Where could I get a back looper for a Riccar rl-924dr

try changing the needle
check to make sure the top thread tension is not to tight
check to make sure the thread is not caught somewhere
change the thread
clean under the needle plate & in the bobbin area for loose threads or lint

Sounds like a threading problem. Thread the machine all the way to the needle but not the needle eye. Then pull on the thread and lift the presser foot up and down. You should have tension when it is down and no tension when it is up. If this is the case try sewing, should fix the problem. If this is not the case your machine will need to be adjusted buy your pfaff dealer.
Hope this helps

HI
Try finding a threading diagram in a manual for another riccar machine here.

I couldn't see a manual here for the Riccar Reliant 57 but there are ones for the RL570 etc.
Most machines by the same brand thread in the same way.
Hope this helps!

Have you tried the Riccar site?

I couldn't find one for your specific model number.
Have a look at a few of the manuals with similar model numbers. Or try to find a manual that most closely resembles your machine.
Usually sewing machines by the same brand are very similar and thread the same way etc.
Hope this helps!

Very unlikely you will get a manual for a Riccar, the only place with any hope would be www.sewusa.com

Generally caused by lack of tension on the upper thread. Thread machine normally and pull the needle thread sideways from the needle with the presser foot up. It should pull smoothly. Lower the presser foot and it should become hard to pull and the needle will bend. If this doesn't happen, the upper thread is not in the tension assembly and you should rethread properly. Also, make sure thread is in the take up lever that moves up and down on the front of the machine while sewing.
