Replacing the Friction Wheel (Pully) on an Elna Super 62C, timing it, and aligning the needle.

I recorded the process of replacing my friction wheel on an Elna 62C from the 60s. It's my first try doing this. I'm no expert. Lessons learned:
1) Mark all the wires before disconnecting them. I used different numbers of dots on each wire with a sharpie.
2) Be careful with the phenolic piece that holds the light wire away from the motor (I broke mine).
3) The wires must go outside of the timing belt, and be very flush with the housing, otherwise they will buzz against the timing belt. The wire housing plastic also can buzz there.
4) Timing requires aligning and then laying the machine on its side. It's easy to twist the wheel slightly and foul the timing. Also the timing belt pully needs to be snug against its housing, which should be done before timing. The video shows 2 (of 3) attempts before getting it right.
5) The base needs to be aligned to the top when connected back together. The alignment controls the front/back position of the needle. This is shown near the end.
6) Spring clips can jump a long way (easily 20 feet).
7) Don't quit my day job.
I subsequently saw a video where someone claimed that they replaced the wheel without disassembling so much, working just through the main wheel hole. I don't see how you could get the shaft clip off and back on with such limited space and angle. I suppose if you have the right tools and a mirror maybe this would work.
00:00 Disassembly
05:04 Putting on new friction. Begin reassembly.
15:55 Timing attempt 1
18:47 Timing test shows bad timing
19:16 Timing attempt 2 (successful).
20:19 Checking the timing
21:05 Showing bad alignment. Needle is too far forward, hitting the plate occasionally.
21:27 Alignment of bottom assembly to top assembly.

Very useful video! It's given me the confidence to try it now: ) Your simple solution for getting the needle bar height set correctly when timing is particularly useful. I've been guessing it before!

@@billmaney2787 I can do it. I think. Soon find out: ) Love these Elnas.

Hola mi mami tiene una Elna Supermatic pero comienza a coser y minutos después se pone duro el volante y ya no cose que se hace en esos casos

On mine, sometimes the thread in the bobbin area gets tangled and many threads go down there, and then the wheel won't turn. I cut those threads, and then clean out any threads in the bobbin area. I'm not sure why it happens. One thing that helps for me: make sure the threads are positioned away from you when a stitch is started. It also seems to help to thread the little hook/loop that is down and to the right of the tension adjust.

Thank you!! I am trying to repair my late grandmothers 1973 Elna SP 31 sewing machine, which seems be be virtually identical to your model. I fixed the needling timing so it's picking up a thread again following your video, however now that I'm running it I've noticed motor is making a loud buzzing sound when it runs. Any ideas as to the cause that would be greatly appreciated. Video of the issue: kzbin.info/www/bejne/hZWrZn1prbeghbM Sometimes it will run for a few seconds before making the buzzing noise.

Sorry but I don't know. When I saw your comment I was sure it was the timing belt against loose wires but then I watched your vid and I can see that your belt is disengaged. So it can't be that. It definitely sounds like something is loose in there. All I can suggest is to disassemble and wiggle stuff. Good luck

[@tomdenson]

@@UnKnown-fu5zk no worries, thanks I'll give it a shot

You did not show the spring on the friction wheel bracket.

Nice catch. I missed that but showed it later at 6:01.
