needle system question for 111W156 Singer

[bnsmith]

I recently acquired a walking step 111W156, so newbie here.  With the machine I received two sets off needles (pictured).  Can the 111W156 accept both systems (135 X 17 or 134 - 35) with no adjustment ( as from what I can tell there is a ~.9mm difference in length according to spec).

Is there a reason to want to use the 134 system, or would another 135 type work just as well?

Thanks

The 134-35 LR appears to be a leather needle.  This needle system was made for PFAFF.

You can use the 135-16 leather point instead.  Your choice maybe determined by availability and cost. 

Since he supplied both, appears the machine is happy with either, that's my guess.

the 135x16 / 135x17 is slightly longer than 134-35. Depending on how the machine is adjusted it is possible that both needle systems work w/o changing the needle bar height. But I´d recommend the 135x16 / 135x17 needle. Check the manual for the needle bar height and needle Hook timing and set is up as recommend for 135x17 / 135x16 - thats what I would do.

The difference is 0.8mm - see pictures.

The correct needle system for the Singer 111W156 is 135 x 16 for leather and 135 x 17 for fabric. The person might have owned a PFAFF machine or purchased them incorrectly or converted the machine to use needle system 134.

I would pull the needle in the machine and see what is actually in the needle bar. Like @Constabulary check the needle bar height and use needle system 135 x16 or 135 x 17.

@Constabulary Thanks for the pics!   I have not seen those particular ones before.   Could you give the link?   Is there one for 135X16?

What does the pale blue diagram indicate?

I get R and L as Right and Left but what does C and P mean?

 

All

Very hard to tell these needles apart, would the R and LR be easier to spot the difference?

Any ideas on the tolerances + - on setting the needle bar height?  .8 mm is not a lot.   Does the bobbin hook pass the centre off the needle cutout?

Finally what size thread is used with these needles, and would there be a source of samples of thread sizes?   I don't have a good mental picture of what the sizes look like in leather yet (my ultimate goal)

 

Thanks
