The feed dog on my Pfaff Hobbylock 784 broke in half. Are there any replacements?

Lowering feed dogs You can lower the feed dogs by moving the switch at the back of the free arm to the left. Move the switch to the right if you wish to raise the feed dogs. Note: The feed dogs will not raise immediately when the lever is switched. Turn the handwheel one full turn or start sewing to re-engage the feed dogs.

1. Change thread/needle.
2. If the bottom stitch is loose then tighten the top tension. If the bottom appears to be too tight then loosen the top tension.
3. It may help to put the feed dogs down also.

You can also try eBay. If not lucky there, try finagling one using a nail with a drinking straw over the nail to hold the spool.

Hi Dennis, you could try "Sewing Parts Online" (link follows) I don't see you motor listed but if you contact them I'm sure they would be able to find one for you.
Trust this helps, regards Alan
Link --> Pfaff Parts by Model

e-bay has a selection of new motors available for sale
contact a pfaff service agent and see if they are still available. unless the motor smells or smokes I would have the machine serviced as it may be cotton waste wrapped around moving parts that is jamming the machine indicating a failing motor.

see if this link will have what you need

I can't find a manual for this model, however there is a general hobbylock book http://sewingonline.co.uk/library/know-your-pfaff-hobbylock.html which would certainly be a good start.

You may find best source is to contact Pfaff locally and source it from them direct.

You could also try www.diplodocs.com, I can't see this manual but if you go through similar model numbers manuals you may see one very similar. Overlockers/Sergers are very similar in many ways so once you've mastered one, the next one is pretty straight forward. Four tension knobs, 2 needles and 2 loopers is the norm - to get a three thread stitch you just don't thread one of the needles. Tension adjustments alter the stitch formation, and you should have a stitch length knob on the right side of the machine along with a flywheel and if it has it, differential feed (which controls the feed dogs so you can stretch, or compress the fabric as it goes under the foot).

There are some good general how to use a serger books in the marketplace too which should help. Threading up, many machines have a diagram inside the front flap, colour coded dots on the knobs, eyelets and loopers. And oiling points are often marked on this diagram too. But basically oil the two loopers where they slide/move on another metal part. Some good info here too http://sewing.about.com/od/sergersoverlock/Sergers_Overlock_Sewing_Machines.htm

Hope this assists you a little.
