Singer Merritt 4525 tension assembly falls out; how do I fix it?

Suggest you oil every tiny hole you can see. Singer machine oil is a light oil, works on any machine. Remove the stitch plate, and oil more. Also, oil the right end of your machine, which could require removing that cover plate. With a small slot-head screwdriver. Just oil Everything! Swing out the ? - access plate on the left, and drip oil into any and everything that moves. Hope this helps.

The service manual for that machine can probably show you, and I would make sure and get the parts list as well. I just checked Sewing Parts Online, and it was not listed, but if you send an email to them (they give the address at the top of the page), they can and will purchase it for you. Usually takes about 2 weeks. However, I just saw a used one in nice shape on eBay for $72.99 and $27 shipping in the original box, so you might consider just buying another one. I also noticed that a new tension assembly is being sold for $18.95 including shipping, and if you write to them, they may include replacement instructions. Just do a search on Singer 4525 on ebay--they have all kinds of bobbins, foot pedals, and parts for it.

There is one for sale on eBay right now for $12.99. http://www.ebay.com/itm/Singer-Merritt-Sewing-Machine-Replacement-Tension-Assembly-Model-2404-/151468509588?pt=LH_DefaultDomain_0&hash=item23443a0994

You will find the parts list most helpful, because it will show you with drawings where each part is supposed to go. Go to the Singer site, and type "parts chart" in the Search box, then select Sewing Machines and the 9 - 900 series. Scroll down; it's towards the bottom.

Remember to have the take up lever down when you start to sew and make sure there is not one piece of thread stuck in the raceway, to access the motor if you have to will mean seperating the body and it is not easy

I found a free instruction manual for the 1872. I can email you a copy.
Let me know!
