Can we talk about the idea that you should always replace both sheaves on a traction machine at the same time? A foreman in Cincinnati swore by it, but I've had a single sheave running fine for over 18 months now.

Your foreman had the right idea. Replacing both sheaves together keeps the load even across the machine. Running a single new sheave with an old, worn one puts extra stress on the new part and the cables. You might get lucky for a while, like your 18 months, but it's asking for a bigger failure down the line. It's a cheap insurance policy compared to a full breakdown.

Exactly. It's not just about the sheaves wearing out at the same time. The old one has grooves worn in a certain way. A new sheave sits differently. That mismatch makes everything work harder. You're basically speeding up the next break.
