In the process of rebuilding a Sperry Rand Wedge and ran into a stumbling block. The chain from the transmission output shaft to the primary drive is a triple strand chain. It falls somewhere between a #40 standard and a metric triple strand. Took it to Motion Industries and they cannot find a match. Anyone out there with a solution? Can I run three individual chains or will that decrease the strength too much? As always, I appreciate any info you can provide.
search e/bay for triple #40 chain or look up MSC or Granger.
I got a new one for my wedge back in the day but not at my shop to see where I got it.
I do know Tsubaki makes it and there one of the Best chain people out there.
Here is the in you may need ? it is e/bay auction # 291675003881
Thanks. Saw that one on Ebay earlier. The roller dimensions and overall width do not match #40 chain. The metric size solves the roller diameter but not the overall width. The new triple strand adds an additional plate that increases the width. Maybe that will not effect the overall performance. Have to get to my wedge to measure the sprockets. Definitely don't want to change those.
To get you up and running you can always run 2 strands on the outer sections .
I wondered about that. Not expensive so maybe I can get three separate strands to fit for now.
It is worth a try ?
Hay Bud did you get your wedge up and running ? What engine do you have in it also ?
Just thought I would check in on ya to see how you made out ?
Goods sources tell me that this chain is same as primary chain on BSA and Triumph motorcycles... try this. Speed & Sport :: Primary Chain, Triple-Row
