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.
