete rookie right now.  I oiled the machine really well as it had been sitting for quite a while.  Then I checked the threading, bobbin was wound tightly, hand wheeled the needle thread to bring up bobbin thread, ready to go.

So when I depressed the food pedal to walk a couple stitches forward, the machine went backwards.  So I realigned and tried again, and I went backwards again, however if I use the reverse paddle it moves forward.  So I looked through the little manual I had, and tried to reset the clutch, thinking that may be the problem.  But the little inner button and rotating of the wheel manually away from myself did nothing.  It won't engage, or drop deep enough to let me reset it as it did back in the day.

I have power cleaned underneath, took the bobbin and hook off to see if there was anything stuck in there.  I reoiled it again, and my feed dogs are still going the wrong way when I move the wheel manually.  I am lost on what to do next, any suggestions? Thanks

Check your motor to see if it accidentally got set to rotate the wrong way. This recently happened to another member.

@Wizcrafts  I had to read the OP a few times to get through my head what was happening here, and to see if it might be the motor as you pointed out in another thread. 

Not being much of an expert on adjusting machines, I get myself in trouble now and then.  I was helping someone with a domestic machine making an adjustment to the feed dogs, and suddenly they were feeding backwards. Finally got them heading the right way again but seemed to have really short stitches.  Later I tried to help with the machine again as it now wouldn't feed at all.  One of the clamps on the linkage that drives the feed dogs had cracked on the opposite side to the screw, so would not keep any adjustment.  So being an older Brother domestic, it went in the garbage. 

Anyhow, my take on this would be the feed dogs are misadjusted since it happens when hand wheeled and by motor.

Check page 8 of the manual and see if your relative height of presser feet and timing of vibrating presser foot is correct. That cam inside there (V, Fig 6) is easy to get wrong IMO and if a screw gets loose or someone fiddles with it feet can walk backwards yet everything else appears correct like timing belt and such.

So question is, are the feed dogs going backwards, or the walking feed going backwards?

If the feet are going the right direction, then need to go back to the feed dogs as the OP first commented.

If the cam is set wrong the feet go backwards and the feed goes forwards - the wrong way. I have seen it twice and fixed it twice. On a 168g101 the cam was improperly adjusted and left loose. It fell off the saddle it sits and spun loose on shaft. On a 153k103 it wasnt like that just set 150-180 degrees off. Point is that on the 153 someone had also just set the timing marks off to compensate for the improper adjustment up top at the cam. It looked OK except the vibrating presser foot timing was off. 

This may be the issue or not. I dont think the feed dog fork assembly below can come loose and make the dogs go wrong way but I could be wrong since it does ride on an eccentric dealio on the main shaft. Timing would have to be off to have the feed dog eccentric flipped wrong IMO.

The issue may also have to do with synchronization of the bottom hook driving shaft. If the safety clutch is not cooperating, it may have slipped and rotated the bottom shaft out of place. You really should get the safety clutch working again. Otherwise the bottom shaft may rotate out of position randomly as you sew and create all manner of trouble. The safety clutch not only prevents damage when it disengages,  but it also locks in the proper hook and feed timing when it’s engaged. If the bottom shaft is rotated out of position by 180 degrees, then the  feed motion will be exactly opposite of what it should be.

A quick visual check to confirm proper feed synchronisation to is rotate the hand wheel to bring the thread take-up lever to the very top position. In this position the feed dog should be at the very front of its motion. If it’s not, then the bottom shaft is not properly synchronized.

This video shows how you can pop and reset the safety clutch in case the reset button is not working:

This video goes over the safety clutch mechanism in some detail, in case you need to service it:

 

Lastly, a video that shows how to synchronize the drive belt and bottom shaft (this video only make sense if the safety clutch is already in the correct, engaged position.)
