Singer 111W155 Cracked Upper Arm

[oldskoolbob]

Hi,

My name is Bob I'm new to Leatherworker.net.

I picked up a Singer 111W155 as is machine for a very parts machine price.

It needs a timing belt and the previous owner could not get the handwheel off.

I managed to remove it (not easy). Now the bearing assembly is just as stuck.

I'm soaking everything in Liquid Wrench and waiting.

While cleaning and oiling this machine. I noticed some hairline cracks in the upper arm.

The arm is still quite rigid. Did these cracks happen in these old machines?

Is this the end of the road for this machine?

Any help or wisdom is welcome.

Thanks,

Bob

That is probably why it sold for parts. As old as the machine is the bearing should slide off with no problem. Could be the cracks are more than just cracks where the bearing fits fo the frame of the machine. It may have been dropped on the upper arm. I hope you did not pay to much for it.

Good luck.

On the 111w155 there's a collar on the bearing on the inside that has 2-screws in it that you need to loosen too,are they loose?.Before you try to slide it off you should look for high spots where the screws go & file them off & the bearing will slide of easier.That's usually why the wheel is hard to pull off because the screws loosen & then they burr up the shaft as people sew on it.

@ Geneva, The cracks are out on the arm where the cutaways are in back. I only paid $20. I thought at the least I could learn a bit about tearing down and rebuilding a compound feed machine without any risk of investment. Worst case, I could strip it and have a decent box of spares and maybe a nice garden planter.

@Cowboy Bob, The set screws are out of the collar. I then dripped penetrating oil into the bores in the collar. The handwheel had slipped and the set screws cut a nice groove on the shaft. I turned the wheel while holding the shaft. I basically polished the groove as the wheel turned along it.

Do you drop into the screw bores and polish the shaft?

Thanks for your help folks,

Bob

Where the ridges form is on to of the slot on the shafts.Is the single screw in the back loose?If so sometimes the careful use of a hammer & old flat screwdriver or punch will break it loose,hitting it from the inside.

That bearing assembly is very stuck. The two set screws on the collar are out. The screw in the back of the main body is out and everything is soaking in penetrating oil.

I have lightly tapped it from the inside with a hammer and soft drift.

I'm thinking it's time for a heat gun.

Has any one ever had a bearing this stuck?

The bearings are still smooth and I don't see any wobble to suggest a bent shaft.

I also don't see any rust or heat discoloration that might suggest part seizure.

I'm trying to be slow and careful.

On other machinery, I have been able to use a gear puller.

That top access hole doesn't give me much to work with.

Anybody have an affordable 111W for sale?

Thanks,

Bob

Last year I restored a 111G156 which is about the same machine but with reverse.

My bearing was very stuck too. I almost thought I will ruin the machine when I tapped out the bearing. I was not gentle - really not! As fas as I remember the shaft was slightly thicker toward the hand wheel. Bearing went tight over the shaft when I put it back in but since then it sews like a dream.

I still have a picture

here is a picture of the scars I tapped into the new bearing - you see I was not gentle!

Thanks Constabulary

I feel better knowing that bearing aseembly can be given a "push"

The pictures are a big help.

It appears to be a standard ball bearing set in there.

It seems to make sense to replace it with the trouble it takes to get out.

The bearing assembly looks to be 4 parts: 1 inner collar, 2 outer case, 3 bearing, 4 case cover. Is that right?

Does that assembly come apart once it is out of the machine?

I always assume the balls or races are dented with all that hammering going on.

I didn´t take the bearing apart. I took it off for changing the timing belt.

I have attached a PDF parts list for your machine. Seems the bearing has 3 parts+ screws.

BTW - for some reason I wrote NEW bearing at the above post, seems I had a weak moment. The bearing is not new, I just removed it, replaced the timing belt and put it back in.

When I tapped it out I put the driving shaft against the wall with a thick piece of wood between wall and shaft.

You know what I mean?
