Can't help in any detailed way. I had the PW version Burro crane, 3360 and serviced the motor years ago, I clearly recall the cab was a tight fit requiring very positive effort to remove. However, I don't recall how much of the crane was disassembled prior to removing the cab.
So my reply is more of a bump for your thread in the hope that the truly knowledgeable folks here can help you out.
Be patient and you will get all the help you need.
