Looking for Singer 234003 timing belt

[FDC]

Hi All!

I'm hoping that someone might be able to steer me in the right direction regarding a 62 tooth metal cleared timing belt for a Singer 51W56. The Singer part number is 234003. 
 

I am interested in the OEM style belt OR a modern alternative and source please. 

Any help would be greatly appreciated.

These have been discontinued many yrs ago,I sure hope you can find one as I have 5 machines here that need them ,I've been looking for at least 10 yrs.

If you guys could give me belt width, tooth size and tooth spacing - I can research.

Had to do same for aftermarket primary drive belt on my various Shovelheads - the pricing on original merchandise for a Primo primary belt drive system here in Europe will make your eyes water and yelp for a chair along with some sniffing salt

Aftermarket units (without the fancy print on them) came to less than 1/2 price.

As far as I can tell from other postings on this here forum, the belt has 62 teeth.

Thanks for the poke tigweldor!

Belt length: 38.75"

Tooth count: 62

Tooth spacing: 5/8"

Tooth width/belt width: 0.665" (not critical, blallpark will do it!)

Tooth length: 0.2325"

Tooth depth (metal cleat divided by 2 is 0.08375" but pulley would allow up to 0.125"

I greatly appreciate your help! Let me know if there's anything else you need!

Hey, right on.

Now with my research European commercial timing belts stop at around 14mm pitch, then take a big hike up to 20mm pitch -with pretty well zilch size in between.

But ya gotta think outside the box.

There are US outfitters of custom timing belts for compressors and what have you not in the car industry.

Try give them a shout : here is a link -- https://www.pfeiferindustries.com/timing-belt-tooth-profiles-and-pitches

Should they have proper profile but too wide a belt - it can be cut with a strap cutter at no real pain

Should they not have what exact size you are searching for - they may connect you to a source that does.

Here is which measurement you need when looking for a belt : 

Pitch -- Belt height (B) -- Tooth depth (T)
