Well ---there is always a couple/three sides to what goes on in shop/parts house.
Unfortunately there are just as many mechanics that can't explain what they are
after either--so you end up with two standing at parts counter with a huge question
mark above their heads-blind leading the blind.
If I have or had a counter man that was slightly clueless--{can you spin that monitor
around-or do you have any old paper books with show and tell}. I will gladly walk back
/down the parts aisles, lead them to the part, then explain the different varieties that
grew from the same stalk of corn. At the local NAPA store I have been asked I don't
know how many times for help to find a odd part for a customer, especially Ford parts
years back. I have even had them call me at the old shop for help trying to figure out
some odd ball obsolete air brake or air valve related part, because they knew I had
old picture parts books going back to the 70's.
If your dealing with a young guy behind the counter----be easy on them because in
many cases it's easy to intimidate them in front of other customers. And one thing
this OLD HARD ASS remembers--is being intimidated by old shop hands. It's not fun
for them feel like a idiot-no one likes it, But you will gain a friend at the parts counter
when you take the time to help them, and it makes them feel better about coming
to work trying to help others just like you. Your Teaching.

Or when I’m in the field, and calling about the parts, and they can’t really understand what I need - they just text or email me illustrations, and I’ll call back with item number that is on that picture, of the part(s) I need.

I’m a deeply frawed man - but being vague or inefficiently descriptive, or not being able to work with the part guy who is trying to help me - is not one of my sins!!!

This thread made me think of an auxiliary trans failure a few years ago…..

My personal truck was a T800 wide hood. 18 main, 4 speed aux (APO1750-4). I had a driver it in as we had begun his training pulling the 13 axle. Getting out of this particular shipper we’d creep out with the back box in the 1st under so it was crawling and I could steer the trailer. I EXPLICITLY told him do not shift the aux trans until you’re on the highway and can select with minimal load on it.

What’s he do…..damn trailer ain’t even out of the driveway as he’s pulling up a slight grade grossing 240k or so. Our normal routine was no shift until the top of the hill with the entire trailer was up and level. Then and only then would you begin to accelerate and shift the main. Not him. He’s torqued up pretty good, which is hard to tell with that much gear reduction, and decides to shift the aux from 1st under to direct. It sounded like a shotgun going off. Being down by the booster I was lower elevation than the truck and could see the back box dump its oil in about 20 seconds.

This was the result……

If I say “that’s a bummer” - that will be gross understatement!

Did I say TVA-----no I don't think so, no I'm pretty sure I didn't, was I referring to you---
probably because I was referring to the industry as a whole. But for the simple fact you
felt like you were singled out tells me---------------something.

So, do you think he thought he could "show off", or was he that dense that what you told him just didn't register?

Just wondering JY--that was a manual, not air? I rebuilt the 1241's but never a 1750.

It was air. They’re basically the 1241 with a few upgrades, mainly on the input side. The issue we had was input torque vs gross weight. Over 200k it was limited to something like 12,000 ft lbs. Take the first gear in an 18 times 1850 torque and you gotta be really careful.

I was in UT creeping out of a military site. Made the mistake of loading before all my help got there. Nobody watching and with everything in low low I had tons of multiplication going on. Didn’t know there was an old concrete footing under the gravel. Trailer deck crossmember caught it and brought me to a dead stop. Before I could get on the clutch the auxiliary sheared the mount bolts, ripped a PTO cover off and wrapped itself up in the airlines. I had it towed to KW in Salt Lake, ordered parts and fixed it in their parking lot lol.

It’s funny how that stuff goes. Sometimes it’s like “that doesn’t sound normal” and you have time to narrow down the origin. Others it’s “that doesn’t sou….kaboom. *** was that. Oh, I just ran over my own driveline.

Indeed! A new noise or slight vibration that you can't isolate and pinpoint, and I tell myself and our guys to pay attention because it will show itself - hopefully before the carnage!

I struggle with imagining new noises. When everything is 20 years old, it usually is making noise anyway. Just have to try and determine if it's just the same old noise getting a little louder, or if it's something new and need to be concerned......

One place none of that really fits is recovery. Too many odd sounds covering normal sounds &
nothing is wrong, the sound of metal tearing---the next sound would be cable/hook in flight.
Been there with that one.

Can relate on parts mo rons. Pete I was driving several years ago 13 spd Eaton and shift knob leaked like a open hole. Stopped at Truck Centers Foristell MO, guy behind the counter as I walk up, explained needed 13 spd Eaton shift knob Red splitter control, Blink Blink, got a S/n? Gal in the back hollers I got it, comes out shoos the Boy off. Apologized he had not been trained better. Bought the knob kit had it on and gone twenty minutes with two Adjustable nut rounders.

One of my co workers noted a odd vibration and commented seemed instantaneous. We were picking up for two different jobs. Get back to yard his truck in shop, drove it back PD engaged as Intermediate drive shaft was Gone, beat marks everywhere, spit uJoint at back of front diff, shaft whipped and the also Dry Failing rear joint had enough. Shaft went to roadside. Week and half awaiting two yokes and new shaft.
