1st day on the job!
The engines are bigger than "normal". So I get to use comically large copies of common tools
Lots of usage of heat to mount or dismount parts, especially bearings.
Firstly I took apart a AC asynchronous motor, pretty normal, from the early 60's: the client had set a max work time of 4 hours, it needs at least 7, so it's going to get recycled (the part that holds the bearing on the shaft side is out of true thus needs a new race). The UVW/XYZ was also reversed.
The second one comes from a refinery in a tropical place (no idea where), and was build in 1941, rebuilt in 1954, revised in 1983 and now in 2015 and still has 20 or 30 years life in it - electric motors last long!
This model, in constant use in a tropical place, only needs it's grease replenished every tens years. And that's it. No other maintenance.
Got to use my hobbyist soldering abilities to repair broken heat sensor wire in a weird place that people were trying to get anybody else to do.
Pretty cool on the whole,
