I recently replaced a Tolomatic actuator myself and found the How to replace a Tolomatic actuator https://www.progressiveautomations.ca/pages/replacement-chart guide really useful. I started by measuring the stroke and load, then checked the guide for compatible models. I carefully disconnected the old unit, kept track of the wiring, and mounted the new actuator in exactly the same orientation. Taking photos before removing anything helped a lot, and double-checking connections made the whole process smooth and safe.
