similar to having TV on during lightning storm and house or near by tree is struck. current will follow through house and take-out plugged-in appliances.

also keep in mind; the braided ground strap is a duel purpose item. not only for ground but also it is made of the braided material to act as a weak link in system should a problem arise. it will melt in half intentionally when major short happens.

got that one covered 100%. changed many of the braided ground straps .

after the mechanic section closed and I was put into driving: the FL was what I was given. worked well= short wheel base; excellent turning radius for the narrow alley tight turns. company colors pink/blue didn't make a difference to me . cup coffee/ doughnut to wash kid and it was cleaned every week. took it away and I was given newer plastic ford; didn't like it at all.

I'd say some where in time the hand brake assembly with drum was eliminated. what year truck? is there/was there a hand brake ?

thing about the "early mechanic days" , if you had half an interest in your job, you learned and studied. like high school what you put in is what you got out. thing is not much attention was paid to minor items as a thermo or maxi dyne. if it was gold it was a maxi anything else was a mack. to see the start of the computer age in trucks wasn't easy to accept. how could an engine 250 hp become a 300hp with this little box plugged it. not a wrench involved. also 300 plus rings a bell.

he is the victim !::he had to use taxpayers money to buy those drugs when his daddy should have gotten them for him for free. poor lad.

memory is correct the 675 becomes a 676 with the tip turbine. I do recall a 300 /315 version talked of way back then when they were NEW products. wasn't a lot of rebuilding then being new and the slogan "built like a Mack truck meant something.

enlarged to max ;that's not a crack .

is that not a crack in liner ??? 542c ??

pulling both as one unit -no problem . except when only lifting device is two hands and strong back. the reassembly done MANY times as one unit works. prefer reassembly as two separate units myself.

might have to keep some pictures close by on reassembly. at least the picture showing location of the three odd ball studs used to clamp angle bracket for tip-turbine fan(intercooler) brace.

toolbox always had a drawer with the plastic caps for things such as open ports on injection pump. any work activity such as the removal of heads put dirt/grit in those holes. at least a rag to cover. just sayin. looking at those excellent pictures has the brain cells going "remember when " the fun days. after assembly ; best part is sound engine makes on start up.

only one gummed up stud !! you came out lucky. many times due to time constrains head gaskets are changed with heads still clamped together by manifolds. it will work BUT life span of the gaskets may be shortened. when heads are set/torqued individually torque per head is tad more accurate.

seems time is closing in on all the ole timers; like Tex Ritter says in "Hillbilly Heaven song". I can't bring my toolbox with me ; think the heat will melt everything. I do my best Not to think of people in past tense. they seem to hang out even after they leave here. Glen Akers Left a wealth of knowledge for all to learn by. at Waterbury Mack it is Ole Man Al Dixon in the machine shop. His knowledge would fill a complete set of manuals.

you really know how to make a guy feel bad , LOL .. 8 am I was at set up for Kof C Church function; left for short term watching the clear skies thinking " I could make it to Bethlehem to see up close the B-73 then make it back in afternoon for K of C event, didn't make Bethlehem figuring I could make the Sunday half. we all know locally it was clouds and rain Sunday . that picture of the B-73 between "those other brands" is fantastic ; LMAO !!. it says - I'm older then you , see if you look this good when your my age !! Thanks for pictures..

I know ;; just have to keep bob on his toes. LOL . can't figure why my wife gets upset walking through a store and I say" there's a nice pair of t- ts. 😱

"sick puppy" LMAO !!! are we drinkin or bathin.

will be against my better judgement to ask for explanation of that statement ! nice truck from my point of view !! now how did twin peaks compare. LOL

interesting when the fins on outside are bent over from pressure washing out to in .looks clean and see how good we did blasting crap deeper in to cores. but it's too much work to clean from fan side out.

real nice looking unit, not over done. right color and chrome .. AND period correct "fish bowl 'fogs .

I like sea food also . unfortunately i get too much == I married a crab!!🤣

i do remember the ability to lock a horton fan; can't recall viscous being able to lock ? far as this unit = another question is "with warmer weather coming , truck runs warmer "" .. by chance warmer temps high enough that AC is being used?? answer -yes ::: now temps in front of radiator even hotter which will show on gauge. todays world with 3 cores in front of fan . collection of bugs etc greater also. have another brand of truck working on today for same issue. have to be extremely careful if using air hose or pressure washer to clean cores. I separated the AC core expecting the worse (truck hauls hay ) = actually wasn't that bad between cores. AC expansion valve/ dryer on order. the joys of retirement.

consider accuracy of the gauge could be off a tad. stays in green high side except able. big question is :: "fan stays running?? " as joey stated a viscous fan is continuously spinning ; unlike a horton which when not needed goes for the ride. viscous will spin appear to be doing something yet NOT fully engaged for engine cooling. the temp running high side could be due to number of variables. outer temp /load weight pulled/ amount of bugs etc in radiator=intercooler- ac cores. if this IS a viscous fan number one place to look first the bi-metal plate front center of fan hub, dirt/ crap collects stopping plate from flex pushing in plunger to transfer viscous fluid to second halve engaging fan.

another change in times " company had a roll of cable= speedo or tach with an assortment of different ends ; also the proper crip tool for fixed to cable drive ends. Jojo to answer your question above ::: most speedo spiral gears only slid onto the yoke. tightening the yoke nut compressed spiral against yoke/bearing. didn't require much for tight was only mated to speedo cable. as with much back then life was better. time killing on shuttle job , I would disconnect the speedo cable ride the highway after 5pm in summer and see alot. never showed a mile on speedo. can't have that fun today.
