The timing was 90 or more degrees off and the hook was worn to a nub. I replaced the hook assembly, and adjusted the timing and all parameters to factory specs.
The Pfaff 145 H3 is a very popular upholstery machine. You won't find anything better than a properly adjusted mechanically sound Pfaff 145.
If you find one make sure it has been gone-over and checked for wear and excessive play, and make sure the hook is still good and timed correctly.
The Pfaff 145 won't let you down, it will sew through numerous layers of leather as well as vinyl or just about anything you through at it.
This wonderful Pfaff 145 now works on any number of items made by Jack Knife Outfitters.
BTW - I got the servo motor for this machine from Nick-O-Sew. NKS-5500.
