Sometimes somthing comes through the workshop that is so amazing that one has to wonder how equipment manages to function at all before failing. The image to the right is of a Reeves variable speed pulley, that normally has a solid ROUND shaft.
As you can see by the amount of metallic dust (that used to actually be the shaft) in the bottom of the belt casing, a fair bit of the shaft has been gradually ground down into an almost machined-finish.
Once again, I can assure you that this pulley is supposed to have a solid shaft.
The intriguing thing about this is the Reeves drive itself was still fully-functional and operational when it was returned to us for an overhaul.
The pulley is cast at a foundry in Melbourne’s north, before getting machined by us and finished by a surfacing company in Dandenong.
