Singer 111w103 new belt seems to have slack?

[ksteers]

I have replaced timing belts on numerous Singer 111, 211 etc.      

Generally when i remove the huge bushing behind the handwheel, the top shaft sags just a bit, allowing for easy belt installation.   when replacing the Bushing, it pulls the belt tight as a drum head.

this singer 111w101 (101 is overstruck with 103 tho) seems to have slack in the timing belt.   it sews beautifully, but in my minds eye, it shouldnt be!

This singer doesnt have a clutch mechanism.    i purchased a Honeysew 224195 belt which i thought was good for all 111's etc.

 

Curious if the belt tensions vary on some models?

 

tx to all of you out here on this Forum!   i learn much from reading rather than posting:-)

How much slack are you talking about? A little slack is not uncommon especially on the older timing belts with metal cleats / braces.

What do the parts list say? Do the 111 models incl. your 101 subclass use the same timing belt? If yes then it maybe be a manufacturing error. Have you used timing belt from the same source / manufacturer before? Or have you bought them here and there.

the deflection feels like more that 1/4 inch.    All the 111w general manuals mention 224195.    After digging i found the 111w103 manual and it makes mention of a 224103 fabric belt also.  i believe it all depends on if there is a safetly clutch in there.   I dont recall where this neoprene belt came from, I'll be calling Bob at Toledo Industrial later today.

A Moderator can close this thread.  Thanks y'all

I have a tool box full of used 111 parts.  Many sprockets, obviously a wear item.  A employee who had a very worn 111-153 I replaced belt and had to built a tensioner to take up slack. You may need new sprockets.

I´m pretty sure the cog wheel with the safety clutch has the same dimensions as the plain one. Why should it be different when they use the same timing belts?
