I think there is a super small pin that holds the latch. See if that is gotten out of the hole that it goes in. You may have to take the bobbin case out to see what is causing the problem. glenn

maximum stich length on 226 I believe is about 5.5MM. glenn

Hoffman Brothers bought the rights and everything else to the to the Pro 2000 from Ferdco. They still manufacture the machine. If it was me, I would set up an appointment at Hoffman Brothers and go look at the machine. Take samples of what you are going to sew to Hoffman Brothers. Bob Kovar does a great job with the Cowboy 4500. You look at both machines and see which is better for you. We are not talking about a $20.00 item here!! glenn

maximum thickness is about 3/8" depending on what you are sewing. not 3/8 veg tan leather mind you but it will sew thru some decent items. We use the machine a lot in the manufacturing of hockey gear. Is it a B, C or D class and is it an H2, 3 or 4. The class tells you how heavy it can handle items. The H is the lift of the presser foot. H2 is 7mm. H3 11mm, H4 is 14mm. glenn

When cleaning it up, should be parts numbers on the parts. That will tell us a lot.

Yes it will handle #138 thread. You have to enlarge the hole in the inner presser foot and the feed dog. I sewed all day long with mine using #138 thread but had to make those modifications. Plus, there is a small tab that holds the bobbin case in place. These machines do not have a bobbin case opener like a vertical hook machine. You have to round the square ends ever so slight on the end of that little finger ever so slightly to allow the thread to pass at both the back and the front of that little finger. I even touched the length of the finger ever so slightly with a dremel and drum sander attachment. That whole procedure allow the thicker thread to pass by it better. glenn

There is a very small spring at the bottom of the post. See if anything got under it by removing the bobbin case and looking at the spring in the small access hole glenn

yep glenn

That machine should have a servo motor on it. The household motor and foot pedal will get burned up over time. Not heavy enough. glenn

great. glenn

You may have to time it in reverse. When reverse lever is engaged, it moves the feed dog. glenn

Julien. please take a short video of your machine and what it is doing. Thank you. glenn

Humm. the foot is not walking at all. I have to look at another video of another machine. This one has got me stomped!! glenn

The Techsew is a clone of the Juki. It has the dial on top for raising the the height of the walk. Both good machines. How much difference in price between the two? I believe the Techsew also has a longer stitch length and higher lift than the Juki but it is a clone!! glenn

Your following gear teeth are chewed up. I have them. Make sure the set screw holding the drive gear onto the shuttle carrier shaft is all the way in. If it sticks out any at all, it will stop the gear from turning. glenn

You have a part number? glenn

It's what applies pressure to the outside foot and will effect the feeding of the material you are sewing. glenn

bar should be remove to determine the length and the diameter of the bar. Consew made a copy of this machine. glenn

Double needle walking foot machine. H3 so 11mm height of foot. 6mm max. stitch length. glenn

The Bell crank made today is for the later 29K models. The one you get today will not fit your machine without a lot of grinding. Just so you know. glenn

Use a sized wrench instead of a crescent wrench. Works better. glenn

I do not use one but it should bring more. If you can get it for $400.00, grab it. My expertise is in sewing machines. glenn

Worth a lot more that. New they can approach $2,000.00. Italian made they were. glenn

give MJ Foley a call and ask for Give MJ Foley a call. Ask for Luke. They were the largest Pfaff dealer in the US at one time, glenn

You want to use a penetrating oil on it. WD40 is not it. The best you can buy Is Kroil Oil. But NOT CHEAP!!! glenn
