The info that I have seen for the 269 sub class 73 is that it is rated for 130 (#21) needle. Since your machine was converted probably to a 135 x16 system, as the needle that came with the machine is shorter, you will still be limited to roughly a 130 max size needle to provide proper needle to hook clearances.

What is it that you want to sew with what size of thread?

Typical problem when the thread is to large for the needle or their are burrs on the thread guides or needle as well as needle inserted incorrectly.

What size of thread are you using?

How thick is the items you are trying to sew?

138 thread and I’m trying to sew the leather is 6 or 5 mm thick, and fire hose

My take on your sewing woes:

i) The Alder 269-73 can only handle V92 thread with a max 130 needle. So trying to sew thick or tough materiel / leather with the incorrect size needle for the thread is just going to create problems, thread being shredded, skipped stitches, needles breaking, etc.

ii) The needles you showed in the photo are for fabric not leather as denoted by the "R" in the bottom left hand corner of the label. A reference for needle points can be found at: https://www.thethreadexchange.com/miva/merchant.mvc?Screen=CTGY&Category_Code=needle-information#Leather_Points

iii) A good reference chart for thread to needle combinations can be found at https://www.tolindsewmach.com/thread-chart.html

 well thank you very much you helped me a lot

Some of that fire hose is really dense and the rubber liner doesn’t help - you may want to try a silicone lubricant on the thread to help it not get so shredded.   Some machines have a sponge the thread passes over and picks up the lubricant, others have a little pot, and it’s possible to just spray it on the thread spool.

Ok  I don't understand both are the same needle system?  But the needle is not the same length

134 is not the same needle system as 134-35
