Not strange at all. It's a very good question.
I take it you are referring to Total Productive Maintenance.
I did a Google search and found $699 kits for teaching TPM, and I also found courses that laid out their elements in enough detail to use as a guide, like at the (broken link removed). I am not affiliated with Kaizen Institute.
Most of us do our best learning when applying the theory in a practical way, so if I was you I would do a goodly amount of research and draft lessons in how these mechanics would use the knowledge in their typical work functions.
Of course this means you will need to know your subject much more than a presentation would allow you to get away with, but I feel sure your results would be superior. I also believe you stand a much better chance of them applying what they have learned on the job, which is probably the point of all this.
I would go further and schedule a follow up class or even some focus groups, so they can share their experiences and you can clear up any remaining misunderstandings.
