Made good progress with the machine, it's running really smooth now so I'm guessing there was just a sticky join between any number of parts that are now fully lubricated. I still haven't had any progress with matching the stitch length. I've got the feed dog movement central and no movement on the feed dog when the needle is at the lowest point so my next step is uncertain. Was going to put on a Reliable 6050sm Servo motor but the shipping to Aus is too dear to justify it unfortunately! So this is one of my local options (http://www.ebay.com.au/itm/New-750W-Variable-Speed-Servo-Motor-for-Industrial-Sewing-Machines-/221873671944?hash=item33a8b38f08:g:NigAAOSwpDdVUqHd) hard to know but I think it'll be worthwhile.

Thanks. I've ended up with a standard lithium grease (lithium 12-hydroxy stearate) just because of availability. There's only one screw I haven't been able to crack at this stage and that's for the adjustment of the needle bar to enter centrally into the throat plate. I don't think it's been undone since manufactured and the needle bar is a fair way out so am going to have to buy one of those t handle allen keys to get it I think. Hard to know where to draw the line once you start taking things apart haha...are all the concentric and shaft type joints just lubricated with oil? I'm tempted to take them all apart as there is a moderate amount of gunk that has accumulated around them which makes me question the state of the internal faces.

I couldn't find anywhere in the manual about the type of grease to use on the two cogs underneath the bobbin assembly. Mine was looking very mucky, black and thick and I'm assuming that's wear and not the intended product?

Ahhh Uwe I have to admit I was hoping you might chime in as I've learned so much from your other posts! Thanks for spring pressure and other tips, ill get investigating.

Hi all, I'm an upholsterer and have recently acquired an Adler 267-gk-373. I've only ever lurked here and never posted but I have learned quite a deal from some of your more experienced and consistent contributors. The issue I am having has however drawn me out of the shadows. I have not been able to make any progress with finding out a couple of things for the Adler. First, the video: Second, I have no idea where to start looking for the increased 'pressure/tightness' on the bottom portion of the needle bar stroke. I haven't encountered anything similar to this before. Third, the stitch length doesn't match the markings on the cast iron casing. Fourth, the reverse stitch doesn't match the forward stitch in length. If anyone can help solve these I will put in a good word with Santa for you for this year lol.
