don't even get me started on this one
an example
about 1983 i had a canadian group come in on the hook of a wrecker in a winabago
with a blown engine,,
now mind you we were a big truck shop, semi's and trailers , class 8 and all that
not some pissing motorhome repair place.
but they were stranded and we took it on.
it took nearly 40 hours to remove the blown engine, build up a long block and reinstall it in the chassis and finish it up.
it ran for 30 minutes before a rod brg failed.
the engine supplier offered 4 hrs labor!!
and we never even got that,, we did however get another pos engine from them that thank god worked.
oh yes,, i think we made about 200 dollars markup on the first long block.
another thing to keep in mind
you state a common available 130 dollar brg?
how common? did he bring it? or did he have to take the time to source it locally?
the rub is there are a jillion different suppliers of brgs as with all parts and pricing is all over
the place.
he may have paid 130 bucks, and then again he might have paid 250 bucks for it as well.
i get this all the time, "hey i can buy that starter for 169 dollars"
and i reply "yes and i can too, but i refuse to sell that cheap part because of high failure rates"
all i am saying is there might very well be other circumstances envolved,
the bottom line is,, did he get the machine fixed? in a timely fashion? is he a guy that will stand in front of a truck for you and your company? come out any time? day or night?
weekends and holidays?
if so then buck up and pay the guy, you got a gem and an allie that will make or save you far more money than your perceived overcharge on that brg.
btw,, i have been screwed, blued and tattoo'd by more than one machinist in my time as a mechanic as well, trust me you don't wanna go there.
