looks like you got the 'posidrive' head there not the US crosshead, they take a different screwdriver bit as the taper is different.. but for your use should be ok if you use a handtool.
I've found that the aircraft parts suppliers can be good for looking for oddball hardware, NAS, AN or MS series for bolts, screws, nuts and various quick releases for panels like Dzus... not nearly as cheap as automotive parts but they are not chinese grade 2 crap and meet strict manufacturing standards... lots of on-line catalogues too.. generally fine thread is standard.

I live in that region and what you see on TV of a bad day on 'the coke' is truly bad for driving, mother nature at her worse in bad terrain.... the highway is a major route of commerce now that Vancouver has become a hub port, unfortunately while there are many qualified professional senior drivers the race to the bottom for price has put lesser skilled steering wheel holders in charge of 140,000lb super B's, you know, the ones with flip flops and wraparound stetsons, and the show is very careful so as not to accent them.
the alternate routes in bad weather are mostly two lane highways resembling in places mere goat tracks, the Coquihalla highway had its pundits when built in the early 80's, it was built in a well known bad snow region but it went ahead anyway. Truckers avoided it when new, there was a toll and one really steep hill that wore out brake linings, they preferred the old flatter winding route on Hwy 1....
all in all the TV show is one of the better presentations of "reality", what you see of the stars is pretty much what they are, Jamie can be a dickhead, his brother is far smarter and Al can tow me anytime, the business of towing doesn't attract those with academic backgrounds as it takes a different type of smarts to do that work....
I remember they also had a TV show about another towing operation, on the Donner Pass IIRC... but as B Mack stated, the Snoqualmie can be a bad place too...

KSC... that Merc was only doing 'domestic' in Saudi, not 'lnternational' as on the door, not with a day cab and those sand tires.

since everything in the engine is assembled with "fasteners" should we now weld everything up to comply with warranty???

or like when the factory trains you and than the shop doesn't get the tools, parts or manuals to actually do the job. Paul
or..... when the company sends the mechanics on training courses ($$$) to increase their knowledge but not the supervisory management... I asked them for an hour to road test in a hilly area to prove my theory of why we were getting fuel problems on a Cummins ISL coasting downhill, they said "no way".. they told me to change the $6000 fuel pump, after all that work and money we still had the same problem.... then they allowed me the road test with a laptop and I changed the $150 fuel return line with a hose flapper in it... and they got the attaboy for fixing the issue... go figure..!!!!

As for Brasilian jokings now I'm ready to state anywhere that Russian roads are one of the safeties in the world!
LOL ... youtube has videos to prove you wrong... Scania vs Lada seems to be a common scene in Russia but nowhere is perfect for road safety, I bet they have bad drivers in Antarctica too..
I don't know whether to call those particular Brazilian drivers skillful or fools but in general they have some extreme conditions to deal with and their roads are by far not up to world standards.

Kind of an interesting parallel here. Before WWII we thought the Japanese were only able to copy things and had no skills to design and produce advanced items. We are have been made the same assumptions mainly about China, Mexico and India. Now it has come back ten fold to bite us in the butt.
this is the guy who brought Japanese production up to what it is today, part of MacArthur's team after ww2 he created what we term today as the "quality system" in production....

take them back to your brake supplier with the drum mounted on the hub and have them machine the shoe to match the drum profile, but give 0.010" clearance to wiggle the drum on...
shoes with rollers can have up to four sizes of roller, max oversize of drum is cast in the drum info, and shoes can come as std, X or XX.... most common size I use in 14.5 and drums can wear up to 14.833 before scrap.
unless you are putting on new drums with new shoes and linings (which is now recommended given the crap drums out of China) you need to have machining done to give 100% contact from day one, otherwise you will only have a small contact area until the linings wear down some.

The Allison control lever is simply a fore-aft motion, many use a cable shift.. my first thoughts were that this truck may be used where a gear is to be held and the "gate" is set up for that purpose..

the tire must have "regroovable" on the sidewall... !!!
look up... title 49 CFR 569.3 and .7 for the rules and specs
the good tool can cost $800+, not sure if the Chinese have copied it yet....
nick the cord and the recappers will reject it, there is a minimum for the depth of material to be left in bottom of groove and not many tires today give the extra meat... works better for older bias tires
if the tire is close to the age limit and you know the cappers will not touch it, then it may be worthwhile, but in general the industry has gone away from it, maybe the small guys still do it for trailers..
not allowed on steers
some bus companies still doing it for tag tires, might be easier to find a guy that does it for them..

As I've said in other posts, none of this "breakthrough" technology is new, in fact some of it is 100 years old... it is the advancement in materials and controls that have brought this back into vogue...
https://en.wikipedia.org/wiki/Tilling-Stevens
petrol-electric and battery electric were commonplace before advancements to diesels in the early 30's made them less efficient.... though they soldiered on as light industrial machines until this "re-discovery" of late.
today's decision makers need to formulate a singular national plan to standardize a grid of support if we are to advance to electric power... do we have enough grid power now and in the future to support this change away from fossil fuel, and do we want the cost to provide this energy to be more than it can be sold for, will the public purse be financing it.... and taxation will follow as the government needs a replacement revenue stream as gasoline/diesel sales fall...
fleet and bus management have a tough decision to make as to which technology and supplier to work with, bus fleet planning math is a 20 year life for a city bus so will the supplier support this and are the leaps in technology going to obsolete the fleet in 8-10 years?... tough call...

It seems the better book stores for our varied interests are on the other side of the Atlantic, this one has been around for a while
https://www.oldpond.com/machinery/trucks-and-heavy-loads.html?___store=default&limit=60
I use a couple of sites to find odd titles, of course there is ebay and amazon too..
https://www.abebooks.com/ https://www.bookdepository.com/
biggest limitation, other than the price!!!!, is shipping and currency conversion
it's only money, spend it before the kids get a chance to do so...LOL

Douglas sold their prototype DC-4E airliner to Japan prior to WW2... it was then used by Japan as a basis for a bomber...
https://en.wikipedia.org/wiki/Douglas_DC-4E
"The Douglas DC-4E was an American experimental airliner that was developed before World War II. The DC-4E never entered production, but its failure resulted in an entirely new design, the DC-4/C-54, which proved very successful. Many DC-4E design features found their way into the Japanese Nakajima G5N bomber."

it certainly is a race to the bottom, UK driver's have the same issue....
if you could imagine all US states being independent nations with controlled customs borders, different driving laws, different rates of pay, different social support etc.... would there be a fight if the drivers from say Alabama drove internally within Oregon..???
then you form a "union" of all the "states" and everyone drives wherever they want but at rates of pay of their home state... and the shippers figure that by hiring that same Alabama driver to move a load from Oregon to Florida at a lower rate of pay... is that called a "free market"????
that's trucking in the EU

with the large surface area of a semi and van trailer... it can't be far off when a flexible skin of solar receptor material could be wrapped around everything... in CA there seems to be a lot of sunshine!!
or just strap a genset behind the cab?... and call it a hybrid..!!
trailer technology is moving along too, braking energy recovery and solar powered reefer... not much work left for us mechanics to do, time to train up.... or retire.. LOL
