ok I have a 669eco. The 669 is the best machine in its class in the world. Only Seiko makes a copy of it and it is not as good for about the same price. i can tell you who has the best price on it. You can add a air foot lift to the 669 eco. I have done it and I can walk you thru setting it up. You can use a speed reducer on a 669 eco with a servo motor but cannot add needle positioner because the speed reducer screws with the needle positioner sensors. You can add LED lights to it. I have 2 different lights on the machine. You can sewing bindings with the machine but that means new feet, throat plate and feed dog plus the binder. You can make it a symmetrical feed binder. contact me. glenn

Make sure you under cut the back of the right throat plate over the hook or will not be enough clearance for the thread to pass over the hook. Ifyou can make plates, there are guys looking for them for the 67. glenn

pic please. glenn

You have to grind the sides of the spring down so they do not stick out past the outside diameter of the needle bar. I assume that is what you mean by a lot of sanding. Also file down the grove in the needle bar cut out if here is a thread grove worn in it. glenn

Go to Kwok Hing in Hong Kong. Good feet prices. Hooks check Cerliani and Hirose. Great aftermarket hooks. Adler # is 068-00-181-4. Hirose # is HAD-68. That Hirose hook is on eBay right now for$99.99. Grab it at that price. I have used them for years. Made in Japan. Ceriiani hooks made in Italy. Aftermarket feet are cheap for the 67 Adler. Remember, this is the small bobbin model. The 167 is the big bobbin model. Aftermarket slide plates are out there as well. glenn

nice job. You get the rust off the balance wheel.

Start with pics of set up and items you are sewing please. glenn

Original gears were hard. Try Sitomaco.es in Madrid, Spain. Making aftermarket gears for the 29K1 and a few other parts. glenn

H4 Pfaff 145,545 normally use the needle system #190 which is longer than the 134-35 system. glenn

Pics will help us see it functioning. glenn

How long is the belt and how many cogs are on it? glenn
