Trusty tractor Gearbox chains

[howardman 30]

 I am  restoring a 1947 single speed trusty tractor  that was outside for a very long time  and need to source new gearbox chains  (3). have tried  motorcycle shops but nobody seems to have a match. Anyone  got any suggestions?

measure the width and pitch, it's almost certain to fall into a standard type i.e. 3/8, 1/2, 5/8"

 

https://en.wikipedia.org/wiki/Roller_chain

 

you can then cross reference to:

 

https://www.usarollerchain.com/Metric-Roller-Chain-Chart-s/4870.htm

 

then buy from 

 

https://www.engineersmate.com/products/BRITISH-STANDARD-ROLLER-CHAIN/C106058

 

or 

 

https://www.bearingboys.co.uk/British-Standard--1305-c

 

that's where I'm buying it from at the moment...

 

hope this helps, if you get stuck, ping me the width and pitch.
