General Service time benchmarks

[joeclark]

Hi Ladies and Gents,
I am searching for some benchmark service times for general equipment such as excavators, dump trucks etc.
I have just completed a 5000hr service on a customers ZX350, but due to some "technical difficulties" with my service rig I spent way more time at the job and the process was longer than I intend to charge out...
How much time should I charge the customer and still keep a straight face. I was onsite for 9 hours but should have taken much less time.

I didn't find the right solution
