Found the answer. There is a float with pin which is visible in the site glass. It should be between the two lines. Not something one would notice easily.

Moderators if this is not a good forum for the above machine perhaps you could direct me to a better site. I've found operator and parts manuals that are similar but don't have much information on oil levels. There is a site glass but it is not possible to fill to that level as there is a screened opening on the bottom sump and oil pours out. There is no other method such as a port or dipstick to determine the oil level. If anyone should have information relating to this machine would be much appreciated. TIA

another long shot as this is an old thread and all search turned up. If this posting should be in another location please move. Siruba737D 3 thread serger. Found a service manual. Was in process of replacing oil..The manual does not state the volume of oil. Oil is supposed to be at mid points of the sight glass. Added almost three liters and not showing yet. Suddenly oil was leaking fro I don't know where. Anyone happen to know what the volume should be? If I can find where the leak is and repair. Thanks

More searching turned up this site. Much better pictures. The clamp is slightly different but there should be a screw above the needle. https://manuals.plus/m/8974fd3aa9b86a5fea8798493b21b4c3a490257fbfff0ff8d94fe6d110343e8b

Anyone familiar with the needle clamp on this machine? I believe there should be a screw in the bar to limit the maximum depth of the needle when inserted. Also I'm suspicious the clamp screw is not correct for this machine. It's brass and will tighten and hold the needle but the threads don't appear to match well when observed with naked eye. Obviously someone has worked on this machine previously. The check spring was mangled to begin with but we now have that functioning. The setscrew to adjust the needle bar height is mangled as well. Hopefully we can find one. I found a Nakajima 280-L parts diagram but it's not very clear unfortunately. TIA

Yes working fine now. Never did get a response from Reliable. Found the You Tube video by accident. It shows a clear picture of the connector.

Found a YouTube: 4:52 mark. So the machine is now working.

Left an email just after posting here but so far no response. Sent a service request today.

Three wires of the four wire connector which plugs into the rear of the motor have been pulled out. Only the blue wire is still fastened. Anyone have a similar setup?

No it's not a lie. It is still single phase. This guy has it right.

OK! Got the machine to sew. Came with two bobbin cases but missing two screws and for certain one screw is too long but they do enter so it does give lower thread tension. Followed a video found here on how to remove the hook assembly. Thought I should inspect. Wouldn't believe the amount of thread wrapped down under!! Cleaned all the parts, oiled and it sews. Hopefully all that's needed now are proper bobbin tension screws. Would be metric of course but wonder what size?

Ooops. another Google turned up a manual. I'll work with that for now.

In need of bobbin tension screws. (in Canada preferred) Also hoping to find a D/l able service manual. Thanks

Thanks. All I can find so far is this: https://simards.com/ They have closed shop just recently. I have a table, though the cutout may not match. Spare clutch motor laying around and can make or scrounge up the other parts needed. Current bid is $2. There are several other industrial machines on this sale too, a Pfaff, Singer, Adler and some leather. Close out (not connected to Simard's closing), retirement or estate sale perhaps???

This unit on auction locally. What can the group tell me about it? Haven't examined it yet but presumably it's functioning. No table. BTW, serial 2895

Well I'm wrong the set screws are indeed 1/4 x 20 TPI. I finally took gear off to get a good look at the threads.

In need of a tension screw for the bobbin case on this machine. It sews as is but it needs to be replaced. Suggestions appreciated. Also discovered the two original locking set screws on the hook driving shaft pulley are missing. Someone replaced with an standard 1/4 x 20 TPI set screw which is NOT correct thread. My measurements are 1/4 x 24 TPI. Project for today is machining screws. That's doable but not attempting a tension screw. These old eyes can barely see those tiny screws. Oh also the felt oiling pad is missing on the bobbin case.

Thanks very much. Just found a couple minor problems with this machine.

I realize this is an old thread but has anyone found a more readable copy of the service manual? The one floating the web rough indeed.

I notice that bobbin tension is essentially zero. No amount of adjustment on the screw changes tension. One bobbin case is ever so slightly better but the other, nothing. Removed and clean the debris but that didn't help. I suspect the spring is distorted but am afraid to try shaping it. Anyway It seems to be sewing OK for the moment.

Thank you for the reply. That search does not work on my computer, however it did work for my cell phone after following your link. Interesting. This my first glimpse of a multi needle machine. Yes I noticed immediately that the left hook turns the opposite direction. There is a perfectly good reason for that. That allows use in design of many of the same parts from the right side. If both were to turn the same direction the left side parts would have to be a mirror image of the right side! Under corrective measures it references (See xx-x in the SEPARATE INSTRUCTION BOOK. Wonder where to find that?

Anyone know where to get a shop manual? Can't even find an operator's manual. I'm wondering is there is a problem here? The machine is not stitching well at times. Notice the difference in the position of the fingers next to the bobbin cases? The right side is barely catching. It appears to be rotated away from the hook and bobbin case. I haven't yet checked underneath for any way to adjust these fingers. By loosening the screw the finger could be moved forward or backward but not rotated and both seem to very similarly positioned in that respect. I looked at the timing of the hooks and each is above the eye in the needle similar to all domestic machines so it appears that is OK. Any suggestions or help appreciated.
