Mentally Exhausted

Pretty much the same expression I had by the end of the day.

You know, I think its actually worse to be mentally exhausted than physically exhausted. The work I put in mentally at school when working with my partner seems more grueling than the actual physical work. I don't mind hes never actually done any mechanic work, everyone has to start some where but when you don't listen to instructions from the teachers or just ignore the procedure and instructions for something ... that can get to be a bit much. For instance today we were installing the back gear box to a Fuller 9 speed transmission. OK just so you know assembled it weighs 750lbs and is pretty much one of the biggest transmissions i ever worked on. The back gearbox weighs about 90 to 120lbs so you need a hydraulic lift to carry the thing its no way you can hold it and install it on to the back of the transmission and engage the gears.

So we have this back box and the instructions say, "using the lift to support the back box, place the back box gears in mesh with the transmission gears and then turn the input shaft and let the box gears pull the box onto the transmission. Do not force the back box onto the transmission as gear binding will occur." OK so i guess he missed the bold print part because when the back box decided that it didn't want to cooperate he broke out the hammer. Now its late in the day i had taken 2 tests and dealt with all the non instruction reading, step skipping, and hammer using I could stand for the day so i sat idly by and watched the back box being pounded on. When the instructor came to check our work and he went to rotate the transmission to see if it was installed correctly guess what.... it was binding! So with this being the 3rd day we have worked on this transmission and time running out we didn't have time to waste. I can see if it was an error because we didn't know what to do and we just did it wrong, but this was a just plain lets get it done who gives a #$^% mistake. So the last hours of the day were spent taking the whole back box back off and this time not using a hammer and it worked. Bad news is we have 3, possibly 4 more days to get the shop work completed or we wont get a good grade. Come Monday the law just might have to get laid down, either work according to the instructions or I'm working alone.
